Ph.D. candidate Adam McNeeley and his advisor, Alumni Distinguished Professor Y. A. Liu, a member of the Macromolecules Innovation Institute, report their investigation of chemical recycling processes that remove additives, impurities, and colorants from polyethylene terephthalate, commonly referred to as PET. The processes can allow for a greater percentage of the plastic to be recycled than with the current mechanical recycling processes.<\/p>\n<p>PET is found in many everyday use items such as textiles, packaging, and bottles. Current recycling of it is primarily done via the mechanical process, which is limited to clean recycled materials and is mostly applied to plastic bottles. Plastic bottles only make up about 30% of its end use, and the other 70% is not generally being considered for commercial recycling. Prior to their study, most of the work related to the chemical depolymerization of PET focused only on the chemistry aspect. But this research provides a thorough assessment of thermodynamics, chemistry, purification, waste management and sustainable design of PET depolymerization processes.<\/p>\n<p>The research team created a complete simulation model of four depolymerization processes that quantify the mass and energy balances together with energy demand and carbon dioxide emissions, which is a quantitative foundation for industrial practitioners interested in its depolymerization to further develop sustainable depolymerization processes. Their work also suggests key areas for researchers to focus on in order to meaningfully advance plastic recycling and allow new recycling technologies to be commercially feasible.<\/p>\n<p>Source: <a rel=\"noopener\" href=\"https:\/\/phys.org\/news\/2024-05-chemical-recycle-common-plastic.html#google_vignette\">Phys.org<\/a><\/p>\n<\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/environmental-news-en\/2-525\/\">Researchers analyze how a chemical process could help recycle a common plastic waste<\/a> appeared first on <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\">Vastuullisuusuutiset.fi<\/a>.<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[22],"tags":[1197,575,5446],"class_list":["post-130563","post","type-post","status-publish","format-standard","hentry","category-news","tag-chemical-recycling","tag-environmental-news-en","tag-pet"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/130563","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/comments?post=130563"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/130563\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/media?parent=130563"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/categories?post=130563"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/tags?post=130563"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
