In honor of Plastic-Free July, we’re spotlighting the overlooked yet high-impact role of airports in the fight against plastic waste.
While the aviation industry is often scrutinized for its carbon footprint, a quieter environmental crisis is unfolding on the ground — in terminals, lounges, and food courts worldwide. Airports, operating like mini-cities, generate tons of single-use plastic every day: water bottles, coffee cups, cutlery, food packaging, straws, and security bags. In the UK alone, security checkpoints discard over 5,000 tonnes of plastic bottles each year.
Around the world, forward-thinking airports are proving that real change is possible when infrastructure, policy, and collaboration come together:
San Francisco International Airport (SFO) led the charge by banning the sale of plastic water bottles in 2019 and later expanded the ban to all plastic beverage containers. It installed over 100 hydration stations to encourage refills.
London Heathrow introduced over 100 free refill points, partnered with vendors to eliminate plastic straws and stirrers, and began phasing out single-use security bags with the help of new CT scanning tech.
Dubai International (DXB) pledged to eliminate single-use plastics from all customer-facing operations, with 95% of concessionaires complying.
Singapore’s Changi Airport deployed smart recycling bins with gamification features to boost engagement and expanded terminal-wide recycling access.
Adelaide Airport piloted a plastic-free food court by working closely with vendors ahead of incoming regulations.
Gatwick Airport recycles all plastic bottles on-site and has achieved zero waste to landfill.
These success stories are promising but they represent only part of a bigger picture.
Despite progress, several challenges continue to hinder large-scale plastic reduction in airports:
Health and safety regulations are a major factor: for food service and security reasons, many items have historically been individually wrapped or single-use to maintain hygiene. (Indeed, during the COVID-19 pandemic, some sustainability gains reversed as airports reverted to disposable packaging for sanitation).
Aviation security rules also played a major role, the long-standing requirement to pack liquids in clear plastic bags contributed to plastic waste. though new scanner technology is mitigating this.
Cost and supply chain limitations: eco-friendly alternatives (like bioplastics or compostable ware) are not always available at scale, and they tend to be more expensive. In a recent industry survey, 83% of aviation stakeholders cited higher costs as the biggest deterrent to switching away from conventional plastics.
Inconsistent regulations across countries make it harder for global vendors to align procurement and compliance efforts.
Passenger behavior also plays a role: convenience often wins, and sustainable habits like carrying reusable bottles are not yet mainstream.
Despite the complexity and regulatory constraints of airport environments, a growing number of hubs are proving that single-use plastic can be dramatically reduced through a combination of strategic policy, stakeholder coordination, and targeted innovation. As seen in the examples above, success stories span the globe — from hydration stations and compostable packaging to AI-driven sorting bins — showing that practical, scalable solutions do exist and are already delivering results.
The key takeaway is clear: when airports invest in infrastructure, align with vendors, and embed sustainability into the traveler experience, meaningful change follows — with reduced environmental impact, operational savings, and enhanced brand perception. As the pressure to decarbonize grows, airports that treat plastic reduction not just as a compliance issue, but as an opportunity for smart, value-generating innovation will be better positioned to lead the future of sustainable aviation.
