By adding silver nano particles to paper, a filter is obtained that purifies water to make it drinkable water up to our standards. The McGill University and Carnegie Mellon University have developed an innovative way by which sheets of paper function as a filter for contaminated water. These sheets of paper are put together in the Drinkable Book.
When contaminated water is poured upon the paper, it is being filtered to the US EPA guidelines for bacteria removal to produce safe drinking water. This simple process offers major benefits to those living in situations with absence of clean drinking water. One sheet of paper, called pAge drinking paper, can provide up to 30 days of clean water. And the "Drinkable Book" can provide its users up to 4 years of drinkable clean water. Producing a sheet of paper cost "pennies' the develop say Dr. Theresa Dankovich and Dr. Jonathan Levine, the developers of the Drinkable book. They launched a crowdfunding action to obtain funds for the production of 1000 books with a total of 25.000 pAge paper filters. Please watch the video about this paper innovation here.
The idea received a Gold Lion at the Cannes Lions Advertising Festival for Creativity as proof of the value of the idea.
