The ridiculous story of airline food and why so much ends up in landfill

Airlines generated 5.2m tonnes of waste in 2016, most of which went to landfill or incineration - and it cost them 400m

You probably know about the waste problem in our oceans. But how about the one in our skies?

Airline passengers generated 5.2m tonnes of waste in 2016, most of which went to landfill or incineration, the International Air Transport Association (IATA) estimates. That's the weight of about 2.6m cars. And it's a figure set to double over the next 15 years.
