The production of biofuel feedstocks from agricultural and forestry sources has been considered for many years, particularly just after the 1970's "energy crisis". A number of environmental and economic benefits are claimed for biofuels. Worldwide interest reflect convergence of developed and developing country perspectives on the role bio-fuels can play in energy for sustainable development. The increase in bio-fuels utilization has also been accompanied over the past 3-4 years with policy decisions that encourage future growth of these fuels. The United States and several European Union member states already pursue successful bio-fuel policy. This work presents a review of the thermochemical and biochemical methods that could be used to produce bio-fuels and the production trends of the products in the world.

The most common renewable fuel today is ethanol produced from sugar or grain (starch); however, this raw material base will not be sufficient. Consequently, future largescale use of ethanol will most certainly have to be based on production from lignocellulosic materials. This review gives an overview of the new technologies required and the advances achieved in recent years to bring lignocellulosic ethanol towards industrial production. One of the major challenges is to optimize the integration of process engineering, fermentation technology, enzyme engineering and metabolic engineering.

Chemically biodiesel is monoalkyl esters of long chain fatty acids derived from renewable feed stock like vegetable oils and animal fats. It is produced by transesterification in which, oil or fat is reacted with a monohydric alcohol in presence of a catalyst. The process of transesterification is affected by the mode of reaction condition, molar ratio of alcohol to oil, type of alcohol, type and amount of catalysts, reaction time and temperature and purity of reactants. In the present paper various methods of preparation of biodiesel with different combination of oil and catalysts have been described. The technical tools and processes for monitoring the transesterification reactions like TLC, GC, HPLC, GPC, <sup> 1 </> H NMR and NIR have also been summarized. In addition, fuel properties and specifications provided by different countries are discussed.

Biodiesel is produced by transesterification in which oil or fat is reacted with a monohydric alcohol in the presence of a catalyst. The process of transesterification is affected by the mode of reaction, molar ratio of alcohol to oil, type of alcohol, nature and amount of catalysts, reaction time, and temperature. Various studies have been carried out using different oils as the raw material and different alcohols (methanol, ethanol, butanol), as well as different catalysts, notably homogeneous ones such as sodium hydroxide, potassium hydroxide, sulfuric acid, and supercritical fluids or enzymes such as lipases. Recent research has focused on the application of heterogeneous catalysts to produce biodiesel, because of their environmental and economic advantages. This paper reviews the literature regarding both catalytic and noncatalytic production of biodiesel. Advantages and disadvantages of different methods and catalysts used are discussed. We also discuss the importance of developing a single catalyst for both esterification and transesterification reactions.

Diesel greenhouse gas emissions are roughly four times as important as biodiesel emissions from oil seed crops. So presently, these two major performances of sustainability result very positive. For oil seed rape, development of acreage on deep soils, decrease of N fertilisation rate, decrease of energetic costs in N fertilisers industry and development of minimum tillage should continue to improve on energetic balance. On the contrary, for sunflower, the present trend is not an improvement of its energetic balance. In order to go more ahead, more abrupt changes are needed: as reduction ofN applications for sunflower, and oil seed rape plant breeding in order to increase N content of seeds and decrease N content of its harvest residues. -20- Biocarburants AI: AB CC: 001D06B06E; 002A32C08; 230 DEE: Industrialized-country; Producing-country; Agricultural-industry; Energy-industry; Oils-andfats-industry; Vegetable-oil; Agriculture-; Sustainable-development; Alternative-motor-fuel; Europe-; Compositae-; Spermatophyta-; Angiospermae-; Dicotyledones-; Cruciferae-; Non-foodproducts; Non-food-industries; vegetable-oil-sector; System-sustainability; Sunflower-seed; Rapeseed-; 2000-2010-; R-and-D-program; Perspective-; State-of-the-art; France-; Sunflower-oil; Rapeseed-oil; Nitrogen-fertilizer; Fatty-acid-methyl-ester; Nitrogen-fertilization; Oilseed-; Agricultural-development; Sustainable-agriculture; Production-system; Agricultural-production; Helianthus-annuus; Brassica-napus-var.-oleifera; Energy-crop; Energy-plantation; Life-cycle(environment); Greenhouse-gas; Energy-balance; Oil-plant-(vegetal); Plant-production; Diesel-fuel; BiofuelDEF: Pays-industrialisé; Pays-producteur; Industrie-agricole; Industrie-énergie; Industrie-corpsgras; Huile-végétale; Agriculture-; Développement-durable; Carburant-remplacement; Europe-; Compositae-; Spermatophyta-; Angiospermae-; Dicotyledones-; Cruciferae-; Produit-nonalimentaire; Industrie-non-alimentaire; Filière-oléagineux; Durabilité-système; Ester-méthyliquehuile-tournesol; Ester-méthylique-huile-colza; Graine-tournesol; Graine-colza; 2000-2010-; Programme-R-et-D; Perspective-; Etat-actuel; France-; Huile-tournesol; Huile-colza; Engrais-azoté; Acide-gras-ester-méthyle; Fertilisation-azotée; Graine-oléagineuse; Développement-agricole; Agriculture-durable; Système-production; Production-agricole; Helianthus-annuus; Brassica-napusvar.-oleifera; Plante-énergétique; Plantation-énergétique; Cycle-vie-(environnement); Gaz-effetserre; Bilan-énergétique; Plante-oléagineuse; Production-végétale; Carburant-diesel; BiocarburantDEA: oil-seed-crops; biodiesel-; energetic-balance; greenhouse-gas JN: OCL.-Oléagineux,-corps-gras,-lipides LOC: INIST-CNRS, Shelf Number 22926, INIST No. 354000158842250060 AN: 18240396; 060526776 SI: INIST CR: Copyright 2006 INIST-CNRS.

