Our solution

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.

Vacuum suction system prevents the odor

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.
The Results

These inlets provide continuous, 24-hour, fully automatic operation, and serving approximately 15,800 households without even being noticed.
