Ube to close ammonia production

Ube Corporation has accelerated closure plans for its nitrogen products in Asia as part of its Vision 2030 plan. The company says that it aims to halt ammonia and related product production at its Ube City plant in Japan by March 2028, two years ahead of its previous schedule. Production of caprolactam and polyamide materials at the same plant will end by March 2027. Post-restructuring, the facility will prioritize specialty chemicals such as polyimides, separation membranes, ceramics, pharmaceuticals, and high-purity chemicals.

In Thailand, Ube will stop producing cyclohexanone, caprolactam, and ammonium sulphate, shutting down one of its two polyamide production lines. The site will shift focus to composite materials, polycarbonate diols, and elastomers, while Ube Fine Chemicals Asia will cease producing 1,6-hexanediol and 1,5-pentanediol.

Mining licence approved for Ammaroo phosphate project

Austrlai’s Northern Territories Government has approved a mining licence for Verdant Minerals’ Ammaroo phosphate project. The approval follows the granting of two mineral leases in March and represents a critical step towards construction and mining operations at one of the world’s largest phosphate resources. Verdant estimates the value of production over the life of the mine to exceed $15 billion. Verdant says that securing the mining licence puts the project firmly on track to reach a final investment decision and commence construction as early as mid-2027. Located 200 kilometres south-east of Tennant Creek, the Ammaroo phosphate deposit contains more than one billion tonnes of phosphate ore.
