Yara says that it plans to wind down production of phosphate fertilizers and sulphuric acid at two sites in Brazil; Cubatão and Paulínia. The sites are expected to cease production by 3Q 2025, as part of what Yara describes as a strategy to concentrate on more sustainable operations focused on its main activity: the production of nitrogen fertilizers. At Cubatão, the suspension will affect unit 3 and the phosphate plants of unit 2, while units 1 and 2, responsible for the production of nitrogen, in addition to the mixer (unit 5), will continue to operate normally. Yara reported a net loss of $290 million in 4Q 2024, down $536 million from the $246 million profit it made in 4Q 2023. Revenues are down 11% for the year, leading Yara to announce a cost reduction and investment program of $150 million, with the aim of optimising its operations and focusing on strategic areas to ensure long-term sustainability. At the same time, the company has begun renewable ammonia production at Cubatão.

Chile’s environmental regulator SMA has filed a charge against state-owned Codelco, alleging emission violations at its Potrerillos copper smelter in the Atacama region of northern Chile. An audit showed the company had not implemented a monitoring system for sulphur dioxide emissions and other procedures in accordance with environmental standards for the plant, Reuters news agency reported. The SMA labelled the charge as serious, which could lead to a fine of around $4.1 million, and possible revocation of the environmental permit or closure. Codelco had ten days to submit a compliance plan, and 15 days to present a defence.

As more focus extends to a circular economy, there are industry wide discussions on whether future global sulphur demand will be challenged by the energy transition and decarbonisation. Hannes Storch, Collin Bartlett and Marcus Runkel of Metso discuss how the recycling of pyrite tailings could address some of these issues.
