Humanitarian group Water is Life has created a book made of water-purifying filter paper to provide safe drinking water for people in developing countries.
Created in collaboration with scientists from Carnegie Mellon and the University of West Virginia in the US, the book is designed to provide an individual with clean water for four years. It contains information on safe water habits printed on a new, low-cost form of filtration paper made with silver nanoparticles, which kills 99.9% of water-borne bacteria, including cholera, E. coli and typhoid.
More than three million people die each year from water-related diseases, but new methods to provide communities with safe, filtered water are proliferating. Last year, researchers at the University of Engineering and Technology (UTEC) in Lima, Peru, collaborated with global advertising agency Mayo Draftfcb to create a billboard that produces drinking water from humidity in the air.
Across the world, water scarcity is becoming an increasingly crucial issue. For more on how forward-thinking companies are cutting and eliminating water usage, see Doing Without Water.
