Carbohydrates––in particular, starch, cellulose, and sucrose––
proteins and natural fats and oils are key raw materials for
the chemical industry using renewable resources. Although
biomass in general is available in large amounts (e.g., cellulose),
the annual production volumes of selected commodities
are still small compared to coal or crude oil. So far, the volumes
were adjusted according to the different demands. In
particular, in the case of natural oils and fats, the production
volume steadily increased from 30 million tons in 1960 to
131 million tons in 2004 (Petran et al., 2008). Most of it is used
for food, a minor amount for animal feed and chemistry (Burt,
2004). Until now, availabilities and the different applications
were quite balanced
