6.2. Biodiversity of the Caspian ecosystem
The conservation of biodiversity is a prerequisite of the welfare for present and future
generations. Therefore, the protection and conservation of the unique biodiversity in the
Caspian region is a top priority for NCOC in global sustainable development.
Biodiversity Action Plan
The conservation of biodiversity in the Caspian Sea and its coastal areas is an integral
part of NCOC activities under the NCPSA. Due to the completion of onshore and offshore
construction and transition of the Project for Kashagan development to the stage of
Experimental Development (EP), the decision was made to update the Biodiversity Action
Plan (BAP). In 2020 NCOC completed the update of the BAP.
The main objective of the BAP is the conservation and improvement of biodiversity
through identification and proactive management, minimization of potential impacts and
operational risks at the EP phase.
In early November 2020, the Plan was presented to the public. It provides a set of actions
for biodiversity study and conservation and raising the public awareness and involvement
about biodiversity of the region.
The BAP planned actions cover three areas:
- 1. Study of offshore and onshore biodiversity for its further conservation;
- 2. Use of advanced practice;
- 3. Support of environmental programmes.
Study of offshore and onshore biodiversity
The activities aimed at biodiversity study and conservation include:
- Regular monitoring of onshore and offshore environmental parameters as part of
- Surveys of the Caspian seal population.
- Birds observations, environmental surveys in the Zhayik river;
- Development of a biodiversity geographical information system;
- Landscaping works in the OPF «Bolashak» sanitary protection zone;
- Development of a sensitivity map for the North-Eastern part of the Caspian Sea;
- Surveys of the artificial island colonization with bottom organisms;
- Release of fish youngsters from the sturgeon hatchery into Zhayik-Caspian water
Use of advance practice
This area includes use of advanced technologies for biodiversity study
- Use of unmanned aerial vehicles for wildlife surveys;
- Multispectral survey of the Caspian seal population;
- Creation of a sturgeon breeding scientific centre.

The actions in the Plan envisaged for the period 2020-2025 can be amended and
supplemented, if needed, depending on the current conditions
Caspian seal Pusa caspica (Gmelin, 1788) is the only marine mammal and the endemic
species inhabiting the waters of the Caspian Sea. The most important zone for the
Caspian seals is the northern part of the sea, where they concentrate from autumn to
early summer for breeding, which is one of the most significant and vulnerable stages of
their life cycle.
In recent decades, the natural changes in the ecosystem of the sea (air and water
temperature increase, sea level drop, reduction of ice coverage in winter, etc.) have
been recorded, which result in changes of the marine environment and the condition
of the Caspian aquatic organisms. The Caspian seal population is in a critical situation.
Its number dropped in 2005-2012 from 1 million species at the beginning of the 20th
century to 150,000 species according to the Caspian International Seal Survey (CISS).
Since 2008, the Caspian seal has had an “endangered” status on the Red List of the
International Union for Conservation of Nature.
Scientists of the Pre-Caspian states register a drastic decline in the seals number and
the threat of their extinction and proposed to the governmental bodies to include the
Caspian seals in the National Red Books. In March 2020, these endangered species were
included in the Red Book of the Russian Federation. At the end of November 2020, the
RoK Governmental Resolution No.746 dated 9 November 2020 came into force and
included the Caspian seal in the List of Rare and Endangered Species of Animals (the Red
Book of the Republic of Kazakhstan).
Earlier in 1993, the Caspian seal was included in the Red Book of Azerbaijan, in 2011 – in
the Red Book of Turkmenistan. At the initiative of Iran in 2017, the Caspian seal is
in Annexes I and II of the Convention on the Conservation of Migratory Species of Wild
Animals (Bonn Convention).
As in all previous years, starting from 2005, NCOC conducted winter monitoring of seals
in 2020 involving Kazakh experts (Kazakhstan Agency of Applied Ecology LLP (KAPE))
and supervised by scientific-research institutes (Russian Federal Research Institute for
Fisheries and Oceanography (VNIRO), Volga-Caspian branch of the VNIRO).
The monitoring was performed from Mangystau-3 and Tulpar icebreakers carrying cargo
between Bautino Offshore Supply Base and Kashagan field with the direct involvement of
experts – seal observers. In 2020, the monitoring took place in the period from January
29 to February 23.
In addition to scientific data collection, on-board observers help the ship captains to avoid
seals, in compliance with the mitigation recommendations developed by marine mammal
experts at the start of the project. This is complemented with helicopter reconnaissance
flights over the seal concentration areas. The reconnaissance results are reported directly
to the icebreakers, where captains and seal observers define the safest navigation route.
