Resumo: An investigation of the potential of Maltese Municipal Solid Waste (MSW) for energy recovery is carried in this work together with a preliminary assessment of the corresponding economic and land use impacts. MSW composition data was collected to evaluate the waste combustion enthalpy. Data from 1997 to 2010 allowed the conclusion that an incinerator with a capacity of 32,500kg/h can treat all the waste expectably generated in Malta during next 20 years. The thermodynamics of the steam cycle combined with elemental analysis were applied to study the contribution for power (PG) and Combined Heat and Power (CHP) generation. The thermal energy was analyzed assuming its use in desalination. The best scenario considered corresponds to a potential electric power of 10 MW (PG) or to a maximum 4.8 million m3/year of desalinated water combined with and 7.25 MW (CHP). It was concluded that incineration and CHP have the greatest potential to maximize revenues, due to the optimal combination of heat production and electricity generation. Finally, a calculation of the savings in land use due to the MSW incineration implementation was performed. Those savings could represent from 13,500 to 17,000 m2 per year, a decisive benefit for Malta.

The work would not have been possible without the support of various individuals and institutions in Portugal and in the Maltese islands. In Portugal, we are grateful for the information provided by LIPOR - Central de Valorizacao Energetica, at Maia, which allowed us to validate the incineration data gathered in the literature. Our sincere thanks are also addressed to Prof. Toste de Azevedo, Viriato Semiao, Zdena Zsigraiova, Gilberto Tavares and Rui Martins, of the Mechanical Engineering Department at the Instituto Superior Tecnico, who helped us with the thermodynamic calculations and with other important incineration related information. We acknowledge the help of Prof. Godfrey Pirotta, Edward Mallia, Tonio Sant and Maria Attard of the University of Malta for their availability to explain and contextualize the islands' energy and environment policies. Finally, the assistance of WasteServ Malta Corporation, which provided actual information about MSW generation and further details about the Maltese waste management system, should also be acknowledged.ElsevierPergamon Press Ltd.Universidade do MinhoPirotta, F.
