What are some innovative technologies for sustainable airport operations?

1 Solar power

One of the most common and effective ways to reduce airport emissions and energy costs is to install solar panels on the roofs, parking lots, or nearby lands of the airport. Solar power can provide clean and renewable energy for the airport's lighting, heating, cooling, and electric vehicles. Some airports that have already implemented solar power include Cochin International Airport in India, which is the world's first fully solar-powered airport, and Denver International Airport in the US, which has a 56-acre solar farm.

2 Biometric screening

Another technology that can improve airport sustainability and efficiency is biometric screening, which uses facial recognition, iris scanning, or fingerprinting to identify and verify passengers. Biometric screening can speed up the check-in, security, and boarding processes, reducing queues, waiting times, and paper consumption. It can also enhance security and safety by preventing identity fraud and tracking passengers' movements. Some airports that have adopted biometric screening include Changi Airport in Singapore, which has a biometric system called FAST (Fast and Seamless Travel), and Dubai International Airport in the UAE, which has a biometric tunnel that scans passengers as they walk through.

3 Waste management

A third technology that can help airports achieve sustainability goals is waste management, which involves reducing, reusing, recycling, and recovering waste materials. Waste management can lower the environmental impact of airport operations by diverting waste from landfills, saving resources, and generating revenue. Some of the innovative waste management technologies that airports can use include smart bins that sort and compress waste, waste-to-energy plants that convert waste into electricity or heat, and circular economy models that reuse waste as raw materials for other products. Some airports that have implemented waste management technologies include Schiphol Airport in the Netherlands, which has a waste-to-energy plant that powers 60,000 households, and Gatwick Airport in the UK, which has a circular economy project that turns coffee grounds into biofuel.

4 Artificial intelligence

A fourth technology that can enhance airport sustainability and performance is artificial intelligence (AI), which refers to the use of machines or software to perform tasks that normally require human intelligence. AI can help airports optimize their operations, reduce costs, and improve customer service. Some of the applications of AI in airports include predictive analytics that forecast passenger demand, traffic flow, and weather conditions, chatbots that provide information and assistance to passengers, and autonomous vehicles that transport luggage, cargo, or people. Some airports that have leveraged AI in their operations include Heathrow Airport in the UK, which uses AI to monitor and manage its airspace, and Helsinki Airport in Finland, which uses AI to detect and prevent wildlife hazards.

5 Green buildings

A fifth technology that can contribute to airport sustainability and comfort is green building, which refers to the design, construction, and operation of buildings that minimize their environmental impact and maximize their human well-being. Green buildings can help airports save energy, water, and materials, reduce emissions and waste, and create a healthy and pleasant environment for passengers and staff. Some of the features of green buildings include natural ventilation, daylighting, green roofs, rainwater harvesting, and smart sensors. Some airports that have achieved green building certifications include San Francisco International Airport in the US, which has a LEED Gold terminal, and Vancouver International Airport in Canada, which has a Salmon-Safe certification.
