Review of the last two decades experiences of technosols construction for urban greening

With the rise in urban population and the urban sprawl come demand for solutions to offset the environmental burden in cities. Green infrastructures are interconnected urban spaces that provide multi-ecological functions and that mainly rely on their soils component. However, because of either the consumption of such natural resources as neighboring topsoil or the poor design and implementation of soil materials, actual approaches are questionable.Constructed Technosols, consisting of rational associations of organic and mineral wastes, are artificial soils designed to meet specific requirements. Such innovative solution based on circular economy may appear as valuable contribution to susta…
