Synagro, CHAR Tech and the Baltimore City Department of Public Works Partner to Test Commercial-Scale Pyrolysis Pilot for PFAS Destruction

Synagro and Partners to Test Commercial-Scale Pyrolysis Pilot for PFAS Destruction, Syngas Recovery and Biochar Production

BALTIMORE, May 6, 2025 /PRNewswire/ -- Synagro Technologies, Inc., North America's leading provider of sustainable solutions for biosolids, organics and residuals, is pleased to present a commercial-scale pilot of CHAR Tech's pyrolysis process with CHAR Tech Solutions, a division of CHAR Technologies Ltd., a leading cleantech development and environmental services company, and the Baltimore City Department of Public Works (DPW). The demonstration will be held May 9, 2025, at the Synagro Back River Facility at the Baltimore City Back River Wastewater Treatment Plant as part of the Water Environment Federation's Residuals & Biosolids and Innovations in Treatment Technology Conference (RB/ITT25) being held at the Baltimore Convention Center May 6-9, 2025.

"We are excited to feature a demonstration of our commercial-scale pilot of Char Tech's pyrolysis process, leading the industry toward sustainable solutions by proactively addressing customers' future needs," said Pam Racey, Chief Commercial Officer, Synagro, and RB/ITT25 Conference Co-Chair.

CHAR Tech's proprietary high-temperature pyrolysis (HTP) technology processes organic material into high-value renewable energy and bioproducts, such as a solid biochar and renewable synthetic gas – syngas. CHAR Tech's HTP system indirectly heats materials in the complete absence of oxygen, and with no oxygen, the material cannot burn and, therefore, should not cause odors.

"This project represents a major step forward in tackling one of the most pressing environmental challenges of our time," said Andrew White, Chief Executive Officer, CHAR Tech.

"DPW is proud to participate in this groundbreaking demonstration, which reflects our commitment to environmental leadership and forward-thinking innovation," said Director Khalil Zaied, Baltimore City Department of Public Works. "By supporting cutting-edge technologies that address PFAS and turn waste into usable resources, we're taking meaningful steps to protect our environment – both for today's residents and for future generations of Baltimoreans."

Between May 2025 and December 2025, Synagro and CHAR Tech Solutions will measure, test and evaluate the effectiveness of the HTP process to destroy PFAS chemicals from biosolids.
