A modern landfill - experiences from Fläskebo landfill, Sweden

Fläskebo is the first landfill in Sweden to be constructed entirely according to the national implementation of the European landfilling directive. It has only received waste with total organic carbon content below 10 %. The leachate of Fläskebo has been studied and compared to that from other Swedish landfills with the aid of multivariate data analyses and geochemical modelling. Concentrations of carbon and nutrients are very low. Salinity and metal concentrations were not generally higher than in other leachates. The conditions in Fläskebo were probably more oxidizing compared to classical MSW landfills and the landfill does not seem to go through the phases of a classical landfill. Multivariate statistical analyses in combination with geochemical modelling were valuable tools for understanding leachate behaviour and the interrelations between leachate parameters.
