Japan: Mitsubishi UBE Cement Corporation has started a commercial-scale demonstration test using ammonia as a heat energy source in a cement kiln and calciner at Ube cement plant.

The project, supported by Yamaguchi Prefecture’s 2023 Carbon Neutral Complex Development Promotion Subsidy, follows an ammonia co-combustion test in 2023. In collaboration with UBE Corporation, a test facility for ammonia co-firing was installed.

The company has set a target of replacing 30% of its coal consumption with ammonia in the cement kiln, with similar levels targeted for the calciner by the end of the 2025 financial year. Mitsubishi UBE Cement is also planning further ammonia combustion tests with post-consumer plastics and other materials as energy sources.

India: Swachha Andhra Co. chair K Pattabhiram and Andhra Pradesh Pollution Control Board chair P Krishnaiah said cement manufacturers must use refuse-derived fuel (RDF) in kilns as per the Solid Waste Management rules issued by the Ministry of Housing and Urban Affairs in 2018. The regulation requires a minimum RDF usage of 15% to reduce coal consumption in cement production.

Pattabhiram said 7000t of waste is generated daily from 123 urban local bodies, and stressed the need for daily processing to eliminate dumping yards. He urged cement plants within 400km of municipalities to comply. Krishnaiah added that a joint technical committee would be formed to assist cement producers in implementing the rule.
