"Affirming long-standing incineration regulations, the Biden administration has withdrawn a plan to help ease the way for unchecked pyrolysis and gasification of plastic."
"Reversing its own Trump-era proposal, the Environmental Protection Agency has spurned a lobbying effort by the chemical industry to relax clean-air regulations on two types of chemical or “advanced” recycling of plastics.
The decision, announced by the EPA on May 24, covers pyrolysis and gasification, two processes that use chemical methods to break down plastic waste. Both have largely been regulated as incineration for nearly three decades and have therefore had to meet stringent emission requirements for burning solid waste under the federal Clean Air Act.
But in the final months of the Trump administration, the EPA proposed an industry-friendly rule change in August 2020 stating that pyrolysis does not involve enough oxygen to constitute combustion, and that emissions from the process should therefore not be regulated as incineration."
