At Narumi, sustainable manufacturing means pairing craft with innovation. Their latest initiative turns eggshells into a valuable raw material.
Eggs and bone china share a common element: calcium.
Narumi Bone China uses over 40 per cent calcium phosphate (bone ash), while eggshells are composed of over 90 per cent calcium carbonate.
Applying decades of grinding and firing expertise from bone china production, Narumi has turned eggshell byproducts into an upcycled material. Narumi has already began integrating it into the bone china body across their production line, and will gradually increase its share over time.
This shift reduces Narumi’s reliance on conventional resources and supports a new line of business: producing and supplying eggshell-derived calcium powder for use in tableware and beyond.
For generations, Narumi has carried forward the tradition of bone china, a craft born in Britain and refined through Japan’s distinctive artistry and precision. With this step, they move beyond tradition—advancing their environmental initiatives and creating new value that endures. See them at Host to learn more.
