Distillation is a challenge to all fermentation processes
A challenge common to all ethanol fermentation processes - ethanol produced in fermentation process is highly diluted with water. In fact, the ethanol produced from fermenting grain typically makes up only 15-20% of the solution, with the remainder water. For cellulosic ethanol, the crude ethanol is typically less than 5%. Separating water and ethanol an energy-intensive process. Even where the EROEI is high, as in sugarcane ethanol, distillation takes substantial amount of energy. - Read More

Prevention of biofuel feedstock from invading the ecology
a balance must be struck between designing biofuel feedstock crops to require minimal inputs and yet preventing them from surviving outside the cultivated environment. This is true especially in cases when the feedstock introduced can become invasive - Read More

Jatropha displacing Mindanao food crops in Philippines
Dec 2008 - BAGUIO CITY – Indigenous women leaders from Mindanao said the expansion of jatropha plantations in Sarangani and in other provinces in Mindanao has displaced traditional food crops, which forced members of the B’laan tribe to go hungry. In a recent commemoration of the international day for the elimination of violence against women here, Lorna Mora, a B’laan leader, said 500 hectares of agricultural land in Sarangani were used to grow jatropha, locally known as tuba-tuba. - Read More

Corn ethanol consumes vast amounts of water and fossil fuel
Corn ethanol, for instance, utilizes vast amounts of water and fossil fuel based fertilizer and requires considerable energy to produce - making it a highly inefficient, water consuming and polluting biofuel source. - Read More
