Challenge

When 5.5 million people share a dense area, water and waste management presents a unique challenge. Singapore’s National Water Agency (PUB) and Singapore’s National Environment Agency (NEA) have appointed an international team of consultants to establish an Integrated Waste Management Facility (IWMF) alongside the world’s largest water reclamation plant (Tuas WRP) designed to treat the nation’s solid waste and used water, respectively

Solution

Ramboll is responsible for the IWMF facility, while a joint venture consisting of Black & Veatch and AECOM (B&V+AECOM JV) is responsible for the Tuas WRP. The facilities efficiently collect, treat and discharge used water, enhance water sustainability by enabling large scale water recycling and reap the potential synergies of the water-energy-waste nexus.

Result

IWMF will be the world’s largest energy recovery facility. By co-locating the facility next to Tuas WRP, it will be possible to achieve the highest energy efficiency and lowest greenhouse gas footprint. With 2×4 combustion lines, the IWMF will be able to treat more than 2.5 million tons of solid waste annually, which is five times the capacity of the largest European waste-to-energy facilities. The sludge incineration plant will also be among the largest in world with two large fluidized bed combustion systems.
