The best things in life are free? The truth will set you free? There's no such thing as a free lunch? The free sayings go on and on but how do they apply to free beer? At the United Nations climate talks among all the big flashy signs sits small cans of New Brew at the Singapore display and those cans of beer are free. The people who stop to sample New Brew are mostly surprised to find it is made with treated wastewater which is the point of the climate talks in the first place, learning how to stretch the Earth's limited resources, one of which is water. Some of the conference attendees refer to the beverage as sewage beer but not many people are turning down the free beer even after they know how it's made.
