Installation of the system.

The pneumatic refuse conveying system (in short, PWCS[1]) is a type of waste disposal system that uses air to move refuse through pipes to collection points.

Refuse is conveyed through steel pipes by a 20–25 meter per second air current to accomplish the goal.

Notable examples in Europe were implemented in the Stockholm area in Sweden.[citation needed] and Leganés and Barakaldo in Spain. Another well known, yet rarely seen example is the one used in the utilidors in the Magic Kingdom theme park in Orlando, Florida.[2]

A pneumatic refuse collection system on Roosevelt Island, New York City, is said to be the largest in the United States and the only system in the U.S. serving a residential complex in this case nearly 10,000 people.[3][4]
