Management of municipal solid waste is an efficient method to both increase resource efficiency (material and energy recovery instead of landfill disposal) and to replace fossil fuels with renewable energy sources (waste is renewable in itself to a large extent as it contains paper; wood; food waste etc.). The paper presents the general outline and results from a comprehensive system study of future waste management. In the study a multifunctional waste management system integrated with local energy systems for district heating and electricity; wastewater treatment; agriculture and vehicle fuel production is investigated with respect to environmental impact and financial economy. Different waste technologies as well as management strategies have been tested. The treatment is facilitated through advanced sorting; efficient treatment facilities and upgrading of output products. Tools used are the ORWARE model for the waste management system and the MARTES model for the district heating system. The results for potential global warming are used as an indicator for renewable energy. In all future scenarios and for all management strategies net savings of CO2 is accomplished. Compared to a future reference the financial costs will be higher or lower depending on management strategy.