Recently, the thermal infrared cameras have been installed on all NCOC icebreakers.
These cameras enable observers to watch the seals day and night, in blizzard or fog, at
the distance of hundreds of meters from the vessel, which allows bypassing the seals in
Comprehensive Caspian seal surveys programme
The successful implementation of the Programme for Comprehensive Caspian Seal
Surveys initiated by NCOC was continued in 2020 within the jurisdiction of the Republic
of Kazakhstan and the Russian Federation.
The leading participants of this programme are the Kazakh Agency of Applied Ecology
LLP (KAPE) and the A.N. Severtsov Institute for Ecology and Evolution under the Russian
Academy of Sciences (IEE RAS), Federal State Scientific Institution. At different stages,
research involves scientists from various scientific organizations: testing laboratory of
Chemical-Analysis Centre – Kazakh Agency of Applied Ecology LLP, Institute of Zoology
under the Ministry of Education and Science of the Republic of Kazakhstan, Scientific
and Production Centre of Microbiology and Virology LLP (NPC MiV), Kazakh Scientific
and Production Centre of Fishery (KazNPCRH), M.V. Lomonosov Moscow State University,
Moscow State Academy of Veterinary Medicine and Biotechnology of K.I. Scriabin Federal
State Budget Educational Institution of Higher Education (FGBOU VO MGAVMiB – MVA of
K.I. Scriabin), Federal Research Centre of Fundamental and Translational Medicine Federal
State Budget Scientific Institution (FGBNU FIC FTM), I.D. Papanin Institute for Biology
of Inland Waters under the Russian Academy of Sciences, Scientific and Production
2020 was a challenging year for the arrangement of offshore environmental surveys
because of quarantine sanctions. Yet, despite multiple quarantine restrictions the
Programme of Comprehensive Seal Surveys was successfully completed. In February 2020
a multi-spectral aerial survey of the pupping grounds on ice in the Kazakhstan sector of
the North Caspian Sea was carried out with use of Piper PA-34 fixed wing laboratory.
Regular counts of seals in the Caspian Sea with use of modern techniques and aerial
surveys and further processing of the acquired data shall be conducted at least for
three years (winter seasons) in order to identify the trends in changes of the Caspian
Like in 2019, a multi-spectral survey technique – a synchronised aerial survey in
the infrared and visible range of the pupping grounds of the Caspian seal – was
employed. The instrumental seal counts on ice allowed identifying 58,200 pups and
119,000 adult species. In 2020, according to the preliminary upper and lower limits
estimation of the total population based on the data of the multi-spectral aerial survey
of the seals ice rookeries, the abundance of the Caspian seals was 280,000 – 350,000
Since the distribution of the Caspian seal pupping grounds in the Kazakhstan and Russia
zones varies significantly in different years depending on the winter climate and ice
conditions, it is necessary to perform seals counts in the entire water basin of the North
Caspian Sea. Thus, the spring seal surveys in the moulting grounds were successfully
carried out as follows: in April – within the Russian water area on the Maly Zhemchuzhny
Island and the adjacent water basin, in May – within the Kazakhstan sector of the Caspian
Sea on the sand bars close to the North Caspian Sea Channel. During the seal surveys from
a sea vessel and with UAV use within the Russian sector of the North Caspian Sea over
1,000 seals were counted whereas an aerial survey over the Kazakhstan sector identified
more than 3,000 species.
In autumn, the Caspian seal surveys were continued within the Russian water basin in
the period from October 6 to 18 and in the area of the North Caspian Marine Channel
(Prorva) in the period from November 1 to 13. Morphometric surveys were completed
with acquisition of biological material for genetic, hormonal, serological, molecular and
virological, toxicological, and other studies. The seals count within the Russian sector
covered the area from Astrakhan Natural Reserve to the Maly Zhemchuzhny Island and
the Volga-Caspian Canal with biological sampling from six dead and two live species of
the Caspian seal. In addition to the morphometric and other studies, the tagging of 11
seal species with satellite sensors was performed in the Kazakhstan sector.
The modern ichthyofauna of the Caspian Sea, as compared to the open seas, does not
have a high species diversity and consists mainly of indigenous species. It comprises of 139
species and subspecies of fish and fishlike, five species of which are included in the Red
Book of the Republic of Kazakhstan.
