Tuas Counting and Sorting Facility Opens to Automate Islandwide Bottle and Can Returns

The automated plant centralizes deliveries from reverse vending machines and uses robotics, enclosed air transport and sensor-driven separation to raise recycling quality for sale to recyclers.

Overview

  • The facility is now operational and receives daily deliveries from about 1,300 reverse vending machines, processing roughly 1,200 bags of flattened bottles and cans each day.
  • Robotic arms and AI overhead cameras pick up colour-coded bags, slit them open and empty contents into a screw bunker where residual liquid is drained to reduce contamination.
  • An enclosed air-conveying system moves containers through a sorting line that uses magnets to pull out steel, an eddy-current separator for aluminium, and infrared optical sensors with air jets to separate four plastic types.
  • Sorted materials are compressed into bales on site and sold to a panel of recyclers, with revenues and producer fees helping fund the Beverage Container Return Scheme.
  • The plant’s design—automation, label removal, enclosed pipes and liquid drainage—aims to cut odour and contamination, improve material purity compared with blue-bin recycling, and scale recovery of deposit-marked containers nationwide.
