21. Unsaturated Phase Environmental Processes in MSWI Bottom Ash
Abstract : Every year, Sweden produces 1.5 million tons of incineration residues from waste to energy plants. Among these residues bottom ash(BA) due to its large volume and good geotechnical quality can be reused as an alternative construction material. READ MORE

22. Characterisation of organic materials from incineration residues
Abstract : The organic material present in incineration residues has been examined. Water leachable organic material was characterised and classified into hydrophilic and hydrophobic acids, neutrals and bases. Changes of the organic material during weathering were followed. READ MORE

23. Multiscale methods for the fundamental understanding of diesel soot mitigation
Abstract : Current regulations for diesel exhaust emissions cannot be met by engine improvements alone, and for this reason the diesel particulate filter (DPF) is a widely used aftertreatment component for the control of diesel particulate matter (PM). The DPF functions by trapping PM and destroying it by oxidation. READ MORE

24. Impact of Ash on the Properties of Fluidized Bed Materials
Abstract : The utilization of the fluidized bed technology offers the possibility of thermally converting a large variety of biogenic feedstocks. The characteristics of the bed material which is used in the process play a major role regarding the overall process performance. READ MORE

25. Distribution and chemical association of trace elements in incinerator residues and mining waste from a leaching perspective
Abstract : Incineration is a mainstream strategy for solid waste management in Sweden and all over the world. Improved knowledge and understanding about the distribution of trace elements (in ashes) during incineration, and how trace element partitioning respond to the changes in waste composition, are important in terms of combustion process optimization and plant efficiency.
