The recycling process of waste plastics using coke ovens is now being studied. The effect of added plastic size on coke strength and coking pressure was investigated. The coke strength showed the minimum at the particle size of 10mm for polyethylene (PE) and 3mm for polystyrene (PS). The mechanism for this was explained in connection with the weak coke structure formed on the interface between plastic and coal. Furthermore, it was shown that the addition of powder PE increased the coke strength and the coking pressure due to the gas trap in the coal thermoplastic layer.
