Noemi Florea is the inventor of Cycleau, a compact system that turns greywater into drinking water. Using a four-stage treatment process, it removes over 200 contaminants, reduces building water footprints by up to 80 per cent and lowers energy demand by more than a third, all at a fraction of the cost of conventional systems. Cycleau has been piloted in projects ranging from a public bottle filling station in the United States of America, to schools along the Tajikistan–Afghanistan border. By capturing and recycling water close to where it is consumed, the system reduces pollution, conserves resources and supports safe, affordable water access.

Florea is an internationally recognized youth climate innovator selected among the top 1 per cent of youth innovators under 24 by MIT Solve, highlighted by UNICEF as one of 20 youth innovators at the 28th United Nations Climate Change Conference, and awarded the Women in ClimateTech Award in 2024. Florea has also won prizes from the Swarovski Foundation, HP, the Halcyon Incubator and the Trust for Governors Island.
