According to the International Air Transport Association, airlines produced 5.2 million tons of waste last year, and will produce over 10 million tons annually by 2030. Moreover, recent data from Eurostat revealed that up to 36% of the air passenger transport in Europe has extra EU destinations, and could be considered as international flights where regulation for Category 1 waste must be considered for catering waste that is produced on-board (i.e. international catering waste, or ICW). ICW is currently disposed of by incineration or landfilling, which involve great environmental impact compared to other management alternatives. Therefore, developing a feasible solution for waste reduction and waste valorization into renewable energy in aircrafts is crucial to accomplishing the target for Key Performance Indicator “Reduce Aircraft CO2 emissions”.

The main objective of the project is the implementation of an Anaerobic Digester Prototype (ADP) ready for aircraft testing that will allow for waste management valorization and reduction of sewage and waste and for minimizing the ecological footprint of commercial flights.
