Wastewater recycling on the ISS and in Singapore

 

How would you feel about drinking your own urine? To most, it is a measure that would only be taken in the direst of circumstances. However, astronauts on the International Space Station (ISS) have been drinking recycled urine every day for the past decade. In 2008, the ISS installed the Water Recovery System, a wastewater recycling device which converts urine, sweat, and atmospheric moisture into drinking water. This device has allowed the ISS to be much more self-sufficient and devices like it could serve to more sustainably produce clean water on Earth.
