Sustainable & Circular Process Technology Group

SCPTG Sustainable & Circular Process Technology Group Turning Today’s Wastes Into Tomorrow’s Resources 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.

Customer Stories Novel Membrane Technology Project with GlaxoSmithKline (GSK) The reduction of waste from chemical processes is becoming a strong focus in many industries as they move towards a green and sustainable circular economy. For chemical companies, one of the major waste streams is water-solvent and solvent-solvent mixed waste. New membrane methods of micro-, nano-level separation are emerging areas that contribute towards an effective liquid waste treatment. Together with GSK, we developed a novel membrane technology, which has several significant advantages over conventional polymeric membranes in terms of filtration selectivity, material robustness, and reliability. The membrane is suitable for non-aqueous and gaseous molecular filtration, with a myriad of potential applications in chemical processes for industrial sectors such as pharmaceutical, biomedical, food & beverage, and more. One exemplary application of this technology is to separate solvent from solvent-solvent mix and solvent-waste solutions to improve resource circularity and manufacturing sustainability, while reducing carbon footprint and waste generated. Multi-Physics Hybrid Process for Wastewater Treatment In wastewater treatment industry, typical chemical treatments include coagulation/flocculation, pH adjustment, membrane fouling control, and others. These resulted in high treatment cost and secondary pollution. SCPT developed an integrated wastewater treatment system to address these issues using a hybrid multi-physics approach, which combines configurable technology components including SIMTech’s electrochemical advance oxidation process (EAOP), nano-bubble generation and our unique filtration technology. The system offers competitive advances such as chemical-free treatment, energy efficiency and self-regeneration of membrane over conventional treatment processes. Two pilot systems were showcased at the 2021 National Science Challenge in the Semi Final round. This technology enables a sustainable close- loop water treatment. MORE STORIES?
