Agronomic parameters assessment in hydroponic tomato crop
Provedor de dados: 75
Autores: Herrero,Baudilio; Blázquez,María Elena; Cristóbal,María Dolores.
In this study we present the results of a comparative analysis of nutrient solution (NS) recycling and non-recycling treatments in hydroponic tomato crop. The established aims are to evaluate water consumption, pH and conductivity variation along the productive cycle in both treatments, to establish the differences in fruit yield and to assess the viability of the recycling system. Watering times and drained nutrient solution volume were counted on a daily basis. Emitter and drained water samples from both treatments were analyzed once per week in the Agricultural Institute of Fraisoro (Gipuzkoa). Tomato samples were collected, weighed and measured three times per week once the harvest had started. There was an 8% reduction in water supply; irrigation...

Analyse du cycle de vie d’un biocomposite
Provedor de dados: 5
Autores: Le Duigou, A.; Davies, Peter; Baley, C.
In addition to the impact on climate change resulting from the use of non renewable resources [1], the depletion of existing fossil fuel sources is inevitable. A major change of strategy is required. This article presents an analysis of a Flax fibre/PLLA biocomposite life cycle compared to common glass fibre reinforced polyester composites from manufacturing to mechanical design and end-of-life. Environmental impacts have been assessed by Standardized method called Life Cycle Analysis (ISO 14044). Flax fibre/PLLA biocomposites manufactured by film stacking have, for similar mass, tensile modulus close to that of Glass/Polyester. Besides being compostable at end of life, biocomposites have been proved to be recyclable which makes it possible to keep the...

Optimal feedback strategies for bacterial growth with degradation, recycling, and effect of temperature
Provedor de dados: 5
Autores: Yegorov, Ivan; Mairet, Francis; Gouze, Jean-luc.
Mechanisms of bacterial adaptation to environmental changes are of great interest for both fundamental biology and engineering applications. In this work, we consider a continuous-time dynamic problem of resource allocation between metabolic and gene expression machineries for a self-replicating prokaryotic cell population. In compliance with evolutionary principles, the criterion is to maximize the accumulated structural biomass. In the model, we include both the degradation of proteins into amino acids and the recycling of the latter (ie, using as precursors again). On the basis of the analytical investigation of our problem by Pontryagin's maximum principle, we develop a numerical method to approximate the switching curve of the optimal feedback control...

Autores: Alexy, Pavol; Anklam, Elke; Emans, Ton; Furfari, Antonino; Galgani, Francois; Hanke, Georg; Koelmans, Albert; Pant, Rana; Saveyn, Hans; Sokull Kluettgen, Birgit.
This paper identifies knowledge gaps on the sustainability and impacts of plastics and presents some recommendations from an expert group that met at a special seminar organised by the European Commission at the end of 2018. The benefits of plastics in society are unquestionable, but there is an urgent need to better manage their value chain. The recently adopted European Strategy for Plastics stressed the need to tackle the challenges related to plastics with a focus on plastic litter including microplastics. Microplastics have been detected mainly in the marine environment, but also in freshwater, soil and air. Based on today’s knowledge they may also be present in food products. Although nanoplastics have not yet been detected, it can be assumed that...

Recyclage de déchets d'aquaculture marine - Caractéristique d'un effluent de pisciculture : l'écume
Provedor de dados: 5
Autores: Divanach, P.; Sube, J.
Previously to its use as culturing medium for algae, we have studied the various characteristics of the sewage extracted from marine fish rearing ponds, through a purificating system called "foamer". Qualitatively, this sewage differs from the sea water which produced it on various points : It is richer than the water in Organic Carbon, Organic Nitrogen, Ammonia, particulate matters, phosphorus and varied metals. However the concentration factors are not constant and they change in time. This sewage is toxic for some group of animals and this toxicity varies with the concentration but also the age of the product. Finally, it is eutrophicant and this richness enables to the growth of algae for long periods but the boundary between toxicity and eutrophy Is...

Effect of recycling on mechanical behaviour of biocompostable flax/poly(L-lactide) composites
Provedor de dados: 5
Autores: Le Duigou, Antoine; Pillin, Isabelle; Bourmaud, Alain; Davies, Peter; Baley, Christophe.
The biocompostability of natural fibre-reinforced biopolymers, also known as biocomposites, makes them an attractive alternative to glass fibre-reinforced petrochemical polymers. The aim of this work is to study the capacity of flax/PLLA (poly(L-lactide)) biocomposite (20% and 30% fibres by weight) to be recycled. Mechanical properties were evaluated initially, and shown to be similar to those of glass/PP and superior to hemp/PP and sisal/PP composites. Then after repeated injection cycles tensile properties were shown to be conserved until the third cycle. Matrix degradation and fibre aspect ratio were followed using molecular weight measurements, thermal and rheological analyses, image analysis of sections and SEM fractography. These techniques revealed...

Biogaserzeugung ohne Flächenkonkurrenz  auf Basis von Zwischenfrüchten, Kleegras und Reststoffen
Provedor de dados: 21
Autores: Szerencsits, Manfred; Erhart, Eva.
Cover or catch crops have beneficial effects for soil, water, erosion, etc. If harvested, they also provide feedstock for biogas without competition for arable land. The latter also applies to clover grass ley or other residues on organic farms without ruminants and for manure. With an explorative approach, combining field experiments and data collection of practical implementation, we investigated achievable yields and identified recommendations for practical use. Gross energy yields of cover crops varied between 700 and 2000 m³ methane (CH4) ha-1 in Austria. The energy return on energy invested (EROI) ranges from 4 to 7, if biogas is upgraded and com¬pressed for biofuel use. Therefore, about 1000 m³ CH4 ha-1 are remaining as net energy yield from 4.5 t...

Auswirkungen der Fermentation biogener Rückstände in Biogasanlagen auf Flächenproduktivität und Umweltverträglichkeit im ökologischen Landbau bei viehloser Wirtschaftsweise
Provedor de dados: 21
Autores: Stinner, Walter; Möller, Kurt; Leithold, Günter.
Problemstellung/Ziele:Analog zur Entwicklung im konventionellen Landbau ist auch  im Ökologischen Landbau eine zunehmende Tendenz zu viehloser Wirtschaftsweise  festzustellen. Viehlose Betriebe können auf die Vorteile des Kleegrasanbaues (N-Versorgung,   Unkrautbekämpfung) kaum verzichten. Üblicherweise wird der Aufwuchs  gemulcht und auf der Fläche belassen, ebenso die übrigen Rest- und Koppelprodukte  (Stroh von Getreide und Körnerleguminosen, Zwischenfruchtaufwüchse, u.ä.). Damit  können erhebliche N-Verluste verbunden sein, zum Einen als Ammoniakfreisetzungen  beim Abbau des Kleegrasmulches (u.a. ANDREN, 1987), zum Anderen durch Minderleistungen  der Stickstofffixierung gemulchter Bestände, die mineralisierten Stickstoff  aufnehmen und dabei die eigene...

