Westenergy Oy Ab owns and operates a modern Waste-to-Energy plant which utilises source-separated combustible waste as fuel. The WtE plant is located in Mustasaari, near the city of Vaasa in Finland and has been in operation since 2012.

The Westenergy Waste-to-Energy plant is an important part of a well-functioning waste management system as in the plant, energy is extracted from non-recyclable waste in an efficient, safe and clean way.

Westenergy’s co-operation partner Vaasan Sähkö Oy uses the steam produced in the plant to produce electricity and district heating. Over one third of the district heating needed in the Vaasa region is produced in the plant.

Westenergy Oy Ab is owned by five municipal waste management companies (Lakeuden Etappi Oy, Ab Stormossen OyVestia Oy, Botniarosk Oy Ab ja Millespakka Oy). The shareholders operate in an area covering approximately 50 municipalities and over 400 000 inhabitants.
