Biofuels Firm HCL Raises Venture Funds
HCL CleanTech, a cellulosic biofuel start-up, has raised its first round of funding from venture capital firms Burrill & Co. and Khosla Ventures. HCL claims to have improved a World War II-era German process for converting cellulose to sugar using concentrated hydrochloric acid. The company says it has developed a solvent extraction method to reclaim the acid for reuse. HCL says its process allows users to accept a wide variety of feedstocks without pretreatment and requires less water and energy than sulfuric acid or enzymatic methods.
