  1. 21. Carbon materials: towards a circular economy through thermochemical recycling of mixed waste

    Författare :Isabel Cañete Vela; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; circular economy; recycling; mixed waste; thermochemical; carbon materials;

    Sammanfattning : Carbon materials, such as paper, wood, plastic and textiles, play an important role in our everyday life, from clothes and packaging to infrastructure. However, the use of those materials follows a linear way. We take carbon resources, we make products, and we discharge them in a short amount of time, producing GHG emissions along its supply chain.

  3. 22. Environmental and Economic Assessment of Swedish Municipal Solid Waste Management in a Systems Perspective

    Författare :Ola Eriksson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; waste management; LCA; LCC; systems analysis; decisionmaking; computer model;

    Sammanfattning : Waste management is something that affects most people. Thewaste amounts are still increasing, but the waste treatment ischanging towards recycling and integrated solutions. In Swedenproducers’responsibility for different products, a taxand bans on deposition of waste at landfills implicates areorganisation of the municipal solid waste management. LÄS MER

  4. 23. The economics of household packaging waste : norms, effectiveness and policy design

    Författare :Olle Hage; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi;

    Sammanfattning : This thesis consists of an introduction and four self-contained papers, which all deal with the economic effectiveness of the Swedish producer responsibility for packaging materials. Paper I analyzes the determinants of household packaging recycling efforts in Sweden by employing data on households' self-reported behavior. LÄS MER

  5. 24. Quality Assessment for the Improved Use of Recycled Styrenic Polymers : Application to packaging and electronic waste

    Författare :Francisco Vilaplana; Sigbritt Karlsson; Alfonso Jimenez; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymer chemistry; Polymerkemi;

    Sammanfattning :  Polymeric waste materials should be considered resources for the manufacture of new products through recycling processes, with a similar status as virgin fossil-based plastics and biopolymers from renewable resources. Several efforts can be done to achieve this qualitative quantum leap and introduce recycled products in the market with competitive performance. LÄS MER

  7. 25. Risk of spontaneous fires at temporary storages sites for organic material, waste fuels and recyclables: Quantification and mitigation

    Författare :Muhammad Asim Ibrahim; William Hogland; Ghasem Najafpour; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; temporary storage; risk of fires; spontaneous ignition; biofuels; recyclables; waste fuels; Miljövetenskap; Environmental Science;

    Sammanfattning : Economic and environmental constraints have created increasing demand for (material and energy recovery) and recycling of waste generated from households, commercial and industrial activities. A wide variety of materials waiting for sorting, recovery, recycling and disposal are stored at temporary storage sites (TSS) where physical, biotic and abiotic processes can lead the stored material to spontaneous ignition.
