Hazardous waste is also becoming more important as opportunities for industrial waste recycling are extended. Some hazardous industrial wastes that contain many inorganic materials and heavy metals can be reused as resources: Heavy metal recovery, heat energy, etc. To facilitate the waste-to-energy system, waste generation characteristics should be defined and managed by analyzing hazardous material content. This study examines the inorganic materials (Pb, Cu, As, Hg, Cd, Cr6+, CN, Ni, Zn, F, and Ba) of industrial wastes and the generation process (case of the Korean Standard Industrial Classification) using Absolutely Hazardous (AH) Waste Lists (LoW and EU). In particular, manufacture classification was a main waste generation process (82% for “AH”). Moreover, these 10 components (Pb, Cu, As, Hg, Cd, Cr6+, CN, Ni, Zn, and F, but not Ba) are compared with the regulatory limits on heavy metals in soil: Hg and As must be under the limit of the 3 Level (0.3 ~ 7.3 mg/kg).
