Qantas have made history after taking to the skies this morning in the world's first zero waste commercial flight.

But in order to pull off the feat, they've had to scrap or refashion some of the items customers have come to expect from the airline.

The QF737 service, which travelled from Sydney to Adelaide, produced no landfill waste as part of a company wide commitment to cut 100 million single-use plastics by the end of 2020, and reduce waste by 75 per cent by the end of 2021.

All in-flight products can be reused, recycled or disposed of via compost, according to a statement from the airline, and the flight will also be 100 per cent carbon offset.

The airline teamed up with composting solutions company BioPak to pull off the ground-breaking flight.

Qantas domestic CEO Andrew David said the flight was about "testing our products, refining the waste process and getting feedback from our customers."

"Qantas and Jetstar currently produce an amount of waste equivalent to 80 fully-laden Boeing 747 jumbo jets," Mr David said.

"We want to give customers the same level of service they currently enjoy, but without the amount of waste that comes with it."

The Sydney to Adelaide flight would typically produce 34 kilograms of waste, according to Mr David, which is 150 tonnes annually.

Whittling the waste down to zero for the service involved substituting around 1000 single-use plastic items for more sustainable options — or simply removing them from the flight altogether.

Yep, you can soon say goodbye to those individually-package portions of milk and Vegemite, in place of more sustainable alternatives.

Curious as to what your in-flight meals will be served on? Passengers can look forward to containers made from sugar cane and cutlery made from crop starch, both of which are compostable.

Even Qantas' customers went 'green' for the trial flight, using digital boarding passes and e-tags for baggage where possible, with staff on-hand to ensure any paper passes and tags were disposed of sustainably.

Ultimately, the environmental benefit does hinge on the additional clean-up efforts of cabin crew, who'll be charged with sorting all leftover items into different recycling and waste streams once the flight is over.

While the zero waste flight is a step in the right direction, there's more hard work to come -- in order to honour the company's pledge to remove 100 million single-use plastic items every year by the end of 2020, Qantas and Jetstar will have to replace 45 million plastic cups, 30 millions cutlery sets, 21 million coffee cups and 4 million headrest covers with sustainable alternatives.

The airline will also be offering passengers 10 Qantas Points for every dollar spent offsetting their carbon commissions from mid-2019.
