Automated Vacuum Collection
|This article needs additional citations for verification. (July 2007)|
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.
The system originated in Sweden, with the first one installed in 1961 at Sollefteå Hospital. The first vacuum system for household waste, was installed in the new residential district of Ör-Hallonbergen, Sweden in 1965.
The inventor of the system, Envac AB (Sweden, formerly known as Centralsug AB), is still the leader in the market. Article about the first automated vacuum collection system ever. History about the invention of automated vacuum collection system.
The system is used in more than 30 countries.
There are close to a thousand systems in operation all over the world - in China, South East Asia, Korea, the Middle East, the U.S, South and North Europe. In the U.S.A. this type of system is installed in several places but Disney World and Roosevelt Island are the most well-known.
Major cities in which the system is operating include Copenhagen, Barcelona, London, and Stockholm.
A system is planned to be installed in the new Jätkäsaari residential neighbourhood in Helsinki, Finland. All housing cooperatives and other apartment buildings are obliged to join the network. The system envisioned for Jätkäsaari would help facilitate the separation and recycling of waste.
Each building will have a collection point with up to five wastebins or tubes, each for different types of waste and with the capacity to store several parcels of waste. The underground tube network would act in a manner similar to a packet switched telecommunication network, transporting one kind of waste at a time. Once an input bin is filled, or capacity is available, it is transferred to the central collection site combined with the same class of waste.
Similarly in Finland, a new suburban development, being built in the city of Tampere, will be home to 13,000 inhabitants, creating appriximately 5,000 jobs along the way. The suburb of Vuores will have a total of 124 collection points and 368 waste inlets. The system's daily collection capacity for dry waste, bio waste, paper and recyclable cardboard comes to a combined total of 13,000 kilos.
The MetroTaifun Automatic Waste Collection System  was selected for Vuores since it consumes only 1/3 of the energy compared to conventional pneumatic waste collection solutions, and 1/2 of the traditional garbage truck and container based collection method. When ready, the system will consist of about 400 waste inlets and 13 km of pipe work. The MetroTaifun automatic waste collection system has initially start to collect waste in the 2012.
Roosevelt Island in New York City uses an AVAC system. Currently it is the only AVAC system serving a residential complex in the United States. A system is planned for a new City Center development in Carmel, Indiana. It would service condominiums, businesses, and a hotel. The city of Montreal has also announced plans for an automated vacuum collection system for its Quartier des Spectacles entertainment district, now under construction. The Magic Kingdom at Walt Disney World Resort also uses an AVAC system to remove garbage throughout the park to a centralized collection hub.
Today, AWCS are quickly increasing size. To take an example of this, the world’s largest AWCS is now being built in the vicinity of Islam’s holiest mosque (Mecca), Saudi Arabia. During the Ramadan and Hajj 600,000 kilos, or 4,500 cubic meters, of waste is generated each day, which puts a heavy demand on those responsible for collecting the waste and litter. In the MetroTaifun Automatic Waste Collection System, the waste is automatically collected from 74 waste feeding points spread out across the area and then transferred via a 20-kilometre pipe network to a central collection point, keeping all the waste collecting activities out of sight and below ground with the central collection point well away from the public areas.
