Landfill gas utilization projects: Shuen Wan Landfill (SWL), The Northeast New Territories (NENT) and the South East New Territories (SENT) landfill gas production facilities(SWL commenced operation since 1999, NENT commenced operation since 2007 , SENT commenced operation since 2017)
For town gas production, Towngas switched from coal/heavy oil to naphtha in the 1970s and harnessed renewable landfill gas since 1999. Since 2006, they have been using more natural gas in their fuel mix to reduce greenhouse gas (GHG) emissions and improve air quality. Through capturing and utilizing landfill gases from the SWL, NENT and SENT landfills, methane naturally generated from these sites is converted into renewable energy that replaces naphtha consumption or for direct use at customers’ premises. In addition, Towngas issued their first green bond in 2017 to support waste to energy projects in both HK and mainland China.
The NENT landfill gas utilisation project is one of the largest examples of "green" energy recovery and reuse in the world. It not only provides a new source of renewable energy, reducing the use of fossil fuels in our town gas production, it also significantly reduces the emission of greenhouse gases, thus helping to improve air quality in Hong Kong. SENT is one of the largest energy conservation and emission reduction environmental projects in Hong Kong, this waste-to-energy project is expected to reduce the emission of carbon dioxide by 56,000 tonnes per year, equivalent to the absorption of 2.4 million tree seedlings per year.
  • To tackle climate change and pave the way to a low carbon future, Towngas has made efforts to achieve a cleaner energy mix
  • By turning landfill gas into energy, Towngas aims to move towards a more sustainable fuel mix for gas production
Hydro-treated Vegetable Oil (HVO), Zhangjiagang, China: transforming inedible bio-grease feedstock into an advanced biofuel(On-going)
Using their patented technologies, Towngas established their first HVO plant for converting inedible bio-grease feedstock into advanced biofuels with International Sustainability & Carbon Certification (ISCC) in 2017. These fuels offer a significant reduction in GHG emissions compared to traditional fossil diesel. Additionally, they adopted the Zero Liquid Discharge system at this HVO production facility, which processes all effluent so that water can be reused and recycled.
In 2020, the facility produced around 88,000 tonnes of HVO, of which 90% was sold to Europe. The production of HVO saved around 259,000 tonnes of carbon emissions. Towngas is now exploring possible sites for new plants in other areas to extend the impact of transforming waste into high-value but low-carbon products, and are also planning to trial production of sustainable aviation fuel using biofuels in 2021.
  • Towngas aims to combat climate change, transit to a low-carbon future and achieve a circular economy through various innovative waste-to-energy/resource projects
  • They believe proactively reducing the carbon footprint in our products/services while at the same time creating business opportunities is the path to a sustainable future
Organic waste resource utilisation project, Suzhou, China: converting food waste into biogas, oil products, solid fuel and fertiliser(On-going)
Their first organic waste resource utilisation project was established in Suzhou city, Jiangsu province. Currently, the organic waste resource utilisation plant can process up to 500 tonnes of organic waste daily for conversion into natural gas, oil products, solid fuel and fertilisers. When construction of the second phase of this plant is completed in 2021, daily production capacity will increase to 800 tonnes. Moreover, wastewater is also treated and reused in the organic waste resource utilisation plant.
In 2020, it processed 92,000 tonnes of organic waste from nearby catering businesses that helped downstream customers to reduce 5,900 tonnes of carbon emissions. Towngas is also exploring additional food waste treatment projects in other cities to further enhance the impact of carbon reduction as well as circular economy and scale up the practicality of waste-to-resources/energy projects.
