As part of the construction of a recycling-based society and responding to climate change, necessity for recy-cling waste plastics to soild fuel generated and incinerated in the workplace and the construction field have been risen. For the production of solid fuel based on waste plastic, we configured the network to maximize the resources of waste plastic in the area at first. In addition, basically evaluating basic characteristics of the waste, mixing ratio, ratio of chlorine-contained have been carried, as well as the process development for the production of RPFs and the field test. Developing typical waste categories (10 types), moisture, volitile, ash content, elemental analysis, calorie value test and heat analysis (TG-DTA, DSC) were carried out in order to evaluate the thermal potentials. screening the samples (16 types) and chlorine content (using SEM-EDX) were performed to assess the risk of HCl generated in the incineration of RPFs. Resultly, Moisture content is about 29.8 to 36.0%, ash content 4.0 to 13.8%, combustible content is 52.5 to 66.3%, calorific value was 4,834.7~7,776.9 kcal/kg. As a result of molding test of RPFs with plastic waste, the calorific values are 1 to 2 grade.
Contents of moisture and ash are satisfied to the national standard. Not detected are mercury, cadmium, arsenic,and lead content is about its criteria. |
