The company said it was an important step in establishing its \u201ccircular economy\u201d credentials. The licence for the pyroliser was granted by the Scottish Environment Protection Agency. The surplus is a by-product of the wastewater treatment process in the hatchery\u2019s recirculating aquaculture system (RAS) facility. It consists of organic and inorganic solids held in water. The process dries the sludge and turns it into inert biochar which is used as a fertiliser and soil improver, refining the structure and water retention in soils. This process also \u201clocks away\u201d carbon permanently.<\/p>\n<p>In the first stage, hatchery sludge, roughly 97% water, is treated by going through a filter belt. The water content is reduced to about 80% and the dry matter content is increased to about 20%. The next stage requires the license as it incorporates a pyrolysis unit which dries sludge at about 300\u00b0C, generating sludge pellets. These are then heated to 700\u00b0C without the presence of oxygen during a pyrolysis process. Heat is effectively absorbed and repurposed inside the system, increasing total energy efficiency.<\/p>\n<p>The end product is a biochar which is a material with a high stable carbon content. Bakkafrost Scotland\u2019s ambition for its RAS facilities is to reduce waste by 90 per cent, to use 100 per cent sustainable power and to reduce the water used in the process by 90 per cent. Hydro, solar, recycled material, and heat recovery systems will be used to reduce impact on the environment.<\/p>\n<p>Source: <a rel=\"noopener\" href=\"https:\/\/www.fishfarmermagazine.com\/2024\/09\/26\/new-system-will-turn-hatchery-waste-into-fertiliser\/\">Fish Farmer<\/a><\/p>\n<\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/environmental-news-en\/4-600\/\">New system will turn hatchery waste into fertiliser<\/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":[575,7560,16254],"class_list":["post-133977","post","type-post","status-publish","format-standard","hentry","category-news","tag-environmental-news-en","tag-fertilizer","tag-hatchery-waste"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/133977","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=133977"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/133977\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/media?parent=133977"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/categories?post=133977"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/tags?post=133977"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
