Pyrolysis Pioneer: Synagro and CHAR Tech’s Bold Move Against PFAS Pollution

The threat of per- and polyfluoroalkyl substances (PFAS) to public health and ecosystems has become a global crisis, prompting urgent calls for innovative waste management solutions. Now, a groundbreaking partnership between Synagro Technologies, Inc. (NYSE: SNG), CHAR Tech Solutions, and the Baltimore City Department of Public Works (DPW) is poised to redefine how municipalities tackle this “forever chemical” menace. Their commercial-scale pyrolysis pilot project—a first-of-its-kind initiative—could unlock significant investment opportunities in sustainable waste-to-resource technologies.

The PFAS Problem: A Growing Regulatory and Environmental Liability
PFAS, widely used in industrial processes and consumer goods, are persistent pollutants linked to cancer, liver damage, and other health issues. With regulators worldwide tightening restrictions, municipalities and utilities face mounting pressure to eliminate PFAS from wastewater biosolids. Traditional methods like landfill disposal or incineration are costly, environmentally damaging, and often ineffective. According to Baltimore’s DPW, constructing a PFAS-removal facility could cost over $100 million, underscoring the need for scalable, affordable alternatives.

The Solution: High-Temperature Pyrolysis (HTP) in Action
The pilot, launched in May 2025 at Synagro’s Back River Facility, deploys CHAR Tech’s proprietary HTP technology. This oxygen-free thermal process breaks down PFAS molecules into harmless byproducts while converting biosolids into two valuable outputs:
1. Syngas: A renewable synthetic gas usable for energy production.
2. Biochar: A carbon-rich material that enriches soil and sequesters carbon.

Ask Aime: How does the Synagro-CHAR Tech-Baltimore City DPW collaboration's groundbreaking pyrolysis pilot project address the PFAS crisis in Baltimore and its potential impact on waste management and sustainable technologies?

By destroying PFAS and transforming waste into resources, the HTP system addresses both environmental and economic challenges. Synagro, a leader in biosolids management, handles over 16 million tons of organic waste annually, positioning it to capitalize on this technology at scale.

Investor Implications: A Strategic Play in Sustainable Tech
The pilot’s success hinges on proving HTP’s efficacy in PFAS destruction—a critical hurdle for commercial adoption. If validated, the technology could:
- Reduce regulatory risk: Enable municipalities to comply with tightening PFAS regulations without exorbitant costs.
- Create new revenue streams: Sell syngas to energy markets and biochar to agricultural and carbon offset buyers.
- Enhance Synagro’s margins: Lower waste management costs while monetizing byproducts.

Synagro’s partnership with Baltimore—a city with 1.3 million residents—also serves as a replicable model for other municipalities. CHAR Tech, meanwhile, gains a foothold in the U.S. market, where its biocarbon could rival metallurgical coal in industries like steelmaking.

Market Context: A Race Against Time
The global PFAS mitigation market is projected to grow at a 10% CAGR, driven by stricter regulations. Synagro’s pilot aligns with this trend, offering a solution that mirrors the EU’s “circular economy” directives and U.S. EPA guidelines. However, challenges persist. While HTP avoids combustion-related emissions, scalability questions remain. Investors should monitor:
- PFAS destruction efficiency: Results from the pilot, expected by early 2026, will determine the technology’s viability.
- Cost competitiveness: HTP must outperform alternatives like chemical treatments, which can cost millions per pound of PFAS removed.

Conclusion: A Pivotal Moment for Environmental Innovation
The Synagro-CHAR Tech-Baltimore collaboration represents a critical step toward solving one of the 21st century’s most pressing environmental issues. With PFAS regulations set to intensify and sustainable technologies in high demand, this pilot could position Synagro and CHAR Tech as pioneers in a multi-billion-dollar market.

For investors, the partnership offers exposure to a sector with $50 billion+ in annual waste management spending and a clear path to decarbonization. While risks remain—particularly around scalability and regulatory adoption—the potential rewards are substantial. As Synagro’s Chief Commercial Officer Pam Racey noted, the pilot “leads the industry toward sustainable solutions by proactively addressing customers’ future needs.” With results imminent, this could be the year pyrolysis transitions from a promising experiment to a cornerstone of environmental stewardship—and a winning investment thesis.
