Graytec Global is the website that represents the Graytec Companies, Sweden's Graytec AB and Graytec USA.

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, and our company may export to regulation-friendly foreign markets shortly thereafter.​

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 no later than 2021, and this company plans to export its product to regulation-friendly foreign markets this year as well.

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