Zaak Technologies in Großbeeren is something like the headquarters of the new company. From there, Abbas Khan is looking for partners and licensees all over the world for his unique idea and his previously unique product. In the Großbeeren warehouse he can produce between one and two tons of construction sand per day.
“That might be enough if a company wants to try it out, but there is no room here for larger quantities,” he says. Large production plants are not even the goal of Zaak Technologies, at least not in Großbeeren. “This is our innovation center,” he says, embracing the chemical plant and the laboratory with wide arms.
Ashes turn into building gold
Abbas Khan did his doctorate in physical chemistry in Heidelberg. He then worked in Australia for a while, and came up with the idea for his upcycling product in India when he noticed a construction site there that was no longer being worked because there was no sand. He has had the patent for the process with which he turns ashes building gold since 2016. Abbas Khan calls his sand Lypors.
Lypors looks like brown sugar. The Lypors samples, which are stored as demonstration objects in the hall, are relatively coarse-grained material, but with which you can see and feel the corners and edges that are needed for further use in building materials. “Of course, you can also choose the grain size differently, it’s just about one thing: This is a unique, artificial material of the circular economy,” he says. And apart from the fact that Lypors is fully recyclable, a lack of ash from coal-fired power plants is hard to imagine. Billions of tons are stored in landfills around the world, and new ash is produced every day. Khan’s invention can also contribute to the gradual disappearance of power plant ash landfills.
After the plant for the production of the building sand was finally up and running last year, the young entrepreneurial family wanted to really get started. But as with numerous other companies, the global pandemic thwarted all plans at Zaak Technologies.
“We already had appointments with interested partners who came here and wanted to see everything,” says Jana Martin. “Then the borders were closed.” The temporary liberalization of travel conditions did not help either. “Because anyone who would have wanted to see this would have had to be in quarantine for two weeks,” adds Martin. With such a new product, Zoom conferences are hardly enough.