Efforts to reduce the enormous human health, socioeconomic, and environmental impacts by shifting to cleaner cookstoves and cleaner biomass-derived fuels have had some success, but much more needs to be done, possibly including the expanded use of fossil-derived fuels. Concurrently, biomass is rapidly expanding as a commercial energy source, especially for transport fuels. Bioenergy can positively contribute to climate goals and rural livelihoods; however, if not implemented carefully, it could exacerbate degradation of land, water bodies, and ecosystems; reduce food security; and increase greenhouse gas (GHG) emissions. For large-scale commercial biofuels to contribute to sustainable development will require agriculturally sustainable methods and markets that provide enhanced livelihood opportunities and equitable terms of trade. The challenge lies in translating the opportunity into reality.

JAN-MAR 2007; 27 (1) : 1-12 DT: Review PY: 2007 IS: 1774-0746 LA: English AB: Transportation biofuel production in the United States is currently dominated by ethanol from the grain of maize and, to a much lesser extent, biodiesel from soybeans. Although using these biofuels avoids many of the environmentally detrimental aspects of petroleum-based fossil fuels, biofuel production has its own environmental costs, largely related to fossil fuel use in converting crops to biofuels and crop cultivation itself, including ecological damages caused by nitrogen and phosphorus fertilizers, pesticides, and erosion. A new generation of biofuels derived from lignocellulosic sources offers greatly reduced environmental impacts while potentially avoiding conflicts between food and energy production. In particular, diverse mixtures of native prairie species offer biomass feedstocks that may yield greater net energy gains than monoculture energy crops when converted into biofuels, while also providing wildlife habitat and enriching degraded soils through carbon sequestration and nitrogen fixation. Ultimately, as demand for both food and energy rise in the coming decades, greater consideration will need to be given to how land can best be used for the greater benefit of society.

The potential synergies to be drawn with materials markets, agricultural practice reform and a broad range of policy promotion mechanisms tackling climate change, and energy security all have substantial influence on the sector. Furthermore, the identification of the best options for biomass to energy conversion is complex to ascertain owing to the broad range of potential indicators in assessing the impact and benefits of any application and the geographical specificities of any possible solutions, as well as the potential improvements in key metrics as capacity expands. This work assesses the current approaches of bioenergy systems assessment in identifying those pathways which represent potentially optimal applications with regard to climatic and energy security benefits. Substantial potential for lignocellulosic biomass pathways is identified with a particular focus on the development of bioethanol for substitution of gasoline in road vehicles and the use of biorefineries to ensure maximum utilization of biomass. The potentials for whole-system analyses are highlighted.
