Biogas generated in sewage treatment process in Hong Kong

Biogas from digesters in the sewage treatment works in Sha Tin, Tai Po, Fan Ling, Yuen Long have been utilized for a number of purposes - in boilers for producing hot water for the digesters, in engine-driven blowers to provide compressed air for the sewage treatment process, and in engine-driven electric generators to provide electricity for the sewage treatment works.

An example is the 330 kW engine-driven electric generator in Shek Wu Hui Sewage Treatment Works, commissioned in 2006.
