An innovative partnership between Speira and GHI Smart Furnaces aims to redefine sustainability standards in the aluminium industry. Together, they aim to achieve an unprecedented reduction of 1.5 million tonnes of CO2 emissions annually. This ambitious initiative represents a pivotal moment in pursuing environmental stewardship within the sector.
The focal point of this partnership is the transformation of Speira’s Rheinwerk plant in Germany, propelled by a substantial €40 million investment. This strategic move enhances operational efficiency and positions the plant as a global leader in green technology innovation.
Speira's unwavering commitment to sustainability is evident across its operations. With eleven recycling and production sites in Germany and Norway, Speira processes approximately 650,000 tonnes of aluminium each year. This extensive network, which includes the world's largest aluminium rolling mill, Alunorf, highlights Speira's capability and ambition to lead in aluminium recycling.
The Rheinwerk project is a cornerstone of Speira's strategy to become Europe's premier aluminium recycler. Over the past two decades, Speira has made substantial investments in recycling capacities, including establishing Europe's most advanced sorting plant for used beverage cans (UBC). The new furnace, designed and manufactured by GHI, is set to be operational by early 2026. This major investment aims to enhance recycling efficiency and reduce environmental impact, reinforcing Speira's leadership in sustainable aluminium practices.
The enduring and fruitful collaboration between Speira and GHI on numerous projects highlights their mutual commitment to a sustainable future. GHI’s state-of-the-art furnace technology aligns with Speira’s objectives of lowering carbon emissions and promoting the circular economy.
Iñigo Guinea, CEO of GHI Smart Furnaces, said, “The Speira partnership exemplifies our commitment to turning our purpose into reality: empowering our customers to achieve their sustainability goals. Our Smart Multi-chamber Furnace will be pivotal in reducing Speira’s environmental footprint and advancing the circular aluminium economy in Rheinwerk.”
The furnace efficiently handles contaminated scrap by optimising energy usage. Its multi-chamber design enables simultaneous decontamination and melting processes. Utilising the organic components within the charge maximises energy efficiency. This innovative method improves recycling efficiency and significantly reduces CO2 emissions.
The Rheinwerk project features an Autonomous Charging Machine that revolutionises the loading process with advanced sensors and robotics. This system ensures precise metal charging, reduces loading time and heat loss, and boosts overall productivity. Automating the process enhances safety and extends the furnace’s lifespan by protecting its refractory lining from wear and tear.
