The paper, published on Thursday in PLOS Biology, delves deeper into the practice known as bioleaching, or the use of living organisms to pull minerals from rock, soil and waste. This process is also sometimes called \u201cbiomining.\u201d The researchers from Canada\u2019s University of Waterloo found that cyanobacteria \u2014 a kind of bacteria that gets energy from light, like plants \u2014 helped bind trace metals in mine waste into more easily retrievable minerals.<\/p>\n<p>As an added bonus, these techniques could help cut a sizable minority of carbon emissions from mining, the researchers wrote. By doing so, they could help increase efficiency and reduce ecological damage from surging production of the array of minerals expected to be essential in the move to electrify transportation and the grid, the study said. That push for electrification has long rested on a difficult paradox: Achieving the large-scale climate benefits of getting off of fossil fuels requires a huge uptick in mining \u2014 one of the most polluting sectors worldwide.<\/p>\n<p>Mining is heavily polluting because it requires crushing rock to reveal ores within. These then must be pulled from the debris, often using dangerous heavy metals, in particular mercury. Mercury is dangerous for the same reason it\u2019s effective: It binds very effectively to metals, creating blobs of ore and mercury that can then easily be refined down into pure metal. That stickiness, however, also means it binds into animal tissues, reaching greater and more toxic concentrations as you move up the food chain.<\/p>\n<p>Source: <a rel=\"noopener\" href=\"https:\/\/thehill.com\/policy\/equilibrium-sustainability\/3975684-microbes-can-mine-metals-from-toxic-waste-while-fighting-climate-change-study\/\">The Hill<\/a><\/p>\n<\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/environmental-news-en\/2-357\/\">Microbes can \u2018mine\u2019 metals from toxic waste \u2014 while fighting climate change: study<\/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":[575,2108,1180,8145],"class_list":["post-113810","post","type-post","status-publish","format-standard","hentry","category-news","tag-environmental-news-en","tag-metal","tag-microbes","tag-toxic-waste"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/113810","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=113810"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/113810\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/media?parent=113810"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/categories?post=113810"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/tags?post=113810"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