BioBiogas - Erfahrungen bei der Erzeugung von Biogas im Ökologischen Landbau
Provedor de dados: 21
Autores: Grieb, Beatrice; Gerlach, Florian.
In der Pionierphase vor der Jahrtausendwende waren Biolandwirte stark vertreten unter den Vorreitern der Energiegewinnung mittels Biomassevergärung. Kein Wunder, schließlich bietet diese Form der Bioenergieerzeugung in der Hand von Landwirten die Chance, in der Biomasse enthaltene Nährstoffe nach der Vergärung in den eigenen Pflanzenbau zurückzuführen. Heute, da in Deutschland ganze Landstriche von der Biogaserzeugung geprägt sind, fristet die Methanerzeugung auf Biobetrieben ein Nischendasein mit wenig Zuwachs. Bei entsprechenden Voraussetzungen jedoch könnte die Biogaserzeugung auf Biobetrieben (»BioBiogas«) nicht nur einen wertvollen Beitrag zur Erzeugung von regenerativem Grund- und Spitzenlaststrom leisten; sie könnte – bei sinnvoller...

Autores: Singer, Christoph; Cergel, Sylvia.
Die einzige derzeit bestehende, voll wirksame und zugelassene Pflanzenschutzmaßnahme gegen verschiedene Schadpilze im Ökologischen Landbau sind Zubereitungen auf der Grundlage von Kupferverbindungen. Dies führt jedoch zur Anreicherung dieses Schwermetalls im Boden, was ab gewissen Konzentrationen zu toxischen Effekten führen kann.  Eine Herangehensweise im Ökologischen Landbau ist es, die natürlichen Widerstandskräfte der Pflanzen gegen Pilzinfektionen zu unterstützen und zu stärken. Das Ziel dieser Studie war es, das Potenzial von Traubenkernextrakten zu untersuchen, um die Pflanzen im ökologischen Weinbau gegen den Falschen Mehltau (Plasmopara viticola) und im ökologischen Landbau gegen weitere Schaderreger, wie den Erreger der Kraut- und Braunfäule...

Upcycling food leftovers and grass resources through livestock: Impact of livestock system and productivity

Autores: van Hal, O.; de Boer, I.J.M.; Müller, A.; de Vries, S.; Erb, K.-H.; Schader, C.; Gerrits, W.J.J.; van Zanten, H.H.E.
Consumption of animal-source food is criticised, among other reasons, for its relatively high environmental impact. It is, however, increasingly acknowledged that livestock can contribute to nutrition security if they upcycle low-opportunity-cost feed (LCF) – food waste, food processing by-products and grass resources – into nutritious animal-source food. So far, however, no study explored the allocation question “to which livestock should we feed what LCF to maximise livestock's contribution to human nutrition”. Here we optimise the use of the LCF available in the EU, using a model that assigns LCF to those livestock systems that maximise animal protein production. We included the five most common livestock systems in the EU – pigs, laying hens, broilers,...

Autores: Vaarst, Mette; Tibasiima, Thaddeo; Dissing, Aage; Dissing, Inge Lis.
This book aims at telling about our common learning in projects in different parts of Uganda, where farmer families and local communities have worked since 2009 to improve their livelihoods and environments based on common learning about organic and agroecological farming, joint efforts for better livelihoods and community development, using the approach of ‘Farmer Family Learning Groups’ (FFLG). This way of working together takes the ‘family approach’: our starting point is whole households working together on each their individual farm. As opposed to the methods where farmer groups work on demonstration farms or demonstration plots, this project is based on groups, which work at each other's individual farms, not focusing on one enterprise, but on...

Som resultat af projekterne kan drages følgende hovedkonklusioner om kompostering af fæces fra mennesker: Fæces fra de undersøgte typer af kompostbeholdere bør ikke anvendes til jordbrugsformål uden viderebehandling, da dette skønnes at være behæftet med hygiejne- og sundhedsrisici. Det skyldes, at der ikke blev dokumenteret egentlige termofile temperaturstigninger i fæcesmaterialet i komposttoiletenhederne i Hjortshøj, Dyssekilde og Sverige, samt at fækale indikatorbakteriers antal varierede voldsomt, og der ingen entydig tendens var til forekomst af lavere kimtal ved lange opbevaringstider af de opsamlede fækalier.

Provedor de dados: 21
Autores: Jovchelevich, Pedro.
The purpose of this work was to evaluate the influence of moon rhythms on yield of carrot roots under biodynamic management sowed in different dates. The experiment was carried out over a two period on a biodynamic farm, in Botucatu, São Paulo State, Brazil. Rhythms were tested observing the effects of seeding at different planting dates. The experiment was performed with four randomized blocks and 31 treatments (different dates) in 2005, and fourteen treatments in 2006. The harvest was made 82 days after sowing. Effects associated with planting at a specific lunar position were measured by the deviations from the trend curve. The following characteristics had been evaluated: fresh mass of roots and leaves and dry mass of roots. Dry mass was the only one...

Ekologiskt kretsloppsjordbruk: metod att minimera växtnäringsförluster till Östersjön
Provedor de dados: 21
Syftet är att undersöka hur mycket överskottet och förlusterna av kväve och fosfor kan minska i jordbruket genom lokal och regional anpassning av växtodling och djurhållning i enlighet med principerna för kretsloppsbaserad ekologisk odling. Studien genomförs på utvalda ekologiska typgårdar med till den egna foderproduktionen anpassad djurhållning i för landet representativa avvattningsområden. Resultaten från balansräkningar och mätning av växtnäringsförluster ligger till grund för jämförelser med dagens jordbruk och förslag till sådana förändringar av jordbrukets struktur som kan leda till minst en halvering av förlusterna. Projektet ingår som en del i det av EU delfinansierade BSR INTERREG III B-projektet ”Baltic Ecological Recycling Agriculture” (BERAS)...

Fødevarernes andel af klimabelastningen
Provedor de dados: 21
Autores: Olesen, Jørgen Eivind.
Produktion og forbrug af fødevarer er ansvarlig for et betydeligt bidrag til de globale udslip af driv-husgasser. Udslippene skyldes direkte udledninger af drivhusgasserne metan (CH4) og lattergas (N2O) i forbindelse med produktionen. Disse drivhusgasser har henholdsvis 21 og 310 gange krafti-gere drivhuseffekt end CO2. Drøvtyggernes fordøjelse er den største enkeltkilde til metan udled-ning, desuden kommer der metan fra gødningslagrene. Lattergas dannes, når kvælstof omdannes ved mikrobielle processer i jorden. Derfor øges udslippet af lattergas, når jorden tilføres kvælstof-gødninger. Landbruget har endvidere et energiforbrug (direkte og indirekte), som også bidrager til udledning af CO2.

Kompostering er metoder der organisk materiale, for eksempel matrester, hagerester, halm og/eller husdyrgjødsel, omdannes til næringsrik jord og humus.Organismer som trenger god tilgang på luft sørger for omdanningen, og komposten bør derfor stelles som et levende dyr. Den må ha en riktig blanding av mat (organisk materiale), vann og luft. I tillegg må den vendes og blandes. Sluttproduktet, kompostjorda, har ulike kvaliteter og bør brukes deretter.

