David Payne of the Regional Municipality of Niagara tries out the Envac system in Stockholm.

The Envac automated waste collection system was one of the niftiest bits of technology I saw on a trip to Sweden in 2004. Waste is first deposited in the outdoor or indoor outlets then sucked through an underground pipe at 70 kph to a central processing facility. The pipes were integrated with existing city sewage pipes.

Several hundred thousand Stockholmers are connected to similar systems.Envac system
