Environmental Technology from a Ceramics Town - Unfired Brick Business in Toki-gun, Gifu Prefecture - April 2001

Kamei Seito in Toki-gun, Gifu Prefecture, has developed an environmentally friendly unfired brick called "Arzan Brix. The bricks do not require a firing process, resulting in a low-cost, environmentally friendly manufacturing method. More than 80% of the bricks are made from various waste materials, including incinerated ash from sewage sludge, fly ash from coal-fired power plants, mining waste from glass materials, and residues from mountain soil generated during land development. These materials are kneaded using proprietary technology and molded with a special solidifier to ensure high strength without calcination.

These unfired bricks have excellent water absorbency and are used as paving material for sidewalks and gardens. In particular, they have a significant price advantage, with a retail price of about 90 yen per brick, which is less expensive than existing bricks. This has earned it a high reputation not only for reducing environmental impact, but also for cutting costs. Currently, Kamei Seito is promoting this technology nationwide through a franchise system, and several municipalities and construction companies are already considering the introduction of this technology. Toki-gun is known as a traditional ceramic town, and by utilizing this technology to create new environmental projects, the company is also contributing to the development of sustainable local industry.

Kamei Seito manufactures safe, high-quality unfired eco-bricks using a special solidification technology, aiming to reduce environmental impact. In the production process of unfired eco-bricks, more than 80% of the raw materials are recycled resources, and they are produced under the policy of no firing, no wastewater, and no waste production. Furthermore, in India, research on unfired fly ash bricks is underway to reduce CO2 emissions, and the effects of using a large amount of fly ash on long-term water resistance and compressive strength in the unfired manufacturing process are being studied.
