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


Closed-loop system

Bemberg is a regenerated cellulose fiber made from cotton linter. Since our foundation, we strictly control the chemical substances used in the manufacturing process and have introduced a closed-loop production system that recovers and reuses copper and ammonia. We have been making improvements further even now.

Initiatives for carbon neutrality

GHG emissions—Goals of Asahi Kasei Group

By 2050
carbon neutral
By 2030
emissions reduction of 30% or more (from fiscal 2013)

To achieve the goals, we conduct following efforts.

  • 01
    Energy decarbonation
  • 02
    Emission reduction in the manufacturing process
  • 03
    Manufacturing process innovation

Energy decarbonation

Since the foundation, we have been in the business of transmitting electric power from our own hydroelectric plants, and currently own nine power stations in total.
By improving the efficiency of these generators, we will reduce CO2 emissions by approximately 11,000 tons annually and aim to further reduce the environmental impact.

We installed a biomass power generation in 2012 to increase renewable energy ratio. We replaced a coal power plant with a natural gas (LNG) power plant, which has been in operation since March 2022. This will reduce CO2 emissions by approximately 160,000 tons annually and lower the environmental impact.

Energy composition in Asahi Kasei Nobeoka



Bemberg is a regenerated cellulose fiber that uses 100% cotton linter—a pre-consumer material obtained from the manufacturing process of cottonseed oil. It is an environment-friendly material that is biodegradable and compostable for circularity, and undergoes environment-friendly production that includes a proprietary closed-loop system enabling recovery and reuse of major chemicals, while achieving zero emissions of waste.
