The DURAGEOS project - Durability of geosynthetics used in landfills

Abstract

The DURAGEOS project studies the ageing mechanisms of geosynthetics (HDPE geomembranes and GCLs) in non-hazardous waste landfill facilities under the combined action of mechanical stresses, microorganisms and/or oxygen in connection with mass transfer. The physico-chemical and mechanical features of model and commercial geosynthetics aged in the laboratory allow the development of a kinetic model of prediction of the lifetime coupled to a model of material transfer. As part of this project, the models will be validated through geosynthetics sampled on landfill sites. Ecotoxicological risks and external environmental costs will be assessed.
