Panatere's Solar Furnaces Revolutionize Steel Recycling
Panatere has pioneered a groundbreaking method to recycle steel waste, inaugurating two solar furnaces that melt and transform waste into a high-value stainless steel alloy. This innovative process significantly reduces CO2 emissions and fosters local autonomy in stainless steel production.
The larger furnace boasts a 138 m2 heliostat and a concentrator with 40 mirrors, while the smaller one has a 30 m2 heliostat and 460 mirrors. Together, they can reach temperatures up to 2000°C, sufficient to melt stainless steel. The primary waste sources are high-value waste from local watchmakers and biomedical companies.
The current CO2 emissions for producing stainless steel 1.4441 are about 6.8 kg per kg. Panatere's solar furnaces reduce this to a mere 41 g per kg. This remarkable reduction is achieved without using fossil energy carriers, minimizing the ecological footprint of the stainless steel production process. The project was made possible with the support of Haute Ecole Arc Ingénierie and the University of Franche-Comté.
Panatere's solar furnaces offer a sustainable solution for recycling steel waste. By providing local supply sources, companies can gain more autonomy and reduce their environmental impact. The future of stainless steel production looks brighter with this innovative, eco-friendly approach.
