Eco-friendly, cherishing our limited resources.
With economic development and material abundance, plastic has become an indispensable part of our lives alongside paper and steel. Today, life without plastic products is unimaginable.
At Nishiki Co., Ltd., we handle everything from plastic raw materials to product manufacturing and recycling.
With our abundant experience and know-how as a total coordinator in the resin business, we will continue to contribute to the sustainable development of the economy and society as a company that plays a role in social development, earning your satisfaction and trust.
BUSINESS
Our divisions collaborate to build a unique 'In-house Circulation System' that circulates resources within the company. The Food Container and Electronic Materials Divisions, which 'create' products, and the Synthetic Resin Division, which 'recycles' them, work together to establish an integrated in-house production system. Through these collaborative efforts across divisions, we aim to achieve sustainable manufacturing that makes effective use of limited resources.

By combining the highly advanced 'recycling technology' we have cultivated over many years with 'compounding' to achieve the color and strength our customers demand, we create high-value-added recycled raw materials that go beyond mere reuse.
