US: Lehigh Cement and Argos USA have agreed to pay a US$1.5m fine for alleged Clean Air Act violations at the Martinsburg cement plant in West Virginia. Argos has owned the plant since December 2016 and Lehigh Cement was the previous owner. The violations occurred from 2013 to 2016. Neither Lehigh Cement nor Argos USA admitted liability for the alleged violations as part of the settlement.

The Environmental Protection Agency (EPA) cited the companies for various Clean Air Act violations based on responses to EPA information requests and data collected and reported under the plant’s permit. These included exceeding particulate matter emissions, non-compliance with opacity testing, failing to comply with requirements for operating a kiln with dioxin/furan emission limits, failing to perform required stack testing on a kiln’s exhaust in a timely manner and other violations.

US: Illinois State University has been awarded a US$15,000 grant by the Environmental Protection Agency (EPA) to research the use of recycled glass as a substitute for Ordinary Portland Cement and fly ash in controlled low-strength material (CLSM). CLSM, also called flowable fill, is a cement-based construction material commonly used for backfilling trenches or other excavations, as well as soil-stabilisation. It can be produced at any ready-mix concrete plant by mixing cement, fly ash, sand and water in the correct proportions.

Project lead Pranshoo Solanki said that preliminary results are promising, and show that required flow and strength can be met by replacing cement and fly ash with recycled glass powder.

The EPA grant is for phase one of the recycled glass project for research at the laboratory scale. Funding for phase two will then be sought to test the product in real-world trials.

Iran/Afghanistan: Exports of cement from Iran to Afghanistan have increased following the resumption of US-led sanctions on Iran. Speaking on Afghanistan’s Tolo News TV, Janagha Navid, the spokesman of Afghanistan's Chamber of Commerce and Industries, said that Afghanistan imports 80,000t/yr of cement, while stressing that the country’s domestic cement production capacity could increase to 420,000t/yr.

Navid added that cement imports from Pakistan had decreased, while imports from Iran had risen, due to depreciation of the Iranian Rial against foreign currencies. He further highlighted that Afghan customers prefer Iranian cement over Pakistani cement, citing quality considerations. In 2018, Iran exported US$127m-worth of cement to Afghanistan, broadly similar to imports from Pakistan, which came to US$132m.

Colombia: Cemex Colombia has reached a deal with the Attorney General allowing it to operate its Maceo cement plant in Antioquia. Under the terms of the government-brokered agreement Cemex will lease the land from CI Calizas y Minerales for around US$15,000/yr, according to the El Espectador newspaper. The lease has a duration of 21 years and this can be extended by another 10 years.

In 2016 Cemex fired several senior staff members in relation to the Maceo project and its subsidiary’s chief executive resigned. This followed an internal audit and investigation into payments worth around US$20.5m made to a non-governmental third party in connection with the acquisition of the land, mining rights and benefits of the tax free zone for the project. The US Department of Justice is also investigating the project.
