Core business and operations

According to the company’s disclosures, CDT operates along two primary business lines: sewage treatment systems and sewage treatment services. The systems business involves environmental engineering projects in which CDT designs and delivers sewage treatment installations for customers. The services business focuses on operating and maintaining treatment facilities and related infrastructure. Through these activities, CDT participates in water environmental protection, municipal sewage treatment, and associated infrastructure projects.

The company reports that it has completed more than 150 plants across China, reflecting a project-based business model centered on infrastructure construction and operation. CDT describes itself as a recognized brand in China’s waste treatment market and notes that it collaborates with industry leaders, environmental experts, and stakeholders to develop and implement advanced waste treatment solutions.

Market focus and sector role

CDT operates within the broader waste management and water environmental protection industry. Its projects include sewage treatment plants and related pipeline and municipal infrastructure. The company highlights its participation in infrastructure and construction projects involving water, sewage treatment, roads, and pipelines, including cooperation with a subsidiary of a large state-owned construction group in China on projects in Fuzhou New Area. CDT also reports a strategic cooperation framework in Fujian Province that leverages extensive pipeline inspection data to support municipal pipeline inspection, dredging maintenance, and sewage treatment opportunities.

Through these relationships, CDT aims to use its government relations, brand position, and waste treatment expertise together with partners’ local experience and technical capabilities. The company states that such collaborations are intended to enhance its service platform, broaden market access, and strengthen its competitive position in regions such as South China and East China.

Expansion into green hydrogen and waste-to-energy

In addition to its established sewage treatment activities, CDT has announced a strategic growth initiative to enter the green hydrogen and waste-to-energy market. The company describes itself as an environmental company focused on urban and rural organic waste treatment and states that it is positioning to become a provider of urban and rural organic waste resource utilization solutions and clean energy.

CDT’s plan centers on using high-temperature gasification technology to convert organic waste into syngas, which can then be purified to produce hydrogen or used for other energy applications. The company reports a technical collaboration with the Guangzhou Institute of Energy Conversion, Chinese Academy of Sciences, and notes that a senior expert from this institute has been appointed as Chief Scientist for its new energy initiative. A subsidiary of CDT also participated in drafting the group standard "Technical Requirements for Waste-to-Hydrogen Based on High-Temperature Pyrolysis and Gasification," which was published by the China Association for Testing and Inspection.

CDT describes an "EPC engineering + long-term operation" business model for its waste-to-hydrogen projects, under which it expects revenue sources to include waste treatment service fees and potential sales of energy products such as green hydrogen, clean industrial steam, and grid-connected electricity. The company views this initiative as a strategic upgrade that connects demand for organic waste treatment with opportunities in the hydrogen energy market.

Project pipeline and backlog

The company’s public financial updates indicate that its revenues are closely tied to the timing and number of infrastructure projects. CDT has disclosed backlogs that include projects such as the Sichuan Anya Project, the Xinjiang Project, and Phase VI of the Guankou Project, with combined tentative contract values in the tens of millions of U.S. dollars. These projects relate to its sewage treatment systems business and reflect ongoing work in multiple regions of China.

CDT has also reported that it is in the process of acquiring additional sewage treatment system projects and that it evaluates new opportunities in both its traditional environmental engineering activities and its emerging new energy initiatives. The company notes that project activity can be affected by macroeconomic conditions in the People’s Republic of China, including slowdowns that may delay infrastructure investments.
