One of the achievements is a development of a system to capture organic chlorine contained in waste plastics as inorganic chlorine by means of external heating and superheated steam and wash the heat-treated waste plastics with water, producing dechlorinated fuel which can be used for cement calcination. The heat treatment process in this system was tested at a pilot-scale demonstration plant. The test results showed dechlorination was successfully accomplished, with 42% of the total chlorine in the raw material converted to inorganic compounds and 38% to volatile chlorine, while retaining the heat within the treated product. When alkali was added to the raw material in another trial, 90% or more of the total chlorine in the raw material was successfully converted to inorganic compounds, without producing volatile chlorine.
