This project is divided into two phases. The phase I project is for 15t/h steam, which has been put into operation on November 6, 2021. The phase II project has been under acceptance. It is estimated that the project will consume 90,000 tons of agricultural and forestry waste, provide 225,000 tons of steam, and produce 30,000 tons of biomass charcoal annually. It can replace 40,500 tons of standard coal, representing a reduction of CO2 emissions by 107,700 tons annually. The emission of boiler tail gas can meet the emission standards of natural gas boilers. All biochar will be sold as carbon products. There is no emissions of tar, sewage or ash for the entire system.
