1. Expansion of Sickla treatment plant : A study about the replacement of standard concrete to green concrete
Master-uppsats, KTH/BetongbyggnadSammanfattning : Stockholm Vatten has decided to close down the Bromma waste water treatment plantand manage the waste water from Bromma together with the waste water from the formerEolshällsverket to Henriksdal’s waste water treatment plant. Henriksdals wastewater treatment plant will be expanded for higher purification requirements and loads,estimated to be finished until 2040. LÄS MER
2. Destruktion av per- och polyfluorerade alkylsubstanser (PFAS) vid förbränning i avfallsförbränningsanläggningar
Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : Per- and polyfluorinated alkyl substances (PFAS) are a group of environmentally harmful chemicals. The group consists of more than 4730 different substances including two of the most famous ones; PFOA and PFOS. PFAS consist of carbon backbones connected to fluorine. LÄS MER
3. Material identification using X-ray diffraction
Kandidat-uppsats, Mittuniversitetet/Institutionen för elektronikkonstruktionSammanfattning : This study reviews the theoretical and experimental aspects of the X-ray diffraction (XRD) technique and evaluates its use in identifying toxic elements or compounds in waste that has been incinerated. Many industries incinerate materials that contain large significant amounts of toxic elements, and these elements should be identified and re-moved to reduce environmental pollution. LÄS MER

Master-uppsats, KTH/MaterialvetenskapSammanfattning : Paper and pulp industry and steel industry are two major industries in Sweden, both of which are facing big challenges to treat their waste products properly. In this thesis work, initial evaluation of mechanical properties of briquettes made of waste products was performed. LÄS MER
5. Energy recovery – Gasification, combustion or plasma? : Competitor or complement?
Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronikSammanfattning : Abstract Energy recovery – Gasification, combustion or plasma? - Competitor or complement? The Swedish waste-to-energy system has been developed during many years, and the facilities are well established within the waste management system. Even though the waste volume is significantly reduced by 70 – 80 %, the residues are quite challenging to manage due to high content of pollutants. LÄS MER