Meeting P Demand in European organic farms: Is it time to change the Standard?
Provedor de dados: 21
Autores: Cooper, Julia; Loes, Anne-Kristin; Hörtenhuber, Stefan; Mäder, Paul; Magid, Jakob; Oberson, Astrid; Möller, Kurt.
Organic farming standards regulate allowable nutrient inputs according to the core principles of: reliance on renewable resources, recycling of wastes and by-products of plant and animal origin, and feeding of plants through the soil ecosystem and not through soluble fertilizers, balanced against a goal to produce high quality products with a minimum level of contaminants. These criteria are applied to the list of currently permitted inputs in organic agriculture, known as "Annex 1" of the European Commission Regulation EC No. 889/2008. This list currently excludes some potentially useful sources of societal waste (e.g. some sources of household waste and digestate, sewage sludge), but allows other sources which may pose higher risks according to some...

New techniques in olive mill wastewater treatment (OMW)
Provedor de dados: 21
Autores: Arvaniti, E. C.; Zaglis, D. P.; Papadakis, V.G.; Paraskeva, C.A.
A new cost-effective system for complete exploitation of OMW is suggested, offering a viable solution to the problem of OMW disposal. Use of the proposed separation techniques prefiltration (PF), Ultrafiltration [UF], nanofiltration [NF], and reverse osmosis [RO]) produce byproducts that might include additional benefits. A pilot plant was developed in an olive mill operating in Achaia (Patras, Greece) during an olive harvesting season. Large volumes of OMW produced daily were treated systematically in a semibatch procedure to identify problems relevant to long-term behavior and reliability. The study showed that a fraction of pure water up to 75% can be recovered. Also fractions are isolated that contained concentrate nutritious and polyphenol content...

Optimizing nitrogen utilization by integrating crop and animal production
Provedor de dados: 21
Autores: Seuri, Pentti.
The farm model was built according to the data from 9 Finnish organic farms. 20% of area produced cash crop and 80% was used as fodder in milk production on the farm.  The model indicates that there is high potential (up to 30% compared to Finnish average) to reduce nitrogen losses in agriculture. The key factors are integration between crop and animal production, limited nutrient intensity according to the system itself and BNF.     The crop rotation used in model can support milk production with relative high intensity. In this  model no external fodder is used, however, it may be necessary to have a small amount of high quality processed protein concentrate, if the annual milk yield exceeds 8000 kg/cow. Crop yield by means of nitrogen yield was about...

Evaluation of organic matter stability during the composting process of agroindustrial wastes.
Provedor de dados: 21
Autores: Tittarelli, Fabio; Trinchera, Alessandra; Intrigliolo, Francesco; Benedetti, Anna.
Composting of wastes from citrus industrial processing (pastazzo and sludge) was studied in order to evaluate the evolution of organic matter during the process and to individuate chemical and/or biochemical techniques able to set the stability of the final product. Composts from two open-air piles of different composition were sampled every month during the whole period of composting (5 months) and the organic matter of each sample was characterised by chemical and biochemical techniques. Humification rate (HR%) and humification index (HI) were determined. Extracted organic matter of six samples collected for each compost was investigated by isoelectric-focusing technique (IEF). The biochemical analysis was based on the study of C-mineralisation after the...

Vulnerability in Agriculture
Provedor de dados: 21
Autores: Znaor, Darko.
The impact from climate change on agriculture is expected to be significant because of the vulnerability of agriculture to climate conditions in general. Precipitation, temperature, weather extremes and evaporation rates all impact production. Agriculture is important to the economy of Croatia due to its overall value and its impact on food security, vulnerable populations, and the employment it generates. In 2001, 92% of Croatia was classified as rural and 48% of the Croatian population lived in rural areas. Generally, rural households are more vulnerable due to poorer access to basic infrastructure and poorer housing conditions than households in urban areas.     Existing climate variability already has a significant impact on agriculture. Extreme...

Organic cash crop farms as net energy producers: Energy balances and environmental effects
Provedor de dados: 21
Autores: Halberg, Niels; Dalgaard, R.; Berntsen, J.; Olesen, J.E.; Dalgaard, T.
Organic farming (OF) principles include the idea of reducing dependence on fossil fuels, but little has been achieved on this objective so far in Danish OF. Energy use and greenhouse gas emissions from an average 39 ha cash crop farm were calculated and alternative crop rotations for bio-energy production were modelled. Growing rapeseed on 10% of the land could produce bio-diesel to replace 50-60% of the tractor diesel used on the farm. Increasing Grass-clover area to 20% of the land and using half of this yield for biogas production could change the cash crop farm to a net energy producer, reduce green house gas emissions and improve the nutrient management on the farm while reducing overall output of products only marginally.

Kalkingsforsøk med eggeskall - en utprøving i CYCLE-prosjektet
Provedor de dados: 21
Autores: Løes, Anne-Kristin; Øverland, John Ingar; Nordal, John.
Skallet av et egg veier ca. 8 gram, og inneholder verdifulle næringsstoffer. På Norturas fabrikk for foredling av egg, i Revetal i Vestfold, produseres det ca. 800 tonn med eggeskall hvert år. Noe av dette materialet ble knust og sammenliknet med vanlig jordbrukskalk i vekstsesongen 2014. Kalken i eggeskall hadde like god effekt som vanlig kalk til å øke pH i jorda, men ser ut til å være mye mer lett-tilgjengelig for næringsopptak i planter.

Klimabelastningen fra økologisk landbrug - hvad kan der gøres
Provedor de dados: 21
Autores: Olesen, Jørgen E.
Klimaændringer er uden tvivl en af de største udfordringer menneskeheden har stået over for. Det skyldes ikke mindst de enorme konsekvenser, som klimaændringerne vil have for verdens økosystemer og for vore levevilkår. I det politiske liv tales ofte om at undgå farlige klimaændringer. Hvad der er farligt er jo en politisk beslutning, hvorimod det er op til forskningen at fremlægge dokumentation for de konsekvenser forskellig grader af klimaændringer vil have. EU har defineret at det drejer sig om at undgå klimaændringer, der overstiger 2 grader i global middeltemperatur over førindustrielt niveau, og denne målsætning er på det seneste tiltrådt af G8 landene.

Organic farming without fossil fuels - life cycle assessment of two Swedish cases
Provedor de dados: 21
Autores: Sundberg, C.; Kimming, M.; Nordberg, Å.; Baky, A.; Hansson, P.-A.
Organic agriculture is dependent on fossil fuels, just like conventional agriculture, but this can be reduced by the use of on-farm biomass resources. The energy efficiency and environmental impacts of different alternatives can be assessed by life cycle assessment (LCA), which we have done in this project. Swedish organic milk production can become self-sufficient in energy by using renewable sources available on the farm, with biogas from manure as the main energy source. Thereby greenhouse gas (GHG) emissions from the production system can be reduced, both by substituting fossil fuels and by reducing methane emissions from manure. The arable organic farm studied in the project could be self-sufficient in energy by using the residues available in the...

Rural-urban co-development - challenges to post-industrial society
Provedor de dados: 21
Autores: Ingemann, Jan Holm.
The World Commission (1987) pointed out that sustainable development in general is a  prerequisite to alleviate fatal threats to human future. In this note1 it is stated that it is necessary to return to basic concepts and reflections to ensure that the aim, means, and context are remembered when radical changes to gain sustainability are designed. In particular this is the case when humanity’s social interplay (i.e., technology) with natural life support systems is in focus. Thus, the note is founded on a restatement of basics linked to the essential challenge facing post-industrial societies. In that light it is revealed that the current reactions to the challenge are insufficient because sustainability implies radical rather than marginal changes and...

