A reason for choosing Envac’s optical sorting system was that it is a proven technology, can easily be introduced to the entire municipality, and it adds no extra cost for the households. The automated system implies a lower workload for the staff.
The sorting plant in Linköping handles two fractions, residual waste and food waste. It is built adjacent to the district heating plant where the residual fraction is incinerated and converted to heat and energy.
The food waste is transported to a nearby pre-treatment plant, where it is processed to biogas and biofertiliser.
