Automated Vacuum Collection

The AVAC system here at Sollefteå Hospital was the first ever installed. 

The Automated Vacuum Waste Collection System, also known as pneumatic refuse collection, or Automated Vacuum Collection (AVAC) system, transports waste at high speed through underground tunnels to a collection station where it is compacted and sealed in containers. When the container is full, it is transported away and emptied. The system helps facilitate separation and recycling of waste.
