Pinelands High school matric pupils, Matthew Redfern and Joseph Gibbon, will participate in an international festival of engineering science and technology, I-Fest², to be held in Mahdia, Tunisia, from Thursday March 16 to Wednesday March March 22. The duo impressed judges at the Eskom Expo International Science Fair in December, where they bagged a gold medal for their research, along with the top senior category award in the “chemistry and biochemistry” category. Their research project, “Comparing and evaluating different types of bioplastic polymers – an investigation into bioplastics”, seeks to mitigate the impact of plastic pollution. Pinelands High had a send-off for the two pupils on Tuesday.
