  1. 1. Material recycling of post-consumer flexible polyethylene packaging waste

    Författare :Ezgi Ceren Boz Noyan; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; degradation; polyethylene; melt-compounding; washing; post-consumer flexible packaging waste; mechanical properties; plastics recycling;

    Sammanfattning : The mechanical and thermal properties of recycled post-consumer flexible polyethylene packaging waste was studied, using material collected and sorted on a large-scale from two sources. Unwashed, laboratory-scale washed, industrial-scale washed, and industrial-scale washed and melt-compounded (industrially recycled) materials were used. LÄS MER

    Sammanfattning : The reuse and closed-loop recycling of food packaging was studied in order to assess consumer safety and the sensory quality (e.g. taste and smell) of packaged food. LÄS MER

  4. 3. Chinese women and consumer culture : discourses on beauty and identity in advertising and women's magazines 1985-1995

    Författare :Perry Johansson; Frank Dikötter; Stockholms universitet; []
    Nyckelord :HUMANITIES and RELIGION; HUMANIORA och RELIGIONSVETENSKAP; sinologi; Sinology;

    Sammanfattning : Chinese women and consumer culture are studied through semiotics and discourse analysis of advertisements and beauty editorials from women's magazines. The trajectory of Chinese consumption and advertising development during the last two decades is outlined and the changing notions of female beauty after Mao is examined, describing the resurfacing gender differences and the renewed importance of body and gender, together with the commodification of women and female beauty.

    Sammanfattning : This work concerns a waste electrical and electronic equipment blend of recycled plastics (WEEEBR), reprocessed from a low density thermoplastics batch (600 kg) by removal of non-thermoplastic contamination (1.2 weight % (wt%)). LÄS MER

  7. 5. Recycling and durability of PVC materials focusing on pre- and post-consumer wastes from building products

    Författare :Nazdaneh Yarahmadi; SP – Sveriges Tekniska Forskningsinstitut *(2016-12-31) SP – Sveriges Tekniska Forskningsinstitut; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Accelerated ageing; Activation energy; Annealing; Cables; Dehydrochlorination; Dismantling; DSC; Elongation at break; Emissions; Energy recovery; Flooring; Heat ageing; Lifetime; Orientation; Physical ageing; Plasticised PVC; Plasticiser depletion; Profiles; Recycling; Repeated extrusion; Residual stability; Rigid PVC; Sustainable building; Chlorination; Degradation; Durability; Mechanical properties; Plastic building materials; Plasticizers; Stabilizers agents ; Tensile properties; Molecular level; Polyvinyl chlorides;

    Sammanfattning : The potential for recycling various polymeric materials contained within buildings constructed in the late 1960s and 1970s in Sweden was investigated during the course of this work. Three residential blocks were studied to establish the quantity of materials available for recycling, to investigate the difficulty in and time needed for the dismantling of the buildings, the degree of purity of the materials, and the possibility of separating the materials.
