Wastewater Bioenergy Project Selected by Department of Energy
Research and Industry Partners Collaborate on a Pilot-Scale Project to Produce Finished Fuels from Wastewater Sludge

(Alexandria, VA) - A consortium led by the Water Environment & Reuse Foundation (WE&RF) has been selected by the Department of Energy for award negotiations to begin Phase 1 design and planning for a pilot plant to produce clean hydrocarbon fuels at a municipal wastewater treatment facility. The project will use breakthrough technology to produce fuels such as gasoline, jet fuel, diesel and renewable natural gas from wastewater solids.

The Central Contra Costa Sanitary District, near Oakland, California, will host the pilot system. The consortium includes WE&RF representing many of the 16,000 wastewater systems in the USA, Genifuel Corporation with technology from DOE’s Pacific Northwest National Laboratory, Merrick & Company, Southern California Gas Company, Tesoro Corporation, Metro Vancouver, MicroBio Engineering, Brown and Caldwell, and over a dozen utility partners.

The technology, called Hydrothermal Processing, converts waste solids from a wastewater treatment plant into biocrude oil and methane gas in less than one hour. The biocrude oil replaces fossil oil, providing green fuels with nearly zero net new carbon emissions. The methane gas can be used in the same ways as fossil natural gas. Biocrude oil produced in the system will be refined in an existing refinery, while the methane gas will be sold for transport in the gas pipeline system or used at the pilot plant to offset power needs elsewhere in the plant. If fully implemented in wastewater treatment operations across the U.S., the technology will produce more than two billion gallons of gasoline equivalent per year. The system also produces fertilizer byproducts. 

The selection was made by the Bioenergy Technologies Office, part of the Office of Energy Efficiency and Renewable Energy at DOE. “We are very proud that our consortium was selected for award negotiation” stated Melissa Meeker, Chief Executive Officer of WE&RF. The partners have demonstrated that they can convert wastewater solids into renewable hydrocarbon fuels using existing infrastructure, while replacing fossil fuels and reducing greenhouse gas emissions. A successful demonstration via the pilot plant in this project could transform wastewater treatment while contributing a substantial amount of clean biofuel.

The Water Environment & Reuse Foundation (WE&RF) is a nonprofit (501c3) organization officially formed in July 2016 as the result of the merger of Water Environment Research Foundation and the WateReuse Research Foundation. The merged research foundation, with a combined research portfolio representing over $200 million, conducts research to treat and recover beneficial materials from wastewater, stormwater, and seawater including water, nutrients, energy, and biosolids.
