Ökobilanz von Energieprodukten: Life Cycle Assessment of Biomass-to-Liquid Fuels
The study at hand has been elaborated as a follow-up study of a recent investigation on several types of biofuels. In that study the environmental impacts of several biofuel options like biogas, plant oil methyl ethers, ethanol and methanol have been investigated from a Swiss market perspective. The study investigated mainly renewable fuels, which are directly produced from a biomass resource by a physical, chemical or biological process like oil pressing, chemical reaction, fermentation or anaerobic digestion. The study concludes that with many biofuels it would be possible to reduce the emissions of greenhouse gases. But, on the other side there are severe disadvantages regarding several other environmental problems if biofuels are compared with fossil fuels.
