What we do

Every year around the world millions of tonnes of  coffee waste are sent to the incinerator or landfill. Coffee grounds, however, are an excellent source of nutrients and perfect for growing mushrooms. The coffee making process sterilizes the grounds and if used fresh they don’t require additional treatment.

Helsieni grows oyster mushrooms on Helsinki’s coffee waste and aims to be part of the city’s sustainable food ecosystem.

Our Farm
