Reinventing Materials for a Greener Future

Plastic pollution is one of the defining environmental challenges of our time.

While plastics have enabled modern healthcare and everyday convenience, their persistence in the environment has created a growing ecological and human health burden. This challenge is especially acute in healthcare, where single-use plastics are essential for safety and hygiene, yet generate vast amounts of largely non-recyclable waste.

OKOsix was founded to address this challenge at its root: by rethinking and reinventing the materials.

We develop next-generation, fully biodegradable or durable alternatives to fossil-based plastics that deliver the performance required for disposable or resuable applications, without leaving a lasting environmental footprint.

How We Started

OKOsix began in early 2020, when Hong Kong faced a critical shortage of face masks at the height of the COVID-19 outbreak.

Determined to take it in action, our founder Eddie Yu started manufacturing masks locally to meet urgent demand. The business grew quickly and was eventually sold at its peak, but the experience led Eddie to an unexpected question that would change everything.

The turning point came from Eddie’s five-year-old niece, Zoe. While teaching her how to sort waste for recycling, Eddie explained which materials went into which bins.

Zoe paused, then asked a simple question: “Uncle Eddie, where do we put your face masks?” When Eddie explained that masks couldn’t be recycled, she replied bluntly, “But you make a lot of trash every day. That’s not eco-friendly!”

That moment stayed with him. With over a decade of experience in materials research, including biodegradable materials, Eddie realized the real problem wasn’t disposables—it was the materials behind them. Why couldn’t essential products like face masks be made from natural materials to safely return to nature?

That question became the foundation of OKOsix. Sometimes, the clearest wake-up calls, and the boldest ideas, come from the smallest, most honest voices.
