Abstract

Waste management is one of the current challenges of the Society because of the growth of the world population, the improvement in the quality of life, the increase in the size of cities and the changes in both consumption and style life of citizens. In this way, more and more wastes are generated. It is estimated a 70% n increase for the year 2050, reaching 3.4 billion tons of municipal solid wastes (MSW) (1). A good waste management is essential to protect the environment, the health, and the quality of life in the future. Therefore, it is important to minimize the impact of waste on the environment. Current European policies and legislation (Framework Directive 2008/98/EC; Law 22/2011) are based on promoting the reduction, reuse, recycling,and recovery of wastes, moving from a linear to a circular economy. However, despite the efforts made, more than 50% of the wastes generated in Spain still ends up in controlled landfills (2). In landfills, several chemical and biological degradations occur which, together with the percolation of rainwater, generate a residual effluent with a high pollutant load, called landfill leachate (LL)...
