With the increasing demands of the Swedish national goals the municipality of Halmstad chose optical sorting of household waste.

The choice fell upon optical sorting, because it could be introduced with a minimum of efforts for the company and the households.

The main reason for chosing optical sorting was how easy the system could be introduced. Different colored bags that do not leak are thrown in the same trash cans as before. With optical sorting there is no need for replacing the bins nor replacing the garbage trucks.

The plant is owned and operated by HEM (Halmstad Energi och Miljö AB). It’s build for two fractions, food and rest fractions, with the option to easily extend it to six fractions. The brand new building also contains a pre-treatment facility for the sorted food waste, which becomes biofuel.


The plant has a capacity to grow in case Swedish municipalities also will be responsible for collecting packages. Hopefully it will sort more fractions and receive waste from other cities in the future.
