Coversion of waste water treatment plant fats oils and greases "brown grease" into bio diesel using supercitical fluids and robust catalyst processes./ Same as LOI on headers

The Department of Energy has a mission to ensure America's prosperity and security by addressing energy and environmental challenges. This Phase I project aims to produce domestic, economic and environmentally responsible biodiesel fuel from brown grease, a waste that is
currently disposed in landfills or incinerated. The conversion of "brown grease" from wastewater treatment plant’s fats oils and greases
(WWTP FOG) has the potential to generate over 500 million gallons of biodiesel per year. The proposed project will test both pretreatment by supercritical fluids of the brown grease as well as development of robust catalysts using supercritical process and a final cleaning of the product using supercritical fluids to produce a high quality industrial biodiesel. CF Tech is teaming with Idaho National Laboratory, a pioneer in supercritical and catalyst reactions including their
patented SSC process, and Mr. Richard Madrak, President of Waste Resources Recovery, Inc., a consultant within the industry. In prior work, CF Tech and INL have successfully used supercritical fluids in similar developments. Commercial application and benefits of this successful technology will be to manufacture and
install conversion plants at wastewater treatment plants around the country to reduce landfill and incineration disposal, while producing high value crude bio-oil. To be economically viable, biofuels need low cost feedstocks, WWTP brown grease meets that requirement as a no cost or negative value feedstock.
