No Flow Toilets
In North America, we spend a lot of money to purify water to drinking water standards in order to flush it back down the toilet. It is an incredibly costly and wasteful endeavor and is one of the largest uses of water in our households. I could not helped but be intrigued and inspired by this challenge put out by the Bill and Melinda Gates Foundation. It’s a solution that allows for waterless toilets that additionally recycle human waste.
