Company’s Faces: Tatyana Grekova and Lyubov Malysheva
Employees of the Gorky Regional Oil Pipeline Directorate (RPD) under Transneft Upper Volga have proved the efficiency of use of a pollutant-free peat-and-mineral hydrophobic self-disposing oil biosorbent in mitigating emergency oil and petroleum products spills on soil and water.
Cleanup of oil contamination is a challenging environmental task. Working as engineers at the Division for Environmental Safety and Rational Nature Management of the Gorky RPD, Transneft Upper Volga, we faced the fact that the methods applied to mitigate the consequences of oil spills do not fully solve the problem. Therefore, my colleague Lyubov Malysheva and I decided to look for more effective means to eliminate oil spills.
Tatyana and I worked jointly to assess the efficiency of use of mineral self-disposing biosorbents. The idea was to do without the stage of waste disposal in the process of cleanup of the oil spilled to water or soil. A usual sorbent absorbs oil, and then it has to be collected as waste and disposed somewhere. As a result, the cleaning turns out to be quite costly. While we wanted to simplify the whole thing, and we did.
The biosorbent is capable of absorbing oil and decomposing its complex hydrocarbon compounds into simpler ones, thus reducing the time required for the environment to get clean again. The oil was absorbed into the sorbent and was eaten by the microorganisms placed on top, as they feed on the hydrocarbons contained in the oil. All the resulting biomass is transformed into natural humus. That is, the process of waste disposal is skipped in this case. Our method is safe for the soil and the water. The microorganisms used are completely non-toxic, non-pathogenic, and do not represent any harm to humans, animals, fish or plants.
