Graytec Global’s goal is to set a higher standard of in-building water use in the same vein as to how LEED Architecture raised the bar for energy efficient design.

Graytec AB is a Swedish clean technology firm that has invented the internationally patent-pending Blue Circle System; a closed-loop, circular water purification system that intakes greywater from bathroom sinks, bathtubs, and showers, and then recycles it into warm, potable water before redirecting that purified water back into those same bathroom sinks, bathtubs, and showers for direct reuse. Within buildings, our technology saves users up to 60% of total water used and up to 80% off of the energy required to heat that water. Founded in 2016, Graytec AB entered the Swedish market in 2020.

Graytec USA is Graytec AB’s sister company that will work with American regulators to allow for mass use of our technology. Meanwhile, Graytec USA will sell the Blue Circle System to non-grid connected developments that are allowed to utilize our technology. Founded in 2019, Graytec USA will enter the American market in 2021, while exporting to foreign markets that same year.

​Our target verticals include multi-unit residential buildings, hospitals, prisons, and military bases. However, our solution is compatible with any structure that creates greywater from showers, bathtubs, and bathroom sinks!

​We invite you to go blue with us, one building at a time.
