    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; End-of-Life; Scarce Metal; Material Flow Analysis; Vehicle; Technological Innovation System; Car; Critical Material; Recycling;

    Sammanfattning : There are currently a billion cars in use worldwide, and car design trends point at increasing variety in material utilisation. Cars today contain several types of steel and aluminium, an assortment of textiles and padding materials, and an increasing amount of polymers and scarce metals. LÄS MER

  3. 12. Effects of Simulated Recycling on Polyolefin Materials

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

    Sammanfattning : 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. LÄS MER

  4. 13. Reverse Logistics Systems : an Interorganisational Perspective, Focusing on Paper Recycling

    Författare :Maria Huge-Brodin; Sten Wandel; Helén Anderson; Susanne Hertz; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reverse Logistics; Recycling; Paper; Interorganisational; Case studies;

    Sammanfattning : The purpose of the study is to describe and analyse reverse logistics systems. The study is a qualitative case study, and the main case comprise three actors: a supplier of recycled paper; their customer, the paper mill, and the transport provider linking the customer and supplier. Reference cases are recycling electronics and recycling cars. LÄS MER

  5. 14. Recycling of CIGS solar cell waste materials

    Författare :Anna Gustafsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Hydrometallurgy; Pyrometallurgy; CIGS; Recycling; Solar cells;

    Sammanfattning : The increased interest in solar power over the last few decades has led to a constant development of existing and new types of solar cells. One type of solar cell that is making advances on the global market is copper indium gallium diselenide (CIGS) thin film solar cells. LÄS MER

  7. 15. Sustainable Recycling of Spent Lithium-ion Batteries : An In-situ Approach for Recovery and Alloying of Valuable Metals

    Författare :Safoura Babanejad; Hesham Ahmed; Charlotte Andersson; Ari Jokilaakso; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Li-ion battery; black mass; Recycling; Pyrometallurgy; modeling; Process Metallurgy; Processmetallurgi;

    Sammanfattning : A large number of Li-ion batteries used today will reach their End-Of-Life (EOL) in a few years. After their EOL, the recovery of their precious elements is required. By applying physical separation, a fraction with fine particle size is left behind which is known as Black Mass (BM). LÄS MER
