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.
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.
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:
The use of glauconite according to the protocols of our Institute ensures the return of degraded lands to economic circulation:
Ecological breakthrough in combating desertification: artificial cultivation of biological crusts (biocrusts) in the deserts of the PRC. Accelerated bioremediation technology from AVELife.
Research on the transfer of space technology of the PRC (Chang’e mission) to combat land degradation. How continuous basalt fiber (CBF) fixes the Gobi and Takla Makan deserts.
Analysis of China’s large-scale eco-engineering program. Basalt fibers, artificial biocrust, and agrovoltaics in the fight against the Gobi and Takla Makan deserts by AVELife.
