Tuas Nexus

Summary

Trust Nexus is an innovative, integrated facility in Singapore that combines water reclamation and waste treatment to create a circular economy. By co-locating the Integrated Waste Management Facility (IWMF) and the world's largest Membrane Bioreactor (MBR) facility, it maximizes synergies, turning waste into resources. The project aims to reduce landfill waste by 30% by 2030 and boost sustainability efforts, generating biogas and electricity while saving costs and optimizing land use. Trust Nexus is a groundbreaking solution to Singapore's growing environmental challenges, offering a model for global water and waste sustainability.
