  1. 1. Alternative reducing agents in metallurgical processes : Experimental study of thermal characterization of shredder residue material

    Författare :Samira Lotfian; Noureddine Menad; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Sammanfattning : Coal used in metallurgical processes can participate in reduction reactions to produce metals and alloys from oxides. Base metals production leads to generation of slag, which contains valuable metals that can be recovered and recycled. There are several options to treat the slag, depending on the metal content in the slag. LÄS MER

  3. 2. Development and Evaluation of a Filter-Bed-Based System for Full-Scale Treatment of Industrial Landfill Leachate

    Författare :Pille Kängsepp; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organic and inorganic pollutants; Landfill; shredder residue; vertical-flow filter bed; pond; leachate treatment; carbon-containing ash; peat;

    Sammanfattning : It is well known that nature offers an abundance of materials and processes that can be adapted in low-tech fashion, to fabricate systems capable of removing pollutants from wastewater. During the last decade, extensive basic and engineering research on such natural treatment systems have led to improvement of the quality of discharged wastewaters. LÄS MER

  5. 4. Can we go circular? : On the multifaceted challenges of facilitating shredder fines valorisation in the Swedish context

    Författare :Tharaka Gunaratne; Joakim Krook; Hans Andersson; Rajib Sinha; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In concomitance with the growing developments around the circular economy concept in the region, the resource recovery and recycling of industrial production residues is increasingly being envisaged in the European Union and its member states. The role of the recycling industry has become ever important in this context. LÄS MER

  7. 5. Valorisation of heterogeneous industrial residues towards a circular economy : A systems-oriented investigation on how to facilitate shredder fines valorisation in the Swedish context

    Författare :Tharaka Gunaratne; Joakim Krook; Hans Andersson; Jouni Korhonen; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Circular economy; Systems analysis; Valorisation; Resource recovery;

    Sammanfattning : In the context of circular economy in the European region the role of the recycling industry has become ever important. Shredder fines (or fines) is a heterogeneous fine-granular production residue of the shredding industry, and is currently disposed of. Shredder fines presents a disposal problem and incurs handling costs to the shredding industry. LÄS MER
