The Helmet Born
from Scallop Shells
Scallops are the shellfish
that Japanese people eat the most.
It was also the shellfish
whose shells were discarded the most.
Could shells, which used
to protect from outside enemies,
be transformed into something
that protects people's lives?
We at Koshi Chemical
new life into
these discarded scallop shells.
A completely new helmet,
strong and gentle, is born.
The more that are made,
the more beautiful
the sea becomes.
Shellmet upcycles scallop shells that would have
otherwise been discarded. In addition,
by using bioplasticmade from scallop shells as raw material,
CO2 emissions are reduced by approximately 50%,
making the helmet environmentally friendly.
Created by nature,
Based on the idea of biomimicry,
Shellmet incorporates a special rib structure
in its design that mimics the structure of scallops,
which are part of the material.
As a result,we have achieved
a strength approximately 33% greater than normal.
product designed by quantum
Good to use again and again.
So it’s also good for the earth.
After the lifecycle of the HOTAMET,
they can be recycled
as building material
or as material to produce new
Our goal is to contribute to a sustainable
society by creating a system in which discarded
be used perpetually,
rather than just recycling once.
Available in 5 colors: white,
beige, black, blue, and pink
Shellmet transforms shells - which originally protected against external enemies - into something that protects human life. Therefore, it is made of almost 100% recycled materials, which is in line with the recent social trend away from plastics. Another feature of this product is that the more it is produced, the less shells are discarded.
At first glance, picking up detritus in the ocean and recycling may seem to be two different things, but I believe they are fundamentally the same. In this respect, wearing a Shellmet can be considered an activity to protect the ocean in a larger sense. I hope that this Shellmet will help raise the environmental awareness of many people.
