Feedstock recycling of plastic wastes in cokemaking

Abstract

The carbonization of coal to produce metallurgical coke is an alternative route for the feedstock recycling of plastic wastes of different structures and origins. The effects of the composition of the plastic wastes on the thermoplastic properties of coal, coking pressure generation and the quality of the cokes produced at a semi-pilot scale are discussed. The plastic wastes studied were chosen because cover a wide spectrum in terms of polymer structure and composition (single and multicomponent wastes) in order to establish the right balance between coking pressure generation and coke quality parameters.
