We have expertise in designing and installing solid waste treatment and handling systems with a variety of applications. For instance, we designed, built and operated the first organic resources recovery centre at Siu Ho Wan in Hong Kong in 2018; a low level radioactive waste storage facility at Siu A Chau in Hong Kong; upgraded sludge dewatering systems at Tai Po, Yuen Long, Sai Kung and Shek Wu Hui sewage treatment works in Hong Kong; installed automated refuse collection and handling systems for residential developments in Hong Kong; and designed, installed and commissioned the sludge dewatering system for the Changqiao Water Works in Shanghai, mainland China. We have collaborated with engineers and manufacturers to design and improve applications utilising advanced waste minimisation technologies including recycling, anaerobic digestion, incineration and pelletising. In addition to solid waste handling systems, we have been investing in new systems tailored to the unique environment of Hong Kong. A pilot scheme for anaerobic co-digestion of food waste and sewage sludge has equipped us with up-to-date solid waste handling expertise and is expected to support full scale applications in future projects.
