Australian Stockholm Junior Water Prize past winners

2021 Winner

Annabelle Strachan, Meriden School

Annabelle Strachan

 
Annabelle’s study investigated the feasibility of a bio-flocculant as an accessible, safe, affordable and environmentally friendly option to reduce turbidity. Using a combination of dried lemon peel and chitosan, Annabelle tested different concentrations to find the optimal dosages to reduce turbidity. The bio-flocculant identified offered an affordable treatment option for those with limited access to clean water while being environmentally friendly and offering no adverse health effects sometimes associated with flocculation.

2020 Winner

2020 Winner - Emma Serisier, Bishop Druitt College

Emma Serisier

 
Emma’s study looked at potential biowaste adsorbents to decrease the phosphate run-off into natural waterways from agricultural fertilisers and animal manures. Identifying eggshell waste as an effective adsorbent for phosphate, Emma developed a mathematical model and website for farmers to calculate cost savings and application rates of eggshell on their soils. This free and accessible tool will help farmers counteract their environmental footprint.

2019 Winner


Macinley Butson, The Illawarra Grammar School, New South Wales

2019 Winner: Macinley Butson

The SODIS Sticker: Development and testing of a Film based detector system for appropriate Ultraviolet Solar Disinfection (SODIS) of Water

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.

Minh Nga Nguyen - Award

Recycling Waste into Biochar: A Sustainable Wastewater Filter and Fertiliser for the Agricultural Industry

Minh Nga Nguyen, Sydney Girls High School (NSW)
Nga’s project is entitled “Recycling Waste into Biochar”, a sustainable waste water filter and fertilizer for the agricultural industry. Her project formed a model of application in which agricultural plant wastes are recycled into a multipurpose biochar charcoal, that can filter wastewater and fertilise plants. Nga found that bamboo biochar filter packs could remove 45.6% of harmful pollutants in wastewater, lowering pollutant content to meeting Australian guidelines. Her findings have the potential for application in the agricultural industry, allowing farmers to recover polluting plant wastes and turn it into biochar used to treat livestock wastewater, as well as aid crop growth.

2017 Winner


Macinley Butson, The Illawarra Grammar School, New South Wales

Macinley’s project involved the design and testing of a simple and affordable mechanical device to help solve the problems of clean water and power for people in developing communities. The Solar System, which produces solar energy, provides a supply of clean potable water for personal use as well as a sterile water supply for medical use. Macinley’s invention has the potential to help many people around the world as it can increase green energy power generation by over 70% per day and supply clean water daily.

2016 Winner


Mohamed Jakaria, Queensland Academies Health Science Campus, Southport, Queensland

Mohamed’s investigation examined the efficiency of Elodea canadensis in removing nitrate in effluent discharged from wastewater treatment plants. This was explored by answering the research question: What is the effect of increasing surface area of Elodea canadensis on the assimilation of nitrate in effluent discharged from Beenleigh wastewater treatment plant? This autotrophic aquatic plant’s ability to use inorganic nitrogen for growth provides an ecologically friendly solution to the tertiary treatment of wastewater.
