NORITAKE CO., LIMITED (Headquarters: Nagoya, Aichi, Representative Director & President: Akira Higashiyama) with the Council of Scientific & Industrial Research – National Institute for Interdisciplinary Science and Technology^*1 (HCSIR-NIIST) , India has jointly developed a CO₂ sorbent for industrial waste gas. This newly developed product captures a high concentration of CO₂ under high-temperature conditions, and Noritake will conduct demonstration tests together with CSIR-NIIST.

Toward achieving carbon neutrality, CO₂ capture technologies are gaining increasing attention. In particular, high-temperature waste gas emitted from industrial facilities such as factories contains a high concentration of CO₂, making efficient capture necessary.

Currently, various methods are being developed and demonstrated, and one of the representative CO₂ capture techniques involves the use of amine solutions with the ability to absorb CO₂. Amine solutions release CO₂ at around 100°C, making them difficult to use in high-temperature conditions. Therefore, when capturing industrial waste gas that often exceeds 300°C, the temperature needs to be lowered before CO₂ capture. This cooling process incurs energy costs. Therefore, there is a demand for materials that can efficiently capture CO₂ at the temperature of the emitted gas.

Noritake, in collaboration with CSIR-NIIST, is planning to conduct demonstration tests of this newly developed product.
