Stemin is today one of the European leaders in the production of Ingots & RSI <\/strong>(Remelted Secondary Ingots), in secondary and semi-primary alloys.
Within FECS Group<\/strong>, which has a total production capacity of 100,000 tonnes per year, Stemin<\/strong> stands out for its integrated industrial model<\/strong>, combining direct ownership of secondary raw materials, innovative smelting processes<\/strong> and high value-added production flexibility<\/strong>. <\/p>\n

The alloy production process relies on two highly efficient smelting lines<\/strong>, one of which is based on a proprietary IT\/EU patent<\/strong>. This patented technology enables the direct melting<\/strong> of metal turnings from industrial scrap without the use of sodium chloride<\/strong>, significantly minimising the environmental impact of the entire process.<\/p>\n

The raw material used in smelting is supplied by the company\u2019s internal division specialised<\/strong> in metal waste recovery<\/strong> and valorisation<\/strong>, ensuring continuous supply, full traceability and controlled metallurgical quality.<\/p>\n <\/div>\n \n \n <\/div>\n\n

Energy sustainability: a concrete commitment to responsible production<\/h3> <\/div>\n\n
\n

The entire smelting cycle is powered by oxy-combustion through a dedicated oxygen pipeline<\/strong>, completely replacing the need for road transport via tankers. This ensures greater operational safety<\/strong>, supply continuity<\/strong> and energy autonomy<\/strong>.<\/p>\n

The use of oxygen reduces methane consumption<\/strong> and, as a result, direct atmospheric emissions<\/strong>, improving the overall energy efficiency of the process.<\/p>\n

As part of its environmental sustainability strategy, the company operates a photovoltaic system<\/strong> that supplies around 60% of the site\u2019s total electricity demand<\/strong> through self-generation.
This significantly reduces indirect emissions<\/strong> and makes a tangible contribution towards achieving decarbonisation goals.<\/p>\n <\/div>\n \n \n <\/div>\n\n

Custom production and certified carbon footprint<\/h3> <\/div>\n\n
\n

Stemin supplies secondary<\/strong> and semi-primary alloys<\/strong> with customised<\/strong> compositions, developed according to the client\u2019s technical specifications and application requirements. Direct access to raw materials allows for flexible and prompt handling of custom orders<\/strong>, while ensuring consistent quality and maximum reliability. <\/p>\n

Each alloy can be provided with a Carbon Footprint Declaration, calculated using a Systematic Approach (SA) model in accordance with ISO 14067:2018 and certified by Bureau Veritas Italia S.p.A. This system enables clients to integrate the materials into sustainable supply chains, aligned with ESG criteria<\/strong> and Life Cycle Assessment<\/strong> (LCA) methodologies<\/strong>.<\/p>\n <\/div>\n \n \n <\/div>\n\n

Traceability, compliance and visibility on international markets<\/h3> <\/div>\n\n
\n

All semi-finished products manufactured by Stemin comply with ROHS, REACH<\/strong> and Conflict Minerals<\/strong> regulations. Material traceability <\/strong>is ensured through the International Material Data System (IMDS)<\/strong>, widely adopted in regulated and technically complex sectors. <\/p>\n

To ensure transparent and reliable supply conditions, even over medium to long-term horizons, Stemin<\/strong> has, since 2012, registered the FECS Group brand<\/strong> with leading commodity exchanges: the London Metal Exchange<\/strong>, the NASAAC<\/strong> Index (North American Special Aluminium Alloy Contract) and the Shanghai Stock Exchange<\/strong> \u2014 making it one of the first European producers in the sector to adopt this approach.<\/p>\n
