1. Ash Products for Nutrient Recycling in Forestry : Leaching and Drying Characteristics
Sammanfattning : As the demand for carbon dioxide neutral energy sources increases, forestry becomes more intensive. Entire trees are removed from the felling sites threatening the nutrient balance of the forest soils. LÄS MER
2. Chemical Properties of FBC Ashes
Sammanfattning : In this thesis several aspects of ash chemistry are discussed. An issue of primary concern for boiler operators is the formation of ash deposits. New biomass fuels are introduced, many of which have unfavourable ash melting behaviour due to high levels of alkali metal species and chlorine. LÄS MER
3. Leaching, filtration and displacement washing in a treatment process for MSW combustion fly ash - laboratory scale and plant studies
Sammanfattning : Municipal Solid Waste combustion, as one of the waste management tools, starts to play an important role nowadays in heat and energy generation. However, MSW combustion leads to generation of other wastes - combustion residues, including ashes, which require a proper management. LÄS MER
4. 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
