One of the core areas in the environmental protection activities of TATNEFT Group is to reduce the man-made load on the environment by reducing the specific indicators of waste generated from production and consumption. The Company has developed a comprehensive system for selective gathering and processing of waste from production and consumption, and using these as raw materials to produce commercial products.
In 2019, TATNEFT Group generated 119 thousand tonnes of waste (in 2018 - 101 thousand tonnes), including oil sludge (III hazard class) 23.4 thousand tonnes (in 2018 - 25 thousand tonnes). 9.8 thousand tonnes of wastes were used (in 2018 - 13.7 thousand tonnes), 4.4 thousand tonnes were neutralized at the production facilities of TATNEFT Group, including oil sludge 0.1 thousand tonnes (in 2018 - 0.095 thousand tonnes). 111 thousand tonnes were transferred to third-party enterprises, of which 23.3 thousand tonnes were oil sludge.
At the waste processing site of the vulcanization shop of LLC Nizhnekamsk All Steel Tire Plant LLC, 876.993 tons of rubber-containing waste, and 586.728 tons of polyethylene waste were processed in 2019.
The reasons that caused increase in waste in 2019 were:
- reconstruction of the preparatory shop and expansion of the production of all-steel tires at OOO Nizhnekamsk AST Plant;
- cleaning operations on 2 averaging ponds and a containment pond from bottom sediments at JSC Nizhnekamsktekhuglerod;
- commissioning of new units at JSC TANECO.
Of the total amount of waste generated in 2019, 67% were hazardous, i.e. belonged to 1-4 hazard classes, 33% were non-hazardous.
Hazardous waste management activities are conducted on the basis of licenses granting the rights to carry out activities on collection, transportation, processing, disposal, neutralization, and placement of waste of I-IV hazard classes, (licenses) issued by the Federal Service for Supervision of Natural Resources (Rosprirodnadzor).
Drilling Waste Management
The Company has a guideline document “Technological Regulations for Drilling Waste Management Process during Well Construction”, which establishes common requirements for managing drilling waste resulting from well construction, usage and subsequent liquidation of waste accumulation sites at drilling location.
All waste generated during well drilling by contractors is the property of the Contractor.
Unique Landfill for Industrial Waste
A unique industrial waste disposal site was commissioned at the TANECO Complex, there is a reliable impervious screen on the bottom that prevents any possibility of biological and chemical contamination of adjacent territories, groundwater, and ensures the capture of leachate which is then transported to the treatment facilities at the Refinery and Petrochemical Plant.
