How Does AWCS Work?

The Automated Waste Collection Systems (“AWCS”) is a vacuum/pneumatic waste conveying system that
transports solid waste at high speeds in reticulated steel pipes to a sealed container bin, which is then
transported to a landfill or Waste Collection centre

​

The illustration below shows the basic concept of how a standard STREAM Automated Waste Collection System (AWCS) works:

​

1. Chutes and hopper doors are used to feed waste into the system

2. Storage sections hold waste between transport cycles

3. Primary air inlet that creates an active high speed air path in the pipe network

4. Discharge valves that periodically open to allow movement of the waste into the active air path

5. Transport pipes that form the waste path between the storage sections and the Central Waste Handling Facility (CWHF) / bin room.

6. Outdoor load stations that may also feed smaller quantities of waste material into the system
