Many conversion technologies that produce drop-in biofuels or biomass-based bioproducts utilize cellulosic sugars or lignin in their process. As a result, both lignocellulosic sugars and lignin have become necessary intermediates for advancing research.

Over the past several years, a number of companies have entered this field and are producing lignocellulosic sugars and/or lignin. However, DOE said, is not clear how many of these companies are willing and able to sell these products to the research community, and what quantities are available.
