When former top Environmental Protection Agency official Judith Enck noticed a cavalcade of chemical and plastics industry lobbyists visiting the agencys Washington headquarters in February, she wondered what could be up. An answer came weeks later: The agency is moving toward resurrecting a proposal from the first Trump administration to ditch Clean Air Act regulations involving one of the industrys go-to methods for chemically processing plastic waste into new industrial feedstocks or fuels.
The EPA is curiously approaching this by embedding a request for comments on so-called advanced recycling via a method known as pyrolysis in a rulemaking on an entirely different category of waste incineration.I thought, could it be a mistake, or are they quietly trying to push this through? Enck, a former EPA regional administrator during the Obama presidency, wondered in an interview on Tuesday. Just one paragraph related to advanced recycling of plastics was included in a 17-page Federal Register notice for a proposed rule on wood incineration.
EDIT
Its not recycling, said James Pew, director of the federal clean air practice at the environmental group Earthjustice. To the extent these incinerators produce anything significant other than toxic pollution, a very small portion of the plastic waste they burn is turned into an oily waste that can be fed back into the chemical production process or burned [as] dirty fuel. And it encourages unlimited production of single-use plastics.
EDIT
The details of what the EPA will propose have not yet been revealed. But the agencys March 17 announcement and supporting documents point to the kind of regulatory relief it sought to provide during the first Trump termbefore running out of time. Pyrolysis has largely been regulated as incineration for three decades and has therefore had to meet stringent emission requirements for burning solid waste under the federal Clean Air Act. In the final months of the first Trump administration, the EPA proposed an industry-friendly rule change stating that pyrolysis does not involve enough oxygen to constitute combustion, and that emissions from the process should therefore not be regulated as incineration.

(38,059 posts)I personally believe that the only real viable option is steam reforming, about which I have collected a lot of information over the years.
Steam reforming, with clean thermal energy, which is decidedly not accessible by any form of combustion, but is accessible with nuclear energy, preferably in a process intensification setting, yields syn gas, a mixture of carbon monoxide and hydrogen that can be catalytically be used to synthesize methanol. There is an industrial process known as MTO - methanol to olefins - that can, again in theory, be used to produce new polymers.
It is, in theory at least, to close the carbon cycle with polymers.
A polymer is carbon sequestered in use. This may or may not sound, or even be, glib but from my perspective is worthy of consideration, particularly where polymers are utilized in long use structural and other similarly used materials.
None of this is claimed to be cheap or easy to do. It is only feasible, which is a different thing than likely to be practiced.
The science and engineering are well known.
I note that heating natural waters, including but not limited to seawater, as well as waste water to supercritical temperature and pressures will effectively destroy micro and nano plastics therein. This conceivably could have the effective result of actually removing and cleaning pollution.
