Concentrated hydrochloric acid-driven hydrolysis provides a most powerful and the only industrially proven technology for converting Biomass to sugars that can be fermented to ethanol, or other bio‑fuels, as well as a large variety of bio-products, food and feed.
HCL CleanTech’s use of concentrated hydrochloric acid (HCl) efficiently hydrolyzes all cellulosic materials and so allows a large variety of feedstocks to be used with minimal configuration. Using the proprietary technologies developed in our laboratories, HCL CleanTech has radically improved the recovery of the acid, as well as the recovery of valuable byproducts such as high quality lignin and high quality tall oils. The process uses virtually no virgin water and the lignin produced provides more than the energy necessary for the process.
Cost of the sugars produced by HCL CleanTech is more than 17% lower than the cost of corn mill sugars, while their quality is very similar. HCL CleanTech’s process is more than 80% environmentally friendlier than corn mill processes (Life Cycle Analysis comparison).
In June 2010, HCL CleanTech has begun running its first pilot plant at Southern Research Institute, NC.

In May 2009 HCL CleanTech has closed its Series “A” financing with Burrill & Company, Khosla Ventures and a group of founders and angels led by Zohar Gilon.
