Table 1 shows the comparison of quality standards for solid fuel products. In order to satisfy the quality standards of solid fuel products (Appendix 7 of the Resource Recycling Act), the applicant must also satisfy the criteria of water content, ash, chlorine and heavy metals (Pb, Cd, As, Hg). In order to confirm the characteristics of the solid fuel, it was requested by the Korea Feed Mill Association and the results are summarized in Table 1, including the low calorific value.

At this time, the content of the waste plastic (LDPE) contained in the recycled waste was different from each other to determine whether the solid fuel produced meets the criteria of water content, ash, chlorine and heavy metals (Pb, Cd, As, Hg).

 Resource Recycling Law Compared with the solid fuel product quality standard in Annex 7, the mixing ratio of waste plastics of mixed wastes of 10% or more was found to meet the criteria under all conditions. The maximum content of ash and chlorine was 9.45 wt.% And 1.17, respectively. As a result of wt.%, it was significantly lower than the quality standard. In the case of heavy metals, 2.33 mg / kg of lead, 0.38 mg / kg of cadmium, and 0.52 mg / kg of arsenic appeared to be the maximum values, and thus, it was confirmed that they were suitable for commercializing the solid fuel produced through the manufacturing apparatus.
