BaoLi Environment, a Zhejiang-based company that specializes in recycling organic solid waste from urban perishables and municipal waste dregs, has reached the level of recycling 250,000 tons of waste vegetables a year at one of its demonstration sites. The resulting wastewater and residue were processed into 15,000 tons of organic fertilizer and 6,000 tons of feed.

This efficient use of perishable garbage, urban dregs and abandoned vegetable leaves can help save soil resources.

The company’s low-temperature hydrolysis process can also fully decompose the excrement produced by pig farms, chicken farms and cattle farms, before processing the resulting solid and liquid waste into agricultural organic fertilizer, Cao Yun, head of engineering at BaoLi Environment, said at the forum.

China’s comprehensive utilization of resources has entered a new stage. The utilization process must be clean, without any secondary pollution, and there is also an emphasis on how to select and use waste scientifically, said Zhou Changyi, former director general of the Department of Energy Conservation and Resources Utilization of the Ministry of Industry and Information Technology.

With the increasing value of energy conservation and environmental protection in the national economy, the goal of a waste-free city in the future will inspire more innovation, experts said at the forum.
