Efforts for Effective Use of Resources

Promoting reductions in waste disposed of in landfills and recycling activities:
* Toward zero emissions

COSEL promotes the Three Rs based on the perspectives of lessening environmental impact and effectible use of resources.
We regularly check the status of waste segregation and strive to raise employees’ awareness.
We will continue our efforts to control the volumes of waste from business activities disposed of in landfills by promoting recycling and thorough waste segregation.

Trends in waste and recycling rates

  • * Zero emissions: Achieving a level of zero waste disposed of in landfills

Examples of initiatives

Reduction

Previously, we had used bubble wrap bags to send certain components to our OEM manufacturers. After unpacking, these were disposed of as industrial waste. We were able to reduce the amount of waste by adopting a new packing method using reusable returnable containers. We also improved the reusability of these containers through means including use of rubber bands to keep their lids in place.

Reuse

Chip components are delivered wound on plastic reels like tape. Previously, we had disposed of the used reels as stable industrial waste.
But since the reels were neither deformed nor soiled after use, we asked the suppliers to collect and reuse them.

Recycling

Defective units that could not be shipped as products and substrate scraps cut off in the production process had been disposed of as industrial waste. Now, we separate them into metals, plastics, and other materials before disposal, so that they can be used to cast ingots or as auxiliary combustion materials in furnaces. We regularly check the status of waste segregation and strive to raise employees' awareness.
