How it started

We were captivated by the breathtaking Aurora Borealis like swirling rivers which was the most fascinating phenomenon they ever experienced in our lives.

Being the world’s most sustainable countries, the Scandinavian region has taught us that the Earth is beautiful, fragile and needs to be protected. The “ÖKO” in ÖKOSIX® means “ECO” in Scandinavian.

Having technical and professional backgrounds, we believe that technology is key to change the world and bring a better life and environment.

In Feb 2020, there was a serious shortage of face masks in Hong Kong during the COVID-19 outbreak. Therefore, one of our founding team decided to start a company to manufacture masks in Hong Kong.

As the pandemic persisted, the production of masks kept increasing and the factory was expanded. However, this actually raised an alarm - the disposal problem of used face masks.

The team has been looking for sustainable materials for making fully biodegradable and medical face masks. However they realized that such a product does not exist. Therefore they decided to invent it! This is how ÖKOSIX® was born.
