That&#8217;s the promise of an Australian university turning used coffee grounds into a material that can be added to concrete to make it stronger and more sustainable, potentially lowering greenhouse gas emissions. Concrete production, which involves mixing sand and gravel with cement and water, is a major producer of greenhouse gases, responsible for around 7% of the world&#8217;s emissions, according to the United Nations.<\/p>\n<p>Researchers at Melbourne&#8217;s RMIT University heated coffee waste without oxygen, a process known as pyrolysis, to create a substance called biochar that can replace up to 15% of the sand used in concrete. The inclusion of the biochar makes the concrete 30% stronger and reduces the amount of cement needed by up to 10%, said lead researcher Rajeev Roychand.<\/p>\n<p>Millions of tons of used coffee grounds are produced globally and most are sent to landfills where they emit methane as they break down. Australia generates around 75,000 tons of waste coffee grounds a year and biochar made from this could replace up to 655,000 tons of sand in concrete because it is a denser material, Roychand said. Globally, coffee-waste biochar could replace up to 90 million tons of sand in concrete, he said. Food waste accounts for around 3% of Australia&#8217;s emissions, according to the government, and most could eventually be made into biochar, Roychand said.<\/p>\n<p>Source: <a rel=\"noopener\" href=\"https:\/\/www.reuters.com\/business\/environment\/australian-researchers-turn-morning-coffee-waste-into-greener-concrete-2024-05-22\/\">Reuters<\/a><\/p>\n<\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/environmental-news-en\/1-528\/\">Australian researchers turn morning coffee waste into greener concrete<\/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":[616,14630,3802,575],"class_list":["post-130648","post","type-post","status-publish","format-standard","hentry","category-news","tag-australia","tag-coffee-waste","tag-concrete","tag-environmental-news-en"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/130648","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=130648"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/130648\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/media?parent=130648"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/categories?post=130648"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/tags?post=130648"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
