| Summary: | Pursuing the possibilities of increasing efficiency, saving costs and improving environmental performance more and more companies today are looking into the possibilities of industrial synergies between companies andprocesses. This study is considering the possibilities of industrial symbiosis between combined heat and power plant (Fortum) and a waste sorting facility (Ragn Sells). The paper shows possible scenarios of utilization heat fromCHP for the various processes within the waste treatment facility. The work includes the overview of previous research done in this area as well as theoretical analysisand estimation of the probable economic and environmental effects from the application of industrial symbiosis. The study covers several possibilities for the industrial symbiosis between CHP and waste treatment facility in form of heat application for the waste streams upgrading.The study proposes the heat application for the following processes: composting speed-up, anaerobic digestion, sludge drying, waste oil treatment and concrete upgrading. In the result of the work the conclusions are made concerning the possibility and feasibility of application of the proposed scenarios and their environmentaland economic effects. === Division Industrial Ecologywww.kth.se/itm/indecowww.ima.kth.se
