China: Huaxin Cement emitted 1.4Mt of CO₂ equivalent in 2018. About 60% of this came from process emissions from making clinker and about 30% came from burning fossil fuels. Additional emissions arose from electrical consumption.

The cement producer says that it implemented a variety of emission control and sustainability initiatives in 2018. These included improving its energy saving management, rollout of waste-heat recovery systems and other plant upgrades. It is also promoting so-called ‘green’ products. In January 2019 its Huaxin Fortune brand 42.5R grade Ordinary Portland Cement obtained low carbon product certification from the China Quality Certification Center.

South Africa: Sephaku Cement estimates it will have to pay up to US$2.8m/yr as part of South Africa’s new carbon tax. The new tax started in June 2019. The subsidiary of Nigeria’s Dangote Cement said that it would apply the tax on its products based on the proportion of clinker per tonne. This would work out at between a 1.5% and 2.5% price increases on lower strength and high strength cement respectively.

In a financial report to 31 March 2019 the cement producer said that its cement sales volumes fell by 6.4% year-on-year due to low cement demand was exacerbated by increases in value added tax (VAT) and fuel prices during the first and last quarter of its financial year. Its sales revenue fell by 3.1% to US$162m and its net profit rose to US$9.08m but only due to a tax credit.

Saudi Arabia: Denmark’s FLSmidth has revealed that it is working on a project to convert a grey cement production line at Alsafwa Cement to a dual-white and grey line. The modified kiln is expected to be commissioned in early 2020. The production objectives are to produce a minimum of 2000t/day white clinker with a maximum heat consumption of 1380kcal/kg clinker. No value for the project has been disclosed.

FLSmidth plans to install its Duoflex Burner inside the kiln. To minimise costs it says that only minor changes will be made to the current preheater with as much existing equipment as possible being reused. In this case, the oil handling equipment, clinker cooler, raw material storage system and raw mill grinding equipment will be reused.

Colombia: Cemex Colombia has been accused by the news division of Caracol Televisión of allegedly making payments to the Juan Manuel Santos presidential campaign in 2014 in return for preferential treatment on construction contracts. Santos subsequently won the 2014 presidential election and served until 2018.

Sources, quoted by Noticias Caracol from a US police investigation into the company, say that it paid US$1m in cash and contributed cement to local candidates. They say that the local candidates then sold the donated cement at a discount for additional campaign funds. The Office of the Attorney General of Colombia is also investigating the matter. The report by Noticias Caracol follows an expose by Semana magazine.

US: ABB has launched its Dodge Safety Mount spherical roller bearings product with a built-in patented locking mechanism. It says that this new feature can reduce installation time by up to 75% compared to traditional products. It is mounted by tightening fasteners, instead of using a hammer and other tools. The new system also allows for simple installation and removal from the same side of the bearing. The new bearing is intended for bulk material and air handling applications.

Safety Mount bearings feature a triple-lip contact seal and corrosion-resistant flinger sealing system, which prevents contamination from entering the product during installation and operation. A labyrinth seal option is available for high-speed and high-temperature applications. The product can also be used with ABB Ability Smart Sensor.
