Abstract [en]

According to the statistics at the EC Commission, Sweden is the Champion byfar in Europe in terms of renewable energy. It comprised around 45% of the totalin the year 2008. This position has been reached by a combination of naturalresources, political determination and technology development.A major contributor to this is the extensive utilization of district heatingwhich amounts to around 50 TWh per year, and which covers about half of thetotal need for industrial and domestic buildings. The district heating is basedmainly on combustion of bio fuels together with waste and some peat.This practice is generally very positive from a sustainability perspective forthe following reasons: (1) bio fuels are renewable, and so is peat, although over alonger time span; (2) waste is being recovered for energy purposes; and (3) ashmaterial is, in many cases, re-circulated and recycled.However, sustainability is not only about total percentages, but also on thequality in the processes, especially in terms of qualification of fuels and ashesand the associated possibilities for more efficient combustion and incinerationprocesses as well as ash utilization. Efficiency in this regard of course alsoincludes protection of health and the environment. These aspects are explored ina technical as well as a legal perspective, and some possibilities for furtherdevelopment and improvement are identified and discussed.The compilation and analyses are based on more than ten years of researchreports (mostly in Swedish) financed by District Heating in Sweden (SvenskFjärrvärme), [The Swedish] Thermal Engineering Research Institute(Värmeforsk), the Swedish Waste Management (Avfall Sverige) and SvenskaEnergiaskor AB (which translates to: “Swedish Energy Ashes Inc.”).
