Soil reclamation. Synergy of glauconite and microflora

Reclamation of technogenic soils through the synergy of glauconite and microflora in a bioremediation system

Soil degradation due to industrial activity forms technozems – anthropogenically altered soils with a disturbed structure and critical concentrations of heavy metals.

Restoration of such areas requires not mechanical stabilization, but regeneration of the biological activity of the edaphotop. Our Institute’s methodology is based on the integration of glauconite into bioremediation cycles.

Mechanism of mineral-biological interaction

Glauconite (iron-containing phyllosilicate) has a cation exchange capacity that allows it to fix mobile forms of cadmium, lead, and zinc. This prevents their migration into groundwater and plant biomass.

According to the Institute’s patent, glauconite acts as a protective bioplatform for microbiota. The porous structure of the mineral eliminates osmotic stress and temperature fluctuations for hydrocarbon-oxidizing bacteria and nitrogen fixers. The introduced microflora colonizes the surface of the mineral, accelerating the destruction of organic pollutants.

Land reclamation and bioremediation through GREENODIN

The technology is implemented in GREENODIN organo-mineral complexes. Glauconite in the product acts as a prolonger of the action of microbiological agents.

Stages of restoration of man-made areas:

1. Sorption fixation to reduce the toxicity of the soil solution through the ion-exchange properties of the mineral.
2. Activation of the microbiocenosis due to the development of introduced strains in the pores of glauconite.
3. Humification, by catalytic formation of humic compounds with the participation of iron and magnesium in the mineral structure.

Expert’s comment:

• “We are replacing the concept of cleaning with the concept of restoring the ecological function of the ecosystem. The synergy of glauconite and microflora creates a self-regulating system on mining dumps. This is a circular model where the mineral matrix ensures the sustainability of bioremediation regardless of external stress factors,” — Timur Levda, a specialist in sustainable development.

Performance indicators for agricultural holdings

The use of glauconite according to the protocols of our Institute ensures the return of degraded lands to economic circulation:

• Reducing the fertility recovery period to 2-4 seasons.
• Activation of natural nitrogen cycles reduces the need for mineral fertilizers in subsequent stages of operation.
• Compliance with international ESG standards for biodiversity restoration and soil decarbonization.
