  2. 2. Polybrominated diphenyl ethers and Tetrabromobisphenol A : Chemical synthesis, X-ray crystallography and Photochemical degradation

    University dissertation from Stockholm : Institutionen för miljökemi

    Author : Johan Eriksson; Åke Bergman; Lars Eriksson; Mats Tysklind; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Chemistry Environmental chemistry; NATURVETENSKAP Kemi Miljökemi;

    Abstract : In the 1960s’ several manmade chemicals were detected in the environment, far from their sources. The most well known, and most likely those with the largest impact on the society, were DDT and its related compounds, and PCBs. These anthropogenic compounds were characterised as persistent organic pollutants (POPs). READ MORE

  3. 3. Pyrolysis and Detoxification of Waste Electrical and Electronic Equipment (WEEE) for Feedstock Recycling

    Abstract : The trends in waste electrical and electronic equipment (WEEE) generation shows that their volume constantly increases, while the current waste management technologies have proven to be insufficient in order to meet the strict criteria and the new legislations of the European Union. Pyrolysis and thermal treatment in general could be a valuable solution for closing the loop of materials and could contribute to the energy demands of modern society. READ MORE
