Sustainable and Circular Process Technology (SCPT)



Aligned with the Singapore Green Plan, the Zero Waste Masterplan sets to make Singapore a sustainable, resource efficient and climate resilient nation. One of the aims is to adopt a circular economy approach. To close the loop, and be able to handle new wastes generated from innovations, it is essential to develop enabling process technologies in waste-to-resource management.

SCPTG focuses on innovating process technologies and capabilities to enable a decentralised approach for sustainable production and resource circularity. Other than developing materials, processes and systems for smart segregation and resource repurposing in waste-to-resource management, the group looks to collaborate extensively to co-develop and drive manufacturing processes to be more sustainable and circular.
