In 2021, the rising coal price broke through historical record, and low-price coal could not be purchased in local market in China.
To pursue this challenge, Zouping power plant looked for an opportunity to use non-coal fuel as raw materials in the power plant and found that characteristics and prices of some industrial wastes such as activated carbon in Zouping area are appropriate for burning. Trial burning of mixed coal and solid waste was conducted in a boiler to find appropriate types and amounts of solid wastes as well as blending ratios before extending to all boilers for mixed combustion test.

This conserved raw coal from burning and facilitated activated carbon disposal 9,337 tons in 2022. Moreover, in terms of social benefit, this enhanced customer satisfaction owing to positive contribution to guarantee the heat and power supply at high coal price condition as well as improved community satisfaction from facilitating industrial waste management, especially activated carbon in the area. Apart from those, the Company also earned economic benefit from saving coal burning cost and additional income from fly ash selling due to increasing of fly ash yield USD 5,775,468 as well as increased business agility and flexibility on high coal price situation.
