With This Project, Synagro Continues to Lead the Industry Toward Sustainable Solutions by Proactively Addressing the Customers’ Future Needs

BALTIMORE, Maryland, March 28, 2023 – Synagro Technologies, Inc., the preeminent provider of biosolids and residuals solutions services in North America and CharTech Solutions, a division of CHAR Technologies Ltd. (“CHAR”), a leading cleantech development and environmental services company, have announced a collaboration to develop a system to demonstrate the performance of CharTech Solutions’ proprietary high-temperature pyrolysis (HTP) process to treat thermally dried biosolids.

“Preliminary testing of HTP on biosolids has demonstrated the process can destroy PFAS contaminants, fix carbon in the form of biochar and produce renewable energy in the form of syngas” said Donald Song, senior project engineer, Synagro. “The unit will be self-contained with modules for feedstock handling, pyrolysis, biochar handling, gas clean-up and thermal oxidation and exhaust. The deployment of the unit will establish pyrolysis’ operational requirements, fate of PFAS, emissions and outputs at multiple locations. We believe this technology will be a powerful addition to our extensive experience in operating advanced thermal treatment processes for biosolids.”

“CHAR and Synagro have been working together for three years to test and apply HTP technology for biosolids to eliminate PFAS. Our partnership has evolved through each robust and detailed stage of the development process, and we are excited to move forward to deploy and demonstrate this innovative biosolids treatment technology at Synagro’s sites to validate HTP for commercial-scale applications,” said Andrew Friedenthal, director, Business Development, CHAR.

“CharTech Solutions’ HTP technology presents a breakthrough opportunity to transform wastewater treatment sludge/biosolids into renewable and valuable outputs including renewable energy and biochar, with the goal of decarbonization and PFAS elimination,” added Andrew White, chief executive officer, CHAR.
