US: The Portland Cement Association (PCA)’s Environment and Energy Committee met in Tampa, Florida, to discuss the formation of a new coalition with other industry bodies under the leadership of the US Chamber of Commerce. The PCA said the coalition will take legal action against the US government, following the Environmental Protection Association (EPA)'s introduction of new, lower particulates emissions standards. The association says that the revised standards may lead to layoffs and lower cement and concrete production.

Other items on the agenda for the committee’s biannual meeting include permitting and regulatory reform for carbon capture, utilisation and storage and alternative fuels for cement production.

Vietnam: The government has launched a public consultation over a proposed environmental protection fee. The Vietnam Investment Review newspaper has reported that the proposed policy would require emitters of dust, NO_x, sulphur oxides and carbon monoxide, including cement plants, to pay a basic fee of US$127/yr. Additional variable rates of US$0.02 – 0.03/t would apply to emissions of each of the pollutants. If it enters into force, the regulation will require cement plants to submit quarterly fee declarations to the government. The government says that the policy aims to encourage investment in emissions mitigation technologies.

UK: Aggregate Industries subsidiary Lafarge Cement has begun installing a new Euro10m bag filter system at its 1Mt/yr Cauldon cement plant in Staffordshire. The project is due for delivery in early 2024. The system consists of 2080 fabric bags to remove particulates from the plant's flue gases. It will replace the plant's existing electrostatic precipitation system. The company says that the system will triple the removal rate of particulates, reducing them to 10mg/Nm³ from 30mg/Nm³.

Cauldon cement plant manager Thierry Davila said “The installation of the new system will help us provide a step change in our efficiency and effectiveness, and optimise kiln performance. The plant and our operations will hugely benefit from up-to-date technology, which will result in more consistent running of the site, but also it will improve environmental performance and benefit the local community. The new filter system will mean less dust and emissions into the atmosphere and a reduction in pollutants, which is hugely positive and in line with our approach to sustainability.”

India: Dalmia Cement (Bharat) has successfully launched its new fleet of 35 liquefied natural gas (LNG)-fuelled trucks from its Murli cement plant in Maharashtra. The trucks are of two types, covering ranges of 50 - 600km, and will transport bagged cement and bulk raw materials. They have 28% lower CO₂ emissions than conventional diesel-powered trucks, and are thus able to eliminate 840t/yr of CO₂ emissions, while also reducing emissions of nitrous oxides (NO_x) by 59% and particulates by 91%, and eliminating emissions of sulphur oxides (SO_x).

Dalmia Cement (Bharat) says that its next move will be to launch a second fleet of 25 trucks from its Ariyalapur cement plant in Tamil Nadu. By April 2024, it plans to convert 10% of its 3000 truck-strong fleet to LNG fuel.

A spokesperson for the company said “Dalmia Cement has been following the business philosophy of Clean & Green is Profitable and Sustainable. Our overall CO₂ emissions have come down from 670kg/t to 467kg/t – one of the lowest globally – and we are focusing on realising our carbon negative goal by 2040. We are delighted to partner with GreenLine Logistics for further reduction of our Scope 3 greenhouse gas emissions.”

UK: Cemex has bought 10 Volvo 460 8x4 tipper trucks for use at its Angerstein Wharf aggregates depot in Greenwich. From there, the trucks will deliver sand and aggregates all around London. The trucks’ bodies are made of lightweight aluminium, and they conform to Euro 6 emissions standards. This corresponds to 80% NO_x emissions reduction and 50% particulate emissions reduction compared to Euro 5 standards.

Cemex UK fleet engineering manager Nigel Ponton said “The addition of these new trucks to our fleet will enable us to better meet customer demand, safely and efficiently. Safety is the number one focus whenever we add new trucks to our operation and these Volvos tick every box in that respect.” Ponton continued “These trucks will all be working in busy streets across London so it’s imperative we provide our drivers with the best tools possible to do the job and help protect any vulnerable road users. Moreover, thanks to the improved fuel efficiencies and enhanced payload these new Volvos are the most sustainable vehicles we’ve ever had and will help decarbonise our delivery footprint.”

Pakistan: The Pakistan National Forum of Environment and Health (NFEH) has recognised Lucky Cement’s sustainability successes with a prize at the 19th Annual Environment Excellence Awards 2022. The company’s comprehensive environmental management and monitoring plan covers its solid waste, noise pollution and emissions, including particulates. It says that this is essential to preserving the ecosystem in which it operates.

Chief operating officer Amin Ganny said “We believe in environment-friendly practices and are committed to conserving the environment. Implementation of sustainability into our core business operations has always been one of our main objectives.”

US: Italy-based Buzzi Unicem subsidiary Lone Star Industries has concluded a settlement with the US Department of Justice, the Environmental Protection Agency and the state of Indiana over Clean Air Act violations at its integrated Greencastle plant in Indiana, dating from 2010 to the present day. The Indy Star newspaper has reported that under the terms of the settlement the producer must pay a fine of US$700,000. The authorities ordered the company to upgrade the plant in line with state and federal pollution regulations. The violations involved emissions of particulate matter that exceeded state and federal limits.

US: Dragon Products has been fined US$67,000 by the Maine Department of Environmental Protection for exceeding air emissions regulations since 2013. Ammonia, carbon monoxide and particulate matter levels were all breeched, according to the Bangor Daily News newspaper. Other irregularities with standards were also noted, such as baghouse inlet temperature limits and clinker cooler opacity standards.

China: China Tianrui Group has reported gross CO₂ emissions per tonne of cement of 910kg/t in 2019 in its latest sustainability report. Nitrogen oxide and particulate matter emissions were 7862t and 1380t, year-on-year decreases of 13% and 4% respectively. Its water consumption intensity decreased by 42% year-on-year to 1.12Mm3.

The group operates 20 clinker production lines and 59 cement grinding production lines. Its production capacity of clinker and cement was 28.4Mt tonnes and 56.7Mt respectively in 2019. Its plants are based in Henan, Liaoning, Anhui and Tianjin, with Henan and Liaoning accounting for the largest proportion.

Uzbekistan: The State Committee of Uzbekistan for Ecology and Environmental Protection plans to create a system of monitoring stations for automatic measurement of air pollution, including particulate matter (PM), throughout the country. Part of this will include the installation of automatic emissions sampling and analysis stations at a number of industrial plants, as well as static monitoring stations within and near plant sites, including in the cement sector. Installation will be at the cost of the industrial facility.

In late 2019 the State Committee for Ecology, together with the Ministry of Health and Uzhydromet, took samples of air from 13 cement plants, finding that five greatly exceeded international norms for dust emissions. Based on the results of the audit, the committee has developed a draft government decree on strengthening environmental control over cement plants. If the document is approved, then all existing cement manufacturers will be obliged to install automatic sampling stations for analysis of air pollution by 1 January 2022, as well as stationary posts in the adjacent territory at their own expense.
