  • Material and Energy Beneficiation of the Automobile Shredder Residues
    2013
    Co-Authors: Nour-eddine Menad, Ndue Kanari, Sylvain Guignot, Frédéric Diot, Lev Filippov, Fabien Thomas, Jacques Yvon
    Abstract:

    Although vehicles represent a main key of our modern society, they affect our environment via the energy and resource consumption, waste generation during their manufacturing as well as greenhouse gas emissions all along their use. Further, hazardous residues are produced at the end-of-life vehicles "ELV". After collection and dismantling, the remainders of the ELV are directed to Shredding operator followed by a series of mechanical and physical separations in order to recover the ferrous and non-ferrous metals. The residue of the Shredding Process, called automobile shredder residue "ASR" represents about 20-25% of the ELV. The ASR, while toxic enough to be classified as hazardous waste, could be considered as material and energy sources. The present study deals with the possibility of material and energy beneficiation of the ASR by its use in the metallurgical units. ASR samples from an European automobile shredder company were collected and subjected to the physical separation Process followed by a thermodynamic approach and isothermal batch tests to assess the reducing performance and energy capacity of the ASR hydrocarbon matter. Particular attention was devoted to the behavior of several residual and tramp elements (Cl, Pb, Cu, Zn) affecting the metallurgical Process and the product quality. Results showed that physical operations (screening, attrition, dry low intensity magnetic separation) lead to a selective extraction of the mineral part of the ASR which can be directed to the blast furnace unit. Direct reduction of hematite by the plastics contained in the ASR was obtained at 1000-1050 °C resulting into multistage steps of Fe2O3 converting into metallic iron. Multi-parametric analysis of the results suggests that the purified ASR can partially substitute raw materials used in pig iron and steel production.

  • Valorization of the automobile shredder residues by thermal route
    2012
    Co-Authors: Ndue Kanari, Nour-eddine Menad, Frédéric Diot, Lev Filippov, Fabien Thomas, Jacques Yvon
    Abstract:

    The automobile shredder residues “ASR” represents a heterogeneous material generated during the Shredding Process of the end-of-life vehicles “ELV”. The ASR, while reactive enough to be classified as hazardous waste, could be considered as a source of energy and reducing agents, since it contains an appreciated combustible hydrocarbon matter, especially plastics. In this context, the present work provides an alternative approach for the thermal valorization of the ASR in iron and steel making operations. Plastics and ASR samples from an European automobile shredder company were collected and their thermal behaviors were studied at temperatures lower than and or equal to 900 °C. Appropriated mixtures of these samples with iron oxides were isothermally treated between 300 °C and 1050 °C for different reaction times. Initial samples as well as solid reaction products were subjected to different analysis methods. The direct reduction of hematite into metallic iron, at 1000-1050 °C, by plastics and ASR hydrocarbons was proved. The reduction steps, the possible reaction mechanisms and the behavior of several tramp and harmful elements were also discussed. Experimental results and thermodynamic predictions suggest that the thermal route can be a promised choice for the valorization of the wasted organic materials. Thermal Processing overcome the difficulties and costly operations related to the ultimate removal of lead, zinc and copper compounds by physical means from these wastes. Reactions of chlorine, coming especially from PVC, with these metallic compounds generate their respective chlorides which are volatilized at relatively low temperatures leaving behind an appropriate matter to be introduced in different units of iron metallurgy.