Measuring degradation of transgenic DNA and screening for horizontal gene transfer from GMO-plant material during composting
Provedor de dados: 21
Autores: Magid, Jakob; Rasmussen, Lasse Dam; Moeller, Jacob.
The experiments show that composting of GM plant residues greatly increases the rate of degradation of transgenic DNA compared to the rate for plant residues left in the soil. If the persistence of transgenic DNA in the environments is considered as the only risk factor, composting is a 'DNA-safe' method to treat GM plant residues. However, even though transgenic plant DNA was not detected in bacterial isolates in our experiments, we cannot conclude that horizontal gene transfer can not take place. The 300 isolates tested proved to be too low a number to be conclusive. The numbers of isolates tested were based on the screenings indicating high transfer, but the screenings were biased apparently because some Bacillus species gave PCR products matching the...

Agroecological symbiosis (AES) enhances productivity in agriculture. A case study of the first AES in Finland indicated that productivity of on the organic crop farm could be increased by producing biogas from green manure leys, fallows, and other locally available biomasses. At the same time, the farm became a net-energy producer instead of being an energy consumer. Combining the food processing, crop production, energy production and closer interaction with consumers increase the overall sustainability of the local food system

Hvor meget kan biobrændsstoffer til transport nedbringe CO2-udledningen?
Provedor de dados: 21
Autores: Hauggaard-Nielsen, Henrik.
Indenfor en kortere tidshorisont vurderes der primært at være to muligheder for at nedbringe CO2-udledningen i fra transportsektoren: Den første er at reducere forbruget af transportbrændstoffer ved enten at udskifte de nuværende transportmidler til nogle med et mindre brændstofforbrug, eller ved at begrænse transporten ved fx at lægge større afgifter på brændstofferne. Det er i den forbindelse vigtigt at pointere, at væksten i transportsektoren anses som et naturligt produkt af den øvrige samfundsudvikling, herunder globalisering og øget handel på tværs af landsgrænser/verdensdele. Det betyder, at en reduceret vækst kan få betydning for den generelle samfundsøkonomi.  Den anden mulighed for at nedbringe CO2-udledningen i transportsektoren er at supplere...

Bioenergi betragtes som en af de bedste muligheder for på kort sigt at substituere fossile brændsler og reducere udledning af de menneskeskabte drivhusgasser. Det forventes, at landbrugssektoren vil komme til at spille en stadig større rolle for forsyning af samfundets med biomasseressourcer til disse formål. Biobrændstoffer, fremstillet ud fra hele eller dele af diverse landbrugsafgrøder og -biprodukter kan være direkte erstatningsprodukter for transportsektorens nuværende forbrug af fossile brændstoffer. Priserne på konventionelle fossile brændstoffer (f.eks. benzin og dieselolie) er op til tredoblet inden for de seneste 4 år. Forsyningssikkerheden med hensyn til brændstoffer spiller også en stadig større rolle i europæisk og international politik....

Strategic management of nitrogen within an organic cropping system using digestate from biogas production of recirculated crop residues
Provedor de dados: 21
Autores: Råberg, T.; Kreuger, E.; Björnsson, L.; Jensen, E.S.
This project investigates strategic management of nitrogen by integrating crop residue management with biogas production. The approach offers potential for diversified farmer income, as food crops, feedstock for biogas and digestate for nutrient cycling are produced simultaneously. This type of diversification provides multifunctional solutions in organic farming, especially in production without access to animal manure. Biogas production from crop residues offers the possibility of reducing both emissions and leaching of nutrients to the surrounding ecosystems, as compared to the case where crop residue is incorporated into the soil for decomposition (Baggs et al. 2000; Velthof et al. 2002). This type of multifunctional cropping system provides solutions...

Provedor de dados: 21
Autores: Hansen, Martin N.; Birkmose, Torkild; Mortensen, Børge; Skaaning, Kent.
Risikoen for ammoniaktab under lagring er højere for bioforgasset og separeret gylle, men effektiv overdækning af gyllelagre begrænser effektivt tabet. Med et effektivt flydelag er tabet ens for behandlet og ubehandlet gylle. Bioforgasning og separering af gylle begrænser ammoniaktabet i forbindelse med gyllens udbringning, effekten er højst af separering. Bioforgasning og separering af gylle fører ikke til mærkbar begrænsning af lugtgener fra gyllelagre, lugtgenerne kan dog effektivt begrænses ved effektiv overdækning af lagre.

During the last years the demand and use of Life Cycle Assessment (LCA) for calculating and comparing the ecological impacts of agricultural products has increased. However, within LCA important environmental impacts of agriculture, for instance biodiversity, soil quality or animal welfare are considered inadequately or stay unaccounted. In the case of biodiversity agriculture is considered as the main driver for the worldwide biodiversity loss. Thus, biodiversity cannot be neglected in future agricultural LCAs. Even though there is no widely accepted approach yet, a lot of research has been undertaken to solve the question how biodiversity can be assessed in the LCA framework.

EVALUATION OF DIFFERENT BIOLOGICAL WASTE TREATMENT STRATEGIES
Provedor de dados: 21
Autores: Reeh, U.; Møller, J.
Biological treatment of organic waste by aerobic composting and anaerobic digestion (biogas production) was compared with respect to a number of environmental effects and sustainability criterias including energy balance, nutrient recycling, global warming mitigation potential, emission of xenobiotic compounds and economy. The parameters were assessed based on case studies in the literature as well as our own research. Assessment of energy balance, nutrient recycling and global warming came out in favour of biogas production, but especially the results regarding estimation of global warming mitigation differ according to the assumptions made. Our calculations showed that a fugitive loss of approx. 14% of the biogas produced by anaerobic digestion will turn...

Codigestion of manure and organic waste at centralized biogas plants: Process imbalances and limitations
Provedor de dados: 21
Autores: Nielsen, Henrik Bangsø; Angelidaki, Irini.
The present study focuses on process inhibitions in Danish centralized biogas plants. Collection of data from the plants and a number of interviews showed that inhibitions occur frequently. High concentrations of ammonia, long chain fatty acids or other inhibitory compounds, and foaming in prestorage tanks are well known causes of inhibition. These problems mainly occurs due to: 1) inadequate knowledge about the waste composition and 2) its degradation characteristics, 3) inadequate process surveillance especially with regard to volatile fatty acids and 4) insufficient pre-storage capacity causing inexpedient mixing of the different waste products in the pre-storage tanks.

Sustainable pig nutrition in organic farming: By-products from food processing as a feed resource
Provedor de dados: 21
Autores: Wlcek, Sonja; Zollitsch, Werner.
Since keeping nutrient cycles intact is one of the most important goals in organic farming, the option of recycling by-products from organic food processing by feeding them to organically raised pigs was analyzed in this study. A more specific objective was to estimate the potential of this nutrient source in reducing the protein deficiency in organic pig nutrition. Sector-specific questionnaires were sent to 321 processors of organic foods in Austria. The information provided was used to estimate the total quantity available of the respective by-products. Proximate analysis, amino acid and mineral analysis were performed for different by-products. These data were combined with the available quantities of the respective by-products, resulting in the...

