Innovating with Metacol™: Mizuiro's New Sustainable Products

Mizuiro Corporation, headquartered in Chuo-ku, Tokyo and led by CEO Naoko Kimura, has reached an exciting milestone in sustainable product development. The company is pleased to announce the release of new products utilizing Metacol™, a revolutionary eco-friendly material made from CO₂ and easily accessible metals, marking a new chapter in their commitment to sustainability.

Mizuiro aims to redefine societal standards through innovative products and experiences, reincarnating materials to unlock new possibilities. The introduction of Metacol™ is part of their vision to encourage upcycled creations, aligning perfectly with their mission. This groundbreaking material has been commercialized through the development of a special paper product called “Washi,” which incorporates Metacol™ components.

What is Metacol™?

Metacol™ is a cutting-edge ceramic material produced from carbon dioxide and common metals. It promotes upcycling by being mixed with recycled plastics, leading to the development of new products. As a natural mineral with low environmental impact, Metacol™ stands out as a sustainable alternative. By effectively utilizing this material, Mizuiro contributes to a carbon-negative future, moving beyond merely achieving carbon neutrality in creating a decarbonized society.

The initial product lineup using Metacol™ includes four distinct items: Metacol™ Hats, Envelopes, Gift Bags, and Gift Boxes. The Metacol™ hats have been designed specifically for workshops at events, allowing participants to draw using Mizuiro's signature Oyasai Crayons® before assembling their own hats. This design not only serves as a fun activity but also demonstrates one of Metacol™'s unique features: its ability to provide shade thanks to its light-blocking properties.

The detailed development of Washi, which blends discarded fruits, vegetables, and flowers with recycled paper, exemplifies Mizuiro’s dedication to innovation and sustainability. This project aims to create a circular economy of upcycled papers, promoting a vision of varied products that will continuously emerge from this initiative.

Mizuiro is committed to the ongoing development of new products leveraging Metacol™.
