  4. 2. Effects of Simulated Recycling on Polyolefin Materials

    Author : Anna Jansson; RISE; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; recycling; oxidation; degradation; polyolefins;

    Abstract : Production and handling of waste is a matter of concern in most countries, and one way to reduce the amount of waste is recycling. Since synthetic polymers are made from non- renewable resources and are used in large amounts, often for short periods of time, they should be recycled in a sustainable society. READ MORE

  5. 3. Long-term Properties of Sustainable Polymeric Materials : Mechanical Recycling and Use of Renewable Resources

    Author : Emma Strömberg; Sigbritt Karlsson; Amparo Ribes-Greus; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sustainable materials; mechanical recycling; polyolefin; reprocessing; accelerated ageing; chromatography; biofilm; microenvironment chamber; environmental degradation; biocomposite; nanocomposite; Polymer chemistry; Polymerkemi;

    Abstract : New strategies for management of the accumulating amounts of plastic waste are required, to achieve a sustainable development in terms of material production and use. After service life, the materials should be recovered and recycled efficiently to provide a valuable resource for future applications. READ MORE

  6. 4. Heterogeneous Degradation and Recyclability of PP Studied by Imaging Chemiluminescence

    Author : Mikael Hamskog; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Teknik; Technological sciences; recyclability; mapping; surface; heterogeneity; heterogeneous; evaporation; ageing; hamamatsu; russel; ICL; CL; Irganox 1010; Irganox 1076; oxidation; hydroperoxide; radical; carbonyl; luminescence; chemiluminescence; imaging chemiluminescence; recycling; stabilization; polypropylene; degradation;

    Abstract : Oxidative degradation is a serious threat to long-term use and recyclability of polymers. Successful recycling of polymeric quality products requires characterization of the polymer material after reprocessing and use. READ MORE

  7. 5. Comparison of incineration and pyrolysis of NMC-lithium-ion batteries – determination of the effects on the chemical composition, and potential formation of hazardous by-products

    Author : Gabriele Lombardo; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; vacuum; recycling; carbothermal; Keywords: Lithium-ion batteries; incineration; pyrolysis.;

    Abstract : Several industrial lithium battery recycling processes use thermal pre-treatment in an oxidative or inert atmosphere, or in a vacuum, to separate the battery components and remove organic material. However, a comparison of these pre-treatments on the microstructure and composition of waste material and production scrap LiBs has not been explored as well as there is a scarcity of information about the character of by-products generated during the processing.
