  • Waste Minimization & Recycling Management

 
Integrated Waste Management (IWM) at QAIA - particularly Solid Waste Management (SWM) - has improved significantly over the past five years as a result of the continuous enhancement of SWM infrastructure. Controls were placed to oversee waste carriers and producers as per the IWM Plan and the waste sorting and recycling project spanning all QAIA buildings and facilities. Moreover, new categories were added to the recycling list, such as used tires, oil and batteries.
 
IWM objectives are summarized as per the below:

  1. Upgrading existing solid waste sorting and segregation technologies and equipment.
  2. Applying the 4Rs concept (Reduce, Reuse, Recycle, Recover).
  3. Distributing recycling bins at offices for the segregation of waste at the source.
  4. Involving all employees - including supervisors of cleaning companies - in awareness sessions regarding hazardous waste removal and waste recycling procedures.
  5. Increasing the frequency of training and awareness sessions, whilst ensuring the attendance of supervisors and managers.
  6. Minimizing the mixing of general waste with hazardous waste (i.e. sweeper operations with vehicle maintenance).

 
The overall waste quantity generated from the operations of the QAIA New Terminal and Airport International Group facilities was reduced by 4% in 2019 compared with 2018. This decline was also reflected in the waste quantity per passenger, which dropped by 3% to reach 0.39kg/PAX in 2019, as opposed to 0.4kg/PAX in 2018.
 
During 2019, greater focus was placed on enhancing cardboard and paper segregation and involving QAIA concessionaires - such as the Duty-Free and airline partners. This joint collaboration resulted in an increase in cardboard and paper segregation of around 16% and 200%, respectively, throughout the year. Moving forward, Airport International Group is looking to include plastic waste in its waste segregation program.
 
As for hazardous waste handling and management, empty oil and paint cans comprise 53% of Airport International Group’s hazardous waste, which is collected and packaged as per national requirements and transported to a licensed treatment center.

  • Energy Management

 

During 2019, annual energy consumption of the entire airport site reached 77,679,431 kWh and associated CO2 emissions amounted to 43,813 tCO2.
 
In parallel, annual energy consumption of third parties located at the airport premises (tenants and concessionaires), which Airport International Group supplies with electricity, reached 30,586,224 kWh - nearly 42% of the total energy consumed. Meanwhile, the energy directly consumed by Airport International Group in 2019 settled at 47,093,206 kWh and associated CO2 emissions were 25,828 tCO2 for the same period.
 
In 2015, Airport International Group conducted an Energy Audit to determine opportunities to reduce its energy consumption. Accordingly, several cost-effective, energy-efficient improvements were identified - requiring a variety of no-cost, low-cost, medium-cost and high-cost measures. Over the past four years, most of the recommendations concluded in the 2015 Energy Audit were implemented, namely:
 

  • Optimizing schedules of heating, ventilation, and air conditioning (HVAC) systems serving intermittently-occupied buildings, such as the Operations Building and corporate offices.
  • Lowering heating set points.  
  • Installing lighting controls in selected applications to reduce light levels when natural light is sufficient or to switch off or dim lights when areas are unoccupied.
  • Installing variable speed drives (VSD) and controls in selected applications, including air handling units (AHU), fan motors and pumps.
  • Replacing lighting with LED equivalents in selected applications.
  • Decentralizing the Central Utilities Plant, which is in need of refurbishment and whose load was drastically reduced since the QAIA Old Terminal was demolished.

 
The quantified energy efficiency measures outlined above reduced both energy consumption and costs. The capital required to achieve these savings was over JOD 1.9 million, with a simple payback period of 1.74 years across all measures. Based on Airport International Group’s energy saving measures between 2014 and 2017, QAIA won the Silver award in the ACI Asia-Pacific Green Airports Recognition 2017, which was held under the theme ‘Energy Management’ - coming in third place in the category of airports serving less than 25 million passengers per year.
 
In 2020, Airport International Group conducted a second Energy Audit to identify additional opportunities to introduce energy saving measures.
 
Accordingly, 21 potential energy efficiency projects were specified - including, but not limited to:
 

  • Adjusting AC temperature set points in the server rooms to a higher level consistent with IT cooling requirements.
  • Installing controls to switch off lighting when daylight is sufficient or rooms are unoccupied.
  • Replacing lighting with LED equivalents in selected applications (building on the considerable work done in this area over the past four years).
  • Deploying PC power management software to shut down PCs and other equipment when not in use.
  • Installing VSD and occupancy-linked (CO2-sensing) controls in air handling units serving the Terminal Building to reduce airflow during less busy periods.  
  • Changing the way water is stored and pumped for use throughout the terminal.
  • Decentralizing the Central Utilities Plant (a project previously identified but not yet been completed).

 
The above energy efficiency measures can reduce Airport International Group’s energy consumption by approximately 18.7% and associated CO2 emissions by approximately 18.6%.
 

  • Water & Wastewater Management 

 
Water management at QAIA may prove more complex after considering the impact of climate change on available water resources. Consequently, prudent management plans must be developed to meet future water demands.
 
Within this context, systematic actions at QAIA are required to manage both water demand and water supply. On the demand side, the concept of water conservation must be promoted and implemented via the controlled and efficient use and reuse of water, among other measures. For instance, demand management focuses on reducing water consumption by utilizing related smart technologies, such as water-saving devices and air-cooling systems that do not use water cooling towers. The main objective of demand management is to minimize the need for water supply and wastewater treatment, both of which are associated with high costs and may be environmentally detrimental. On the other hand, supply management is related to the search for alternative water resources, including rainwater harvesting that may be used for non-potable activities like firefighting, air-cooling systems, fire training and road sweepers.
 
Accordingly, in 2019, Airport International Group collaborated with the University of Jordan to conduct an assessment study on current water management schemes to identify best water management alternatives that would ensure smooth operations at QAIA without creating a negative impact, such as groundwater depletion and pollution.
 
The assessment study shed light on the following areas for improvement:
-       Developing a water management strategy and policy.
-       Reducing water supply from external suppliers. 
-       Devising a water saving plan to decrease consumption.
 
As a result, in Q4 2019, Airport International Group began outlining the framework for a comprehensive water management strategy that is currently under preparation. Meanwhile, other actions have been implemented onsite:
-          Resizing and replacing water meters.
-          Fixing water leakages in the firefighting water supply network.
-          Replacing nearly 4,000 meters of the old network with polyethylene pipelines.
-          Switching from potable water to reclaimed water for the irrigation of certain areas.
 
The abovementioned actions actively reduced the water consumption of Airport International Group activities by approximately 15% and overall airport water consumption - including stakeholder activities - by around 9%.
 
This was achieved by focusing on water consumption reduction, water quality improvement and a robust water management strategy to ensure the long-term sustainability of water resources. Around 75% of treated wastewater is currently being used in the irrigation system - a percentage that Airport International Group is looking to bolster as a replacement for potable water. The quality of reclaimed wastewater is monitored frequently in coordination with the accreditation laboratory.
