| 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... |

| 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... |

| 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... |

| ABSTRACT In Brazil, there are several crops producing oil for biofuel production, such as canola, sunflower, peanut, cotton, castor bean, soybean, among others. There are parameters that indicate the energetic and economic viability for the production of biofuels, and that can be applied, for example, in transgenic soybeans. The present study aimed to evaluate the energetic viability of Intacta RR2 PROTM soybean for biofuel production.Experiments were conducted in the municipalities of Palotina and Marechal Cândido Rondon, both in the State of Paraná. Energy balance calculations were carried out from the production system, estimating energy expenditure, including the agricultural and industrial stages. The inputs used were considered as input of energy,... |

| Bioenergy is a renewable source of primary energy and its sustainable use is an advantage to the current global energy crisis. The use of vegetable resources for energy purposes requires specific studies of the impacts that might occur to the economy and the environment. The province of Santa Fe (Argentina) has an agroproductive structure capable of providing biomass for its processing and production of energy. The objective of this work was to value the capacity of this province for bioenergy production from grains transformation into biofuels and the biomass energy from crop straw, and speculates on the impact on soils from removed crop residues. Crop residues of the ten most important grain and oilseed crops (15.2x10(6) Mg year-1) and bioethanol and... |

| 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)... |

| Biomass based energy production has attained a significant market share within the developing renewable energy market. In comparison to alternative renewable energy sources, biomass has several special features: it is not inexhaustible in the short term (limitation of arable land) and it is not only an energy source. Other usages like food or feed compete with energy production for this resource. A number of problems arise which have a direct impact on the fulfillment of policy objectives which are connected with its promotion. Primarily, the production of bioenergy has significant impacts on coupled biomass markets. Further, a change in production intensity or arable land use increases the use of nutrient loads and agro - chemicals. When evaluating... |

| This paper introduces a spatial bioeconomic model for study of potential cellulosic biomass supply at regional scale. By modeling the profitability of alternative crop production practices, it captures the opportunity cost of replacing current crops by cellulosic biomass crops. The model draws upon biophysical crop input-output coefficients, price and cost data, and spatial transportation costs in the context of profit maximization theory. Yields are simulated using temperature, precipitation and soil quality data with various commercial crops and potential new cellulosic biomass crops. Three types of alternative crop management scenarios are simulated by varying crop rotation, fertilization and tillage. The cost of transporting biomass to a specific... |

| Association of microalgae culture and anaerobic digestion seems a promising technology for sustainable algal biomass and biogas production. The use of digestates for sustaining the growth of microalgae reduces the costs and the environmental impacts associated with the substantial algal nutrient requirements. A natural marine algae–bacteria consortium was selected by growing on a medium containing macro nutrients (ammonia, phosphate and acetate) specific of a digestate, and was submitted to a factorial experimental design with different levels of temperature, light and pH. The microalgal consortium reached a maximum C conversion efficiency (i.e. ratio between carbon content produced and carbon supplied through light photosynthetic C conversion and acetate)... |

| Agriculture in Brazil, as well as worldwide, has been striving to meet the increasing demand for food, timber, fibers and bioenergy. While larger production is necessary, restrictions for expansion over natural environments increase. For the Brazilian beef industry, the current trend is towards little increase on herd numbers, despite reduction on grazing areas. This will lead to intensification of sown pastures, optimizing use of inputs, along with improved management, feeding and introduction of technologies like integrated systems. There is also a growing concern from the sector towards environmental preservation and the need for a more efficient use of inputs and natural resources if future demands are to be met. Therefore, agriculture will have to... |
