Efecto de suelos en la degradación anaerobia de residuos sólidos municipales

Abstract

Landfills might be regarded as a necessity, and it is foreseen that they will be still used in the short and long term. Landfilling is bound to remain, regardless of how conscientiously other strategies are practiced, such as recycling, reducing and reusing; there will always remain a fraction with no other alternative than landfilling. In Scotland (UK), landfilling managing strategies are changing to comply with the European Community Landfill Directive (1999). The new legislation prevents organic matter from being landfilled, and waste composition is anticipated to change. Therefore, it is urgent to investigate the effect of any other organic component in a landfill, for instance, the intermediate soil cover (ISC). We propose that the inclusion of soil as ISC in the municipal solid waste (MSW), allows for the establishment of an earlier anaerobic fermentation. Thus, the aim of this work was to test the effect of the inclusion of 20% of soil in the MSW anaerobic degradation performance parameters.
