The application of RDF also can promote recycling-based society and reuse of energy. In this study, an air resource co-benefit model was established to assess overall social cost-benefit of HDP and GHG reduction by individually converting environmental cost, pollutant treatment cost and health cost plus the investment and the operating cost of the model ,the saving cost of fuel to the cost-benefit. In this article, the study case one compares the application of municipal solid waste RDF, including production and combustion of RDF, to direct combustion of municipal waste. The study case two, on the other hand, assess the overall social cost-benefit of municipal solid waste RDF that used as an aidded fuel in cement Rotary kiln. In the study case one, the treatment amount and properties of municipal solid waste are calculated according to average amount of Incineration treated garbage, i.e. 4,278,545 ton/yr, during 2002 to 2006 in Taiwan. The operational parameters of the RDF production were cited from the study article of Industrial Technology Research Institute. In the study case two, the used amount of the municipal solid waste RDF in cement Rotary kiln to partially substitute coal as an aidded fuel was assumed as 1.0% total heat value of coal. Finally, the efficiencies of policies were also discussed according to the results of study cases one and two. The results can provide industry and government as a reference of policy which can simultaneously consider economics, environment protection, ecology and society. The result of case one shows that comparing to the direct combustion of municipal solid waste, the RDF application of municipal solid waste will decrease 2,588,458,181 NT dollars of overall social cost-benefit and decrease 3,087,286 man-day of life for Taiwanese. The application of per ton municipal solid waste RDF will increase overall social cost-benefit 604 NT dollars in comparison with direct combustion of municipal solid waste. Therefore, it is not advised that municipal solid waste is converted to the RDF as a substitute fuel. For the case two, the result show that the application of municipal solid waste RDF as an aidded fuel in cement Rotary kiln increases overall social cost-benefit 29,222,471 NT dollars, but decreases 175,140 man-day of life for Taiwanese.
