The overall target of the proposal is to develop the required customised technologies and materials for the valorisation of PRS and the synthesis of the Engineered Soil, to demonstrate their applicability at pilot scale and to assess the performance of both VSM and engineered soil according to the relevant European standards and legislation.

Due to the unique properties of the selected industrial minerals, their integration with PRS will result in PRS stabilisation, and therefore the VSM will present minimum environmental risk. The selected industrial minerals will be properly processed and modified, in order to increase their effectiveness to the specific PRS, maximizing thus the desired stabilisation level. Furthermore, VSM is a suitable raw material for the construction and restoration of landfill sites and abandoned inactive quarries. The aim is the development of a stable quality Engineered Soil, through mixing of VSM with suitable soil amendments, with engineered properties for cost effective use in various development stages of landfill construction and restoration. Due to its tailored properties, the Engineered Soil will be able to substitute much larger quantities of the unstable quality materials currently used in landfills for the creation of the various layers.
