New Siberian idea: how to turn grain straw into pure biofuel

New Siberian idea: how to turn grain straw into pure biofuelIrkutsk scientists in Siberia have developed an eco-friendly method of pre-treating raw lignocellulose materials to produce sugars used in biofuel production.

Irkutsk State Technical University (ISTU) in Siberia announced last week that its scientists have developed an eco-friendly method of pre-treating raw lignocellulose materials to produce sugars used in biofuel production. Research conducted at the university?s chemistry and food technology chair is believed to have shown the ?efficiency of using supercritical carbon dioxide to remove impurities from grain crop straw and therefore speed up effective enzymic hydrolysis, thus receiving purer sugars.? According to Prof. Sergei Evstafyev, the project leader and head of the chair, this is the first time such application of carbon dioxide properties is suggested. In February 2013 ISTU had its lignocellulose pre-treatment technique and its proprietary pre-treatment machine patented in Russia. Sugars generated as a result of enzymic hydrolysis in agricultural waste, including oat and wheat straw, can be used as raw materials for production of biofuels, such as bioethanol and biobutanol...
