Norway-headed biosolids technology supplier Cambi AS has recently announced that it has signed a new contract to deliver a thermal hydrolysis plant to the Washington Suburban Sanitation Commission’s (WSSC) Piscataway Bioenergy Project in Washington DC. The new plant will be located 20 km south of the DC Water site and treat sewage sludge from five wastewater treatment plants (WWTPs) in Montgomery and Prince George’s counties in Maryland (MD).
The US$262 million Piscataway Bioenergy Project will become WSSC’s largest and most technologically advanced plant yet. The project will convert wastewater biosolids into renewable biogas, which will then be used by combined heat and power (CHP) engines to help power the facility.
A portion of the biogas generated will also supplement the local community’s energy supply. Once complete in 2024, the Bioenergy Project will transform WSSC’s biosolids handling, significantly reducing the volume and enabling WSSC to sell the biosolids as exceptional quality (EQ) Class A fertiliser.
Reduced disposal costs and increased income from biogas production will save WSSC and its ratepayers more than US$3 million in annual operating costs. The project will also reduce WSSC’s greenhouse gas (GHG) emissions by 15 percent.
This project is a game-changer, utilizing cutting-edge thermal hydrolysis technology to reduce costs and increase efficiency and sustainability, said Jay Fayette, President, and CEO, PC Construction.
Building on the success of Cambi’s first American project with DC Water, “CambiTHP” was pre-selected by WSSC as a critical technology for the project now being delivered by the design-build team of PC Construction, Stantec, and Hazen and Sawyer.
The new contract is a welcome recognition of our commitment to the American market. This is Cambi’s 8th project in the United States, strengthening our position as a leader in thermal hydrolysis and the advanced treatment of biosolids in America. We look forward to working with PC Construction to make the Piscataway Bioenergy Project a success, and are committed to supporting WSSC to realise the full potential of their investment, said Per Lillebø, CEO of Cambi.
