Waste-to-Energy Facility Delivered

Date：2024-02-19

Recently, COOEC's Zhuhai site completed the delivery of all 17 electromechanical modules of Hong Kong's Integrated Waste Management Facilities (IWMF) Phase 1. The project is the world's first waste-to energy facility with a modular design and integrated construction.

The IWMF Phase 1 is the first integrated solid waste management facility invested by the Environmental Protection Department of the Hong Kong SAR for the treatment of municipal solid waste. It adopts advanced incineration as the core treatment technology as well as fully automatic control of waste incineration, efficient heat energy utilization, and other advanced technologies. With an innovative deep recycling process of tail gas, it effectively improves energy conservation and environmental protection.

COOEC's Zhuhai site was contracted to build the 17 key modules for the project, including 6 boiler modules, 6 flue gas treatment systems, and 5 pipe gallery modules with a total weight of 50,000 tonnes. The modules consist of over 110,000 structural components and 270,000 equipment parts. The steel structures and their equipment are connected and fixed with nearly 2 million bolts.

For the first time in the world, the project's large modules were built with all bolt connection construction method, innovative technologies such as integrated construction and management involving various specialties etc., which significantly improved the performance of digital and visualized construction and the efficiency of project management. The construction period was shortened by 20%, and the dimensional accuracy error was controlled within 5 millimeters, reaching the industry's top level.

The IWMF Phase 1 will have a treatment capacity of 3,000 tonnes per day, produce about 480 million kilowatt-hours (kWh) of electricity per year, and reduce carbon dioxide emissions by 440,000 tons every year. It will effectively alleviate Hong Kong's demand for municipal solid waste landfills.
