Data from the UN\u2019s Global e-waste monitor report published last year found that worldwide generation of e-waste is rising five times faster than documented e-waste recycling. A record 62 billion kg of e-waste was generated globally in 2022 \u2013 up 82% from 2010, and on track to rise a further 32% (to 82 billion kg) in 2030.<\/p>\n<p>To combat this \u2018tsunami\u2019 of e-waste, a team at Virginia Tech has been researching a new class of recyclable circuit materials to replace traditional circuit board plastics. Combining expertise from disparate fields, Michael Bartlett, associate professor of mechanical engineering, and Josh Worch, assistant professor of chemistry, have created new circuits that are recyclable, electrically conductive, reconfigurable, self-healing after damage and as strong as the material they replace.<\/p>\n<p>The approach they took in creating the circuit board was to start with a vitrimer, a dynamic, versatile polymer material that can be reshaped and recycled. This material was combined with droplets of liquid metal to conduct the electric current. At its end of life, the circuit board can be easily recycled in multiple ways. The circuit boards can also be deconstructed using alkaline hydrolysis. This allows for key components such as the liquid metal and LEDs to be recovered. Further research will look into fully reusing all components of the conductive composites in a closed-loop process.<\/p>\n<p>Source: <a rel=\"noopener\" href=\"https:\/\/eandt.theiet.org\/2025\/06\/04\/recyclable-self-healing-circuit-boards-could-tackle-global-e-waste-crisis\">E and T<\/a><\/p>\n<p><p>&nbsp;<\/p>\n<\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/environmental-news-en\/6-712\/\">Recyclable, self-healing circuit boards could tackle global e-waste crisis<\/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":[22,1],"tags":[14422,575,4065,655],"class_list":["post-140746","post","type-post","status-publish","format-standard","hentry","category-news","category-yleinen","tag-circuit-board","tag-environmental-news-en","tag-ewaste","tag-yleinen"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/140746","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=140746"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/140746\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/media?parent=140746"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/categories?post=140746"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/tags?post=140746"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
