Using a rest room pays to your espresso or purchase you bananas at a college in South Korea, the place human waste is getting used to assist energy a constructing.

“If we think out of the box, faeces has precious value to make energy and manure. I have put this value into ecological circulation,” Cho stated. An common individual defecates about 500g a day, which will be transformed to 50 litres of methane fuel, the environmental engineer stated.

Students can use the forex to purchase items on campus, from freshly brewed espresso to prompt cup noodles, fruits and books. The college students can choose up the merchandise they need at a store and scan a QR code to pay with Ggool.
“I had only ever thought that faeces are dirty, but now it is a treasure of great value to me,” postgraduate scholar Heo Hui-jin stated on the Ggool market. “I even talk about faeces during mealtimes to think about buying any book I want.”
