Transforming Construction Waste into Multifunctional Soil for Urban Green Spaces

Abstract

Cities have a limited ability to recycle waste, which could be improved by transforming certain construction waste into Technosols. Here, we show that Technosols made of fine earth excavated underground either pure or mixed with compost, can promote plant growth, soil biodiversity, and favor carbon storage. This solution could thus simultaneously supply a resource for local green spaces, reduce construction waste in landfills, and lessen topsoil removal from neighboring environments.
