Brassica biodiesels: Past, present and future
TLDR
In this paper, the performance and prospects of rape biodiesel production on a global basis using some 40 life cycle assessments (LCAs) are reviewed. And the consequences of large-scale renewable energy action plans have been considered.Abstract:
Essential sustainability requirements for biodiesel are that the product should be truly renewable and have a lower negative environmental impact than fossil fuels based on the latest insights. Biodiesel is not a most sustainable product in all geographical circumstances. This survey paper reviews the performance and prospects of rape biodiesel production on a global basis using some 40 life cycle assessments (LCAs). The paper identifies best (agricultural) practice and laggards. Life cycle energy balance depends on specific climatic conditions, and the agro- and processing technologies used. Alternative oilcrop cultivation practices and technologies were assessed. Opportunities to improve rape biodiesel life cycle energy efficiency and environmental impact by implementing new technologies in agriculture as well as in industrial processing have been identified for various Brassica oilcrop cultivars in relevant production areas. The consequences of large-scale renewable energy action plans have been considered. Improvements are needed for rape biodiesel to stay in business. The paper concludes with perspectives and recommendations.read more

Issues of social acceptance on biofuel development
TL;DR: In this article, the authors provided discussion on social acceptance in biofuel context and concluded that biofuel development will be constraint if social acceptance issues remain neglect, and pointed out different societal groups will demand specific consideration for either support or oppose biofuel.

Use of U.S. Croplands for Biofuels Increases Greenhouse Gases Through Emissions from Land-Use Change
Tim Searchinger,Ralph E. Heimlich,Richard A. Houghton,Fengxia Dong,Amani Elobeid,Jacinto F. Fabiosa,Simla Tokgoz,Dermot J. Hayes,Tun-Hsiang Yu +8 more
TL;DR: This article found that corn-based ethanol, instead of producing a 20% savings, nearly doubled greenhouse emissions over 30 years and increased greenhouse gases for 167 years, by using a worldwide agricultural model to estimate emissions from land-use change.

Land Clearing and the Biofuel Carbon Debt
TL;DR: Converting rainforests, peatlands, savannas, or grasslands to produce food crop–based biofuels in Brazil, Southeast Asia, and the United States creates a “biofuel carbon debt” by releasing 17 to 420 times more CO2 than the annual greenhouse gas reductions that these biofuel reductions would provide by displacing fossil fuels.

Environmental, economic, and energetic costs and benefits of biodiesel and ethanol biofuels
TL;DR: Transportation biofuels such as synfuel hydrocarbons or cellulosic ethanol, if produced from low-input biomass grown on agriculturally marginal land or from waste biomass, could provide much greater supplies and environmental benefits than food-basedBiofuels.
