The same scientists have now demonstrated that the method can be used to address flexible foam polyurethane in collaboration with Plixxent A\/S, Dan-Foam Aps, and the Danish Technological Institute as part of the Danish RePURpose consortium.<\/p>\n<p>Researchers have broken down approximately one and a half kilos of foam mattresses, retrieved its major components, and used one of them, polyol, as a raw material in a new piece of mattress. The scientists replaced 64% of the mattress without compromising quality by using \u201cfresh\u201d polyol, which is majorly produced from crude oil, with polyol extracted from the old mattress. Researchers have also illustrated that the method can be repeated many times. In other words, the polyol can be extracted and reused from polyurethane foam.<\/p>\n<p>This advances us one step closer to a circular economy for flexible PU foam. It is also urgently needed. Since it is difficult to recycle, the vast majority of global PU waste is disposed of in landfills. Because PU cannot be melted, it cannot be molded into new products like many other plastics. In 2021, the global PU market was 24.7 million tons, and it is anticipated to reach 29 million tons by 2029. Flexible PU foam used in mattresses accounts for approximately 30% of the market.<\/p>\n<p>Source: <a rel=\"noopener\" href=\"https:\/\/www.azocleantech.com\/news.aspx?newsID=33802\">Azo Cleantech<\/a><\/p>\n<\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/environmental-news-en\/2-374\/\">Recycling of Polyurethane Foam Takes a Step Forward<\/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":[575,10924,764],"class_list":["post-115859","post","type-post","status-publish","format-standard","hentry","category-news","tag-environmental-news-en","tag-polyurethane-foam","tag-recycling"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/115859","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=115859"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/115859\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/media?parent=115859"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/categories?post=115859"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/tags?post=115859"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
