Abstract

In this work, a detailed technical-economic analysis of a fluidized bed based waste-to-energy system for disposal of paper manufacturing sludges has been carried out. Specific reference is made to a case study represented bythe largest plant in Italy producing recycled paper, with a daily sludge output of about 52 t. The adopted plant has been sized for a nominal capacity of 140 t per day also allowing the progressive elimination of sludges accumulated in a previously utilized landfill, giving a nominal electrical power output of 3.5 MW. The main plant sections have been described and the adopted technical solutions have been outlined. A detailed process and equipment characterizationhas been carried out leading to a thorough evaluation of capital investment, operating costs and revenues. A differential analysis has been performedwith respect to the alternative solution represented by the disposal of untreated sludges in an external landfill in order to highlight the savings obtainable. The economic profitability of the investment has been evaluated regarding several performance indices. The economic evaluation has been completed by a sensitivity and risk analysis in order to assess the effects ofuncertainties in the economically significant parameters. Adopting most probable values, the savings obtained with the considered waste-to-energy system are evaluated in the 15-20 million Euro range during the estimated plant life of 15 years with a foreseen pay back time of 4 years. Moreover, manyenvironmental benefits result such as the remediation of existing landfill, the avoidance of new landfills opening and very low air pollutants emissions. (C) 2001 Elsevier Science B.V.
