North Korea: Manpho cement plant has increased its production capacity by 20% through ‘technical innovations.’ Korean News Service has reported that the installation of new equipment in the plant’s kiln line also improved clinker quality.

India: ACC and Ambuja Cements have partnered with the Indian Institute of Technology Delhi (IITD) to develop a range of calcined clay cements with 50% lower CO₂ emissions than Ordinary Portland Cement (OPC). The collaboration will vary clinker, calcined clay and limestone levels in calcined clay cements in order to ascertain their effects on its performance. France-based Holcim Innovation Centre will fund the research.

Holcim India chief executive officer and managing director Neeraj Akhoury said "Through our extensive research and development setup, we consistently strive to develop new low-CO₂ materials for the construction industry. Calcined clay cement is one such avenue to make a significant quantitative difference in the industry and further accelerate our sustainability drive. Our academic partnership with IITD is a big step towards building a greener future and we are excited to collaborate with the best minds in the country."

The producers have previously partnered with the Indian Institute of Technology Madras (IITM) to study low-CO₂ binders with alternative reinforcements and with the Indian Institute of Technology Hyderabad (IITH) to develop smart sensing technology for continuous on-site strength evaluation of a concrete structure.
