Key areas

Waste Management

The waste management policy is highly important and is aligned with the objectives focused on by the VINCI Airports network.

Our policy focuses on:

  • Reducing generated waste
  • Increasing the amount of recycled waste through collection, segregation and delivery to authorized waste management operators
  • Active promotion of circular economy
  • Monitoring hazardous waste handling from the moment of generation to final disposal by authorized operators
  • Reaching the goal of “Zero waste to landfill” by 2030.

Waste-water management and water quality

One of the key goals of Belgrade Airport is sustainable water management with the ambitious goal of halving water consumption per passenger at the airport complex by 2030.

Managing the drinking water quality

Airport’s water supply system is connected to the network of the facility located on the left bank of the Sava River classified as the first "outlet zone". Belgrade Airport conducts regular inspections of drinking water quality pursuant the Environmental Monitoring Plan and regulations governing this area.

Waste-water management

One of key areas currently in focus is to adequately manage waste water (atmospheric waste-water, sanitary waste water and faecal sludge and aircraft waste water). In order to reduce the risk of groundwater and surface water pollution, several measures for the purification of waste water (atmospheric and sanitary-faecal), as well as the use of rainwater, were implemented within the Airport reconstruction project.

The collection and treatment of waste water by Belgrade Airport has been improved by the implementation of the following measures:

  • By operating the plant for the processing of sanitary and faecal waste water(WWTP) located at the airport complex.
  • Reuse of purified waste water from the sanitary-faecal waste water treatment plant, for irrigation of green areas
  • Installation of grease and oil separators for atmospheric waste water generated at manoeuvring areas
  • Collecting rainwater from the roof on the new sections of the terminal and reuse of rainwater in toilets

Groundwater management

Quality of groundwater is monitored at 8 locations within the airport complex where potential pollutants may enter into groundwater system.

Points where measurements are conducted - monitoring wells - are located near locations on the airport complex that are recognized as potential polluters (de-icing platform, airport fuel storage, transformer station, NIS fuel storage, closed waste landfill).

Soil management

Quality of soil is analysed in order to identify sensitive and overloaded areas, to establish a database on the degree and characteristics of contamination, as well as the types of pollutants present. Soil contamination can be local (point source) or diffuse- through atmospheric and underground water. Improper disposal and accidental release of toxic and dangerous substances, mainly due to work related activities, leads to soil pollution. Sampling is currently being carried out at the airport complex on the location of the transfer station.

Ambient air quality management and air pollutant emissions

Air pollution is the presence of chemical, physical or biological agents in the air (either atmospheric or indoor) which change the natural characteristics of the air.

The most common activities that lead to emissions of pollutants into the air are: combustion of fossil fuels in the process of obtaining electricity, products of fuel combustion in motor vehicles, various technological processes, disposal of garbage in landfills or burning of agricultural crops, aircraft during landing and take-off, fumes from fuel storage and fuel handling, etc.

Monitoring of ambient air quality is conducted twice a year at 4 locations on the wider airport complex.

Biodiversity management

In the previous period and pursuant to VINCI Airports Environmental Policy, Belgrade Airport undertook the following initiatives to preserve and improve biodiversity:

  • In the course of 2022 and 2023, honey plants (lavender) were planted at several locations, thus greening the area and and assisting in preservation of bees
  • beehives were also placed within airport complex
  • a protective net was installed as to prevent birds entering into areas where air operations are in progress
  • treating protected species caught within the airport complex pursuant to good practice and in cooperation with competent institutions
  • greening the areas around the airport complex in 2023

Ecological facilities

Since 2020, significant funds have been invested in infrastructural projects focused on modernizing, expanding and reconstructing the airport, strongly emphasising the projects having a direct impact on improving and protecting the environment.

New facilities have been constructed: a modern heating plant, a solar power plant, LED lighting was installed throughout the airport complex, two plants for collecting and segregation of generated waste, as well as the plant for the treatment of sanitary/sewage waste water.

New heating plant

A new heating plant using 44 MW natural gas replaced the old plant which was fuel oil based. The advantage of the new heating plant is the reduction of environmental impact by using less pollutant energy sources and switching from heavy fuels to natural gas.

The new plant is equipped with a trigeneration system that produces electricity and, in addition, thermal energy used for heating in the winter and for cooling in summer months, jointly with the absorption chillers. This system increases heating efficiency by approximately 25% and reduces carbon footprint by 25%. This power plant enables Belgrade Airport meet more than 70% of its electricity needs from its own sources.

