IT TAKES 1.4 kilowatts of energy to burn a poo.
The loo with no water could be a more palatable answer to drinking recycled sewerage for drought-stricken towns.
Designed in Norway and debuted at AgQuip, the Cinderella Incineration Toilet turns turds into ash at 550 degrees.
It's a very real potential solution to save water in drought, owners Anette and Darren Helleren said.
"A family of four will use 448 litres of water per week just flushing the toilet," Mrs Helleren said.
"The environmental impact is we aren't using any water, we don't need a septic system and we don't need to hook up to a sewerage system either.
"And the whole issue with nappy wipes and hygiene products going down the toilet, this burns them."
The toilet was developed in rocky areas of Norway where it wasn't possible to install a septic system.
The idea was born out of a need to find an alternative to dropping waste in the ocean from ships.
It can run on electricity or gas, for people who live in rural areas off the grid.
It's taken the Hellerans four years to bring the red-hot loo to Australia; now they hope to start an education process and set up across the country.
Burned at 550 degrees, the ash that comes out the other end still retains some nutrients, Mr Helleran said.
"It means you can put it in the garden, in the compost, or in the bin," he said.
"But there's no bad bacteria or pathogens in there, compared to a compost toilet where you could get sick - this is healthier in that respect."
Incineration toilets could be a more palatable and environmentally friendly solution - but, at $7000 a unit, it's not cost-effective for everyone.
