US: A team of researchers at the Massachusetts Institute of Technology (MIT) have demonstrated an electrochemical process to make clinker in a laboratory. A paper on the work by Yet-Ming Chiang, the Kyocera Professor of Materials Science and Engineering at MIT, with postdoctoral researcher Leah Ellis, graduate student Andres Badel and others has been published in the Proceedings of the National Academy of Sciences of the United States of America (PNAS).

In the new process, pulverised limestone is dissolved in acid at one electrode in an electrolyser and carbon dioxide (CO₂) is released in a pure, concentrated stream. Lime is precipitated out as a solid at the other electrode. The lime can then be processed in another step to produce clinker.

Benefits of the new process include potentially substituting fossil fuels with electricity supplied from renewable sources and the production of a pure source of CO₂ that could be captured with less or no scrubbing compared to conventional clinker production.

Saudi Arabia: Najran Cement has received a licence to export clinker from the Saudi Ministry of Commerce and Investment. The licence is valid for a year from 4 September 2019.

Haiti: Jamaica’s Caribbean Cement has begun exporting clinker to Haiti. The Jamaica Observer reports that the first shipment of 7500t of clinker was of surplus material from the company’s 1.3Mt/yr Rockfort Plant. The plant has received US$162m in capital expenditure since 30 June 2015.

Algeria: The value of clinker exports grew to US$30m in the first five months of 2019 from US$3.2m in the same period in 2018. The country is hoping to increase its exports of cement and clinker to around US$500m/yr by the mid-2020s, according to Télévision Algérienne. It is facing a significant production overcapacity with the manufacturing base expected to reach 40.6Mt/yr in 2020. Consumption was 26Mt in 2016.

Sri Lanka: The Sri Lankan Navy has rescued nine sailors from the ‘Sri Lanka Glory,’ a barge that transports clinker to the Rugunu cement grinding plant in Galle. The barge was forced off course by gale-force winds off the coast of Rumassala, according to the Daily Mirror newspaper. A previous attempt to retrieve the seamen from the damaged vessel by tug had failed.

Saudi Arabia: Najran Cement has renewed its clinker export licence. It is valid for one year from 9 July 2019.

Ghana: The Cement Manufacturers Association of Ghana (CMAG) is lobbying the government against a recent fumigation levy of US$0.50/t on imported clinker by the Ministry of Health.
