Sustainable flags from Rotterdam
We are modern flag makers with an old soul and a new mission: sustainable flags! For generations, our flags have proudly flown the identity of companies, countries and cities. We believe in the power of the flag as an age-old symbol of independence and pride. Just as a semaphore with 2 flags could send a message at lightning speed over long distances, so our flags now make such a powerful statement. Flags and signs are a beautiful and effective low-tech communication tool in a high-tech society. In that society we were the first to make real sustainable flags in 2017: Semaphore PETflag. Flags made of 100% recycled PET fibers.
In 2024 we started developing the next step in sustainable signing: flags and signs made of hemp fiber and biodegradable resins. The results are promising, but our HEMPflags are not ready for market yet. We need some time to develop the perfect textile for the dynamics of outdoor flying flags. We expect to present our first HEMPflag products mid 2025.

Highlights

Sustainable flags
In 2017 we were the first in the world to use recycled PET material as a cloth for our flags, banners and banners. In the meantime, we are no longer the only one, but thanks to the lead in this innovation, Semaphore is the preferred supplier of international sustainability organizations. Sustainability is the guiding principle in our business operations and we compensate the production of our flags with a linked donation to FEE's Global Forrest Fund.
