  2. 1. Studies on the Recovery of Secondary Antimony Compounds from Waste

    Author : Toni Karlsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Morphology; Thermolysis; Leaching; Municipal Solid Waste; Zinc; Metal Oxide Varistor; Cementation; Fly Ash; Recycling; Antimony;

    Abstract : The global supply of antimony is dominated by one country which has led the European Union to classify antimony as a critical raw material. Other than the rare-earth elements antimony has the highest supply risk. Therefore, a feasibility study on the recycling of antimony and antimony compounds is of great importance. READ MORE

  5. 3. Gamma irradiation in multi-cycle ABS recycling- effects on ABS properties and the recovery of antimony

    Author : Sandra Tostar; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ABS; antimony; gamma irradiation; recycling; WEEE; plastics;

    Abstract : Electronic waste, also called waste electrical and electronic equipment (WEEE), is the fastest growing waste stream in Europe today. The fast exchange pace of mobile phones, televisions and computers creates an important need to develop recycling areas to take care of, reuse and recycle these materials. READ MORE

  6. 4. Redox reactions and structure - properties relations in mixed alkali/alkaline earth glasses : The role of antimony oxides during the fining process- A structural study of copper(I) and copper(II)
