Abstract: In recent years, fast economic growth combining with population expansion, domestic and industrial waste becomes a headache in waste management. Disposing of waste in a landfill remains a common practice in most countries. Hong Kong is adopting this method in handling waste disposal. Putting aside the environmental issues for the time being, land for dump sites becomes a mounting problem. According to the information given by the Environmental Protection Department of Hong Kong, the total amount of municipal solid waste disposed to legal landfills was 3.4 million tons per year. If this trend prevails, landfills will exhaust by 2015. Reducing waste and deriving waste management is desperate. Based on the above reason, the production of refuse derived fuel (RDF) from waste is one of the methods to extend the life cycle of landfill. In order to apply RDF in the Pearl River Delta region, an investigation is carried out. The study includes the technical aspects such as the heating value of RDF, production technique, emission control, chimney height assessment and location selection. In addition, the importance of waste to energy mode assessment with the best performance and minimal environmental impact by using life cycle analysis (LCA) are used. The second part of this dissertation is focused on the financial aspects. The cost estimation of production plant, cost of product and capital are analysed by scenarios assumption. In this paper, raw data are gathered from library research, review of literature of related topics, journals, statistical records and reference books. RDF covers a wide range of waste materials which have been processed to fulfil technical specifications mainly to achieve sufficient heating value. Co-incineration is favourable to apply in the Pearl River Delta region as heating value is below 20MJ/kg. Guangzhou is the best location to build up a RDF production plant in the Pearl River Delta region because the comprehensive level of economic and technology in Guangzhou is ranked 45%. The capital investment for setting up facilities is estimated to meet the market competition. Using RDF to generate electricity can utilize a portion of municipal solid waste and provides environmental and economical benefits.
