The True Green and Green Lanes – The Heart of Strumber Innovation

Strumber is the result of work by The True Green, a company established within the Green Lanes ecosystem. This is where groundbreaking solutions are born, transforming annual plants into materials of the future. Our team includes experienced agronomists, chemists, biotechnologists, and managers, who work daily to ensure Strumber meets the highest industry standards.

Our research and development center features an in-house laboratory where proprietary technologies are created. The results are implemented directly in our production facility, enabling us to commercialize and scale Strumber efficiently and sustainably.
