Cambi has agreed to deliver a thermal hydrolysis plant to the Washington Suburban Sanitation Commission’s (WSSC) Piscataway Bioenergy Project.
The new plant will be located 20 kilometres south of the DC Water site and treat sewage sludge from five wastewater treatment plants (WWTP) in the Montgomery and Prince George’s counties in Maryland, US.
The Piscataway Bioenergy Project will become WSSC’s largest and most technologically advanced plant yet. Once complete in 2024, the project will transform WSSC’s biosolids handling, reducing the volume and enabling it to sell the biosolids as an exceptional quality class A fertiliser.
According to Cambi, which supplies technology for sustainable biosolids management at WWTPs, the project will see reduced disposal costs and increased income from biogas production, as well as saving WSSC and its ratepayers more than $3 million (€2.51 million) in annual operating costs. The project will also reduce WSSC’s greenhouse gas emissions by 15%, equivalent to removing 5,000 cars from traffic.
CambiTHP was pre-selected by WSSC as a ‘critical technology’ for the project, now delivered by the design built team of PC Construction, Stantec and Hazen. Jay Fayette, PC Construction’s president and CEO, said: “This project is a game-changer, utilising cutting-edge thermal hydrolysis technology to reduce costs and increase efficiency and sustainability.”
Per Lillebø, CEO at Cambi, said the new contract is a “welcome recognition” of its commitment to the US market. “This is Cambi’s eighth project in the US, strengthening our position as a leader in thermal hydrolysis and the advanced treatment of biosolids in the US,” said Lillebø.
“We look forward to working with PC Construction to make the Piscataway Bioenergy Project a success and are committed to support WSSC realise the full potential of their investment.”
