Abstract

Leachate management is one of the most important economic costs during the daily operations of a municipal solid waste (MSW) landfill. Classical landfill management techniques may produce a great volume of leachate that needs to be transferred to external wastewater treatment facilities which are usually located a great distance from the landfill site. If leachate is reintroduced inside the landfill under optimal conditions and the landfill is managed as a bioreactor, both economic and environmental benefits are obtained. This chapter shows an application of BIOLEACH, a new decision support model for the real-time management of municipal solid waste bioreactor landfills that allows to jointly estimate leachate and biogas productions. The model uses monthly local weather data and real waste chemical characteristics, so leachate and biogas productions are obtained accounting for actual conditions inside the waste mass. The bioreactor management strategy is followed, so leachate recirculated volumes are computed in terms of maximizing biogas production accounting for the specific water content conditions inside the landfill mass. A case study on a new landfill in Valencia Region (Spain) is shown. Results demonstrate the importance of accounting for optimal leachate management strategies in terms of reducing total leachate volume while maximizing biogas production during the landfill operational phase.