Effects of struvite application on soil and  plants: a short‐term field study
Provedor de dados: 21
Autores: Rittl, Tatiana; Krogstad, Tore; Eikås, Sondre; Saltnes, Torgeir; Sørensen, Gjermund; Glestad, Hans Emil; Løes, Anne-Kristin.
The soil P concentration commonly declines over time by organic management, if the farm does not acquire enough fertilisers or other inputs containing P from outside. An interesting source to supply farms with P is struvite (magnesium‐ammonium phosphate). This mineral easily precipitates when the concentrations of these nutrients is high enough, such as in a toilet separating urine. Struvite  may be produced in a wastewater treatment plant, as a method to reduce the P concentration in the water reaching the recipient. If struvite is allowed as a mineral fertiliser in the general fertiliser regulation of the European Union,which is currently under revision, this mineral may be allowed also in certified organic agriculture. A wastewater treatment plant in...

In two agricultural systems with and without animal husbandry the potential to produce renewable energy by digesting slurry and organic residues to biogas were assessed. In comparison to some other methods of energy production by biomass biogas production has the advantage of keeping the nutrients of the substrates within the agricultural system. They can be used as fertilisers.  In the investigated system with milk production (0,8 cows ha-1, 8 crops, among them 4 cereals, peas, potatoes and 2 clover grasses with catch crops after winter cereals and peas (see DEUKER et al. 2005), it is possible not only to ferment slurry, but also catch crops and straw of peas and cereals.

Vulnerability of Water Resources
Provedor de dados: 21
Autores: Znaor, Darko.
Water is a critical natural resource. It is used for drinking water, agriculture, wetlands services, and the production of hydroelectric energy, amongst others. Croatian fresh-water resources are abundant - indeed they are among the richest in Europe. Therefore, water resources are not considered a limiting factor for development in Croatia.  However, while there is no shortage of water per se for use in Croatia, problems do exist.  - First, a large amount of pumped water is wasted, which leads to lost revenue of up to EUR 286 million (0.9% of GDP) per year and increased GHG emissions resulting from the additional use of electricity for pumping.  - Second, farmers often face water shortages at certain critical times of the year’s growing season and, in...

Legumes for mitigation of climate change and the provision of feedstock for biofuels and biorefineries. A review
Provedor de dados: 21
Autores: Jensen, Erik S.; Peoples, Mark B.; Boddey, Robert M.; Gresshoff, Peter M.; Hauggaard-Nielsen, Henrik; Alves, Bruno J.R.; Morrison, Malcolm J.
Legumes are unique plants which contribute with several functions and services of great value for agriculture and society. Including legume food, forage and tree crops in farming systems is one approach to mitigate climate change. We have shown that the ability of the legumes to fix there own N via the symbiosis with rhizobia will reduce CO2 and N2O emissions compared to crops fertilized with industrial N. There is, however, a requirement to better understand the potential residual effects of legumes on N2O emissions. We have similarly shown that legumes have a key role in soilC sequestration and that the inclusion of legumes as sole crops, cover crops or intercrops usually enhances the rate of soil C accumulation even within relative short time periods....

Autores: Landau, Seth; Znaor, Darko.
In order to avoid dangerous climate change resulting from an increase in temperature of over 2oC, global GHG emissions must be cut by 50-85% by 2050. Croatia’s trajectory for emissions growth in the Business as Usual (BAU) case is estimated to result in 42 million tonnes of CO2e in 2020 – a significant increase from today. The EU has committed to reducing emissions by 20% by 2020. Croatia has committed to reducing emissions by an average of 5% for the period 2008-2012 from a baseline level of 36 million tonnes under the Kyoto Protocol. Croatia will also share at least part of the EU commitment for 2020, especially with respect to emissions from major point sources such as power plants and industrial sources.

Autores: Thomsen, MH; Tajoacha, N; Wu, C; Hovgaard, S; Houmøller, LP; Holm-Nielsen, JB; Thomsen, AB.
The most well-known way to produce bioethanol is by the enzymatic hydrolysis and fermentation of starch. In a new project “BioConcens” (2007) sponsored by DARCOF (DAnish Research Center for Organic Food and farming) one aim is to  develop a combined ethanol and biogas production for use in organic farming using starch containing biomass. Natural enzymes from cereals will be used for hydrolysis of starch to glucose in accordance with technology in brewing technology. Commercial enzymes are often produced from gene-modified organisms and will therefore not be used in the suggested organic context or process.

Small-scale organic agriculture, with integrated crop and animal production has the potential of producing significant amounts of food. Self-sufficiency of fuel for farm work has been investigated closer in this study, based on a set of prerequisites that were identified as important for future sustainability. An implication of the study is that low-tech solutions are more likely to be renewable in the production. Fuel production for farm work at the farm also facilitates nutrient recycling. Draught horse power turned out to be comparable with other biofuels, and in a system perspective even more efficient in some cases. For ensuring a sustained food production social solutions for cleaning and recycling human excreta must be developed. Low-input...

Elemental composition and phosphorus availability in hydrochars from seaweed and organic waste digestate
Provedor de dados: 21
Autores: Løes, Anne-Kristin; Sandquist, Judit; Meyer, Gregor.
By hydrothermal liquefaction (HTL) of organic matter, hydrochars are produced which may be applied to soil for carbon sequestration. From substrates of wild seaweed and organic waste digestate, we measured the distribution of solids (hydrochars) and liquids after HTL at 150 and  200°C, 50 bar for 1 h. The output of liquids and solids was recorded. Elemental analysis was conducted for essential plant nutrients, potentially toxic elements (PTEs) and silicon in the hydrochars. Sequential extraction of phosphorous (P) was conducted to assess the P availability  for plants. About 20% of the initial dry matter dissolved during HTL of digestate, and 55% for seaweed. More dry matter was dissolved by increased temperature. Except from arsenic in seaweed chars, the...

Hard and soft science issues to be negotiated to improve urban metabolism

In the industrialised world, waste management systems have developed to maturity without primary concern for recycling. These systems have originally been designed to ensure human health and a high local hygienic standard. More recently environmental concerns have been the driving force behind a technological development of sewage treatment with biological removal of N, P and organic matter. This technology addresses some immediate problems in the aquatic environment, but the sewage sludge from the treatment plants contains considerable quantities of xenobiotic compounds and heavy metals, and only a fraction of the nutrients that entered the urban areas, thus making the sludge a non-attractive fertiliser source. In recent years there has been concern about...

REDUCTION OF FAECAL MICROBIOLOGICAL INDICATORS IN DIFFERENT COMPOST TOILETS
Provedor de dados: 21
Autores: Møller, J.; Forslund, A.; Dalsgaard, A.
Large variations in numbers of faecal indicator bacteria were found irrespective of the storage time of collected human faeces. Little heat seemed generated from composting processes when bin units were stored locally in households. The low reduction in microbiological parameters and very limited temperature increase were generally corroborated by the results obtained in experiment 2 when pathogen indicators were added to thoroughly mixed faecal matter. Even though Salmonella died of rapidly the other faecal bacterial indicators survived in large numbers. We conclude, that the collection and storage of human faeces in the closed plastic bins studied here is associated with only little temperature increase and subsequent reduction in faecal bacterial...

