Description
Singapore is committed to pursuing sustainable development and continues to invest in research and development in new technologies that demonstrate strong potential to improve energy efficiency and reduce the carbon footprint of our water treatment processes in the long term. For example, Singapore is exploring the use of ultra-permeable membranes, blue energy (e.g. pressure-retarded osmosis) and ceramic membranes to reduce energy consumption in the desalination process. Singapore is also exploring the use of aerobic granular sludge membrane bioreactor and membrane aerated biofilm reactor to work towards energy self-sufficient used water treatment plants.) Singapore is currently constructing an integrated solid waste treatment and used water reclamation facility, known as the Tuas Nexus, that leverages synergies in water, energy recovery and material handling between the two plants. Co-location of the plants maximises energy and resource recovery, and optimises land use. By co-digesting food waste with used water sludge, Singapore is working towards an energy self-sufficient used water treatment facility, while also minimising solid waste for disposal at landfills. The novel technologies adopted at Tuas Nexus were researched and developed at demonstration plants before being implemented on a full scale.
Under SDG 6, PUB is leading research and development for the water sector in Singapore and has integrated various technologies at a system level to achieve the outcome of ensuring adequate access to water and sanitation. Water resource management has also been integrated with waste management in the example of the Tuas Nexus, where synergies have been identified to reduce waste products and increase energy production from biogas to reduce the facility’s overall carbon footprint. This in turn will help to achieve a more sustainable management and efficient use of natural resources, thus achieving the goals of SDG 12. On SDG 13, PUB is part of Singapore’s GreenGov.SG movement that aims for the public sector to achieve net zero emissions around 2045, which is earlier than the national target of 2050. The improved energy efficiency and decarbonisation of water processes will contribute significantly towards meeting this net zero ambition to combat climate change.
