Ueda Shokai makes all concrete products low-carbon, reducing CO2 emissions by 40%
Concrete products from Ueda Shokai using TUTUMU
Concrete manufacturer Ueda Shokai (Noboribetsu City, Hokkaido) will replace all products it handles with concrete that emits less carbon dioxide (CO2) by the end of 2022. Reduce the amount of cement used as a raw material and reduce CO2 emissions derived from materials by 40%. In the future, we will also promote the development of concrete that emits even less CO2.
Switch to the new concrete "TUTUMU" announced in June. Instead of cement, it uses blast furnace slag, a by-product of steel production, and recycled old concrete as raw materials, reducing CO2 emissions per ton by an average of 41% compared to conventional products. It is said to be stronger and more durable than ordinary concrete.
Ueda Shokai manufactures concrete products used in the construction of tunnels, bridge piers, office buildings, etc., with an annual production volume of approximately 250,000 tons. The goal is to reduce CO2 emissions to virtually zero, including the entire supply chain, by 2045.
Cement, which is used as a concrete material, emits a large amount of CO2 during manufacturing, so there is a movement in the industry to quickly reduce emissions. In July 2010, the emission reduction targets set by Ueda Shokai by 2030 were certified as “Science-Consistent Greenhouse Gas Reduction Targets (SBT)” in line with the Paris Agreement, an international framework.
In Hokkaido, Aizawa Koatsu Concrete (Tomakomai City, Hokkaido), a company in the same industry, launched the "aNET ZERO Initiative," an agreement aimed at achieving virtually zero CO2 emissions as soon as possible. Ueda Shokai also joined in October.