There are several levels of analysis, where different external aspects are added in each level, e.g. externalities such as savings in CO2-emissions by replacing fossil fuels. The competition between use of land for bioenergy or for food is evaluated.

Eco-efficiency and agricultural innovation systems in developing countries: Evidence from macro-level analysis
Provedor de dados: 21
Autores: Grovermann, Christian; Wossen, Tesfamicheal; Müller, Adrian; Nichterlein, Karin.
Agricultural innovation is an essential component in the transition to more sustainable and resilient farming systems across the world. Innovations generally emerge from collective intelligence and action, but innovation systems are often poorly understood. This study explores the properties of innovation systems and their contribution to increased eco-efficiency in agriculture. Using aggregate data and econometric methods, the eco-efficiency of 79 countries was computed and a range of factors relating to research, extension, business and policy was examined. Despite data limitations, the analysis produced some interesting insights. For instance public research spending has a positive significant effect for emerging economies, while no statistically...

Biomass energy in organic farming - the potential role of short rotattion coppice
Provedor de dados: 21
Autores: Jørgensen, Uffe; Dalgaard, Tommy; Kristensen, Erik Steen.
One of the aims of organic farming is to “reduce the use of non-renewable resources (e.g. fossil fuels) to a minimum”. So far, however, only very little progress has been made to introduce renewable energy in organic farming. This paper presents energy balances of Danish organic farming compared with energy balances of conventional farming. In general, the conversion to organic farming leads to a lower energy use (approximately 10% per unit of product). But the production of energy in organic farming is very low compared with the extensive utilisation of straw from conventional farming in Denmark (energy content of straw used for energy production was equivalent to 18% of total energy input in Danish agriculture in 1996).    Biomass is a key energy carrier...

Replacement of fish meal with a matrix of organic plant  proteins in organic trout (Oncorhynchus mykiss) feed, and the effects on nutrient utilization and fish performance
Provedor de dados: 21
Autores: Lund, Ivar; Holm, Jørgen; Rasmussen, Hanne T.; Dalsgaard, Anne Johanne; Jokumsen, Alfred.
This study examined the effects on nutrient utilization and fish performance when replacing 16, 31, and 47% of fish meal protein (corresponding to replacing 15, 29 and 44%, respectively, of total dietary protein) with a fixed matrix of organic pea, horsebean and rapeseed plant protein concentrates (PPC) in a ratio of 1.07:1.00:0.66. Four iso-energetic and iso-nitrogenous diets were produced to include 0, 136, 274 or 410 g kg-1 of the organic PPC matrix, respectively. The organic protein ingredients were chosen based on their high protein content, and the matrix was established to mirror the amino acid composition of fish meal. The plant ingredients were dried, dehulled, grinded and air classified in accordance with the European Union Commission Regulation...

Legumes for mitigation of climate change and feedstock in a bio-based economy - a review
Provedor de dados: 21
Autores: Jensen, Erik S.; Peoples, Mark B.; Boddey, Robert M.; Gresshoff, Peter M.; Hauggaard-Nielsen, Henrik; Alves, Bruno J.R.; Morrison, Malcolm J.
Legumes are unique plants which contribute with several functions and services of great value for agriculture and society. Including legume food, forage and tree crops in farming systems is one approach to mitigate climate change. We have shown that the ability of the legumes to fix there own N via the symbiosis with rhizobia will reduce CO2 and N2O emissions compared to crops fertilized with industrial N. There is, however, a requirement to better understand the potential residual effects of legumes on N2O emissions. We have similarly shown that legumes have a key role in soilC sequestration and that the inclusion of legumes as sole crops, cover crops or intercrops usually enhances the rate of soil C accumulation even within relative short time periods....

Som resultat af projekterne kan drages følgende hovedkonklusioner om kompostering af fæces fra mennesker: Fæces fra de undersøgte typer af kompostbeholdere bør ikke anvendes til jordbrugsformål uden viderebehandling, da dette skønnes at være behæftet med hygiejne- og sundhedsrisici. Det skyldes, at der ikke blev dokumenteret egentlige termofile temperaturstigninger i fæcesmaterialet i komposttoiletenhederne i Hjortshøj, Dyssekilde og Sverige, og at fækale indikatorbakteriers antal varierede voldsomt, og der ingen entydig tendens var til forekomst af lavere kimtal ved lange opbevaringstider af de opsamlede fækalier.

Sustainability, overall and process efficiency of energy crops
Provedor de dados: 21
Autores: Schäfer, Winfried.
A method to calculate efficiency of energy crop production including sun energy,  direct and indirect energy for cultivation, processing, and conversion into fuel is  demonstrated using rape and derived fuels as an example. Every production and  conversion step is a process and calculated separately. The overall efficiency  includes energy input and output of all processes. The process efficiency of rape  cultivation reaches in Finland up to 1100 %. However, the overall energy efficiency of  rape methyl ester (RME) is 1 to 2 ‰ only. The production of biogas from manure of  dairy fed by rape meal results in a process energy efficiency of 33 to 41 %, but the  overall energy efficiency of RME and biogas together is only 1.2 to 2.5 ‰. In  contrast, thermal or...

Enhancing Sustainability by Landscape-Design and Conversion to Organic Agriculture
Provedor de dados: 21
Autores: Kainz, Maximilian.
A hilly site with variable soils and facing all the problems of modern agriculture was re-designed and converted to organic agriculture in 1992. After 10 years of measurements and observations it was determined that soil compaction, runoff, and erosion were reduced, quality of groundwater and ponds was gradually enhanced, diversity of wildlife was enriched, and the economic situation of the farmer was improved. Besides landscape design, conversion to organic agriculture is regarded as a key instrument towards sustainable land use in this region.

Sustainable Intensification of Tropical Agro-Ecosystems: Need and Potentials
Provedor de dados: 21
Autores: Andres, Christian; Bhullar, Gurbir S.
Rapid population growth, increasingly complex economies and novel industrial uses of agricultural products call for further intensification of agriculture, particularly in the tropics. How to achieve sustainable intensification of food production systems in tropical regions that are challenged by ongoing climate change, loss of natural resources and biodiversity is a matter of debate. Here we highlight the major knowledge gaps in agricultural research and policy that must be addressed to develop adequate governance and regulatory frameworks for sustainable agricultural intensification. They include quantification of the (i) value of (public/private) goods generated by ecosystem services, (ii) costs to conserve the natural resources and biodiversity that...

LATRINE COMPOSTING – A HYGIENIC EVALUATION

Thermophilic composting of faecal matter from urine diverting toilets can effectively reduce the numbers of faecal bacterial indicators and pathogen. Already at 50C, the numbers of pathogens, including the Salmonella phage, and indicator organisms analysed were effectively reduced within a few days of exposure. Although the numbers of enterococci were reduced, they were continuous isolated as purple colonies on Slanetz and Bartleys agar after prolonged exposure at all temperature levels studied. This indicates that certain micro-organisms present in the composted faecal material, Enterococcus spp. or micro-organisms resembling enterococci on the agar medium, can survive and multiply even at 60C. These findings question the use of enterococci as faecal...