Spring, summer and autumn fish surveys are performed regularly at NCOC
The process of ichthyofauna monitoring in 2020, like in the previous years, is characterized
by specific features and requirements that differentiate it from other types of
- Frequency of observations based on a fixed grid of monitoring points (stations);
- Unification, standardization of tools and methods of observation;
- Efficiency of review and interpretation of observed changes to identify ongoing
changes and ensure timely response.
Such requirements allow obtaining the comparable data on fish stock trends.
The 2020 monitoring surveys of the North Caspian ichthyofauna carried out by a licensed
contractor within the Company’s Contract Areas identified 70 species and subspecies of
fish, which is over 50% of the nominal list of fish inhabiting the Caspian Sea.
Sturgeon fish is the most valuable fish species in the Caspian Sea. These species are
currently endangered. In 2014 the Caspian states reached an agreement to ban commercial
fishing of sturgeon to restore its population.
In 2020 NCOC released 250,000 sturgeon fries to maintain the population of valuable
relict fish as part of the Fish Damage Compensation Environmental Programme. The
Company plans to continue the release of sturgeon fries into the Zhayik-Caspian basin in
the coming years.
Bird surveys in 2020
The North Caspian wetlands are the important grounds for over 280 bird species migrating
from Eurasia to Africa and India and nesting on the Caspian Sea coast and in the deltas of
inflowing rivers. The reed beds in this area are used by birds as shelters and for rest
the wintering, nesting and migrating periods.
NCOC realizes the importance of the region for preservation of global
thus, it performs annual and regular seasonal birds’ surveys since 2000:
- Two annual surveys during seasonal migrations (spring and autumn);
- Studies of nesting birds’ distribution in the coastal area during the reproduction
- Monitoring of wintering grounds for waterfowls and semiaquatic birds;
- Observations in the onshore and offshore areas and in the nesting period in summer.
Ornithofauna surveys cover the extensive area from the Volga delta in the west to the
Emba delta in the east, from Atyrau in the north to Aktau in the south.
The survey teams include NCOC ecologists, lead scientists and ornithology experts of
Kazakhstan involved by the licenced contractor for wildlife monitoring studies, and
inspectors from the Atyrau Oblast Department of Ecology and the Oblast Territorial
Forestry and Wildlife Inspectorate.
In 2020 the spring surveys were canceled due to the sanitary and epidemiological situation
and relevant restrictions. In summer, the surveys were carried out only onshore. 280,000
birds were recorded during the autumn survey on the northern coast westwards to the
Volga river and eastwards to the Emba estuary. The average density of birds in the
VolgaUral fluvial area has reached the maximum values for all these years, i.e. over 18,300
allotment (30-35 km2). Though the survey programme has been curtailed, the
birds’ distribution suggests a high number of mass species in the North Caspian Sea.
Ornithofauna surveys in the area adjacent to Atyrau airport
The world practice knows extremely high risks associated with birds’ strike to aircrafts,
particularly, to airplanes.
NCOC cares about the safety of the aircrafts using Atyrau airport, and thus, it decided
to take actions
aimed at assessing the ornithofauna risks and developing recommendations for their
ornithofauna observations in Atyrau airport adjacent areas.
Such activities were intended to address few tasks:
- Identify the conditions that could potentially cause a bird’s strike hazard, for
features of infrastructure, vegetation cover, land use rules and the nature of
activities in the pre-airport area;
- Identify the bird species’ composition, migration routes in the surveyed season,
behavior of birds depending on the season and the time of the day;
- Assess the risks of a strike of identified bird species to aircrafts;
- Develop actions and recommendations regarding deterrents for birds presenting a
- Develop recommendations on feasible modifications in the airport adjacent area in
reduce attractiveness of this area for birds and recommendations on mitigation of
risks by in-house aerodrome service units.
The field birds’ surveys were carried out by qualified bird experts with use of an UAV.
As a result, NCOC Aviation and Atyrau International Airport JSC were proposed specific
actions given the
ornithological situation in Atyrau and international practice regarding risks mitigation
and protection of
airplanes from collision with birds. In addition, effective technical and biological
means for protection of
airplanes from collision with birds were proposed.
The Caspian Sea level continues to drop in 2020 resulting in a further decrease of the
suitable for birds on the northern coast. Accordingly, number of birds in the interdelta
of the northern coast reduced due to their drainage and increased in pre-delta areas. It
was also noted that ongoing dredging operations along the fish channel in Ural delta have
created favourable conditions for the mass movement of fish in a relatively small area and
have attracted fish-eating birds from a large area, inducing a high concentration of birds
(up to 2,000 Dalmatian pelicans (Pelecanus crispus), over 500 white pelicans (Pelecanus
onocrotalus), and about 15,000 cormorants (Phalacrocorax carbo)).
