Hong Kong will build a sewage sludge treatment plant with a capacity of hundreds of billions of tons this year


A US\$600 million sludge treatment plant will be completed in western New Territories, Hong Kong, by the end of 2013. It will handle sludge from 11 sewage treatment plants in Hong Kong. Upon completion, the plant will be able to process up to 2,000 tons of sludge per day, reducing the total amount of sludge in Hong Kong by 90% and greenhouse gas emissions by 260,000 tons annually. The plant's design, construction, and operation are handled by Veolia Environnement, selected by the Hong Kong SAR government through open tender, with a 15-year contract. The plant uses high-temperature incineration technology to ensure that sludge treatment meets the highest environmental requirements and emission standards.
A US$600 million sludge treatment plant is scheduled for completion in late 2013 in western New Territories, Hong Kong. Upon completion, this plant will handle sludge from 11 sewage treatment plants in Hong Kong. Once operational, the plant will process up to 2000 tons of sludge daily, reducing Hong Kong's total sludge volume by 90% and annual greenhouse gas emissions by 260,000 tons. Veolia Environnement was selected by the Hong Kong Special Administrative Region government through open tender to design, build, and operate the plant under a 15-year contract.
The plant uses high-temperature incineration technology to ensure that sludge treatment meets the highest environmental protection requirements and emission standards. It will also achieve comprehensive utilization of sludge disposal, closely integrating sludge treatment, power generation, seawater desalination, and sewage treatment. The heat energy generated during sludge incineration will be converted into electricity, fully meeting the facility's own power needs, with surplus electricity fed into the local community grid. Wastewater generated during daily operations will be recycled through an accompanying seawater desalination plant, with no wastewater discharged into the ocean.
