The various kinds of high efficiency systems for waste-to-energy are developed and proposed. RDF (Refuse Derived Fuel) is included as one of these systems. In this paper, we compared a RDF incinerator system with a direct refuse incinerator system from the view point of environmental load and amount of produced energy in entire these life cycle. We applied LCA method to assess energy consumption, energy recovery, carbon dioxide emission volume, NOx gas emission volume and SOx gas emission volume. As the result, it became clear that the RDF system consumed more energy resources than the refuse incineration system, because the refuse contained much water (content of 60%) and it required a lot of burning oil to dry the refuse.
