grain - Getreide
sugar beet/-cane - Zuckerrübe/-rohr
rapeseed - Raps
mash - Brei
yeast - Hefe
fermentation - Gärung
Biofuels in Germany
biofuel with bad CO2-footprint
- energy intensive agriculture
- inefficient transformation to usable fuel
biofuel made of palm/soya oil ?
- 2008 GREENPEACE analysis:
global farmland competition: "food" vs. "biomass"
higher grain/food prices!
Smart biofuel production
slurry - Gülle
oil mill - Ölmühle
Production of bioethanol
