Sustainable Waste Solutions for a Multi-Use Riverfront Development


Union Square is a planned mixed-use development project, connecting Clarke Quay riverfront with the CBD fringe, with a completion date targeted for 2028.
The project emphasises sustainability and ESG goals in its design, where a sophisticated waste management system was planned to efficiently handle the diverse waste streams from Union Square’s residential, commercial, and hospitality activities.
Implementation Approach
Green Wave Solutions (GWS) implemented an integrated waste management solution tailored to Union Square’s mixed-use layout. In the residential tower, a two-fraction AIRWASTE pneumatic collection system was installed, featuring dual chutes for separate disposal of general waste and recyclables.
For the office and retail components, a high-performance mobile waste compactor with an integrated bin lifter was provided. Additionally, a proprietary Waste Measurement Solution was deployed, allowing building management to track waste generation continuously and accurately.


The data is logged and can be accessed through a digital dashboard, supporting the project’s ESG objectives by providing transparency in waste handling. Notably, the automated monitoring capability also opens the possibility for user-level waste tracking and pay-as-you-throw billing in the future.
The system integrates a dual-fraction AIRWASTE chute for residential strata and mobile compactors with bin lifters for commercial areas. Real-time sensors monitor waste and recyclables, transmitting data to a central dashboard for reporting and optimisation.
By combining pneumatic conveyance with automated measurement, the solution aligns with ESG objectives, reduces haulage frequency, and enhances operational efficiency across the mixed-use development.
“Union Square demonstrates how modern waste systems can support both operational efficiency and ESG accountability, turning a basic utility into a transparent, data-driven service for sustainable urban living.”
