HMS Prince of Wales' waste system (Picture: Royal Navy).
Personnel on Britain's newest aircraft carrier are testing a state-of-the-art green waste disposal system.
Pyrolysis plants on HMS Prince of Wales are being used to reduce the amount of rubbish generated by 100 times.
Extreme heat from a burner reaching temperatures of more than 1,000°C breaks down the material generated by 600 sailors and 400 industry engineers and experts.
This includes food, sewage and excess oils, which contribute to a total of upwards of nine tonnes every day.
The waste is converted into fuel, which then sustains the plants, meaning the burner can be switched off and used sparingly.
The machines are already on board her older sister, HMS Queen Elizabeth.
Marine Engineering Technician Niall Kelleher, one of the junior sailors responsible for the plants' operations, said: "The plants’ waste reduction ratio will benefit the ship’s company with us having far less waste to dispose of during 'out all gash' – and enable us to store the waste far easier."
HMS Prince of Wales is currently conducting trials in the North Sea.
