The Changzhou Waste Acid Resource Comprehensive Utilization Base operated by Yongbao Environmental focuses on the harmless disposal and resourceful utilization of waste acid and aluminum slag. The base has developed an energy-efficient, low-carbon, eco-friendly, and highly efficient process chain for treating and recycling waste acid and aluminum slag from over 10 industries including metal surface treatment and mechanical manufacturing. Currently, Yongbao Environmental is able to process 215,000 tonnes of waste acid and aluminum slag and convert them into approximately 220,000 tonnes of water treatment agents each year. The base holds an 80% market share in hazardous waste disposal and utilization in Changzhou and surrounding areas, serving over 2,000 customers. This initiative not only reduces environmental pollution from waste but also promotes the efficient recycling of resources.