6.4. Non-GHG air emissions
The primary air emission sources at NCOC facilities include flaring units, gas turbine units,
heating and hot-water boilers and diesel generators.
The flaring unit is a part of any oil and gas production facility and functions as a
“relief valve” of the plant to ensure safe operation of the facility. A small ignition flame
burns at all times, to ensure readiness to flaring. The height of the flaring unit ensures
maximum dispersion of combustion products in the air. Power is supplied to onshore
and offshore facilities by gas turbines units running on associated gas produced from
Kashagan field. The turbines are equipped with special burners designed to reduce
nitrogen oxide emissions. Boilers produce steam, heat water and provide heating for
buildings. Boilers run on fuel gas, however, use of diesel fuel is also possible. Diesel
generators are used only for stand-by power generation.
In 2020, the volume of non-GHG air emissions from all NCOC operations
was 23% of
permitted volumes, and totaled:
- 947 tonnes of volatile organic compounds (VOCs);
- 14,899 tonnes of oxides of sulfur (SOx);
- 3,818 tonnes of oxides of nitrogen (NOx excluding N2O, which is
reported under GHG air emissions).
SOx emissions at onshore and offshore facilities that make 94-76% of overall
air emissions consistently reduced from 2017 through 2020 owing to:
- Reduction in gas flaring volumes;
- Improvement of indicators of reliability and availability of technological
NOx emissions were higher versus 2019 due to increase in hydrocarbon production.
emissions were lower because of downtime of living quarters and support barges due to
limited operations at production facilities in the quarantine period.
Air monitoring is an important part of NCOC general programme for
monitoring. It includes the following several components:
- Under-plume monitoring;
- Monitoring at emission sources;
- Air quality monitoring stations (AQMS).
Air quality monitoring stations
Supported financially and technically by NCOC, 20 automatic stations for continuous
monitoring of the air quality are installed in Atyrau City and Atyrau Oblast. 4 stations are
located along the perimeter of the 7-km sanitary protection zone of Bolashak OPF; 7 more
stations are installed in nearby and remote from the OPF settlements including Dossor and
Makat; and 9 stations are located in Atyrau city.
The AQMS operate on a 24/7 basis and continuously measure the concentrations of 5
components (hydrogen sulphide, sulphur dioxide, nitrogen dioxide, nitrogen oxide and
carbonic oxide), which are the main air pollutants, as well as meteorological parameters
determining the conditions of contaminant dispersion in the air (wind speed and direction,
temperature, barometric pressure and relative humidity).
The data from NCOC air quality monitoring stations
is available for Atyrau community
In 2020 ʺKazhydrometʺ RSE developed and rolled out the mobile application
an interactive map of environmental data which allows online monitoring of current air
parameters in the entire territory of Kazakhstan by any person
NCOC took part in the project under the Roadmap for Comprehensive Solving
Problems in Atyrau Oblast dated 21.09.2020.
In the course of the project implementation, the Quadruple Agreement
the information about the air quality was signed between NCOC, Atyrau Oblast Branch of
ʺKazhydrometʺ RSE, Atyrau Oblast Department of Ecology and Atyrau Oblast Department of
Natural Resources and Environmental Management.
The project was successfully completed by December 2020. The air quality
data from 8 stations of the Company located in the main microdistricts
of Atyrau City (Zhilgorodok, Avangard, Vostok and others) is available
on ʺKazhydrometʺ RSE interactive map (https://maps.hydromet.kz/)
and in the AirKz application that can be installed via App Store or
Comprehensive air quality studies
within Atyrau City and in Eskene West, Bolashak OPF location area
In 2019 NCOC launched the Project “Comprehensive Air Quality Studies within Atyrau
City and in Eskene West, Bolashak OPF location”. This Project was initiated to respond
residents’ concerns about the deterioration of air quality caused by increase of
emissions in the region and their negative impact on the health of the people.
The Project is intended to systematize, analyze and summarize the historical monitoring
data acquired by both NCOC and Atyrau Oblast Branch of Kazhydromet RSE, as well as to
implement the extended air monitoring for pollutants which are the most significant for
control of the morbidity rate of the population.
This work will allow assessing the trend of changes in the quality of atmospheric air and
time and space of pollutants distribution in order to identify the negative effects of
and anthropogenic factors.
