Meet our Australian Stockholm Junior Water Prize Winner for 2019 and the Internation Stockholm Junior Water Prize 2019 Winner
The SODIS Sticker: Development and testing of a Film based detector system for appropriate Ultraviolet Solar Disinfection (SODIS) of Water
Macinley Butson, The Illawarra Grammar School
Macinley has developed the SODIS sticker, an innovative ultraviolet radiation sticker which accurately measures the solar UV exposure required to sanitise drinking water. This is done through a high accuracy transparent UV-sensitive film coupled with a partially UV blocking filter, which allows the SODIS sticker to measure direct UV exposure from the sun and reflected UV from other objects. At just over one cent to produce, it is also a cost-effective and safe way of purifying drinking water for developing communities
Following Macinley winning the Australian Stockholm Junior Water Prize in May 2019, she went on to take home the International Stockholm Junior Water Prize in August 2019. The Prize was presented to Macinley by HRH Crown Princess Victoria of Sweden. Read more here about Macinley's win in Stockholm
