: A bioüzemanyagok adózása Magyarországon AgEcon
Palyi, Zoltan.
Megállapítható, hogy a bioetanol adózási helyzete kedvezőbb, mint a biodízelé. Az etanol forgalma dinamikusan növekszik. Magyarországon jelenleg több mint 200 benzinkúton kapható E85 üzemanyag. Annak érdekében, hogy Magyarországon legalább 10% legyen a közlekedési szektorban a „bio” arány, célszerű első lépésként az üzemanyagokban lévő biokomponens-arányt a jelenlegi 4,8%-ról 6,0%-ra, majd 1-2 év múlva 8,0%-ra emelni. A biodízelnél, például a B40- ---------------------------------------------- Apparently the status of bioethanol in terms of taxation is more favourable than that of biodiesel. Ethanol sales are growing dynamically. The E85 fuel is currently sold at more than 200 petrol stations in Hungary. In order to increase the share of “bio” to at...

Agronomic and molecular characterization of wild germplasm Saccharum spontaneum for sugarcane and energycane breeding purposes Scientia Agricola
Silva,Jorge Alberto Gonçalves da; Costa,Paulo Mafra de Almeida; Marconi,Thiago Gibbin; Barreto,Everton Jean da Silva; Solís-Gracia,Nora; Park,Jon-Won; Glynn,Neil Charles.
ABSTRACT: Among the species related to sugarcane, Saccharum spontaneum (L.) is a wild species with the greatest potential as a source of genetic variation to cope with biomass production in harsh environments. Due to its high yield, early vigor, ratooning ability, low input requirements and tolerance to various biotic and abiotic stresses, sugarcane breeders have shown interest in its contribution, as a donor of genes, to the development of high biomass energy canes. The conservation, evaluation and utilization of the genetic variability of S. spontaneum available in germplasm collections are critical for breeding, but, given the aggressive rhizomatous growth habit and the ability to propagate via seed dispersal, S. spontaneum is classified as a noxious...

Air drying of macauba fruits: maintaining oil quality for biodiesel production Agronomy
Silva, Gutierres Nelson; Grossi, José Antônio Saraiva; Carvalho, Marcela Silva; Kuki, Kacilda Naomi; Goulart, Samuel de Melo; Pimentel, Leonardo Duarte.
Macauba fruits are oil-rich drupes with high moisture content at harvest. This feature can affect the chemical properties of the oil and increase the costs of biodiesel production. Therefore, it is necessary to adopt postharvest strategies to ensure oil quality. The aim of this work was to evaluate the effect of drying macauba fruit on the quality of the pulp oil. Husked and dehusked fruits were dried at 60°C and then stored. At 0, 15, 45, 100, and 180 days after storage, fruit samples were retrieved, and the oil from the pulp was evaluated for physicochemical parameters. The removal of the husk from the fruits considerably reduced the drying time compared to that of the husked fruits. Drying prevented deterioration of the fruit even after 180 days of...

An Illustrated Guide to Research Findings from USDA's Economic Research Service AgEcon
Economic Research Service.
This book contains a sampling of recent ERS research illustrating the breadth of the Agency’s research on current policy issues: from biofuels to food consumption to land conservation to patterns of trade for agricultural products. What you won’t find in this collection is any mention of economists’ favorite analytic tools (regression analyses, for example, and coefficients of variation). We wanted this guide to highlight results, not process. Even so, the findings on display here are all based on rigorous and robust application of such tools as well as use of the latest econometric techniques.

Bioenergy production in Finland and its effects on regional growth and employment AgEcon
Simola, Antti; Kinnunen, Jouko; Torma, Hannu; Kola, Jukka.
Finnish national climate and energy strategy sets the share of renewables in energy use to 38%, and a significant amount of this should be covered by biomass based energy. In 2020 forestry is set to contribute 24 TWh and agriculture 4-5 TWh to energy production. In particular, bioenergy resources are considerable in the rural areas. However, the regional aspects have gone without investigation before this study. This study is a general equilibrium analysis. We considered only the by-products and waste material from agriculture and forestry as the resources for bioenergy, and only heat and power production were considered as the potential end uses. A regional CGE-model (RegFinDynBio) was used to analyse the impact of increased use of bioenergy potential....

BIOHYDROGEN PRODUCTION IN AnSBBR IN FED-BATCH FROM STARCH EFFLUENT: INFLUENCE OF ORGANIC LOAD REA
Tonello,Tamiris U.; Andreani,Cristiane L.; Mari,Angelo G.; Fernandes,José R.; Gomes,Simone D..
ABSTRACT The hydrogen is a fuel with a high energy density. Studies have sought to verify the potential of different residues and configurations of reactors in the production of biohydrogen. This study evaluated the influence of the organic loading rate on the production of biohydrogen from cassava starch wastewater (CSW) in anaerobic sequencing batch biofilm reactors (AnSBBR) operated in a fed-batch. In the tests, the organic loading rates of 9.0; 13.5 and 18.0 gCT L−1 d−1 were used, at cycle times (CT) of 4; 4 and 2 h (tests I, II and III, respectively). The reactor was inoculated with sludge from a pilot anaerobic reactor used in the treatment of CSW, heat treated (heated at 90°C for 15 min). With the increase of the organic load (condition I to II)...