Autores: Sodjinou, Epiphane; Glin, Laurent C.; Nicolay, Gian L.; Tovignan, Silvère; Hinvi, Jonas.
Organic cotton relies on ecological processes and the use of natural resources to sustain the production system, unlike conventional cotton, mainly characterized by massive utilization of synthesis chemicals. In West Africa, where rural livelihoods are particularly vulnerable, organic cotton is expected to contribute not only to poverty reduction but also to strengthen households’ resilience.  The objective of this study was to assess institutional and socioeconomic factors determining farmers’ decisions to adopt organic cotton. For this purpose, we applied a probit model on empirical data collected from producers of the Centre and the Northern parts of Benin. Overall, we found that organic cotton adoption is mainly determined by farmers’ socioeconomic...

The majority of innovations pioneered within/for the organic olive oil production (OOOP) chain may, and are, increasingly becoming, adopted by the conventional olive oil production chain, especially regarding cultivation, inputs related to plant/ecosystem protection and trade/promotion of specialized high quality products. Therefore the OOOP-chain may become a pioneering paradigm, for the implementation and convergence of agricultural production, marketing, sustainable rural development and environmental/biodiversity protection EU policies in the Mediterranean. Moreover, it appears that OOOP systems are increasingly becoming model systems for developing, applying and evaluating innovations that may have far more general applicability for Mediterranean...

Abstract: The objective of this work was to evaluate the reuse of sucrose syrup in pineapple (Ananas comosus) osmotic dehydration and the application of the spent solution in fruit dragée formulation. Osmotic dehydration trials were performed in five cycles (65° Brix/45°C/3 hours), directly reusing the osmotic solution, with only one intermediate reconditioning step. Variations in osmotic solution properties and in dehydration parameters were observed, as well as a low microbial load in the system. The spent solution was rich in vitamin C (30 mg 100 g-1). Pineapple dragée covered with red fruits and acai powders were obtained with the reconditioned spent solution used as an adhesion solution. The dragée presented high levels of vitamin C (176 mg 100 g-1),...

The Determinants of the Municipality's Decision to Implement Recycling in Japan: Socio-Economic and Technological Factors
Provedor de dados: 31
Autores: Usui,   Takehiro; Chikasada,   Mitsuko.
The Japanese government has encouraged reduction, reuse, and recycling of waste with the slogan "3R" under the Basic Law for Establishing a Recycling-based Society. However, the law is non-binding in nature; thus, the collection of each type of recyclable containers and packaging is done at the discretion of the municipalities. Some municipalities do not provide collection services for these recyclables.  Why do some municipalities recycle while others do not? Few studies have investigated the determinants of the municipality's decision to collect recyclables. The purpose of this study is to examine the factors affecting a municipality's decision to implement the collection of already sorted recyclable containers and packaging in Japan.

Extended Product Responsibility: An Economic Assessment of Alternative Policies
Provedor de dados: 31
Autores: Palmer,   Karen L.; Walls,   Margaret.
Extended Product Responsibility embodies the notion that agents along a product chain should share responsibility for the life-cycle environmental impacts of the product, including those associated with ultimate disposal. Extended Producer Responsibility is a narrower concept which places responsibility on producers and focuses primarily on post-consumer waste disposal. Manufacturer "take-back" requirements are the policy lever most often associated with Extended Producer Responsibility. In this paper, we discuss alternative incentive-based policies that are consistent with the objectives of Extended Product and Producer Responsibility. We argue that an upstream combined product tax and recycling subsidy (UCTS) is generally more cost-effective and imposes...

RECYCLING, INTERNATIONAL TRADE, AND THE DISTRIBUTION OF POLLUTION: THE EFFECT OF INCREASED U.S. PAPER RECYCLING ON U.S. IMPORT DEMAND FOR CANADIAN PAPER
Provedor de dados: 31
Autores: Michael,   Jeffrey A.
The quantity of paper recycled in the U.S. has more than doubled since 1985.  International trade theory predicts that this will lead to reduced imports of paper, and a shift in domestic production toward waste paper intensive outputs (e.g., newsprint) and away from higher grade products such as printing/writing paper.  Import demand elasticities with respect to input prices were estimated for newsprint, printing/writing, and all paper utilizing 20 years of monthly data.  The empirical results confirm the predictions of theory, and illustrate a channel through which recycling may be more beneficial for U.S. industry than the domestic environment.

Autores: Jenkins,   Robin R.; Martinez,   Salvador A.; Palmer,   Karen L.; Podolsky,   Michael J.
This paper examines the impact of two popular solid waste programs on the percent recycled of several different materials found in the residential solid waste stream. We examine a unique, national, household-level data set containing information on the percent recycled of five different materials: glass bottles, plastic bottles, aluminum, newspaper, and yard waste. We find that access to curbside recycling has a significant and substantial positive effect on the percentage recycled of all five materials and that the level of this effect varies across different materials. The length of the recycling program's life has a significant and positive effect on two of the five materials and a mandatory recycling requirement does not affect any materials. The level...

A Flexible Inventory Model for MSW Recycling
Provedor de dados: 31
Autores: Louis,   Garrick; Shih,   Jhih-Shyang.
Most of the United States have laws mandating the recycling of municipal solid waste (MSW). In order to comply, municipalities recycle quotas of materials, without regard to fluctuating prices. An inventory system is proposed that allows municipalities to be sensitive to materials prices as they recycle in accordance with state mandates. A dynamic model is developed; it uses historical secondary material prices as exogenous inputs to minimize the net present value of MSW recycling system cost. The model provides a cost-effective method for municipalities to achieve their MSW recycling targets. The savings is approximately $1.43 per ton of MSW generated based on total MSW management costs of $13.5 per ton. The model also allows one to investigate the...

How Local Governments Structure Contracts with Private Firms: Economic Theory and Evidence on Solid Waste and Recycling Contracts
Provedor de dados: 31
Autores: Walls,   Margaret.
Solid waste management services are contracted out to private firms in many U.S. communities. Household waste collection, transport, and disposal are relatively straightforward services to define within the terms of a contract. The addition of recycling, however, significantly complicates matters. How should contracts be structured to provide incentives for recycling? Who should own key facilities, such as recyclable materials processing facilities? Should a separate contract for processing and sale of materials be used, or should these services be provided by government employees or purely private markets? These questions are addressed in this study using the principal-agent framework and the theory of incomplete contracts in economics. I explain stylized...

The Role of Economics in Extended Producer Responsibility: Making Policy Choices and Setting Policy Goals
Provedor de dados: 31
Autores: Walls,   Margaret.
Extended producer responsibility (EPR) embodies the notion that producers should be made physically or financially responsible for the environmental impacts their products have at the end of product life. The EPR concept has taken hold in Europe and is garnering wide interest in the United States, where a variant known as "shared product responsibility" or "product stewardship" is usually the preferred approach. There are several policy instruments that are consistent with EPR-product take-back mandates, advance disposal fees, deposit-refunds, recycled content standards, and more. The EPR concept itself, however, provides little guidance about which of these instruments might be appropriate under particular conditions and for particular products. Moreover,...

