Future construction with Dioxide Tiles that absorb CO2 from the air

Nihon M-Tecs Co., Ltd. has unveiled a groundbreaking innovation: “Dioxide Tiles.” These interior tiles are crafted using CO2-absorbing materials derived from specially designed vending machines, dubbed “CO2-eating vending machines,” which extract carbon dioxide from the atmosphere.

The Dioxide Tiles boast over 90% of their material from upcycled content. The key ingredients include CO2-absorbed materials and blast furnace slag. The CO2-eating vending machines absorb an amount of CO2 annually equivalent to what 20 mature cedar trees can process.

Approximately 350 machines have been operational across Japan as of November 2024. Installed predominantly in the Kanto and Kansai regions, these machines operate in both indoor and outdoor settings, particularly where CO2 concentrations are high.

Unlike traditional ceramic tiles, which require firing at extreme temperatures of 1,200–1,300 degrees Celsius, Dioxide Tiles are manufactured without firing. Instead, they are produced by compressing and curing mortar, resulting in significantly reduced carbon emissions. Life Cycle Assessment (LCA) data reveal that these tiles achieve carbon-negative status, emitting 103% less CO2 than conventional non-fired tiles. This breakthrough positions Dioxide Tiles as a pioneering solution for reducing emissions in the construction industry.

Nihon M-Tecs and Asahi Soft Drinks Co., Ltd. have jointly filed a patent for the Dioxide Tile technology, with initial applications focused on flooring. Future plans include obtaining fire-resistance certification and developing larger tile sizes, enabling their use as wall materials. The initiative is set to debut commercially next spring, marking the beginning of a new era for sustainable building materials.
