SHELLMET｜Protect Heads, and the Earth

In the bustling streets of Japan, where tradition meets innovation, there’s a quiet revolution taking place—one that transforms discarded scallop shells into a powerful shield for life: Shellmet. At Koushi Chemical, we’re rewriting the story of these once-overlooked shells, turning them into a symbol of protection and sustainability.

From Waste to Wonder

Scallops, once a staple of Japanese cuisine, often left behind a trail of discarded shells. But what if these shells, once protectors from the ocean’s depths, could safeguard lives in a new way? Shellmet breathes new life into these shells, upcycling them into a completely new form: a helmet that’s both strong and gentle.

Environmental Innovation

Shellmet isn’t just about protection—it’s about preserving our planet for future generations. By utilizing our proprietary bioplastic, “Shellstic,” derived from scallop shells, we’ve slashed CO2 emissions by approximately 50%, making each helmet a beacon of environmental responsibility.

Inspired by Nature

Nature has always been the greatest innovator, and Shellmet is no exception. Drawing inspiration from the intricate rib structure of scallops, we’ve integrated a special rib design into Shellmet, boosting its strength by an impressive 33%. It’s biomimicry at its finest—a testament to the power of nature-inspired engineering.