The new power plant, which became operational at the end of 2021, in addition to reducing environmental impact also provides considerable savings due to the use of available natural resources.

Solar plant

Photovoltaic solar system with 2984 modules having the installed power of 1 MWp is located on an area of 15,900 m2.

The solar power plant supplies airport complex with electricity obtained from renewable sources and produces approximately 1,130,000 kWh of green electricity per year, which is comparable to the annual consumption of nearly 430 households. The expected reduction of greenhouse gas emissions is about 10%.

The solar plant is located next to the Tesla car park and was put into operation in 2022.

LED lighting

In the course of 2022 and 2023 measures have been initiated as to improve environmental protection as per the circular economy principles. Current lighting system has been replaced by LED lamps - more than 98% of the lighting within the old terminal and entire system of the new terminal and at new car parks.

140 poles with LED lighting have been installed along the service road in front of the terminal and in the car parks, which use solar energy therefore do not require conventional electrical power from the network. As per the initial projections, solar lighting will reduce the emission of harmful gases by 67,600 kg per year.

Transfer station for waste collection and segregation

The transfer station for the collection and sorting of generated waste and the temporary storage of recyclable waste until it is handed over to authorized operators for recycling, is located in the public zone of the airport /landside, while other such facility is located within the security-restrictive zone/airside.

Transfer station for waste segregation - in the public zone

The waste sorting facility - transfer station located within the landside is furnished with modern equipment for segregations and temporary storage of recyclable waste and was commissioned on September 22, 2022, on the VINCI Environment Day.

The facility is intended for manual sorting of solid, communal and waste generated outside the security restricted zone, according to the type of waste, and for temporary storage in designated containers for recyclable waste until it is handed over to an authorized recycling operator. The non-recyclable residue is handed over for final disposal at the landfill.

Currently, 9 streams of recyclable waste are separated in the waste sorting transfer station: cardboard, PET packaging, cans, glass, foil, tetra pak packaging, paper, hard plastic and metal cans.

Records are kept on the amount of mixed municipal waste entering the facility, the amount of processed and sorted recyclable waste and the of the remaining non-recyclable municipal waste.

Efficiency of municipal waste segregation, i.e. the share of separated waste for recycling in relation to total municipal waste (recycling percentage) per month during 2023 is shown in the graphic below.

Recycling waste

Solid waste plant located within the security-restricted zone

The second facility - transfer station was built in the security-restricted zone/ airside and is used for the collection and temporary storage of catering waste from international transport (animal by-products category 1 from aircraft) in a cooling chamber, until handed over for further transport and further handling by an authorized operator registered for performance of such activities under the Veterinary Administration.

Solid waste plant

Waste-water treatment facility

The new plant for the treatment of sanitary waste water from the airport complex was constructed in 2023 and final adjustments are currently in progress.

Its designed capacity is 750m3 per day and will treat waste-water of various origins, such as:

  • Waste -water from the terminal building
  • Waste-water generated by commercial aircraft operations (so-called "blue water")

The project stipulates that portion of the processed water will be additionally treated and used to irrigate green areas within the airport complex, in order to reduce water consumption, all in accordance with the VINCI Airports Policy regarding the rationalization and reduction of water consumption at airports.

Collecting rainwater from the roof of the newly constructed section of the terminal

The initiative to collect and use rainwater represents a significant step forward in the implementation of activities as to achieve the universal goal of halving water consumption by 2030.

In 2022, a rainwater collection system was put into operation as part of the newly constructed Pier C, which allows the collected technical water to be used in the toilets after it has been treated, in the newly constructed section of pier C from C7 to C14.

Filtration and disinfection is carried out thus enabling use of rainwater for technical purposes,

This innovative measure of improvement in water management will significantly contribute to reducing the consumption of sanitary water from the city's water supply network and represents a model of sustainable business based on principles of circular economy .

Local community

Aircraft noise management

Belgrade Airport is committed to cooperation with the local community and recognizes that living near the airport or the flight path can cause the sound and visual effects produced by the aircraft, i.e. side effects and events related to aircraft operations, to be more evident. It is our intention to involve each interested party, through transparent communication and cooperation, thus becoming our partner in solving possible issues related to noise management.

As per the applicable Air transport Law, when an airport handles more than 50,000 take-offs and landings per year, it is obliged to establish continuous aircraft noise monitoring.

