Travertine Technologies, Inc., has began operations at its demonstration plant in New York state. The core Travertine process demonstrated at this plant combines three major unit operations: salt-splitting electrolysis, caustic direct air capture, and mineralisation. This process produces sulphuric acid, calcium carbonate, and green hydrogen from waste gypsum and carbon dioxide captured directly from the air. The demonstration plant will produce 125 t/a of sulfuric acid, 125 t/a of calcium carbonate, and 55 t/a of carbon dioxide sequestration. The plant will supply sustainable sulphuric acid for local partner Sabin Metal Corporation's precious metals recycling and refining business.

As I write this editorial, the 30th meeting of the Conference of the Parties (COP) to the UN Framework Convention on Climate Change – aka COP-30 – is taking place in Brazil. It is fair to say that the attempt to try to restrict a large greenhouse gas-driven temperature rise across the planet has become one of the defining issues of our age, and particularly for an energy-intensive industry such as our own, responsible as it is for up to 2% of global carbon and carbon equivalent emissions. The move towards lower carbon intensity production of hydrogen, ammonia and methanol, via carbon dioxide capture and sequestration, gasification of biomass or waste, or electrolysis of water using renewable power, has come to dominate our news coverage, and in this issue we also carry articles on the state of play of both ‘blue’ and ‘green’ ammonia production, as well as technology for ‘cracking’ ammonia back to hydrogen and nitrogen for its potential use as a hydrogen carrier.

Travertine Technologies Inc's demonstration plant will produce 125 tonnes per year of sulfuric acid, 125 tonnes per year of calcium carbonate, and 55 tonnes per year of gross carbon dioxide sequestration

Sulphur output in North America continues to decline due to refinery closures and conversions at the same time that acid demand is increasing for metals processing projects.

Gunnison has started producing pure copper cathodes at its Johnson Camp Mine (JCM) in southeast Arizona, United States, from a solvent extraction-electrowinning (SX-EW) circuit and using leaching technology from Rio Tinto-owned Nuton. As well as giving Gunnison exclusive rights to deploy the proprietary process on run-of-mine ore, Nuton is a financial partner of the Phoenix-headquartered mine developer which has restarted copper production at past-producing JCM. The company’s next goal is to ramp-up to nameplate plant capacity of 25 million lbs/year (11,300 t/a) of finished copper.

Linda has signed a new long-term agreement with Blue Point Number One, a joint venture between CF Industries, JERA and Mitsui. Under the terms of the agreement, Linde will supply industrial gases to Blue Point’s 1.4 million t/a low carbon ammonia plant in Ascension Parish, Louisiana. Linde will build, own and operate a world-scale air […]

There has been a release of nitrogen oxides from Austin Powder’s Red Diamond plant in Ohio. The company says that the decomposition of nitric acid caused the incident due to elevated temperatures inside a 5,000-gallon storage tank. This led to a visible release of nitrogen oxide gas, which was vented through the plant’s built-in safety […]

In this CRU Insight, Anthony Rizzo explains why market participants should expect an uneven global demand picture in 2026 and highlights regional variations.

President Donald Trump delayed his ‘liberation day” tariffs by three months on 9th April, while simultaneously ramping up levies on China.

President Donald Trump delayed his ‘liberation day” tariffs by three months on 9th April, while simultaneously ramping up levies on China. In this latest twist to the on-off US tariffs saga, the Trump administration’s 90-day pause on additional duties should provide international suppliers to the world’s biggest fertilizer market with some respite – for now. With the exception of China, the US will now cut back its so-called ‘reciprocal tariffs’ to 10% for the duration of a three-month suspension period. The European Union’s tariff is now halved to 10%, for example, with the trade bloc also pausing its trade countermeasures against the US.
