Residents can enjoy clean surroundings because the waste is conveyed underground

Kivistö area’s residents take their waste to the nearest waste collecting points, which are situated in many locations in the area. The solution helps residents to sort waste as there are typically 4 inlets at each waste collecting point: bio waste, mixed waste, cardboard and paper. Waste is conveyed through underground pipelines to a waste transfer terminal. From there it is taken to be recycled, turned into heat for homes, or used for other purposes.

The underground waste collections system benefits the customer the following ways:

• Building is more effective because there is no need to build extra waste collection rooms.
• Minimizes the cost of equipment, handling and collection of waste in the area.
• Makes the surroundings more pleasant without the unpleasant odours or other disadvantages of overfilled waste bins or waste truck traffic.
• All the waste is collected at the waste transfer terminal from where it is transported for further processing or for reuse.

The waste is conveyed through the pipes to the waste transfer terminal.
