ALIGNMENT
Nishiki Co., Ltd. has established an internal circular system.
Scrap materials and defective products generated at the plants of the Food Container Division and the Electronic Materials Division are reprocessed into materials by the Synthetic Resin Division and reused as raw materials.
Through this initiative, each employee remains conscious of the effective use of resources as we aim to realize sustainable manufacturing.

SYNTHETIC RESIN
As resin professionals, we add five values to our products: "Quality," "Delivery," "Cost," "Environment," and "Function," considering all of these as integral parts of our service.
By ensuring thorough follow-up from the user's perspective, each employee works diligently to provide our customers with safe and reliable manufacturing.
Furthermore, rather than simple "recycling," we emphasize the perspective of "RE:CYCLE," which is predicated on resource circulation.
We view the entire cycle as a single process—from the upstream stage where waste plastic is generated to the downstream stage where it is converted back into reusable resources.
We collaborate with our customers to consider separation guidelines, defect prevention, and efficient collection and recycling methods when defects occur, advancing our daily research and development to create products that combine environmental friendliness, quality, and functionality.

Resin Division

ELECTRONIC MATERIALS
Scrap materials generated during the manufacturing process are collected directly instead of being discarded, and are reborn into new resources through our unique "Internal Circular Recycling System."
The scrap materials crushed at each plant are processed into new raw materials at our recycling plant, ultimately becoming products that support your daily life once again, such as stationery and agricultural materials.






About the Electronic
Materials Division

FOOD CONTAINER
We strive to create earth-friendly products based on three core initiatives: developing high-quality, reusable products, creating products using environmentally friendly raw materials, and promoting resource-conscious recycling.



Nishiki's containers possess both elegance and artistry, with 99% of our customers feeling it would be "a waste to throw them away" and reusing them at home for other dishes.
* The remaining 1% is recycled through the Nishiki Recycling System as part of our efforts to protect resources.
