Sustainability guru and restaurateur Joost Bakker will be harnessing pee-power at this year's Melbourne Food and Wine Festival, where visitors to his pop-up restaurant will have their urine harvested to help power it for next year.
The Greenhouse pop-up restaurant will be powered off mustard seed oil and diners' urine will be transported to a farm and injected into the soil as fertiliser to help develop the oil for future Food and Wine Festivals.
The concept forms part of a five year collaboration between Bakker and the Festival.
"We're building a waterless female urinal, and of course waterless male urinals already exist, and that [urine] gets diverted into a storage tank that goes straight to the farm and then the farmer’s got a way of directly injecting it into the soil as fertilizer," Bakker told Hospitality.
The pop-up restaurant, apart from its chargrill and woodfired pizza oven, will be run completely off mustard seed oil, and forms part of Bakker's commitment to showing Australians how to live - and eat - more sustainably.
"It's mainly to show people that there's no such thing as waste. Everything has a value," he said.
And while some might find his new form of energy generation somewhat unpalatable, Bakker says it'll be far more common in the future.
"I think in the future everyone will do it. I think in 15 or 20 years, everyone will be harvesting urine. Because at the moment one third of the world's gas is used to create fertiliser for agriculture so it's just not sustainable to do it that way, and yet we’ve got 7 billion people creating fertiliser every day of the week so it just makes sense to use it".
