Is the US Finally Ready to Recycle Smarter?

A US EPA proposal to reclassify pyrolysis as manufacturing could unlock billions stalled in advanced plastics recycling infrastructure

4 May 2026

A regulatory impasse that has deterred billions of dollars in advanced plastics recycling investment may be nearing resolution. In March 2026, the Environmental Protection Agency issued a comment solicitation seeking public input on whether pyrolysis technologies should be classified as manufacturing rather than incineration under the Clean Air Act. The comment period closed in early May, and the agency is now in review. For investors and facility developers, it is the clearest federal signal in years that large-scale chemical recycling infrastructure has returned to the national agenda.

Pyrolysis breaks down used plastics at high temperatures in low-oxygen environments, converting waste material into hydrocarbon feedstocks that can be reprocessed into new resins. The technology is widely deployed in Europe and Asia, but in the United States it has occupied a regulatory gray zone, deterring companies from committing to the multihundred-million-dollar construction costs the sector demands. Several projects have been delayed or abandoned as developers awaited federal clarity.

Industry groups welcomed the announcement. America's Plastic Makers described the E.P.A. action as a significant step toward spurring innovation and strengthening American competitiveness. Since 2017, more than 90 recycling projects with a declared value exceeding eight billion dollars have been announced nationwide, many stalled by permitting uncertainty alone. Operators including Brightmark, which runs a pyrolysis facility in Indiana, have said that investment in new capacity requires the kind of regulatory certainty federal rules have, until now, failed to provide.

The E.P.A. proposal runs parallel to a legislative effort. The Recycling Technology Innovation Act, introduced in Congress in December 2025, seeks to formally classify chemical recycling as manufacturing at the federal level, offering a statutory foundation more durable than regulatory guidance alone.

Yet environmental advocates are urging restraint. The Natural Resources Defense Council has warned that shifting pyrolysis oversight from Section 129 to Section 111 of the Clean Air Act could reduce the range of pollutants subject to federal controls, with consequences for communities near such facilities. Critics have also noted that some plastic processed through pyrolysis is redirected to fuel rather than new material. The agency said those perspectives would be considered in its final rulemaking. For brand owners facing mandatory recycled-content deadlines, the outcome could shape investment decisions across the sector for years to come.
