Technologies That Advance Industry While Protecting the Environment

In recent years, plastics have increasingly been seen as harmful to the global environment. At DAIHO, we not only work with petroleum-based plastics but also actively develop products using environmentally friendly materials.
We also operate a proprietary recycling system, enabling us to transform discarded plastic products into new materials. This recycling effort has been ongoing for many years as part of our commitment to sustainability.

Examples of Products

  • ・D-PIM™ (Pulp Injection Molding using 100% natural materials)
  • ・Eco-Recycling System

We recover discarded products, such as refrigerators, and extract only the plastic materials. These are then washed, deodorized, and treated to regenerate them into materials that perform on par with virgin plastic.
