Keppel Integrated Engineering (KIE), the environmental technology and engineering arm of Keppel Corporation, officially opened Singapore’s newest Waste-to-Energy (WTE) plant, the first to be built under the National Environment Agency (NEA)’s Public-Private Partnership (PPP) initiative.

The Keppel Seghers Tuas WTE Plant has the capacity to treat 800 tonnes of solid waste a day to generate more than 20MW of green energy, contributing to Singapore’s electricity supply. It is the first incineration plant in Singapore to showcase WTE technology from a local company, and also one of the most compact WTE plants in the world.

KIE, through its wholly owned subsidiary, Keppel Seghers Engineering Singapore, designed and built the WTE plant incorporating Keppel Seghers’ combustion grate and flue gas cleaning proprietary technologies, and will operate and maintain the plant for 25 years under a contract awarded by the NEA.

Together with the Senoko WTE Plant, which Keppel Seghers also operates, Keppel will treat close to half of Singapore’s incinerable waste.

Both the WTE plants and the Keppel Seghers Ulu Pandan NEWater Plant form the initial portfolio of K-Green Trust which was listed on the Main Board of the Singapore Exchange yesterday.

Meanwhile, Keppel also announced that research on Memstill by the Keppel Environmental Technology Centre (KETC) is entering the next milestone in technology implementation with the design, construction, and operation of a demonstration plant.

The plant, to be built on Singapore Refining Company’s petroleum refinery located on Jurong Island, will have a freshwater production capacity of 100m3/day.

Memstill is a new technology that produces desalinated water using waste heat and membrane-based distillation.
