The brief

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 into the operation of the sorting plant the target of 50% sorted waste was accomplished.

The solution

The choice fell on optical sorting to make sorting of both food waste and packages user-friendly for the households. It is a flexible system that minimizes environmental impact and energy consumption.

The plant sorts seven fraction and is owned by ESEM (Eskilstuna Strängnäs Energi och Miljö AB). Today several municipalicties are connected to the system which makes it the best of its kind in Sweden when it comes to recycling.

Capacity 18.000 tons/year

Resources Food, textile, plastics, paper, newspaper, metal and residual waste

Users 175.000


In 2016 the plant was extended in order to treat a larger tonnage of household waste from adjacent municipalities.

In 2017 Eskilstuna and Strängnäs introduced a seventh color (fraction) and became the first Swedish municipality to sort fabric from household waste. Changes were only made to the camera system which controls sorting and no further reconstruction of the plant was needed.

The colour sorting made it easy to achieve our environmental targets