The Atmospheric Air Monitoring Programme was developed under the Project and
presented to the public for discussion at a Round Table on November 6, 2020.
According to the Programme, the monitoring of atmospheric air quality in the city is
performed at 16 conditional stations, evenly distributed across the territory of the
centre (grid size 3 km x 3 km), including two baseline stations (in the south-eastern
north-western parts of the city).
Air studies on the border of the sanitary protection zone of Bolashak OPF and nearby
the settlements (Karabatan, Taskesken, Eskene stations) are carried out at 6 conditional
observation stations. Their locations are determined based on the results of a
analysis of the historical data from the Company’s air quality monitoring stations.
In accordance with the recommendations given in the regulatory and technical
documentation, measuring and air sampling activities are carried out under the full
programme at 01:00, 07:00, 13:00, 19:00.
Due to the harder quarantine measures introduced because of COVID-19 spread, the
monitoring activities in certain periods were carried out based on a shortened
programme, only during daylight hours (07:00; 13:00; 19:00).
The studies are performed for 32 pollutants of different classes:
- Saturated, aromatic, polyaromatic hydrocarbons;
- Heavy metals;
- Solid substances, etc.
The list of parameters to be included in the Programme was
determined by the following
- Substances released during NCOC operations;
- Substances of a high hazard class (toxicity, carcinogenicity);
- Substances that have a sharp unpleasant odour;
- Substances that make the maximum contribution to environmental pollution based
on the Bolashak OPF emission reports
This approach enables to identify substances that might be or are critical to the region
are subject to control.
The accredited laboratories having experience in atmospheric air monitoring and
necessary equipment are involved into the studies. These include the Republican Research
Centre for Atmospheric Air Protection, the Centre for Physico-Chemical Methods of
Research and Analysis under Al - Farabi Kazakh National University, PC Gidromet Ltd and
The project execution employs modern research methods certified in the Republic of
and the equipment to determine the minimum concentrations of pollutants in the
air (for example, various types of chromatography methods). Also, the project employs
latest technologies widely used in the international practice, but with a limited
the Republic of Kazakhstan. They allow continuous 24-hour sampling simultaneously at
stations for subsequent assessment of the qualitative and quantitative composition of
(Thermal Desorption Gas Chromatography-Mass Spectrometry).
It is planned to complete the comprehensive studies in December 2021, following a full
analysis and consolidation of the acquired data. The research data will be available on
The remote data transfer project has been implemented for the purpose of centralized data
collection from the stations. It allows the transfer of measurements data on a 24/7 basis
from every AQMS to the central computer in NCOC office, where such data is analyzed and
stored. Simultaneously, the specialists of Atyrau Branch “Kazhydromet” and Atyrau Oblast
Department for Natural Resources and Nature Use Regulation are provided with a remote
access to the data received from the Company’s stations and an opportunity for online
monitoring of the air quality.
Since 2016, the Company has been carrying out the modernization and upgrade of the
stations including enhancement of the data transfer system to reduce the data deference
time, resulting in the interval reduction to 1 hour; the gas analyzers installed in the OPF
area have been replaced with new series models. The phased upgrade of the measuring
tools at all stations will continue in 2021–2022. In addition, the issue of relocating the
Oil station No.104 installed in Atyrau southern industrial zone to a residential area of the
city to control the pollutant impact on the population is under joint review with the state
Hydrogen sulfide (H2S) is another non-GHG air emission. It is a flammable and
toxic substance with a strong and unpleasant odor. It can be generated anywhere with
decomposition of sulfur-containing organic materials in absence of oxygen; thus, it is
emitted naturally in marsh gases and volcanoes (sometimes in large quantities), oil and
associated gas in some oil and gas fields.
Given the sour nature of Kashagan field, hydrogen sulphide is present at every stage of oil
and gas production, transportation and processing and, accordingly, at all Company’s units
associated with these processes.
NCOC specialists who work at the operational facilities, particularly, in immediate proximity
to wellheads, flash gas compressors and other equipment attend a special training and use
personal detectors and breathing apparatus. Depending on the facility hazard level and
activities, they use respirators and escape self-contained breathing apparatus or
breathing apparatus. With farther move from these locations, the risks and potential
H2S concentrations reduce rapidly.
