The plant, scheduled to be commissioned in 2013, will be built by the Veolia-Leighton-John Holland joint venture to a design by engineer Arup and architect Vasconi.
The waste water sludge, mainly collected from Stonecutters Island Sewage Treatment Works, the largest treatment facility in Hong Kong, will be incinerated by fluidised bed incinerators. It will evaporate all of the water content in the sludge and burn 90% of the remaining solid component, hugely reducing the amount having to go to landfill.
According to Arup, the facility will provide Hong Kong with “an iconic landmark building that is respectful of its environment”.
The plan is for it to be self-sufficient, generating and exporting power to the electricity grid and processing sea water through a desalination plant. Rainwater will be collected for non-potable use, and waste water will be treated and re-used on site.
The plant will have a treatment capacity of 2,000 tonnes a day and will eventually produce over 20 MW of electricity. Construction will take 37 months.
The plant will have a visitor's gallery and a viewing platform for escorted visits for the public. There are also lecture theatres, an exhibition space, indoor spas, coffee and gift shops and outdoor gardens with foot baths and water features for public use.
In the center, the administrative building envelops the flue gas stacks and the top floor houses an observation deck to enjoy the views over Deep Bay and Shenzhen.
