Burnham RNG LLC (Burnham) has selected Gross-Wen Technologies to provide wastewater treatment at the company's proposed Pasco, Washington Resource Recovery Center (PRRC or Project). The PRRC is an innovative industrial wastewater treatment facility that will clean wastewater from the City of Pasco's (City) various agribusinesses for agricultural re-use and capture biogas and convert it into renewable natural gas (RNG). 

The Project represents a 30-year public private partnership with the City of Pasco for Burnham to build, own and operate the PRRC on behalf of the City. The RNG will be sold under a long-term contract, allowing the City to reduce net treatment costs and take advantage of tax incentives currently available for RNG projects under the Inflation Reduction Act. The Project will support the growth of the City's booming agribusiness sector while turning wastewater into clean energy and providing clean water and nutrients to irrigate and fertilize City-owned farmland.

The Project is being constructed under and EPC contract with Swinerton Builders, Inc. and will use Gross-Wen's innovative and patented Revolving Algae Biofilm (RAB) treatment technology to cost-effectively and sustainably remove nutrients from the process of wastewater. The PRRC will enable the reuse of an estimated 1.5 billion gallons of wastewater per year and is estimated to produce enough RNG to supply over 4,500 Washington state residential customers each year with a clean and renewable source of natural gas. 

GWT co-founder and president Dr. Martin Gross expressed his company's excitement to provide an innovative, sustainable treatment solution to this new facility: "We're excited to play a part in this exciting project by providing a state of the art, innovative, environmentally sustainable and energy efficient wastewater treatment solution." 

According to Burnham CEO Chris Tynan, "Gross-Wen's technology is one of the most sustainable and energy efficient ways to remove nutrients from wastewater. The GWT technology will assist our project to utilize wastewater as a source of clean energy, clean water and nutrients. While improving environmental outcomes for Pasco."
