STOCKHOLM — Swedish company Envac has designed an underground pipeline system that can collect trash by vacuum. <br /> <br />According to the company, the waste inlets can be located outdoors or indoors. When the waste is being thrown into the inlet, it will then slide down a pipe and enter a waste tank underground. The waste tank is emptied by a vacuum truck when it reaches its capacity. <br /> <br />The truck empties the tank via a docking point, which is often located outside residential areas. It has a vacuum system on board, which sucks the waste out of the tanks and into the truck, where it is compressed. <br /> <br />The waste collection system can be upgraded to include a pay-as-you-throw function that charges users on what they throw into the inlets. <br /> <br />The vacuum waste collection system was developed in the late 1980s. It has since been installed in countries such as Sweden, Denmark and Norway. <br /> <br />According to Waste360, Coney Island and a new development in Chelsea district in New York are considering installing the vacuum system.
