The construction of controlled landfills, either for municipal or industrial wastes, is currently acknowledged worldwide as a 'social need". Indeed, today one of the main societal issues is the identification of an optimal means of disposing of the huge quantities of urban and industrial waste produced on a daily basis by individuals and factories. The task of environmental engineers is to design landfill systems capable to prevent any pollution to the water, the air, and the surrounding fauna and human life. In densely populated countries, the first problem to be solved is the location of the landfill. This social confrontation often leads to locate the landfill not in most geologically and geotechnically suited site, but in marginal areas which finally satisfy all the fighting communities. More and more geosynthetics are used to solve the problems associated with landfills located in marginal areas. The use of geogrids to construct steep reinforced embankments with the aim to increase the volume of wastes that can be disposed and at the same time to increase the stability of the wastes themselves, is getting more and more diffused. The paper describes the use of geosynthetics reinforced soil structures to increase the landfill volume with reinforced soil embankments. Some examples of structures already constructed, either for industrial or municipal wastes landfills, are described.
