METHOD OF RESTORING TECHNOGENICALLY DISTURBED URBANIZED LANDS Russian patent published in 2024 - IPC B09C1/00 C05F17/05 

FIELD: ecology; soil treatment.

SUBSTANCE: invention relates to ecology and environmental protection and is intended for restoration of technogenic disturbed urban lands. Method involves application of an artificial soil mixture with plant seeds onto a technogenically disturbed surface, watering with water and coating with a polymer film, which is removed when even sprouts appear. Composition of the artificial soil mixture includes loams, clays, citrogypsum, zoocompost of black soldier fly, plant remains in the form of leaves and grass, wastes of wet magnetic separation of iron ore and sand. Volumetric geogrid is used, which forms a structure of hollow cells, into which an artificial soil mixture is filled with the following content of mass fraction of components, wt.%: clay – 15–20, loamy soil – 15–20, citrogypsum – 10–15, black soldier fly zoo compost – 10–15, plant residues in the form of leaves and grass – 10–15, wastes of wet magnetic separation of iron ore – 5–10, sand – the rest.

EFFECT: method provides reduction of terms of restoration of vegetation cover on technogenically disturbed urbanized lands without limitation of field of application with simultaneous expansion of composition of raw materials for its production.
