| GMO moratoria are in place in Australia, in some states and not in others. Is co-existence possible between organic farming and GMO farming? And if so, under what circumstances? Australia has more certified organic land than any other country, with a reported 12.0 million hectares of certified organic land compared to the world total of 37.5 million hectares. In a recent court case, an organic farmer lost his organic certification because of GMO contamination. A total of 325 hectares of his 478 hectare farm were contaminated with GM canola blown from a neighbouring property, and this resulted in the decertification of most of the farm. The organic farmer sued his neighbour, a GMO farmer, on the basis of nuisance or negligence, he sought damages for loss of... |

| The addition of a biorefinery to an organic farm was investigated, where ethanol was produced from germinated rye grains and whey, and the effluent was separated into two streams: the protein-rich solid fraction, to be used as animal feed, and the liquid fraction, which can be co-digested with clover grass silage to produce biogas. A method for ethanol production from rye was applied by utilizing inherent amylase activity from germination of the seed. Biogas potential of ethanol fermentation effluent was measured through anaerobic digestion trials. The effluent from the trials was assumed to serve as natural fertilizer. A technoeconomic analysis was also performed; total capital investment was estimated to be approximately 4 M USD. Setting a methane... |

| The consumer demand for environmentally friendly, chemical free and healthy products, as well as concern regarding industrial agriculture’s effect on the environment has led to a significant growth of organic farming. On the other hand, organic farmers are becoming interested in direct on‐farm energy production which would lead them to independency from fossil fuels and decrease the greenhouse gas emissions from the farm. In the presented work, the idea of biogas and bioenergy production at the organic farm is investigated. This thesis is devoted to evaluate such a possibility, starting from the characterization of raw materials, through optimizing new processes and solutions and finally evaluating the whole on‐farm biorefinery concept with the help of a... |

| Effects of extrusion parameters and raw materials on extrudate expansion are respectively investigated in a twin-screw extruder and a single-screw extruder extrusion cooking experiments for fish feed, wheat, and oat & wheat mixture processing. A new phenomenological model is proposed to correlated extrudate bulk density, extrusion parameters and raw material changes based on the experimental results. The average absolute deviation (AAD) of the correlation is 2.2% for fish feed extrusion in the twin-screw extrusion process. For the single-screw extrusion process, the correlation AAD is respectively 3.03%, 5.14% for wheat and oat & wheat mixture extrusion; and the correlation AAD is 6.6% for raw material change effects. The correlation results... |

| This study presents a new approach to model the biophysical potentials for increased biomass harvest in Denmark, and a multi-criteria sustainability assessment of the socio-economic and environmental effects of different scenarios for such increased production and new biobased economy in rural landscapes. Thereby the results serve as input to the ongoing productivism – post-productivism debate related to rural spaces in Europe. Empirical results from a case study of large scale conversion to biorefenery technologies, aiming to increase the total Danish harvest of biomass by 10 million tonnes via the conversion to new types of crop production and land management, is used as an example, and will be related to the common conceptual model presented by the... |

| The objective of this research, was to quantify sustainability indicators of organic dairy farms using Automatic Milking Systems (AMS), and a comparative group of organic dairy farms using conventional milking systems (CMS). Milk yield per cow was higher for AMS farms but did not result in higher net return to management. Nitrogen surplus per ha of available land was higher for AMS farms, Animal health was unaffected by AMS use, as also most milk quality aspects; somatic cell count, clostridium spores and urea. Acid degree value (ADV), measured as free fatty acids (FFA) in the milk, was higher in milk from AMS users. Labour time was decreased by almost 50% for AMS users, to 2.3 min/cow/day. It could be concluded from quantification of selected indicators... |

| Ziel der technologischen Weiterentwicklung ist, agrartechnische Arbeitsprozesse durch den Einsatz von technischen Neuerungen zu vereinfachen, präziser auszuführen und/oder zu automatisieren. Ampferroboter: Die nichtchemische, mechanische Ampferbekämpfung im biologischen Landbau erfordert einen hohen Arbeitsaufwand und bedeutet eine starke körperliche Belastung. Für eine Automatisierung sind ansatzweise einzelne Elemente vorhanden, die in eine Weiterentwicklung einfliessen könnten. Der Automatisierungsgrad des gesamten Prozesses soll schrittweise erhöht werden, um die körperliche Belastung und den Arbeitszeitaufwand für die mechanische Ampferbekämpfung zu senken und die Erfolgsrate zu erhöhen. Automatisches Lenk- und Fahrsystem: Traktoren mit... |

| Organic agriculture is one sustainable alternative to avoid negative environmental effects often caused by conventional agriculture. The area for organic farming in Europe is increased rapidly in the last decades and Denmark is one of the top-ten countries in Europe as regards the organic share of the total cultivated area. The production of bioenergy from local biological resources and the maintenance of soil fertility seem to have been opposing aims in organic agriculture. In organic farming, there is a strong effort to reduce the reliance on fossil fuels and decrease greenhouse gas emissions in organic agriculture. Cheese whey is a by-product from the dairy industry, which has the highest market share of organic foods in Denmark. It generates... |

| Projektziel ist, anhand ausgewählter Proben (aus definierten Langzeitversuchen und Marktproben) eine vergleichende Bewertung von pflanzlichen Rohstoffen aus konventionellem und ökologischem Anbau vorzunehmen. Dafür soll die Gültigkeit der im Projekt 02OE170 (02OE170) validierten Methoden zur Unterscheidung ökologischer und konventioneller Lebensmittel auf weitere Produkte sowie Sorten-, Standort- und Jahrgangsvariationen ausgeweitet werden. Dies ist ein wichtiger Schritt zur Ermittlung der Praxistauglichkeit der Methoden. Für die Vergleichsmessungen der codierten Proben werden Kupferchlorid-Kristallisation und Fluoreszenz-Anregungsspektroskopie eingesetzt, außerdem wird der Physiologische Aminosäurestatus verglichen, die Gehalte an sekundären... |
