Modern biotechnology changes straw into something that's needed much more urgently: sustainable and climate-friendly fuel. In the face of climate change and dwindling reserves of fossil fuels, the search is on for an environment friendly alternative, especially in the automotive sector which consumes about 50 percent of the world's crude oil production. Biofuels already exist, but so far they have been produced from canola, corn or cereals -- edible plants also needed as food. »With the innovative sunliquid process, Clariant has now succeeded in converting difficult to access sugar from previously unusable plant residues like cereal straw, corn stover or residues from sugar cane almost completely into high-quality ethanol,« says Professor Dr. Andre Koltermann, Head of Clariant's Biotech & Renewables Center. The cellulosic ethanol produced by this process is a second-generation biofuel distinguished by a class climate balance.
