  • Recycling Options for Mixed Plastics in Automotive Shredder Residues

    Waste production (ASR) from shredding of automobiles is a major global problem. The current method of disposal via landfilling is unacceptable due to environmental concerns and high cost. This project focuses on the evaluation of competing technologies for recycling automotive shredder residues and in helping solve this industrial problem by analyzing feasible solutions for implementation. The ...


  • Automotive Shredder Residue (ASR) - From Waste to Products

    The paper will explain WESA-SLF, a dry-mechanical process to treat ASR with the aim to achieve usable products, mainly organic materials, metals, and minerals. Detail information will be given about the first plant for processing 4 tons per hour ASR which had its start up end of 1999. The experience with the first months in operation as well as with the quality of the products and the influence ...

  • Mechanical treatment of automobile shredder residue for its application as a fuel

    Enforcement of the Automobile Recycling Law in Japan requires utilization of automobile shredder residue (ASR). However, the high contents of copper (~5%) and chlorine (~1%) in ASR stand in the way of practical application. We studied methods for the removal of copper and chlorine from ASR so that it could be utilized as a fuel. By compression of the ASR for solidification with an extruder, the ...

  • LCA of innovative technology for energy production from automotive Shredder Residue

    Automotive Shredder Residue (ASR) is a problematic waste material remaining after shredding and recovery processes of End of Life Vehicles (ELV). Its heterogeneous grain size and composition make it difficult its recovery or disposal. While ASR accounts for about 20‐25% of the weight of an ELV, the EU's ELV Directive (2000/53/EC) requires that by 2015 a minimum 95% wt. of an end‐of‐life ...

  • Automobile Shredder Residue (ASR) destruction in a plasma gasification reactor

    Test results on Automobile Shredder Residue (ASR), or car fluff, demonstrated destruction efficiency and safe conversion to synthesis gas and a glass residue, in a plasma gasification system. The synthesis gas consists primarily of hydrogen and carbon monoxide in the range between 20 and 22 vol-% respectively, or 45 and 55 vol-% dry basis, when corrected for nitrogen. In dry reforming operation, ...

  • Separation of Nylon 66 (PA 66) From Automotive Shredder Residue (ASR) Plastics by Flotation

    Plastics are the most valuable component of the automotive shredder residue (ASR) waste material making up 30% of the total weight. One promising separation technique, which is able to selectively recover the plastics from ASR, is flotation. It has been demonstrated for a synthetic PA66/ABS/PC system that nylon 66 (PA 66) can be selectively separated by caustic treatment and addition of alcohol ...


  • Automotive Shredder Residue its Application as a Reductant and Fuel in the Blast Furnaces of the Steel Industry

    Each year approximately 12 million automobiles, which have reached the end of their useful lives, are shredded in North America for the recovery of steel and other metals. Along with the metals the shredding operation produces a by-product known as autoshredder residue (ASR). ASR is a diverse mixture of organic and inorganic materials such as plastics, textile fabrics, glass etc.North American ...


  • Investigation of Pilot-Scale Experimental Pyrolysis Plant for the Treatment of Automobile Shredder Residue: Preliminary Results

    Abstract The main objective of the present research work is to evaluate both the process performance and characteristics of the products obtained from the treatment of automobile shredder residue using a pilot-scale experimental pyrolysis plant operating under different load and varying process temperature. ASR samples used for the treatment, solid and liquid by-products obtained and syngas ...


  • Axion waste processing plant training case study 3 – Operators team at automotive shredder residue recycling plant

    Challenge: The recovery process was a unique and complex automotive shredder residue recovery plant. There was a wide range of expertise within the trainee group. Some trainees had worked within the industry for over 10 years, whilst others had worked only 3 months. Plant modification work on site prohibited access to the machinery that the training ...

  • Austin AI QXR-M – Technology to improve metal recovery from non-ferrous residues

    Existing technology has been used for some time to separate light non-ferrous alloys from heavier non-ferrous alloys; however, over the past three years, there is a significant added value in performing additional separations to recover specific high dollar alloys. Examples of such are separating pure copper from copper alloys (brass and bronze) or wrought from cast aluminum. The only way to do ...

  • Report: Recycling of flame-retarded plastics from waste electric and electronic equipment (WEEE)

    Shredder residues produced in plants processing waste electric and electronic equipment are excluded from material recycling due to a variety of polymeric materials and the presence of brominated flame retardants (BFR), which might contain banned polybrominated diphenyl ethers or toxic polybrominated dioxins and furans (PBDD/F). Herein we present a technological approach to transfer a significant ...
