This breakthrough makes it possible to produce <strong>fully recycled stainless steel and copper<\/strong>, with guaranteed traceability and a <strong>near-zero carbon footprint<\/strong>. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why is it so important?<\/h2>\n\n\n\n<p>Each year, Switzerland imports approximately <strong>140,000 tons of high-performance steel<\/strong>, which represents a significant dependence and a high environmental burden. With these solar furnaces, it is possible to change that model for a <strong>circular, local and emission-free production<\/strong>, being able to reduce the carbon footprint by a <strong>factor of 165<\/strong> compared to conventional processes. <\/p>\n\n\n\n<p>In addition, the furnaces are part of a <strong><a href=\"https:\/\/inspenet.com\/en\/articulo\/green-metallurgy-sustainable-processes\/#toc_heading-5\" target=\"_blank\" rel=\"noreferrer noopener\">circular economy in the metallurgical sector<\/a><\/strong>, especially in regions linked to watchmaking, where high-quality steel and copper waste is abundant.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The future of steel production lies in the sun<\/h2>\n\n\n\n<p>The inauguration was supported by local authorities, energy experts, and strategic partners, underscoring the collaborative nature of the project. The success of these solar ovens opens the door to their <strong>replication in other countries<\/strong>, particularly those with high solar radiation and dependence on imported metals. <\/p>\n\n\n\n<p><strong>Source: <a href=\"https:\/\/www.linkedin.com\/posts\/panatere_panatere-innovation-energiesolaire-activity-7381612397779759104-Gf8n?utm_source=share&amp;utm_medium=member_desktop&amp;rcm=ACoAAD-_ZkgB8cAZ4-bjJZ2jQozct7BLl_SXgfQ\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">PANATERE<\/a><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>PANATERE inaugurates two solar furnaces in La Chaux-de-Fonds that melt recycled steel with clean energy.<\/p>\n","protected":false},"author":10019,"featured_media":310521,"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-311092","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\/311092","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=311092"}],"version-history":[{"count":0,"href":"https:\/\/inspenet.com\/en\/wp-json\/wp\/v2\/noticias\/311092\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/inspenet.com\/en\/wp-json\/wp\/v2\/media\/310521"}],"wp:attachment":[{"href":"https:\/\/inspenet.com\/en\/wp-json\/wp\/v2\/media?parent=311092"}],"wp:term":[{"taxonomy":"categoria_noticias","embeddable":true,"href":"https:\/\/inspenet.com\/en\/wp-json\/wp\/v2\/categoria_noticias?post=311092"},{"taxonomy":"etiqueta_noticias","embeddable":true,"href":"https:\/\/inspenet.com\/en\/wp-json\/wp\/v2\/etiqueta_noticias?post=311092"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
