Urban and Environmental Engineering Professor Cho Jae-wen at Ulsan National Institute of Science and Technology (UNIST) has designed an eco-friendly bathroom hooked up to a laboratory that makes use of excrement to supply biogas and compost.
The BV bathroom – a portmanteau of beehive and sight phrases – makes use of a vacuum pump to ship faeces to an underground tank, lowering water utilization. There, microorganisms break down the waste into methane, which turns into a supply of power for the constructing, powering fuel stoves, scorching water boilers and stable oxide gas cells.

Cho has created a digital forex referred to as Ggool, which implies honey in Korean. Every individual utilizing eco-friendly bathroom earns 10 Ggool per day. Students can use this forex to purchase the whole lot from freshly brewed espresso to instantaneous cup noodles, fruits and books on campus. Students can decide up the merchandise they need from the store and scan the QR code to pay with Ggool.
“I once thought that feces was dirty, but now it’s a very valuable treasure to me,” mentioned postgraduate pupil Heo Hui-jin on the googol market. “I even talk about stool during meals so I can think about buying the book I want.”
