It is a fully biodegradable and eco-friendly system for hydroponic agriculture, made of hydrogel and capable of supporting plant growth with minimal water; in the future, it will be able to monitor plant health in real time. This innovation is the result of joint research between the Faculty of Engineering at the Free University of Bozen-Bolzano (UniBz) and the Istituto Italiano di Tecnologia (IIT-Italian Institute of Technology) in Genoa. The invention offers a zero-waste, low-environmental-impact solution for agriculture, a sector increasingly threatened by climate change, drought, pollution, biodiversity loss, and soil degradation.
