Guangzhou Zengcheng Sludge Carbonization Project

Dingjiu Environment's landmark project inside the Zhongxin下沉式再生水厂 in Zengcheng, Guangzhou. Using integrated sludge continuous drying and carbonization technology, it achieves on-site sludge resource recovery with low operating costs and near-zero emissions. The project processes 35 tons/day and was commissioned in January 2025. Learn how Dingjiu Environment solves municipal sludge challenges through technological innovation.

The Guangzhou Zengcheng Sludge Carbonization Project is a benchmark demonstration project built by Hunan Dingjiu Energy & Environment Technology Co., Ltd. using its fully proprietary "integrated sludge continuous drying and carbonization technology," located inside the Zhongxin下沉式再生水厂 in Zengcheng District, Guangzhou. As a core supporting project of the water plant, it aims to solve municipal sludge treatment challenges on-site and achieve green and low-carbon operation throughout the entire process. The project is constructed in two phases. Phase I with a capacity of 35 tons/day (actual system capacity can reach 40-45 tons/day) was officially put into commercial operation on January 1, 2025, marking the successful commercial implementation of Dingjiu Environment's new-generation technology in the sludge disposal domain of modern, high-standard environmental protection requirements in water plants.
