Initiatives to Reduce Environmental Impact

Promote Energy Conservation

Our Energy Management Committee promotes companywide energy plans, including the adoption of new energysaving technologies.

We have also positioned dedicated efforts to reduce environmentally hazardous substances and prevent environmental accidents and occupational accidents and injuries in all business activities as one of the 16 key drivers to achieve Vision 2030.

While energy consumption increased along with an increase in our operations in FY2022, we are implementing measures to reduce CO2 emissions, including setting energy conservation targets at each office and plant, making improvements to development and production processes, and installing high-efficiency equipment to achieve energy savings.

Annual Energy Consumption

Reduction of Greenhouse Gas Emission Intensity

We have set a target to achieve a 50% reduction in our greenhouse gas (GHG) emissions intensity by 2030, compared to the 2013 level. GHG emissions are considered to be the cause of global warming, and we are pursuing initiatives to reduce them.

Target to Reduce Greenhouse Gas Emission Intensity

Initiatives for Target Achievement
  • Energy conservation and loss reduction measures for electricity and LNG use (installation of LED lighting and higher-efficiency air conditioning equipment)
  • Adoption of highly energy-efficient equipment and technology
  • Improvement in development and production effciency
  • Adoption and expanded use of renewable energy

Effective Water Use

We have installed our own water supply equipment and are working to minimize water usage by recycling water.

Effective Resource Use

Precious Metal Recycling

Platinum (Pt), palladium (Pd), rhodium (Rh), ruthenium (Ru) and other precious metals can be found in spent catalysts. Since they are important resources, N.E. CHEMCAT has its own facilities for recovery and refining of these metals. High-quality precious metals can be separated, recovered and refined using appropriate technology. This is true even when the post-use precious metal catalyst contains multiple precious metal types, additives, and/or toxic substances that accumulate during use.

Each metal is recovered with a purity of 99.9% or higher purity as shown below.

  • ※Ruthenium is recovered as ruthenium chloride.

Waste Reduction

In order to reduce this waste, we have been enhancing our production processes and updating equipment and machinery.

Management of Chemical Substances

Along with managing chemical substances handled internally, we are promoting chemical substance management for all raw materials and products used in our processes from design to manufacturing and delivery.

Compliance with Chemical Substances Regulations
N.E. CHEMCAT complies with all relevant laws and regulations including Japan's Act on the Regulation of Manufacture and Evaluation of Chemical Substances (Chemical Control Law), Act on the Assessment of Releases of Specified Chemical Substances in the Environment and the Promotion of Management Improvement (Chemical Management Law), and Industrial Safety and Health Act. The appropriate management procedures are stipulated in our Chemical Substance Management Regulations, and chemicals are being properly managed accordingly.
Management of Chemical Substances Contained in Products
In the product design and development stage, we clarify the management standards for chemical substances contained in products to be applied at each stage, from raw material purchase to product manufacturing and delivery.

This allows us to promote appropriate chemical management across the supply chain. In order to manage chemical substances contained in products throughout the supply chain, the key is to appropriately manage chemical substances contained in intermediates and products that are the result of chemical agent conversion.

At N.E. CHEMCAT, we manage not only the amounts of chemical substances found in chemical agents used in intermediates and products, but also the amounts of and changes in chemical substances in the manufacturing process. This extends to the prevention of any contamination.
