The texts have been copied from the respective Finnish site, and they will be translated into English.


Finnish energy company Vapo is planning a municipality solid waste incinerator (MSWI) in Hämeenkyrö. The purpose is to produce electricity, heat and steam for the community and the nearby cardboard mill. The waste would come from Pirkanmaa area. The planned thermal power would be 80 MW, and it would use 200 000 tons of solid waste and sludge per year. [1]

The plant would locate near the municipality centre, and also near a source of groundwater. The ash produced would be transported to a hazardous waste landfill in an other municipality (either Forssa or Riihimäki) There is an active citizen group against the plan. [2]

Currently there is a gas combi plant near the cardboard mill, and it provides a major part of the energy to the mill. [3] [4] Thus, in addition to the incinerator, there are issues related to the existing gas plants, and land owning. [5] [6]
