16. Unsaturated Phase Environmental Processes in MSWI Bottom Ash
Sammanfattning : 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. LÄS MER
17. Hydrometallurgical Treatment of Neodymium Magnet Waste
Sammanfattning : Recent decades have seen a considerable increase in the usage of rare-earth elements (REEs) in modern technologies and green energy sources. Recycling of REEs out of end-of-life products and E-scrap has become an alternative to mining them out of primary ores due to their supply risk in some countries and the development towards circular economies.

18. Removal of Metal Ions from Wood Chips during Acidic Leaching
Sammanfattning : Wood chips are the main source of intake of non-process elements at kraft pulp mills. It would be advantageous to decrease the content of these elements in the chips prior to pulping. LÄS MER
19. Process Intensification through Acoustic and Hydrodynamic Cavitation
Sammanfattning : Process industries are cornerstones in today’s industrialized world. They contribute significantly to the development of diverse commodities and materials that are used in our daily lives. Process intensification is an approach implemented to boost manufacturing efficiency and capacities in a more sustainable and energy efficient way. LÄS MER
20. Ecotoxicological classification of ash materials
Sammanfattning : Incineration of waste is increasing in the EU. However, in the incineration process, both fly and bottom ash materials are generated as waste that requires further action. A common goal throughout Europe is to find ways to utilize ash materials in an environmentally and economically efficient manner in accordance with the current legislation. LÄS MER
