Officials at an Australian skiing resort are recycling sewage into snow “so clean you could eat it”.

“There are as many as 200,000 visitors to the resort every day during the skiing season and they produce about one million litres of waste water every day,” says David Westphalen, manager at the Mount Buller resort near Melbourne.

“Water is a scarce commodity in Australia so we have developed a system that can take this waste water, clean it and turn it into snow that is indistinguishable from normal snow. I see it as a way to minimise waste,” he says.
