Material Balance

Fundamental Approach

The Nittobo Group consumes fuel, electricity, and other energy sources to manufacture a wide range of products with natural resources and chemical substances as raw materials. Major environmental impacts include carbon dioxide generated as a result of energy consumption, chemical substances that are discharged to the environment without being collected, and other waste. The Nittobo Group is striving to reduce these environmental impacts by adopting renewable energy, promoting energy conservation, and engaging in resource cycle initiatives.
