“…The intensities of some peaks in fractions D and E were reduced after the recovery. This may have been due to the suppression of material crystallinity after the recovery of heavy metals (Shibayama et al, 2006). Thus, the results of the present study clearly confirmed that the recovery of heavy metals with distilled water at pH 2 changed the structure of the ASR.…”

Automotive Shredder Residue (ASR), a waste when metals are mostly removed from end-of-life vehicles, has constituents similar to municipal solid waste (MSW) consisting of plastics, rubber, textiles, and some metals. The processing of ASR is a challenge due to its heterogeneous nature, making feeding to a reactor difficult. In this work, a new procedure of ASR pretreatment is proposed to bring particulate nature in the sample for easier feeding during pyrolysis. The thermal breakdown characteristics of the pretreated ASR solids under slow pyrolysis conditions were assessed in a thermogravimetric analyser following the International Confederation for Thermal Analysis and Calorimetry (ICTAC) kinetics committee recommendations. The effect of particle sizes and heating rates were studied at temperatures up to 800 °C at different heating rates of 2, 5, and 10 °C/min for three particle sizes, 38–63 µm, 63–90 µm, and 90–106 µm, and the kinetic data were derived. The volatiles emitted during pyrolysis were characterized by Diffuse Reflectance Infrared Spectroscopy (DRIFTS). We also developed an algorithm for the selection of heating rate during the pyrolysis of the pretreated ASR. The DRIFTS results, kinetic data, and heating rate for the selected particle sizes are useful for the development of a pyrolysis process for pretreated ASR.

“…Different kinds of processes could be used to recover metals from industrial wastes, but hydrometallurgical processes showed several advantages such as cost effectiveness and flexibility [2,3]. Concerning metal recovery from wastes, Yoshida et al [4] investigated direct copper recycling, while Shibayama et al [5] recovered zinc and copper from fly ash after combustion by distillation, precipitation and cementation.…”