More water for everything? The problem of bogus water savings in northern Victoria, Australia
Provedor de dados: 31
Autores: Gyles,   Oliver.
The Victorian Department of Sustainability and Environment (DSE) spent the latter decades of the 20th century fully integrating the surface and sub-surface drainage systems with the water distribution network in northern Victoria, thereby enabling complete recycling of outfalls, leaks and seepage from its channels. Yet in 2007, in repudiation of this recycling capacity, DSE announced a multibillion dollar modernisation project it claims will “create” 450 GL of “new water” by reducing “inefficiencies” in the channel distribution system. Examination of the northern Victorian irrigation supply system shows it was fully integrated with more than adequate recycling capacity before the project began. In a classic case of double counting, DSE was already...

Sequencing Renewables: Groundwater, Recycled Water, and Desalination
Provedor de dados: 31
Autores: Roumasset,   James A.; Wada,   Christopher.
Optimal recycling of minerals can be thought of as an integral part of the theory of the mine. In this paper, we consider the role that wastewater recycling plays in the optimal extraction of groundwater, a renewable resource.  We develop a two-sector dynamic optimization model to solve for the optimal trajectories of groundwater extraction and water recycling. For the case of spatially increasing recycling costs, recycled water serves as a supplemental resource in transition to the steady state. For constant unit recycling cost, recycled wastewater is eventually used as a sector-specific backstop for agricultural users, while desalination supplements household groundwater in the steady state. In both cases, recycling water increases welfare by shifting...

Use of un-treated/partially treated wastewater for irrigation in the dry countries of Asia and Africa and recycling of treated wastewater in the water scarce developed countries has become a common practice due to various reasons. While the lack of wastewater treatment to appropriate levels before use is a major problem in developing countries, the high cost of wastewater recycling is the major problem in developed countries. The current paper is part of a doctoral research and presents the conceptual framework for the research and the methodology that can be used to tackle the problems associated with wastewater recycling.

Economics of Wastewater Treatment and Recycling: An Investigation of Conceptual Issues
Provedor de dados: 31
Autores: Devi,   Mekala Gayathri; Davidson,   Brian; Boland,   Anne-Maree.
In the context of continuous droughts, the search for alternative water sources and increasing environmental restrictions on discharge of treated wastewater into natural water bodies, treated wastewater recycling offers a potential solution. In this paper the methods needed to assess the questions - to what extent treated wastewater can complement the existing water sources in different sectors and at what cost - are discussed? It was concluded that a comparative Benefit Cost Analysis of different combinations of uses and treatment levels would be a critical component in the development of a decision support tool which could be used by urban planners and water authorities. It was also found that community acceptance of recycled water, distribution of costs...

Nutrient leaching potential following application of papermill lime-sludge to an acidic clay soil
Provedor de dados: 90
Autores: Vettorazzo,S. C.; Amaral,F. C. S.; Chitolina,J. C.
This experiment was carried out under greenhouse conditions with soil pots during 210 days, to evaluate the effect of calcitic papermill lime-sludge application (at the rates 0, 773, 1.547, and 2.320 mg kg-1 or respective equivalents to control, 2, 4, and 6 t ha-1), on chemical composition of soil leachate and its effects on eucalypt growth and yield. Highest soil leachate pH, SO4, and Na concentrations occurred in the 4 and 6 t ha-1 treatments. Soil leachate nitrate concentrations decreased with increasing lime-sludge rate. Soil leachate phosphate remained low (below the detection limit) in all treatments until 120 days, while the concentration increased in the lime-sludge treatments at 210 days (last sampling) in about 600 mg L-1. Lime-sludge decreased...

Autores: Souza,Priscila F. de; Grazziotti,Danielle C. F. S.; Grazziotti,Paulo H.; Fernandes,Luiz A.; Silva,Enilson de B.; Gandini,Andrezza M. M.
ABSTRACTBiodegradation techniques may help contaminated organic wastes to become useful for plant production. The current study aimed to evaluate the efficiency of composting in the biodegradation of toxic residues from the textile industry and its use as substrate in saplings production. Cotton cloths contaminated with oil and grease, used in loom maintenance, were composted in a mixture with cattle manure. The composted material replaced coconut fiber in the substrate for the production of eucalyptus rooted cuttings: mixture of vermiculite, carbonized rice husk and coconut fiber in the ratio of 2:1:1 (v/v) and using it as control. Thus, the amount of rice husks remained unchanged and the amount of vermiculite and compost varied. The compost proportion in...

Autores: Espíndola Filho, Antonio; Oetterer, Marília; Assis, Alair.
The objective of this study was to create new products using fish residues as well as to reduce environmental pollution, thus preventing the waste of nutrients, reduction of costs involved in the animal feed production chain and in organic agriculture, to be indirectly used as human food. With added value and increased food safety, these new products can be used as supplements for traditional fish meals, resulting in an immediate reduction in the importation of this ingredient essential for agribusiness. Results showed that the resulting organic meals have low production cost and high biological value regarding essential amino acids, fatty acids, minerals and vitamins, providing an alternative to solve the environment problem related to fish residues.

Current trial evaluated yield, organic matter and mineral composition of the residual harvest of five maize hybrids at three cutting heights (15, 35 and 55 cm). The experimental design consisted of a randomized block split plot with three replications. Concentrations of N, P, K, Ca, MS, MM and MO in the samples were evaluated. No difference among hybrids occurred in stem diameter (22.4 mm), ear production (8.0 ton DM ha-1), grain harvest index (37.3%) and total forage yield (15.0 ton DM ha-1). Hybrid effect occurred for variables of mineral composition of harvest residues. With the exception of calcium, a rise in cutting height from 15 to 55 cm failed to increase the concentration of minerals in the residue. The amount of organic matter and mineral...

In wild animals, containment is the moment of greatest stress caused by the investigator to the animal due to its natural resistance to the moment of capture, handling, containment and transport, attitudes frankly contrary to his nature. In birds, the restraint must meet certain criteria in order to control the animal's movements, avoiding trauma at the same time that you need to keep your breathing amplitude. The high risk of death during the restraint of these animals raised the need to design a device, from bottles of poly ethylene terephthalate (PET), for containing parrots-browed Amazon (Amazona rhodocorytha), a parrot endemic to the Atlantic Forest in southeastern Brazil, and endangered with extinction, which allowed the observation of respiration,...

Provedor de dados: 64
Autores: Dalpisol,Maristela; Serrat,Beatriz Monte; Motta,Antonio Carlos Vargas; Poggere,Giovana Clarice; Bittencourt,Simone; Barbosa,Julierme Zimmer.
ABSTRACT In Paraná, most of the sludge generated in sewage treatment plants is subjected to the prolonged alkaline stabilization process. Although it is known that the alkaline sewage sludge contains micronutrients such as Zn, Cu and Mn, little is known about the availability of these elements in soils treated with this type of sewage sludge. Thus, the objective of the study was to evaluate the influence of alkaline sewage sludge from Paraná on Zn, Cu and Mn availability in soils. Twenty sewage treatment plants were selected throughout Paraná, where alkaline sewage sludge and the most representative agricultural soil of the each region were collected. Each soil was incubated for 60 days with alkaline sewage sludge rates (0, 10, 20, 40, and 80 Mg ha-1) from...
