We are newGreta, the future of us all.

newGreta s.r.o. transforms problems into value. For us, waste is not the end, but a raw material. Our internationally patented technology—based on more than a decade of experience in the development and testing of building materials—transforms crushed mixed municipal, industrial, and construction waste (excluding biological waste) into fully-fledged building elements.

The waste is turned into bricks, blocks, interlocking paving, street furniture, and curbs ready for real-world use. We are a Czech company founded in 2023, and we are proving that circular construction can be fast, reliable, and economically viable.

About us

newGreta s.r.o

The key element of newGreta's unique technology is a binder that holds the waste material together without the need for high-temperature firing. This production process is therefore energy-efficient and harmless to health. The products have passed all the necessary tests: compressive strength, frost resistance, water absorption, non-flammability, slip resistance, abrasion resistance, and long-term durability. The test results are, of course, verifiable. newGreta cooperates with certified laboratories and is developing capacities for semi-industrial and large-scale production. 

One of the founders of newGreta is inventor Petr Španiel, who, together with a team of experts, has been working on the development of new building materials and systems for a long time. The result is a technology that allows the processing of waste that would otherwise end up in landfills or incinerators, including non-recyclable plastics, cinders, composite material residues, and wind turbine blades.
