sau nhiều năm hạn hán lịch sử ở California, 2 thanh niên sáng chế ra bia làm từ... nước tái chế...

After years of historic drought (hạn hán) in California, water recycling has become a pressing (cấp bách) issue – but just how much can be done with what we’ve got?

Epic OneWater Brew, from Epic Cleantec and Devil’s Canyon Brewing Company, is made from greywater (nước thải sinh hoạt, trừ nước thải từ nhà vệ sinh) recycled from showers, laundry and bathroom sinks in a 40-story San Francisco apartment building, where Epic has onsite equipment to capture, treat and reuse water for non-drinking purposes.

You won’t find the beer for sale anytime soon. Epic has been open about the fact that it’s a “demonstration (thuyết minh) product”: the company’s goal is to get people talking about the possibilities of water recycling, and current commercial regulations on recycled drinking water are strict.

“We wanted to do something fun that was going to be an engaging tool to talk to people, to get them excited, but also that showcased the untapped (chưa khai thác) potential of water reuse,” said Aaron Tartakovsky, Epic Cleantec’s co-founder and CEO.
