2018 Winner: Minh Nga Nguyen, Sydney Girls High School, New South Wales
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.

The Australian Stockholm Junior Water Prize was awarded at Ozwater’17 in Sydney. Watch the video below and hear what Macinley said about winning the award:
In our second video Macinley shares with us her Australian Stockholm Junior Water Prize experience:
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.
