In July 2024, following the signing of the grant agreement between the Nitric Acid Climate Action Group (NACAG) Thailand and UBE Chemicals (Asia) Public Company Limited earlier this year to install N2O abatement technology in the caprolactam industry, NACAG Thailand commenced the modification of the basket bottom serving the secondary abatement catalyst operation, and initiated the installation of a monitoring system. This technological installation serves as a mitigation measure in Thailand’s NDC.

After the modification of the equipment at reactor no.1 in preparation for the secondary abatement technology installation during November and December 2024, the project will install a monitoring device to measure the N2O emission baseline following the Quality Assurance Level 1 (QAL1) and Quality Assurance Level 2 (QAL2) standards set by NACAG. Continuous measurement will be carried out for 6 months, starting from June 2025, before installing the catalyst for the secondary abatement technology at reactor no.1 by the end of 2025. Based on its capacity and efficiency, the secondary abatement technology is expected to reduce N₂O emissions by 30,000 tCO₂eq per year.

The Phase 2 operation will subsequently proceed with the installation of the catalyst with reactor no.2 and reactor no.3, in 2027. Once the three reactors are operating at full production capacity and with the efficiency of abatement technology, it is expected that UBE Chemicals (Asia) will be able to reduce N₂O emissions by 100,000 tCO₂eq per year, contributing to Thailand’s national GHG mitigation target in NDC 2030 implemented with international support.
