The innovation provides a simple and environmentally friendly way to recycle wind turbine blades to create useful products.<\/p>\n<p>Reporting in the journal, Resource, Conservation, and Recycling, the team of researchers cut the lightweight material that is commonly used in wind turbine blades, called glass fiber-reinforced polymer (GFRP), into approximately two inch-sized blocks. They then soaked the flakes in a bath of low-toxicity organic salt in pressurized, superheated water for about two hours to break down the material. They then re-purposed its components to make stronger plastics.<\/p>\n<p>In their work, the researchers soaked the blade material in a mild solution of zinc acetate, which is used in medicines, such as in throat lozenges and food additives. The mild solution allowed the researchers to recover glass fibers and resins in good condition which they then added directly to thermoplastics to produce strong composite materials with up to 70% of the recycled glass fiber materials. Moreover, the researchers were able to recover and reuse most of the catalyzing zinc acetate solution through simple filtration. When the researchers added the recycled material to nylon plastic and tested it, they found that the additional fibers made the nylon more than three times stronger and more than eight times stiffer. They also found that the recycled GFRP material can reinforce other plastics, such as polypropylene and the type of plastics used in milk jugs and shampoo bottles.<\/p>\n<p>Source: <a rel=\"noopener\" href=\"https:\/\/www.eurekalert.org\/news-releases\/1078562\">Eurek Alert!<\/a><\/p>\n<p><p>&nbsp;<\/p>\n<\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/environmental-news-en\/1-695\/\">Researchers recycle wind turbine blade materials to make improved plastics<\/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":[18441,575,694,1558],"class_list":["post-138836","post","type-post","status-publish","format-standard","hentry","category-news","tag-blades","tag-environmental-news-en","tag-plastic","tag-wind-turbine"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/138836","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=138836"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/138836\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/media?parent=138836"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/categories?post=138836"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/tags?post=138836"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
