The Digimelter electric arc furnace consumes 50 fewer kilowatt hours per metric ton than conventional systems. This saves roughly €7.5 million annually in electricity costs. The closed loop cooling system cuts water use by half. It recovers 24 megawatts of thermal energy for reuse. No workers stand on the production floor. Machine learning algorithms control all operations. The European Union funded Custard project converts CO₂ into sodium bicarbonate, eliminating over 13,000 metric tons of emissions yearly.
