  The newest pretreatment method to get investor backing is actually a very old method: hydrochloric acid.

  A lot of attention has focused on the development of more efficient cellulases and hemi-cellulases to convert cellulosic feedstocks into fermentable sugars. Once this step becomes efficient, biofuels come much closer to a practical reality. Well, a company called HCL Cleantech has just received investments from high profile VCs Burrill & Co. and Khosla Ventures based on a different, enzyme-free approach. HCL Cleantech claims a low-cost biomass to sugars conversion using good, old concentrated hydrochloric acid, offering a process that uses little water and is self-sufficient energetically. As a path to fermentable sugars, the methods would help biofuels development broadly, whether the product is ethanol, butanol, or hydrocarbons. R & D is ongoing in Israel currently, with a pilot plant slated for the USA in 2010. Read the full story here.
