The Stormossen company is owned by six municipalities in Ostrobothnia to manage the waste from the owner municipalities. The company’s turnover was 13.4 million euros in 2021. The centre of the business consists of the waste treatment plant in Koivulahti (Kvevlax) in the municipality of Mustasaari (Korsholm). Stormossen currently employs about 42 people.

Stormossen’s business is an example of a real circular economy. We deal with biowaste and sludge and convert it into compost soil and biogas vehicle fuel. The result is a climate-smart cycle of nutrients and energy.

Sales of compost soil have been ongoing since 2009 and have included garden soil and lawn soil. The company began to handle the sale of compost soil under its own initiative in 2016. The compost soil is made from digestate produced from the digestion of biowaste and sludge.

The recycling rate for municipal waste is over 99%. Our goal is that 65% of the municipal waste produced is recycled as material at the latest in 2030. Stormossen maintains a comprehensive and easily accessible infrastructure to receive waste. The network consists of ecopoints, key containers for combustible waste, campaign collections, manned and unmanned recycling stations, mobile recycling stations as well as the recycling mall Minimossen. The services also include a pick-up service and an active information policy promoting the services we provide.
