With recycling taking the centre stage in Europe&#8217;s decarbonisation ambitions, it is said to generate a large volume of dross, especially from the secondary aluminium production. Recovering metal, particularly aluminium, while complying with the increasingly strict environmental regulations, has therefore become a strategic priority rather than merely an operational necessity.<\/p>\n\n\n\n<p>Against this backdrop, advanced rotary furnace processing is emerging as one of the industry\u2019s most commercially viable solutions. AL Circle\u2019s report, <a href=\"https:\/\/www.alcircle.com\/specialreport\/1341\/aluminium-dross-processing-a-global-review\">&#8220;<mark style=\"background-color:#ffffff;color:#171390\" class=\"has-inline-color\">ALuminium Dross Processing: Generation, Recovery &amp; Strategic Roadmap<\/mark><\/a>&#8220;, shows how a company, ALTEK Europe, among the technology providers, is helping recyclers and secondary producers recover greater value from aluminium dross. These technologies not only help the recyclers and the secondary producers but also support Europe\u2019s wider circular economy objectives.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>The challenge: Recycling growth is reshaping Europe&#8217;s dross effective management<\/strong><\/h2>\n\n\n\n<p>The aluminium sector in Europe is now highly driven by the recycled aluminium market. But, unlike the primary producers, it is deemed that the secondary recycling process generates a good volume of dross, because of contaminated scrap, coatings, impurities and oxidation during remelting. With the rising recycling capacity in Europe, the complexity of effectively managing black dross and salt slag is increasing.<\/p>\n\n\n\n<p>Historically, this was considered a huge waste stream, but now it is being recognised as a valuable secondary resource, which is capable of yielding recoverable metal, reusable salts and alumina-rich materials. This recovery makes it highly beneficial for sectors like construction, refractory and ceramic applications. Therefore, the commercial focus has now shifted from disposal towards resource recovery.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Why does rotary furnace processing remain commercially relevant now?<\/strong><\/h2>\n\n\n\n<p>The aluminium dross, in today\u2019s time, is said to contain varying proportions of metallic aluminium, aluminium oxide, salts and other compounds. Through the mechanical recovery methods, white dross can often be processed, but due to higher oxide and salt content, the major technical challenge is seen in the management of black dross. This is exactly why, to demonstrate the commercial value, rotary furnace processing is still deemed to be highly relevant.<\/p>\n\n\n\n<p>The technology introduces aluminium dross into a rotary furnace together with sodium chloride and potassium chloride fluxes. Operating at temperatures typically between 800\u00b0C and 1,000\u00b0C, the process protects molten aluminium from further oxidation, improves metal coalescence and enables efficient recovery from material that mechanical separation alone cannot process effectively.<\/p>\n\n\n\n<p>Moreover, rotary furnace processing has become more than a recovery technology; it has become an important component of regulatory compliance, ESG performance and long-term competitiveness.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>The business case for ALTEK Europe\u2019s approach<\/strong><\/h2>\n\n\n\n<p>While the aluminium recycling industry in Europe continues to face the mounting pressure to recover more metal while reducing waste and meeting stricter environmental standards, ALTEK Europe is positioning itself as more than a furnace technology provider. The company provides solutions which are designed to improve the economics of dross processing by integrating metal recovery, salt recycling and resource efficiency within a single recovery ecosystem.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Innovation 1: AluSalt<\/h3>\n\n\n\n<p>This innovation marks one of the firm\u2019s most notable developments, enabling it to recover reusable salts and metallic products from rotary furnace residues. Within the conventional processing, salt slag used to be treated as a disposal challenge. But now, with the AluSalt technology, it can be converted into reusable resources that can re-enter the recycling process. The European FP7 ALUSALT project had successfully demonstrated pilot-scale recycling of salt cake for reuse within the aluminium recycling industry, reinforcing the commercial viability of this approach.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Innovation 2: Dry salt technologies<\/h3>\n\n\n\n<p>Another area where ALTEK Europe is advancing rotary furnace processing is through the development of dry salt technologies. Previously, the rotary furnace systems were always heavily dependent on the salt fluxes in order to improve metal separation, but high salt consumption increases operating costs while generating significant volumes of salt slag that require further treatment. ALTEK Europe\u2019s technology focuses on reducing salt consumption during dross processing, helping recyclers lower material usage without compromising recovery efficiency.<\/p>\n\n\n\n<p>Among the leading suppliers of integrated recovery systems, which combine aluminium recovery with near-complete salt recycling, ALTEK Europe has been identified as part of this. This is because these closed-loop systems reportedly achieve aluminium recovery rates above 99% and also enable recovered salts to be reused within the recycling process. By reducing dependence on virgin salt inputs and minimising waste generation, the technology supports both operational efficiency and Europe\u2019s wider circular economy objectives.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Creating value beyond aluminium recovery<\/strong><\/h2>\n\n\n\n<p>The commercial value of the technologies developed by ALTEK Europe for the aluminium recyclers extends beyond just recovering additional metals. With the integration of salt recovery into the recycling process, the industry operators are able to reduce fresh salt purchases, minimise disposal costs and improve compliance with increasingly stringent landfill regulations. Moreover, this approach also allows them to have a smooth transition towards near-zero-waste processing.<\/p>\n\n\n\n<p>Now, the recyclers in the industry, instead of viewing salt slag as an unavoidable by-product, are able to recover reusable sodium chloride and potassium chloride while generating alumina-rich materials that offer opportunities for further industrial utilisation. The result is improved resource efficiency alongside stronger environmental performance.<\/p>\n\n\n\n<p>Technologies such as ALTEK Europe\u2019s AluSalt process and integrated recovery systems demonstrate how innovation is helping the industry move beyond traditional waste management. By recovering metallic aluminium, recycling process salts and reducing landfill dependence, these solutions support a more resource-efficient aluminium value chain while strengthening Europe\u2019s transition towards circular manufacturing.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Conclusion<\/strong><\/h2>\n\n\n\n<p>The focus of Europe\u2019s aluminium recycling industry is no longer on recovering metal from dross, but rather on recovering maximum value from every output generated during the process. ALTEK Europe, through innovations such as AluSalt, dry salt technologies and integrated recovery systems, is aiding aluminium recyclers to transform rotary furnace processing into a more efficient, circular and commercially sustainable operation.&nbsp;<\/p>\n\n\n\n<p>As Europe&#8217;s demand for recycled aluminium continues to rise, technologies that maximise resource recovery while reducing environmental impact are likely to play an increasingly important role in shaping the next generation of aluminium recycling.