NCOC can state with confidence that Bolashak OPF is safe for the community. The primary
guarantor of safety is the 7-km sanitary protection zone (SPZ) around Bolashak OPF,
sufficient to protect the residents of the nearby settlements from long-term air emissions
impacts on their health and providing a high margin of safety even in case of non-routine
events. Such confidence is driven by a careful design, the outcomes of multi-year studies
and computer modelling, the conclusions of the state expert reviews and regulators’
approvals, and finally, by recent operating practice that confirms the appropriateness of
models. As in the previous years, the results of the continuous monitoring in 2020 indicate
that the short-term H2S peaks (from 1 to 20 minutes in duration) are still far
more likely in
Atyrau than close to Bolashak OPF.
Nevertheless, NCOC monitors the exceedance of air quality rates recorded at the AQMS in
Es-kene West to identify the possible causes, including potential internal or external
the wind direction at the time of the exceedance. It is difficult to confirm the impact of
any po-tential pollution sources at NCOC facilities as emissions from sources at the
are within the regulatory limits for emissions and discharges and, therefore, are not the
cause of the exceedance. Additional studies are required to establish and confirm the
The completion of such studies is planned in 2021 (see Case Study Section Comprehensive

operational facilities under the Bolashak OPF Sanitary Protection Zone Size
Project. As of today, the greened area is 14.2 hectares. However, due to unfavorable
and climatic conditions in the SPZ, the Company considers a possibility of tree-planting
another territory based on the updated SPZ project. As part of these upcoming updates in
SPZ project, the Company plans to contribute in tree-planting in the areas allocated by
Oblast Akimat within Atyrau City and Atyrau Oblast territory. In this regard, the
discussing now the Memorandum developed by Atyrau Oblast Akimat thereunder the parties
consider the continuation of tree-planting within the city and oblast area.
Moreover, pursuant to the Memorandum regarding implementation of the pilot
tree-planting along Atyrau – Karabatan – Dossor highway, the Company planted trees in

The total volume of waste generated by the Company in 2020 was 4,839 tonnes, including
2,209 tonnes of amber-level waste and 2,630 tonnes of green-level waste
The waste volume generated in 2020 dropped significantly versus 2019. The main source of
waste generation in 2019 was preventive maintenance/turnaround conducted in the first half
year. Meanwhile, in 2020 many activities at the Company’s facilities were suspended due to
pandemic outbreak, declaration of the state of emergency in the Republic of Kazakhstan.
NCOC Waste Management System is aimed at reduction or generation of zero waste at the source
during the operational process through a proper planning of the Company’s operations.
NCOC Waste Management System presents a full cycle from waste generation to final waste
Waste segregation (sorting) is one of the critical phases of the process cycle. It is
prohibited to mix
hazardous and non-hazardous wastes; therefore, they are collected separately at the
into dedicated containers and insulated tanks. For this purpose, additional special (Euro)
domestic waste and cages for plastic wastes have been installed.
According to the requirements of the RoK National Standards, all facilities in the Company
have in place
a system for separate collection of waste oil based on its types (engine oil waste,
industrial oil waste and
oil transmix waste), batteries, mercury wastes and vehicle tyres.
The awareness events take place at the facilities on a monthly basis for better understanding
waste collection by the personnel.
The decrease of the waste volumes and its toxicity is achieved at the
Company’s facilities through the
mechanical or thermal treatment:
- Food and medical wastes refer to the hazardous waste. To reduce their hazardous
ensure compliance with the sanitary requirements, TeamTec double chamber Incinerators
installed at the offshore facilities (Floatels);
- To reduce the wastes generated at the Company’s onshore facilities in Atyrau Oblast, a
is used to compact the paper and cardboard wastes.
All wastes generated at the Company’s facilities are handed over to a contractor for further
and disposal under a Waste Handover Statement. The contractor performs pre-treatment of the
through removal of mechanical additives and water for its further transfer to processing
Following the additional segregation and pre-treatment at the contractor’s facilities, the
metal scrap, paper and cardboard waste, scrap tyres, batteries, waste oils are converted
into the recyclable
materials and transferred to specialized organizations for further processing.
Timber wastes are provided to the local community on a free of charge basis.
NCOC performs a phased replacement of mercury-containing lamps with
LED lamps at its facilities. In 2020
1,518 fluorescent lamps were replaced with LED lamps at the facilities in Atyrau Oblast. The
effect from replacement of fluorescent lamps with LED lamps is driven by the following
- Longer service cycle of LED lamps as compared to fluorescent bulbs results in reduction
- LED lamps are mercury free and, thus, they are safe both in operation and disposal as
- LED lamps consume less power.
In pursuing its waste management strategy, the Company is committed to comply with the
of the national and international standards.
