Catechyl lignin found to withstand harsh measures during lignocellulosic feedstocks deconstruction [Full subscriber]
Researchers at the University of Wisconsin-Madison and Great Lakes Bioenergy Research Center (GLBRC) with partners at the Center for Bioenergy Innovation (CBI) have shown that a recently-discovered variety of the substance, catechyl lignin (C-lignin), has attributes that could make it well-suited as the starting point for a range of bioproducts.
Lignin can now be efficiently and cost-effectively separated from lignocellulosic feedstock such as sawdust, by using eutectic solvents. VTT Technical Research Centre of Finland has developed solvents which are able to extract 50% of the lignin from wood in a pure form that retains its natural chemical structure during processing.
Last year, 8.6 tonnes of cane was required to produce 1 tonne of sugar compared with 8.36 t this year. “However, this could go up slightly as we move towards the end of crushing at all mills because cane maturity has peaked in most areas,” Khan said.
