Editor's Notes
- #4 Well, it is not dissimilar to a giant vacuum cleaner. In order to collect and remove the waste we install a network of pipes, connecting all buildings in the area (point at the pipe system). Close to the buildings, or inside the buildings we install so called waste inlets for the residents to drop off their waste (point at the inlets). One waste inlet per waste stream. The waste is stored in the inlet underground until collection (point at the valve). At the end f the pipe system we install, what we call a collection terminal. This is where the waste is air-transported to. At certain fixed intervalls during the day, or at need, the collection process is initiated. The process starts with the fans in the terminal being activated. This creates an underpreasure in the pipe system. Then an air inlet valve close to the inlet first to be emptied is opened, letting air into the pipe. When the air has reached a set velocity, the waste is released in the inlet and air-transported all the way to the terminal where it is stored in a container. A simple process, taking only seconds to complete. www.envac.net
- #5 We have a world wide operation. For us it is important to have competent staff, close to our customers and close to our markets. Our local offices are therefore trained to handle all types waste handling related issues, drawing on the competence and experience from our world wide organisation.
- #7 The mobile Vacuum system from Envac is an alternative to the stationary waste handling system. Here the waste is collected by a special truck, vacuuming the waste from undergrounds tanks connected to a common docking point. The mobile system is particularly attractive for lower density housing. The collection process is very similar to that of Envac’s stationary system. The waste is transported by air at great velocity under ground. Both outdoor and indoor inlets can be used.

- #11 The litter bin system can be connected to both Envacs stationary system and the mobile system. It could also be installed stand-alone. The working principles are the same as for the other systems. www.envac.net
- #12 This is one of Envac’s latest products. Overfilled litter bins is often an unattrictive and disturbing element to visitors, businesses and residents. With the Envac litter bin system this becomes a memory of the past. The litter bins can be emptied on demand as often as needed, without the need to send a vehicle in on a crowded street. www.envac.net
- #13 Optibag is a well tried system for the handling of source separated household waste. It is both simple and cost efficient to install and use. When introducing more fractions or increasing the quality of the sorting in other ways, it is easy to add new colours to the system. Optibag AB is a 100% wholly owned subsidiary of Envac AB. www.envac.net
- #14 The Optibag system is a different waste handling technology where waste is separated by using differently coloured bags for different waste streams/fractions. These bags are all thrown into the same bin or Envac inlet. At an Optibag plant the co-mingled bags are separated and put into separate containers at great speed. The process works by optical identification of the bags. The technology is ideal for waste separation where space for separate waste bbins or chute is a problem.
