EPA may ease plastics‑to‑products permitting
The EPA is considering a proposal to stop classifying a plastics‑recycling technology as a form of incineration, which would reduce permitting hurdles for facilities that turn plastic waste into products. This regulatory reclassification could change the permitting pathway and oversight those facilities face. (news.bloomberglaw.com)
The Environmental Protection Agency is weighing a rule change that would stop treating some plastic-pyrolysis units as incinerators under federal air rules. (federalregister.gov) Pyrolysis heats plastic waste in little or no oxygen and turns it into oil, fuel, or chemical feedstocks rather than burning it in open flame. The Environmental Protection Agency said in a 2021 rulemaking notice that pyrolysis and gasification are “heat induced thermal decomposition processes” used to convert plastics and other feedstocks into fuels and chemical commodities. (epa.gov, federalregister.gov) The current fight is over a definition in the Other Solid Waste Incinerators rule, a Clean Air Act program for nonhazardous waste-burning units. The agency’s March 20, 2026 proposal asks whether to remove the term “pyrolysis/combustion units” from the definition of “municipal waste combustion unit,” and comments are due by May 4, 2026. (epa.gov, federalregister.gov, wastedive.com) That wording change would shift the permitting path for plants that turn discarded plastic into products. Waste Dive reported the American Chemistry Council said the change would make permitting and regulatory processes “more consistent across the country” for chemical-recycling facilities. (wastedive.com, news.bloomberglaw.com) This is a reversal of the Biden administration’s last formal step on the issue. In May 2023, the Environmental Protection Agency withdrew a 2020 Trump-era proposal that would have removed pyrolysis units from the incinerator definition, and in June 2025 it finalized an Other Solid Waste Incinerators review without making that carveout. (epa.gov, mccoyseminars.com) Industry groups have pushed for years to classify advanced recycling as manufacturing instead of waste disposal or incineration. Waste Dive reported the American Chemistry Council and the Plastics Industry Association support the change, and Beveridge & Diamond said 27 states have already designated advanced recycling as manufacturing under state law. (wastedive.com, bdlaw.com) Environmental groups say the federal proposal could strip away air-pollution controls rather than clarify them. Chemical & Engineering News quoted Earthjustice attorney James Pew saying pyrolysis units are not listed under other hazardous-air-pollutant programs, and Bloomberg Law reported advocacy groups attacked the proposal in public meetings this month. (cen.acs.org, news.bloomberglaw.com) The Environmental Protection Agency has not issued a final decision, and the March proposal is still open for public comment. What happens next is narrower than the politics around plastic recycling: the agency will decide whether one definition in one Clean Air Act rule still covers pyrolysis plants.
