In International DEA Symposium, Moscow, June 24-26 - Institute for Systems Analysis of Russian Academy of Sciences Sciences ; Global S. Consulting, Moscow, proceedings. p. 89-99.http://hdl.handle.net/10400.11/1484The present work evaluates the efficiency of collection, separation, valorisation and treatment of urban solid waste in the Urban Solid Waste Systems of Portugal by applying an econometric non-parametric technique: technical efficiency and cost minimisation of input needs were reached by the application of Data Envelopment Analysis. The data was obtained by requesting financial information for the year 2000. The sample covered almost 40% of the total population. This research aims to make a contribution to the evaluation of efficiency in the Urban Solid Waste Systems of Portugal.engUrban solid wasteData envelopment analysisEfficiency analysisjournal article
