Thanks to a biological technology known as biodiscs, the final sludge contains a specific mixture of organic matter, metals, phosphorus and nitrogen, an ideal composition for its transformation into <strong>activated carbon<\/strong>, an essential matrix for <strong>conducting <a href=\"https:\/\/inspenet.com\/en\/news\/scientists-make-lithium-batteries-that-breathe-co2-more-efficient-and-sustainable\/\" target=\"_blank\" rel=\"noreferrer noopener\">energy in batteries<\/a><\/strong>. <\/p>\n\n<p>The residue, initially foul-smelling and pasty, is <strong>dried and pulverized<\/strong>, treated with potash to make it more porous and subjected to pyrolysis at <strong>800 \u00b0C<\/strong>, converting it into an electrochemically active carbon. The carbon is then <g id=\"gid_2\">mixed with sulfur in a ball mill<\/g>, generating a compound in which the sulfur is trapped in the matrix. The material is then ready to be incorporated into the electrodes of a battery.  <\/p>\n\n<h2 class=\"wp-block-heading\">Why is this so important?<\/h2>\n\n<p>Because it turns a problem into a solution with a <strong>double environmental benefit<\/strong>. Instead of seeing sewage sludge as simply a worthless and costly waste to manage, it can now be seen as <strong>the basis for making <a href=\"https:\/\/inspenet.com\/en\/news\/sodigreen-drives-development-of-more-sustainable-sodium-batteries\/\" target=\"_blank\" rel=\"noreferrer noopener\">more sustainable batteries<\/a>.<\/strong> <\/p>\n\n<p>Unlike other organic wastes (such as olive shells or pits) that are already used for compost or energy, sludge had no noble use and its reuse as a battery base represents an opportunity for both waste management and the energy industry.<\/p>\n\n<p><strong>Source: <a href=\"https:\/\/www.uco.es\/ucci\/es\/noticias-gen\/item\/5272-lodo-depuradora-bateria-carbon-activado\" target=\"_blank\" rel=\"noreferrer noopener\">University of Cordoba<\/a><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>IQUEMA researchers create a conductive material for sulfur batteries from sludge generated in a treatment plant in C\u00f3rdoba.<\/p>\n","protected":false},"author":10019,"featured_media":307645,"menu_order":0,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false,"_bbp_topic_count":0,"_bbp_reply_count":0,"_bbp_total_topic_count":0,"_bbp_total_reply_count":0,"_bbp_voice_count":0,"_bbp_anonymous_reply_count":0,"_bbp_topic_count_hidden":0,"_bbp_reply_count_hidden":0,"_bbp_forum_subforum_count":0,"footnotes":""},"categoria_noticias":[13026,13044],"etiqueta_noticias":[],"class_list":["post-307717","noticias","type-noticias","status-publish","has-post-thumbnail","hentry","categoria_noticias-energy","categoria_noticias-new-energies"],"acf":[],"_links":{"self":[{"href":"https:\/\/inspenet.com\/en\/wp-json\/wp\/v2\/noticias\/307717","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/inspenet.com\/en\/wp-json\/wp\/v2\/noticias"}],"about":[{"href":"https:\/\/inspenet.com\/en\/wp-json\/wp\/v2\/types\/noticias"}],"author":[{"embeddable":true,"href":"https:\/\/inspenet.com\/en\/wp-json\/wp\/v2\/users\/10019"}],"replies":[{"embeddable":true,"href":"https:\/\/inspenet.com\/en\/wp-json\/wp\/v2\/comments?post=307717"}],"version-history":[{"count":0,"href":"https:\/\/inspenet.com\/en\/wp-json\/wp\/v2\/noticias\/307717\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/inspenet.com\/en\/wp-json\/wp\/v2\/media\/307645"}],"wp:attachment":[{"href":"https:\/\/inspenet.com\/en\/wp-json\/wp\/v2\/media?parent=307717"}],"wp:term":[{"taxonomy":"categoria_noticias","embeddable":true,"href":"https:\/\/inspenet.com\/en\/wp-json\/wp\/v2\/categoria_noticias?post=307717"},{"taxonomy":"etiqueta_noticias","embeddable":true,"href":"https:\/\/inspenet.com\/en\/wp-json\/wp\/v2\/etiqueta_noticias?post=307717"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
