Automated vacuum collection

An automated vacuum waste collection system, also known as pneumatic refuse collection, or automated vacuum collection (AVAC), transports waste at a high speed through underground pneumatic tubes to a collection station where it is compacted and sealed in containers. When the container is full, it is transported away and then emptied. The system helps facilitate the separation and recycling of waste.[1]

The process begins with the deposition of trash into intake hatches, called portholes, which may be specialized for waste, recycling, or compost. Portholes are located in public areas and on private property where the owner has opted in. The waste is then pulled through an underground pipeline by an air pressure difference created by large industrial fans, in response to porthole sensors that indicate when the trash needs to be emptied and help ensure that only one kind of waste material travels through the pipe at a time. The pipelines converge on a central processing facility that uses automated software to direct the waste to the proper container, and then be trucked to its final location, such as a landfill or composting a plant.[1]
