The main objective of the project is to develop and enable the market application of a new soil structural substrate based mainly on construction recyclate and pyrolysed sewage sludge. Another objective of the project is to determine the variability of the chemical properties of the recycled materials used and to develop a tool for optimising the substrate composition based on the variable characteristics feedstock contamination. The project focuses on experimental verification of the effect of the substrate on vegetation growth and runoff quality, determination of the hydrophysical properties of the substrate and its LCA. The project includes economic evaluation of production and distribution, development of a commercial scale production process and the introduction to Czech market.
