The future of local waste material utilization in distributed energy production in Finland
A very small part of waste management has been carried out by incineration in Finland.About 300 kt of waste is incinerated or burned with other fuels. Waste materials have beenused in energy production mostly as co-combustion fuels at several energy production plants.The waste incineration directive of the European Union sets tight regulations for the emissionlimits, their measurements, as well as for temperature and residence time conditions in thefurnace. The costs of solid recovered fuel (SRF) utilization will increase remarkablyespecially in small heating plants because of these demands.In this study we focus on the preconditions for the utilization of local waste materials indistributed energy production. We introduce two different cases where a fuel produced fromlocal waste materials is used in small-scale energy production (
