It involves converting polycarbonate into its original building blocks in a process known as depolymerization. Key to this process is lignin, a major component of biomass which is now being recognized for its potential to at least partially replace fossil fuels in the production of plastics and other commercial products owing to its renewability, broad market, and low cost. It\u2019s also a major unwanted byproduct of the biofuel and pulp and paper industries, where the latter generates approximately 50\u201370 billion tons of lignin annually. Much of this lignin goes to waste.<\/p>\n<p>To make this process more sustainable, Chung and Ghorai used lignin instead of a fossil fuel-derived starting material as well as a metal-free catalyst. Lignin is a good alternative because its chemical structure is rich in functional groups that can react with carbon dioxide in the presence of a suitable catalyst.<\/p>\n<p>This reaction, which the researchers catalyzed using an organic molecule, produces cyclic carbonate, the building block or \u201cmonomer\u201d of polycarbonate. The second step, the polymerization of cyclic carbonate into polycarbonate, can be done at room temperature and normal atmospheric pressure \u2014 much milder conditions than those required for the conventional synthesis.<\/p>\n<p>Source: <a rel=\"noopener\" href=\"https:\/\/www.advancedsciencenews.com\/new-plastic-recycling-method-captures-carbon\/\">Advanced Science News<\/a><\/p>\n<\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/environmental-news-en\/5-524\/\">New plastic recycling method captures carbon<\/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":[14386,575,1187],"class_list":["post-130146","post","type-post","status-publish","format-standard","hentry","category-news","tag-depolymerization","tag-environmental-news-en","tag-lignin"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/130146","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=130146"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/130146\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/media?parent=130146"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/categories?post=130146"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/tags?post=130146"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
