Yongbao Environmental, a subsidiary of China Lesso, has made an innovative breakthrough in treating oil-containing waste by successfully developing anaerobic pyrolysis recovery technology. Compared to traditional incineration methods, this technology offers significant advantages, including lower energy consumption, cleaner combustion, zero dioxin emissions, heavy metal solidification, and safe utilization of pyrolyzed carbon residues. With an annual processing capacity of 70,000 tonnes of oil-containing waste, the system recovers 12,500 tonnes of raw oil for refining and reuse. This breakthrough promotes the harmless treatment, volume reduction, and efficient utilization of sludge while enabling resource recovery and energy self-sufficiency.