Belgrade Airport has established a system for 24/7 monitoring noise and flight directions , in order to enable monitoring and management of environmental impacts, in accordance with the international standard ISO 20906.

The noise monitoring system consists of several noise monitoring stations continuously monitoring noise levels (microphones) and one portable station. The noise monitoring stations are connected via ADSL to the server platform. This server also receives operational data, including radar data on the type of aircraft movement and relevant aircraft operator data.

There are currently 5 fixed units and 1 portable unit installed, which are located as to cover the area considered to be at risk from aircraft noise.

The aircraft noise management is an issue of importance to multiple internal and external organizations. First of all, the issue of noise management is important for the Republic of Serbia, the competent Ministry of Environmental Protection, the Environmental Protection Agency, all in accordance with the Law on Environmental Noise Protection (Official Gazette of RS, No. 96/2021 ("Official Gazette of RS", No. 96/2021 ).

Directive 2020/49/EC on the assessment and management of environmental noise has been implemented to a larger extent in the Law on Protection from Noise in the Environment ("Official Gazette of the RS" No. 96/21), and it requires drafting a Strategic Noise Map for the main airport, main roads and railways on the territory of the RS, as well as stipulating that legal entities being the owners and concessionaires of the above infrastructure shall be responsible for creation of such document jointly with other entities involved in the environmental protection. Strategic noise maps should be created using the assessment method recommended in Annex II of the END Directive as specified in EU Directive 2015/996.

Strategic noise maps shall be reviewed and, if necessary, revised every five years as of their drafting/creation date and shall represent the basis for the development of relevant action plans as well as a method of informing the public about the level of environmental noise and harmful effects thereof.

Web track

WebTrak - Aircraft noise monitoring application

The online flight tracking application WebTrak enables automatic submission of suggestions/requests/complaints in the event that our fellow citizens, users or partners consider that the level of aircraft noise is above normal values, which may occur if the aircraft deviates from its flight path during arrival or departure from the airport .

In the course of 2022, the "WebTrak" application became publicly available for all interested parties, and in this way a transparent, free and accessible complaint mechanism was implemented by which citizens' complaints will be recorded and resolved.

VINCI Airports continues its decarbonization actions in Europe and worldwide and reaffirms its objective of achieving net zero emissions throughout its network by 2050

Decarbonisation actions

BELGRADE AIRPORT continues its decarbonization actions and reaffirms its objective of achieving net zero emissions

On the occasion of the second ACI EUROPE summit on the sustainability of aviation and as part of the airport sector's joint commitment currently subscribed to by 235 European airports, BELGRADE AIRPORT, member of VINCI Airports network is reaffirming its objective of achieving net zero emissions throughout its network by 2050.

As the first airport operator to commit to an international environmental strategy in 2015, VINCI Airports is multiplying its actions to be exemplary in reducing its own CO2 emissions and to contribute to reducing air transport emissions, which represented 2.8% of global emissions in 2019. VINCI Airports is thus deploying concrete and immediate solutions that limit the impact of airports, which have already reduced the network's carbon footprint by 22% between 2018 and 2020.

To reduce energy consumption, several levers are used: energy audits and deployment of energy management systems, replacement of traditional lighting with LEDs, renewal of heating/air conditioning equipment with more efficient appliances, or optimization of temperature settings or lighting.

In the same time, VINCI Airports is working to decarbonize the energy it consumes by, for example, producing its own solar electricity, with 17MWp already installed on its network, including 8MWp of green energy added in 2020 despite the crisis, or by renewing its technical vehicle fleets to switch to electric power.

VINCI Airports is also the first international airport group to have committed 100% of its platforms to the voluntary Airport Carbon Accreditation (ACA) program of the Airports Council International, the only international greenhouse gas emission reduction program specific to airports. 24 airports have already reached level 2, which attests to an effective and sustainable reduction in CO2 emissions. Lyon-Saint Exupéry and London Gatwick airports have already received 3+ accreditation for carbon neutrality, and Guanacaste airport in Costa Rica has been recognized as carbon neutral by the NGO EARTH University. In Brazil, Salvador Bahia Airport was named the country's "most sustainable airport" in 2019 by the National Civil Aviation Agency (ANAC).

The next objective is to achieve carbon neutrality for all airports by 2030, followed by "zero net emissions" by continuing decarbonization actions and absorbing residual emissions through forest carbon sinks.
