They use agro-waste from cracked soy beans, rice and cotton seed hulls, grain sorghum, milo and jatropha and it is turned into bio-crude oil . This crude can then be further refined into everything from gasoline to jet fuel and just about every petrochemical in between. It is very nice to know that there is a bio fuel that does not compete with market produce. They also claim that their fuel burns to near 100 percent efficiency. Maybe we aren't far from a banana peel powered car."
