Environmental and social dimensions of fuel ethanol production in Cradock, South Africa, in the context of the wider biofuels debate
Liquid biofuels are fossil fuel replacements in the form of fuel ethanol and biodiesel. Advocates of biofuels highlight their potential to mitigate climate change from reduced greenhouse gas emissions and socio-economic benefits for countries that achieve a higher degree of self-reliant energy …

Microlepidoptera of Illinois hill prairies
… (hill prairie) and a managed community type (biofuel feedstock). In two Illinois hill prairies differing in size, latitude, and plant composition, alpha diversity of Pyraloidea and Tortricidae was similar, but the prairies were found to support different sets of species of these moth groups. …

Regrowth of Chlorella sorokiniana on Recycled Media with Replenished Nutrients
… increase the efficiency and reduce the cost of biofuel production from algae feedstocks. Without recycling media, the cost of algae based biofuel production would be prohibitively high and large scale algae based biofuel production would not be economically viable. The ratio of media recycled to …
