Anaergia Inc. has signed a contract to supply its organic waste treatment solutions to the joint venture selected by Singapore's National Environment Agency (NEA) for its Tuas Nexus integrated waste management facility (IWMF) engineering, procurement, and construction package 2(EPC2) contract. The EPC2 contract will include a 400-tonne-per-day food waste treatment facility (FWTF), which Anaergia will design and build using its waste treatment technologies. The construction of this waste treatment facility will be a key step toward realizing Singapore's vision of becoming a zero-waste economy.
NEA awarded the EPC2 contract to a joint venture between UES Holdings Pte Ltd (UESH) and China Harbour (Singapore) Engineering Company Pte Ltd (CHEC). The joint venture's submitted proposal was evaluated based on process design and optimization, resource efficiency, Singapore's Green Mark initiatives, plant layout, and value for the cost.
Using Anaergia's technologies, the FWTF will be Singapore's primary facility for the treatment of source-segregated food waste. The facility will use Anaergia's technologies, which first separates inorganic materials from food waste. The food waste fraction will be processed into a slurry, which will be anaerobically co-digested with used water sludge at the Tuas Water Reclamation Plant (Tuas WRP) to produce biogas. The co-digestion of food waste slurry and used water sludge will increase biogas production at Tuas WRP and improve energy recovery from waste while optimizing land use.
Tuas Nexus will be Singapore's first integrated water and solid waste treatment facility. It will provide an innovative and sustainable solution to meet Singapore's long-term solid waste management and used water treatment needs.
