The Cambridge researchers found that used cement is an effective substitute for lime flux, which is used in steel recycling to remove impurities, and ultimately known as a waste product known as slag.<\/p>\n<p>By replacing lime with used cement, the end-product is recycled cement that can be used to make new concrete. The method is not said to add any significant costs to concrete or steel production, and \u201csignificantly\u201d reduces emissions from both concrete and steel, due to not needing lime flux. Recent tests carried out by the Materials Processing Institute, a partner in the project, showed that recycled cement can be produced at scale in an electric arc furnace (EAF). Eventually, this method could produce zero emission cement, if the EAF was powered by renewable energy.<\/p>\n<p>Scientists have been investigating substitutes for cement for over a decade, and have said that roughly half of the cement in concrete can be replaced with alternative materials, such as fly ash, but these alternatives need to be chemically activated by the remaining cement in order to harden. The cement made through this recycling process contains higher levels of iron oxide than conventional cement, but the researchers said this has little effect on performance. The Cambridge Electric Cement process has been scaling rapidly, and the researchers say they could be producing one billion tonnes per year by 2050, which represents roughly a quarter of current annual cement production.<\/p>\n<p>Source: <a rel=\"noopener\" href=\"https:\/\/www.letsrecycle.com\/news\/cambridge-electric-cement-a-miracle-in-transition-to-net-zero\/\">Reuters<\/a><\/p>\n<\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/environmental-news-en\/1-529\/\">Cambridge Electric Cement a \u2018miracle\u2019 in transition to net zero<\/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":[3801,3802,575,14639],"class_list":["post-130687","post","type-post","status-publish","format-standard","hentry","category-news","tag-cement","tag-concrete","tag-environmental-news-en","tag-furnace"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/130687","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=130687"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/130687\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/media?parent=130687"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/categories?post=130687"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/tags?post=130687"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
