There were concerns that, because of the nature of this material, there was a potential for dioxin formation leading to increased emissions. This paper describes a comprehensive study into the recycling of steel coated with Plastisol, a material based on polyvinyl chloride. Results showed that the addition of OCS did not cause a significant increase in the emission of dioxin compounds. Dioxin emission concentrations were very low and generally within ranges previously obtained at other Corus UK steel-plants.
