Environmental Geotechnics deals with a wide variety of applications, such as the characterization of polluted
sites and landfill waste, the design of containment systems for subsoil pollutant control, radioactive waste
disposal, geo-energy exploitation and bacteria-driven soil modification, among others. In order to obtain reliable
and effective predictions of the actual behavior and performance of these very complex systems, theoretical
and experimental research and advanced design procedures need to take into account the coupled hydro-bio￾chemo-mechanical phenomena that occur at very different scales. Future progress in the scientific state of the
art and substantial advancements in standard practices will therefore be closely related to the development
of shared knowledge among different disciplines. The extension and refinement of theoretical modelling and
the experimentation capabilities stimulated by geo-environmental applications more in general provide the
framework for substantial advancements in the soil and rock mechanics fields
