Daily activity at the airport generates around 10,000 tonnes of waste a year, which has to be managed to conserve natural resources, reduce the pollution caused by its accumulation, and where possible, encourage recycling.

Adolfo Suárez Madrid-Barajas airport has three selective collection areas at T123 – two on the platform and one in the built area – and five in the extension area - four in the T4 terminal building and the fifth in the satellite building (TS4). They are all equipped with different containers for each type of waste and are labelled appropriately.

Since 2006, the airport has also had a Transfer Station and Recycling Point for solid waste, where the waste is treated and stored before recycling or valorisation.

The waste is classified as:

  • Hazardous waste constitutes approximately 5% of the total, mostly generated by the maintenance of premises and equipment. Includes batteries, fluorescent lights, electronic and electrical equipment, filters, used oil, antifreeze and liquids with hydrocarbons. To maximise security, this type of waste is collected by a single waste treatment company in accordance with current legislation.
  • Non-hazardous or urban waste: collected selectively for subsequent recycling. Consists of ordinary refuse, liquids and substances of a similar consistency, paper, cardboard, glass, tyres, wood, metal, plant remains, etc. The amount of paper and cardboard alone accounts annually for more than four hundred tonnes.
