The signing ceremony took place on 5 September 2025 at the PCS Thailand headquarters, marking a strategic collaboration that brings together cutting-edge SAO technology and PCS’s professional cleaning expertise. This initiative reflects our ongoing commitment to Environmental, Social, and Governance (ESG) principles.
