In 1990, several different waste collection systems were introduced, such as paper and food waste, to be collected separately. This meant an increased number of rubbish bins and transports in Tromsø. As the municipality, situated in the northern part of Norway, has a large geographical collection area with lots of snow in
the winter and roads that are difficult for large vehicles, waste collection became a problem. Tromsø started to look for an alternative where all fractions could be collected in one single bin. The choice fell on Envac’s pneumatic waste collection system combined with optical sorting.
The main reason for choosing optical sorting was all household waste could be collected in one single bin. The municipality could keep its waste collection vehicles and minimise as well as streamline transport.
The plant, sorting five fractions is run by Remiks Husholdning AS. The plants is combined with a pneumatic waste collection system.

Sorting Biostoom Beringen, Belgium
The Limburg Optimo Sorting Facility, launched in 2022, serves 32 municipalities and over 300,000 households. It currently sorts five waste fractions: food waste, garden waste, textile waste, residual waste, and plastic/metal packaging. The facility is built to be flexible, with the option to add two more fractions in the future.
Sorting Eskilstuna, Sweden
Eskilstuna was early with household waste recycling. With the higher demands of The National Goals the municipality introduced optical sorting. Within only a few months the target of 50% sorted waste was accomplished.
Sorting Linköping, Sweden
The target is a region Östergötland without fossil fules in 2030. This was the main political factor for the municipality of Linköping to introduce household collection of food waste using optical sorting.
