Australia: Research by the Global Carbon Budget (GCB) forecasts that CO₂ emissions will grow by 2.7% year-on-year to a 37.1 ± 2 Gt CO₂ in 2018. This follows a rise of 1.6% to 36.2Gt after a three-year hiatus with stable global emissions. The 2018 forecast is based on preliminary data for the first 6 – 9 months indicate a renewed growth in fossil CO₂ emissions based on national emission projections for China, the US, the European Union (EU) and India and projections of gross domestic product corrected for recent changes in the carbon intensity of the economy for the rest of the world.

In 2017 the GCB estimates that cement sector constituted 4% of global fossil CO₂ emissions, a rise of 1.2% from 2016. Emissions are expected to grow by 4% in China in 2018, in part due to a 1% rise in cement production. In the EU emissions are projected to fall by 0.7% with stable cement sector emissions. In India emissions are forecast to increase by 6.3% with a 13.4% rise in cement sector emissions.

Fossil CO₂ emissions are based on energy statistics and cement production data. The research makes its estimate of emissions from the cement industry using a method adapted from a paper published by Robbie M Andrew of Norway’s CICERO Center for International Climate Research in 2017.

France: Hoffmann Green Cement Technologies has inaugurated its pilot plant at Bournezeau, Vendée. The 50,000t/yr unit will manufacture cement products using metakaolin and blast-furnace slag, according to the L'Usine Nouvelle magazine. It says it will produce cement with reduced CO₂ emissions up to 250kg/t using a flash-calcined process down from 900kg/t in the normal clinker production process. The project had investment of Euro10m.

France: Bénédicte de Bonnechose, the president of the French cement industry union (SFIC), says that country’s cement market is expected to grow by 3% in 2018. She made the comments whilst unveiling local CO₂ reduction targets by 2050, according to the Agence France Presse. The local industry recorded growth of 4% in 2017. She described 2018 as a ‘positive recovery’ with sustained growth following a good first half.

SFIC forecasts that new low-clinker cement products will enter the market by mid-2020. These products include EMC II / CM, EMC VI and LC3 types of cement. These should reduce the CO₂ emissions related to current sold cement products by 35%. Other CO₂ capture initiatives including Oxyfuel, Leiliac and calcium looping cleanker technologies were also mentioned.

Canada: CEMSI, a subsidiary of Kontrol Energy, has received an order worth US$0.8m for an emissions analyser for an unnamed ‘global’ cement company. The product offers on-going regulatory compliance and process data to meet government requirements and reduce fuel and energy costs associated with production. The company said that it has withheld the name of the customer due to ‘industry competitive purposes.’

CEMSI, Is an integrator of turnkey continuous emissions and process monitoring equipment solutions, serving the Canadian and US market. Currently, up to 40% of CEMSI’s revenues are recurring under multi-year service agreements. It was acquired by Kontrol Energy in September 2018.

“This is a significant new order for the CEMSI operating team and adds to a growing vertical line of business in emissions compliance,” said Paul Ghezzi, chief executive officer (CEO) of Kontrol Energy.

Kenya: The Mombasa county government has ordered the closure of a clinker storage plant run by Corrugated Sheets due to the accusation that is has emitted large amounts of dust. Stephen Wambua, the head of the National Environment Management Authority (Nema) in Mombasa said that operations at the Mikindani-based unit had been stopped and would not resume until it was in full compliance with environmental regulations, according to the Business Daily newspaper. The closure followed complaints by local residents.

Wambua said that imported clinker via the Port of Mombasa is stored in a number of premises locally. Dust is emitted during loading and offloading of consignments. Nema is also investigating claims that other companies are storing ‘toxic’ materials in the Jomvu area. In August 2018 the Kenya Star newspaper linked the Corrugated Sheets site to widespread respiratory illness in the local neighbourhood, including some suspected fatalities since clinker storage started in 2010.

India: Mahendra Singhi, the group chief executive officer (CEO) of Dalmia Cement, says that the company aims to be carbon negative by 2040. Singhi made the announcement at the Global Climate Action Summit in San Francisco, US, according to the Indo-Asian News Service. The cement producer is planning to increase its low-carbon product portfolio and use more ‘green’ fuels and raw materials in all of its 14 plants in India.

Dalmia Cement is the first Indian cement company to join RE 100 and it is committed to a target of 100% renewable electricity use. Singhi said that the major challenge is to convert the climate risks into business opportunities while sustaining business growth for the benefit of present as well as future stakeholders. Singhi was previously the Indian co-chair of the Cement Sustainability Initiative (CSI).

Singhi said that Dalmia Group has been able to reduce carbon dioxide emissions to 526kg/t of cement on a group average and to 342kg/t in its eastern operations. According to the CDP (formerly Carbon Disclosure Project) cement sector report in April 2018, Dalmia Bharat achieved the first rank in CDP's low carbon transition league.

UK: The Times has reported on preliminary tests at Lancaster University, Lancashire, UK, which indicate that adding nanoplatelets from carrots and/or sugar beets to concrete significantly enhances its strength.

Including nanoplatelets is reported to increase the concentration of calcium silicate hydrate, leading directly to stronger cement. The researcher reported that, when platelets are added, 40kg less cement is required to make a cubic metre of concrete with the same strength as a sample that does not contain nanoplatelets. This leads to lower CO₂ emissions.

The team added that nanoplatelets performed better than other additives, such as graphene. The concrete made also had a denser microstructure, which helps to prevent corrosion, extending concrete life.

Vietnam: The government of Quang Ngai has threatened to shut the Dai Viet-Dung Quat cement plant if it does not improve its dust emissions. 107 households living within 50m of the unit have been moved but more than 1600 households remain close to the site, according to the Vietnam News Agency. The 0.5Mt/yr cement plant started operation in 2015.

Germany: Two cement plants are installing selective catalytic reduction (SCR) units ahead of new environmental emissions limits that will start in 2019. CRH Opterra Zement’s Karsdorf plant has started a Euro23m upgrade project to its emissions systems. The plant will install SCR units on each of its production lines. Work on the upgrade is scheduled to be completed by the start of 2019.

Holcim WestZement is also installing a SCR unit purchased from Yara at its Beckum cement plant. The Euro14.2m project will start trial operation by the end of 2018.

Ireland: Irish Cement has been fined for dust emissions at its Limerick plant. The subsidiary of CRH was convicted by a local court of breaching its industrial emissions licence in April and May 2017 due to ‘fugitive dust emissions,’ according to the Limerick Leader newspaper. The cement producer pleaded guilty to the charges brought by the Environmental Protection Agency (EPA) and it has been fined Euro1250.

During the court session it was revealed that on one of the days of the dust emissions there were dry conditions with a north-easterly wind that exacerbated the situation. There was also a dust leak as a result of a missing bolt from one of the chutes in a clinker silo as well as a number of infrastructural issues. Irish Cement says it has implemented a number of remedial measures such as replacing the missing bolt and replacing gravel around the site with grass or concrete. It has also conducted a risk-assessment of the whole site. The producer committed a similar offence in 2006.
