Bringing education and knowledge to where people need it and where sustainability is born. This is the goal of S³ - Scientific Solutions for Sustainability. The project promotes social engagement of students and young researchers in the field of sustainable development. The idea for this project was born while the founders of S³ did their own research at the university. There, numerous practical ideas have emerged that go beyond the pure scientific work and thus have little chance of implementation with the help of research funds. S³ wants to strengthen such ideas, to be a platform for exchange and to create a professional network that helps to implement even small concrete projects aimed at sustainable development.
