Yiliang County 200-ton/day Municipal Solid Waste Low-Temperature Carbonization Project
The Yiliang Yishi Domestic Waste Biochemical Treatment Plant in Yunnan has a stable daily processing capacity of up to 200 tons. Since its operation began, it has processed over 90,000 tons of domestic waste, producing more than 40,000 tons of carbon powder. At the same time, it automatically sorts and recovers over 4,000 tons of various recyclable metals, glass, and sand and gravel materials.
