During summer 2018 two young scientists, Yasemine and Hannah (HLUW Yspertal) worked on the topic “micro plastics in front of our doors”. The two girls analysed the content of micro plastic of the river Ybbs and its degradability in sludge. Their work was nominated for the Bundesfinale Jungendinnovativ (for further information see: https://www.jugendinnovativ.at/news/beitrag/news/siegerinnen-und-sieger-2018-ausgezeichnet-1/). The two girls used the opportunity to show themselves at their best! In the end they were crowned with success: they won the 1.prize in the category Science. Now, Yasemine and Hannah are going the represent Austria at the China Adolescents Science & Technology Innovation Contest 2019 in Macao (20.7.–26.7.2019) and in addition to that at the European Union Contest for Young Scientists in Sofia (13.09.–18.09.2019). Good luck, girls!
