Innovative waste collection system
The Automatic Waste Collection System (AWCS) in Macao is an innovative waste collection solution that saves space and eliminates common environmental impacts, whilst also being safe and user-friendly.
128 outdoor disposal inlets connect with the integrated underground pipe network, which suck the waste to the compaction systems by vacuum. The AWCS’ deodorizing and dust-filtering system and exhaust air channel reduce noise and environmental emissions. Odors and leachates are also controlled inside the inlets during the suction process.
These inlets provide continuous, 24-hour, fully automatic operation, and serving approximately 15,800 households without even being noticed.
