India: ACC Limited has announced that it will open a 2.5Mt/yr integrated cement plant with ‘state-of-the-art pollution control technology,’ along with a 25MW coal-fired power plant that will serve the plant in addition to an existing 15MW coal-fired power plant on the site in Chandrapur, Maharashtra. The opening in March 2020 will follow the expiry of a period of respite for continued operation of ACC’s 0.9Mt/yr integrated Cement Nagar plant on the same site.
The Times of India has reported that the plant, the company’s oldest, first shut on 30 November 2010 due to repeat violation of pollution standards, and was permitted to reopen in January 2011 up until 28 February 2020, subject to its adherence to strict conditions imposed by the Maharashtra Pollution Control Board (PCB).

Cement exports in the period rose by 11% year-on-year to 1.55Mt from 1.40Mt. 2018’s exports amounted to 0.89Mt (64%) to Uzbekistan, 0.58Mt (41%) to Afghanistan and 0.08Mt (5.8%) to Krygyzstan. Asia-Plus News has reported that tightened pollution legislation in China has driven Chinese-based producers, which accounted for over 90% of Tajik production in 2018, to relocate operations to their country’s western neighbour.
Lehigh Cement and Lehigh White Cement to invest US$12m in pollution control technology
04 December 2019US: Lehigh Cement and Lehigh White Cement have agreed to an investment of US$12m for the installation of pollution control technology across their 11 active cement plants. US Fed News has reported that the upgrades can be expected to reduce net emissions of nitrous oxised (NOx) by 4550t/yr and sulphur dioxide (SO2) by 989t/yr. Lehigh Cement will additionally pay a US$1.3m civil penalty for past Clean Air Act violations.
Uzbekistan: The State Committee for Ecology and Environmental Protection plans to ask cement plants to establish sampling and analysis stations for sources of air pollution by the start of 2022. If they don’t the government will take measures up to and including suspension of production, according to the Trend News Agency. Uzbekistan was ranked in 16th place by AirVisual in a listing of the countries with the most air pollution in 2018.
US: People living near the Cemex Lyons cement plant in Colorado have complained about dust emissions. The Save Our St. Vrain Valley group has filed a report with Boulder County Public Health about dust clouds rising from site, according to the Associated Press.

Conifers indicate cement plant’s carbon footprint
04 September 2019China: Research conducted by the North-West Institute of Eco-Environment and Resources has ascertained detailed data on carbon dioxide (CO2) and mercury (Hg) output at a cement plant in Lanzhou using local spruces.
VerticalNews has reported of distance-dependent variations of Hg concentration in needles close to the cement plant, with the highest concentrations observed in needle samples from the site nearest to the plant. Hg in tree rings increased gradually for all sites by year, reaching a concentration of 65.8ng/g in the last growing period at 0m from the plant.
The study fuels hopes of accurate quantification of historical accumulation of air pollutants, including heavy metals, as well as contributing to our understanding of biochemical Hg cycling in forest ecosystems.
