HSB\u2019s Laboratories for Circular Economy ensured that the waste was ground up, washed, and separated from unsuitable materials using float-sink-separation and near-infrared technology.<\/p>\n<p>In order to be further processed for 3D printing, a strand of plastic must apparently be \u2018round and consistent in diameter over its entire length, with a smooth surface\u2019. So far, a grey plastic strand, about two millimetres thick, has been used directly as a filament in a commercial 3D printer. Among the first successfully printed packaging components are caps. Following the results of the feasibility study, Fraunhofer IFAM and HSB are working to optimize the production process and generating new ideas for follow-up projects.<\/p>\n<p>Source: <a rel=\"noopener\" href=\"https:\/\/packagingeurope.com\/news\/polypropylene-packaging-waste-recycled-into-filaments-for-3d-printing\/12699.article\">Packaging Europe<\/a><\/p>\n<\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/environmental-news-en\/2-695\/\">Polypropylene packaging waste recycled into filaments for 3D printing<\/a> appeared first on <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\">Vastuullisuusuutiset.fi<\/a>.<\/p>\n","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":[575,11915,18494],"class_list":["post-138925","post","type-post","status-publish","format-standard","hentry","category-news","tag-environmental-news-en","tag-packaging-waste","tag-polypropylene"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/138925","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/comments?post=138925"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/138925\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/media?parent=138925"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/categories?post=138925"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/tags?post=138925"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
