BIORECULAT – polymer covering for industrial waste land reclamation without application of topsoil.

BIORECULAT - is a stable elastic covering made from substratum and polymer obtained when applying water polymer emulsions covered on the surface of waste lands.

• an express method for stabilization of industrial waste lands;

• an universal means for vegetative erosion control (against soil drifting, soil washing, soil lifting frost);

• lasting covering that provides stabilization of substratum hydrothermal behavior, formation of plant cover with stable high productivity, intensification of microflora activity and, therefore, acceleration of soil-formation processes at rehabilitation of waste lands;

• a safe means for protection of root layer against industrial impact factors, which enables to rehabilitate vegetation under chemical and radioactive pollution;

• a perspective way for yield improvement of agricultural lands.

• HIGH ANTIEROSION STABILITY

• GOOD FILTRATION ABILITY

• AIR PERMEABILITY

• RADIATION RESISTENCE

• BIODECOMPOSAB1LITY

• ENVIRONMENTAL SAFETY

• mechanical strength, kg/cm²                                                                  > 18

• water permeability, mm/min                    4-12

• long durability, year                                >6

• stability against seasonal temperature changes, from - 40 to + 40 °C  

• reduction of temperature changes amplitude during vegetation period in root layer                                     1.5—3.2°C

• increasement of soil moisture content                                                                                                     30—50 %

• increasement of biological productivity of perennial herbs within the area under industrial factors impact        50—70 %

• increasement of yield of grasses on agricultural arable lands                                                                      20—30 %

BIORECULAT improves the ecological background of root layer of waste lands, protects against industrial pollution, thus, activating regeneration forces of nature and improves soil stability against industrial pollution. Activation of nature’s self-restoration forces promotes afast formation of soil fertility.

Polymer coverings are efficient being used both as under different types of pollution (intensive radioactive, hydrocarbon contamination, soil contamination with heavy metals) and as at different natural objects in different climatic regions which is evidence of their multi-purpose character.

Kola Peninsula has vast reserves of useful minerals, their mining and processing is accompanied with formation of mine waste lands.

Tailing dumps of AS "Apatit" with their nearly 4000 hec area are an intense source of dusting. Before stabilization the erosion processes involved tens of million tons of dust annually. Creation of vegetative cover on the slopes of tailings has solved the problem of dust storms for Apatity-city.

Rehabilitation of soil-plant cover technology with application of BIORECULAT polymer covering has become the background of a "Complex program on dust suppression aimed at reduction of radioactive dust transfer" during the liquidation of consequences of the accident at the Chernobyl NPP. Under the given technology the plant cover has been rehabilitated on thousands of hectares of stripping and deactivated areas within the Chernobyl NPP, which made the radionuclide amount less in the zone air by two-orders of magnitude.

The technology has been recommended to be used at development of gas deposits in the North of the Western Siberia for marginal lands, as the most ecologically, technologically and economically efficient. Rehabilitation of plant cover after deep prospecting drilling by the Tambey expedition has shown that plant cover under polymer covering is efficient against thermo-erosion. Stability of operating facilities besides solving environmental problems can also be provided.

Reclamation cost with polymer covering is ten times less than recultivation with application of topsoil.

Technological regiments for reclamation of plant cover of waste lands contain complete complex data: characteristics of reagents; technological regimes for production of working solutions; requisites of reagents producers; requirements for reagents transportation and storage; requisites of producers of special equipment and its characteristics.
