Differentiation of development technology
◦ Development of recycling technology for process catalysts from the perspective of resource circulation → Reduce the use of natural resources, increase the efficiency of resource use, Strengthening the cost and quality competitiveness of the national manufacturing industry
◦ Hydro smelting (≥600 ℃), which is more energy efficient than existing dry smelting (≥1500 ℃)
Carbon reduction / energy reduction / reuse of melting agent
◦ Significantly reduces environmental pollutant emissions by using leaching agents that exclude acidic substances
◦ Contributes to reducing energy consumption and greenhouse gases compared to disposal and landfill
