TSCA NEW CHEMICALS PROGRAM (NCP) CHEMICAL CATEGORIES.

EPA's Office of Pollution Prevention and Toxics (OPPT) groups chemicals with shared chemical and toxicological properties into categories so that PMN reviews are facilitated. PMN submitters and EPA reviewers benefit from the accumulated data and past decisions represented by a category.EPA considers all PMNs,including new chemical substances which fall within such categories,on a case-by-case basis and uses the most appropriate structural analogue to support any concerns for health or environmental effects.

Chemical Recyclingin a Circular Economy for Plastics

whitePaper | April 11, 2022

Chemical recycling is the only way to recycle large volumes of flexible plastics packaging and other mixed polyethylene/polypropylene into food grade PE/PP recycled content. Once operating at industrial scale, chemical recycling has the potential to recycle post-consumer flexible plastics “in practice and at scale».
