“…These parameters include: physical properties of ASR, energy content and chemical composition of ASR, non ferrous elements contained in ASR, and the amount of ASR needed to maintain a continuous supply to a blast furnace. This material was tested in a pilot plant [12], and it was claimed that the temperature and atmosphere conditions characterizing normal blast furnace operation allow the complete destruction of organic compounds and avoid the formation of dioxins. Furthermore, heavy metals are dissolved in the hot metal and in the slag.…”

Plastic-containing shredder residue material has the potential to be used as an alternative reducing agent in nonferrous bath smelting processes. This would lead to not only decreased dependency on primary sources such as coal or coke but also to an increase in the efficiency of utilization of secondary sources. This calls for systematic scientific investigations, wherein these secondary sources are compared with primary sources with respect to devolatilization characteristics, combustion characteristics, reactivity, etc. As a first step, in this paper, devolatilization characteristics of plastic-containing shredder residue material (SRM) are compared to those of coal using thermogravimetric analysis. Proximate analysis has shown that SRM mainly decomposes by release of volatiles, while coal shows high fixed carbon content, which is reported to contribute to reduction reactions. To study the reduction potential of the evolved materials, composition of evolved off-gas was continuously monitored using quadrupole mass spectroscopy. The composition of volatiles shows H 2 , CO, and hydrocarbons which are known to have reduction potential. Therefore, it is essential that SRM would be used in a process that could utilize the evolved volatiles for reduction. Furthermore, to understand the potentials of different plastic materials as reducing agents, the devolatilization mechanisms and volatile composition of three common plastics, namely, polyethylene, polyurethane, and polyvinylchloride and their mixtures have been studied. The results show the interaction between the plastics within the binary and ternary mixtures. Similar phenomena may occur during devolatilization of SRM, which contains different type of plastics.

“…Not only the presence of these materials but the fluctuations in their levels in the feed [18][19][20][21] provides many challenges, themselves due to variations of types and ages of vehicles, additional scrap feed from white goods and light iron, [6,[21][22][23][24] and even different operating conditions at contractors supplying the feed. Adding to these challenges are the highly variable moisture content [12,18,21,22,24] and energy content [6,7,[25][26][27][28][29] of SR. Full information on all of these parameters is needed for the design of appropriate thermal processes. Summaries of their published values are thus provided in this paper.…”

A critical review of developments in the pyrolysis of automotive shredder residue

Worldwide, automotive shredder residue (ASR) is considered an increasingly problematic mixture of materials that needs the development of a processing solution.Pyrolysis is a process that has many advantages to offer, but despite many studies and developments in recent years at various levels of commercialisation, it is still generally considered unproven for this purpose. This paper critically considers developmental work published in the field, presents new results, and suggests that a major reason for the lack of development is the complexity of the landscape created by strong, competing, economic, legislative, environmental and commercial drivers, which in turn make it unclear which products and processes are optimal. This is made doubly complex by the natural variation in the material composition of ASR, with contaminants that can critically affect its potential fate to anywhere in the range from hazardous waste, to energy source, to useful raw material for major cement or steel industries.New data on critical factors such as levels of chlorine and metals in raw and pyrolysed ASR are presented, alongside a much-needed summary of previously published values from references that are often difficult to source. The summaries emphasise the variation in the material, but also indicate rough boundaries for values, which are needed for the design of any potentially successful process. 3It is suggested that the heterogeneity seen across ASR types implies that specialised processing of SR on its own is unlikely. It is pointed out that small-scale processes that could be suitable for local requirements should be considered for development as they could be able to optimise a process sufficiently to make it viable, e.g. specialised local waste streams of paper pulp and a particular fraction of SR.
