Landfill Aftercare

After Care

In order to reduce the environmental impact on the coastal waters surrounding Stige Island, environmental protection measures were required. Therefore a system for collection of leachate was established in 2003. It is integrated with a monitoring system designed to ensure that at least 58 % of the nitrogen contents is recovered - a target set by the local supervising authority, Funen County. Besides the leacthate collection system also gas is being collected from the landfill.

Gas Extraction Services

The former landfill, Stige Island, has the largest dump gas plant in Denmark. The gas formed from the biological processes that take place in dumped refuse is collected via vertical boreholes in the island. The gas provides electricity and district heating in Odense via a combined heat and power plant.

Landfilling

Final Landfilling Services

Final landfilling involves wastes that cannot be recycled or incinerated; these include asbestos waste and shredder waste. Asbestos wastes packed in sealed and labelled dust-proof bags and shredder wastes (residues from shredding vehicles and refrigerators etc.) is landfilled separately at a special deposit.

Gas Extraction Services

Gas is formed as a result of the biological processes that take place during the decomposition of the refuse. This gas is extracted from the landfill cells, and together with the dump gas from the closed Stige Island landfill transferred to a custom-built combined heat and powerplant.
