Recycling of SLF through hightemperature gasification

Recovery of the light fraction from automobile shredding (SLF) is complicated by chlorine (Cl), which contributes to the formation of highly toxic dioxins from incineration. Copper (Cu) and other metals have been shown catalytically active in the dioxin formation. Recent advances in waste management enable the production of a cleaner fuel fraction from SLF, where much of the metals (e.g. Cu) have been removed. Gasification has in some studies been identified as a suitable recovery option, because dioxin formation seems to be reduced compared to incineration. This pre-study therefore aims to experimentally characterize the oxygen-blown high-temperature gasification of SLF in pilot scale. Measuring and comparing the amount of dioxins from both combustion and gasification will be carried out to clarify the differences between the two conversion technologies. The project will also identify appropriate applications and end users of synthesis gas from SLF gasification.
