Abstract

The waste management in Europe has been heavily relying on landfills still in the 1990's. Currently new integrated concepts for recycling and energy recovery of waste are demonstrated. In Finland, the new concepts are mainly based on co-firing of waste-derived fuels with solid fuels in combined heat and power production. The Finnish waste management is based on source separation of waste at its origin. In many municipalities the remaining fraction is processed to solid recovered fuels (SRF). The processing of waste in an advanced SRF plant enables to recover still valuable materials for recycling, like glass, metals, aluminium, and paper. Integrated concepts for material and energy recovery are discussed using the Helsinki Metropolitan Area as an example. The greenhouse gas (GHG) emissions and waste treatment costs are the lowest when combustible fraction of waste is recovered and used in energy production in SRF gasifiers connected to existing coal-fired CHP boilers.
