“Blue~Black~Grey? What if it was all just water?”

November 10, 2020 @ 9:00 am – 10:00 am

Graytec Global is the banner representing the Graytec companies – Sweden’s Graytec AB and Graytec USA.

Graytec AB invented the Blue Circle System at Chalmers University of Technology in Gothenburg as a response to increasing droughts and worsening quality of waters throughout the world.

The Blue Circle System conserves up to 60% of the water used within a home while also saving up to 80% off the energy used to heat waters used in bathrooms. This is done by piping greywater used in bathtubs, showers, and bathroom sinks into our onsite system that recycles greywater to potable quality before circulating that water into those same showers, bathtubs and bathroom sinks for direct reuse by its occupants.

Graytec AB was founded in Gothenburg, Sweden in 2016, where four of its five co-owners live.

Graytec AB’s successfully tested prototype was developed and launched at Chalmers University of Technology’s HSB Living Lab, which is also located in Gothenburg.

Graytec USA was founded in 2019 in Scottsdale, Arizona. The University of Arizona invited Graytec USA to join its incubator that same year. Luke Jackson is the sole American representing the Graytec companies.
