The solution responds to concerns that, as the most widely used plastic in the world, polyethylene contributes heavily to plastic waste in landfills and causes issues for the environment and ecological health.<\/p>\n<p>Existing chemical recycling processes for polyethylene waste operate at temperatures higher than 400\u00b0C and result in complex production compositions. As a chemical feedstock, ethylene can be further processed into various industrial and everyday products, and the antiseptic and antibacterial properties of propionic acid are said to increase its demand on the market.<\/p>\n<p>It is hoped that the progress made by the team will overcome roadblocks regarding environmental damage and energy-intensive processes, as well as take steps towards circularity. The photocatalysis solution is anticipated to be of use in further scientific research, waste management, and chemical manufacturing. In related news, chemists at the University of Li\u00e8ge are producing new polyurethane using CO2 as a chemical source \u2013 a move expected to drive the development of more easily recyclable plastics.<\/p>\n<p>Source: <a rel=\"noopener\" href=\"https:\/\/packagingeurope.com\/news\/university-of-adelaide-uses-light-to-accelerate-conversion-of-pe-waste-into-valuable-chemicals\/10808.article\">Packaging Europe<\/a><\/p>\n<\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/environmental-news-en\/5-455\/\">University of Adelaide uses light to accelerate conversion of PE waste into valuable chemicals<\/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":[1550,575,12721,445],"class_list":["post-119733","post","type-post","status-publish","format-standard","hentry","category-news","tag-chemicals","tag-environmental-news-en","tag-polyethylene","tag-waste"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/119733","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=119733"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/119733\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/media?parent=119733"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/categories?post=119733"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/tags?post=119733"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
