Reduction of Environmental Burden Sustainability

Reduction of Environmental Burden

To help conserve the global environment, the Kurabo Group is aggressively implementing environmental measures in various areas, including global warming, air, water, and waste.

Prevention of Global Warming

In addition to conducting energy-saving activities, the Group works on reduction of greenhouse gas (CO₂) by utilizing renewable energy and changing fuel from heavy oil to gas. We are also planting trees and flowers on factory premises. In addition, with liberalization of the retail electric power market, we evaluate environmental aspects (such as the CO₂ emissions factor) when selecting a power company to provide us with electricity.
The total CO₂ emissions of the Kurabo Group are on the decline in the medium-to-long term, although the amount of reductions varies year by year. In fiscal 2018, CO₂ emissions decreased significantly as described above. We reduced emissions by 7.2% compared with the previous year, and the average was 4.3% over the past five years. Kurabo by itself has reduced CO₂ emissions by 76.0% compared to fiscal 1990.

Prevention of Air Pollution and Water Pollution

We strive to reduce our environmental burden in order to prevent air pollution and water pollution. Regarding air pollutants, the amount of sulfur oxides (SOx)*1 is on the decline thanks to the shift to fuel gas. Nitrogen oxides (NOx)*1 increased significantly in fiscal 2018 due to the inclusion of data from the Tokushima Biomass Power Plant. As for water pollution, the waste water treatment load of the Tokushima Plant decreased in fiscal 2018, thus reducing chemical oxygen demand (COD)*2 emissions.

Amount of Air Pollutants


COD Emissions (dye processing plants)


  • *1: SOx, NOx: Generic terms for sulfur oxides and nitrogen oxides. Typical air pollutants generated by combustion of fossil fuel.
  • *2: COD: Chemical oxygen demand. Amount of oxygen required to purify waste water. An indicator of water contamination.

Waste Reduction and Pursuit of Zero Emissions*

We have been setting zero emissions as an environmental target and working to recycle waste in efforts to contribute to the realization of a recycling-oriented society. We have achieved significant results thanks to long-term efforts; however, the overall recycling rate has declined due to slow progress at the Tokushima Biomass Power Plant, which became fully operational in fiscal 2018.
