SENT Landfill Gas Utilisation Project commissioned (with photos)
Speaking at the commissioning ceremony, the Secretary for the Environment, Mr Wong Kam-sing, remarked that the successful launch of the project marks another key milestone in waste-to-energy development in Hong Kong. It is also another excellent example of green partnership between the Government and the energy sector in putting landfill gas to beneficial use.
Mr Wong said that the project helps reduce the use of fossil fuel in town gas production and cut emission of greenhouse gases, which contributes to combating climate change.
To combat climate change, the Government published Hong Kong's Climate Action Plan 2030+ in January this year, outlining the Government's longer-term action in combating climate change and setting out a new target to reduce Hong Kong's carbon intensity by 65 per cent to 70 per cent by 2030 compared with the 2005 level. To achieve the target, among other things, the Government is going to take the lead to optimise the introduction of renewable energy. Hong Kong has already embarked to capture and put to use the energy derived from waste treatment and is on a committed path to turn waste into energy.
Landfill gas, which contains mainly methane, is a form of renewable energy. Prior to the commissioning of the project, LFG generated at the SENT Landfill was used only for generating electricity to meet on-site electricity demands and as a fuel for heating use in its leachate treatment facilities.
In 2014, the contractor of the SENT Landfill, Green Valley Landfill Limited signed an agreement with Towngas to build the LFG Management (Reprocessing) Facilities at the SENT Landfill. Under the agreement, a 12-kilometre pipeline was built to convey the treated surplus LFG to the Towngas Offtake Station at Tseng Lan Shue, where the treated gas will be blended with town gas for injection into the Towngas supply grid for use.
The project increases the beneficial use of surplus LFG in the SENT Landfill to help reduce the emission of greenhouse gases. It is expected that emissions of carbon dioxide can be reduced by about 56 000 metric tonnes annually.
In addition to the SENT Landfill, the West New Territories Landfill and the North East New Territories (NENT) Landfill have also been utilising landfill gas to produce energy for office and facilities uses on-site. Also, the landfill gas utilisation project at the NENT Landfill was commissioned in 2007 in collaboration with Towngas to deliver processed surplus landfill gas to Towngas' production plant in Tai Po as an alternative energy source. In 2016, Alice Ho Miu Ling Nethersole Hospital in Tai Po introduced the use of landfill gas to its new Combined Heat and Power plant for power generation and heating. It became the first hospital in Hong Kong to adopt such an environmentally friendly system.
Also officiating at today's ceremony were the Managing Director of Towngas, Mr Alfred Chan, and the Country CEO of Veolia Hong Kong, Mr Joe Zorn.
