Abstract

This paper reviews the role of sanitary landfills in current and future waste management strategies based upon the principles and the goals established by the European Framework Directive on Waste (2008/98/EC). Specific reference is made to studies of our research group regarding new tools developed to evaluate leachate production, taking into account the different characteristics of municipal solid waste (MSW). Laboratory leaching tests and a methodology proposed to interpret the results are described and discussed, as well as tools developed to estimate landfill leachate production. Residual flows produced by mechanical-biological treatment (MBT) plants, mainly Solid Recovered Fuel (SRF) and Stabilized Organic Waste (SOW), incineration and composting plants are considered in particular. Experimental results showed that the most suitable end-uses or disposal options for the outputs of waste treatment plants are site-specific and should be defined on the basis of a detailed characterization. The application of the model developed to assess landfill leachate production showed a very good agreement with field data.
