EPA Proposal to Deregulate Plastic Pyrolysis Plants Sparks Debate

The U.S. Environmental Protection Agency has proposed removing air emission regulations for plastic pyrolysis, or “chemical recycling,” facilities—plants that convert plastic waste into fuel or chemicals. Currently classified as incinerators under the Clean Air Act, these units must meet strict pollution controls, monitoring, and reporting standards.

The proposed change, embedded within a broader rule on disaster-related permitting, seeks to exclude pyrolysis units from the definition of municipal waste combustion systems. Critics argue this could leave many facilities largely unregulated, as most would not qualify as major sources of hazardous emissions.

Environmental groups warn that pyrolysis can generate harmful pollutants such as dioxins and formaldehyde due to incomplete combustion. However, industry bodies like the American Chemistry Council support the move, citing the technology’s potential to convert plastic waste into valuable raw materials.

The proposal is open for public comment, with a hearing scheduled in April.
