Airport waste impacts the environment similarly to other forms of waste. Recyclable materials and retail waste, when sent to landfills, occupy precious space and can release harmful chemicals, impacting the surrounding environment. Conversely, food waste from airport eateries can be incinerated to produce renewable energy, though this process emits greenhouse gases.

Waste from aircraft poses a greater environmental threat. Leaked or improperly disposed of chemicals, oils, and toxic substances from aircraft can significantly contribute to pollution in the air, soil, and water.
