We endeavor to realize a sustainable society from various perspective,
with our transparent raw material and closed-loop production system.


On our planet, various changes are required to realize a sustainable society.

In the fashion industry as well, it is important to reduce the environmental impact and build a business model that solves social problems, from the perspectives of raw materials, production processes, and final products.

Under such circumstances, Bemberg has been changed to be more sustainable by establishing transparent procurement routes and introducing the closed-loop production system.

Since our founding, we have always adapted to the times and created new solutions. We will respect such our DNA and conduct what only Bemberg could do.


The raw material of Bemberg is cotton linter* that is a pre-consumer material obtained from manufacturing process of cottonseed oil.
Bemberg is biodegradable and compostable fiber.

*Short downy fiber enfolding cotton seeds


Reducing CO2 emissions via renewable energy and introducing a closed-loop production system, we have established the environment-friendly and traceable production system.


We collaborate with various stakeholders to realize a sustainable society, pursuing both solutions to societal issues and economic gains.
