China: China plans to expand its national carbon trading market to encompass the cement industry by the end of 2024, Bloomberg reports. This initiative, announced by Minister of Ecology and Environment Huang Runqiu, aims to reduce emissions in high-pollution sectors and prepare for the EU’s impending carbon border adjustment mechanism (CBAM) starting in 2026. Currently limited to 2200 power utilities, the expansion will integrate seven more sectors into the market, which China hopes will cover 70% of its emissions by 2030. The Ministry is reportedly seeking public feedback on the proposal until 19 September 2024.

Canada: Ash Grove Mississauga cement plant has entered a proposal with the Ministry of Environment Conservation and Parks to burn alternative fuels. This includes materials such as construction and demolition materials, paper fibre, wood, plastic and industrial rubber, according to the Insauga newspaper. Local residents have expressed concerns about potential toxicity and environmental impacts due to emissions from the plant entering the atmosphere. The association reportedly objected to a previous application allowing higher emissions levels at the plant. Ash Grove will address these concerns in a public meeting scheduled for 12 September 2024.

Vietnam: Fico Tay Ninh Cement has launched ‘green-labelled’ cement with CO₂ emissions between 350-600kg/t, 70% lower than traditional Portland cement, according to Tuoi Tre News. Director of Fico Tay Ninh Cement, Nguyen Cong Bao, said that the company has invested in automated production lines and research and development to produce this ‘eco-friendly’ cement, aiming to offer it at competitive prices due to cost-saving technologies.

In addition, SCG Concrete Roof Company has introduced its own ‘green’ cement to the local market, reducing carbon emissions by 20% during production compared to traditional Portland cement.

Vietnam: Vietnam's cement sector anticipates minimal impact from the EU's carbon border adjustment mechanism (CBAM) as exports to the EU account for less than 2% of total sales, according to the Vietnam News Brief Service. However, Luong Duc Long, vice president and general secretary of the Vietnam Cement Association, remains alert to potential changes in emission thresholds that could incur additional taxes. Currently, the country’s cement sector emits 700 - 750kg/t of CO₂, with goals to reduce this to 650kg/t by 2030 and to 550kg/t by 2050 through technological advancements like rotary kilns and AI, as well as the use of alternative fuels and waste management solutions.

Nigeria: Lafarge Africa has launched ECOPlanet Unicem, the country's first low-carbon multipurpose cement, from its Mfamosing plant in Cross River State. The new product is reportedly designed with over 30% reduction in CO₂ emissions. ECOPlanet will be available nationwide by the end of 2024.

Cameroon: Cimpor has inaugurated its new plant in Kribi, Cameroon. Following investments in Côte d'Ivoire, Cimpor embarked on this greenfield project in February 2020, integrating the ‘world's first’ operational flash calcined clay production line, launched on 29 October 2023.

Cimpor Cameroun now has an output of 1.2Mt/yr of cement and 0.4Mt/yr of calcined clay. Cimpor's calcined clay production technology - ‘deOHclay’ – reportedly saves up to 80% in CO₂ emissions, up to 35% in electricity consumption and up to 40% in thermal energy consumption per tonne. Compared to a plant with a similar capacity, this technology could reduce CO₂ emissions by around 0.2Mt/yr, according to the company. The new plant will reduce the country’s dependence on imports to meet local cement needs.

Philippines: Taiheiyo Cement Philippines has inaugurated a new US$220m production line at its plant in San Fernando, Cebu, which is expected to support national cement production and reduce reliance on imports. The plant now has a capacity of 3Mt/yr, or 6000t/day of clinker. The new production line replaced the old facility, which was demolished in 2021. The facility incorporates kiln renewal technology that reportedly cuts CO₂ emissions by at least 10% through reduced energy consumption and a lower clinker factor. San Fernando Mayor Mytha Ann Canoy said the new facility is expected to generate 2000 new jobs.

US: Heidelberg Materials has won negotiation for up to US$5m in funding from the US Environmental Protection Agency (EPA) to develop a web-based tool for cement facilities to produce Environmental Product Declarations (EPD). The funding is part of the EPA’s grant initiative to report and reduce emissions from the manufacture of construction materials, which awarded nearly US$160m to 38 recipients nationally.

Canada: Minister of Environment and Climate Change, Steven Guilbeault, announced the reinvestment of up to US$1.6m from industrial pollution pricing proceeds into a new emissions reduction project at St Marys Cement in St Marys, Ontario. This initiative will involve the installation of a new kiln utilising low-carbon fuels, including discarded plastics, to reduce the use of carbon-intensive fuels used in the manufacturing process by up to 30%. The project aims for a reduction of over 39,900t of greenhouse gas emissions by 2030, according to Foreign Affairs news.

South Korea: South Korean cement manufacturers recently convened at an event hosted by the Korea Cement Association and the Korea Industry Alliance Forum to discuss how to achieve carbon neutrality. The industry currently faces financial challenges in upgrading equipment due to low cement prices. However, it has achieved a 20% decrease in greenhouse gas emissions per tonne of cement since 2014, aided by the use of alternative fuels and investment in energy efficiency. The Korean government now requires that greenhouse gases be cut by 12% by 2023 from 2018 levels by 53% by 2050.

The industry currently uses post-consumer plastics as fuels instead of fossil fuels and incorporates byproducts from other industries, like sludge. However, some environmental groups have labelled cement made from industrial byproducts as ‘garbage cement’ claiming it contains hexavalent chromium levels more than four times the EU’s allowable limits. The use of plastics as alternative fuel has also sparked complaints from local waste collection and incineration companies, who argue that cement companies are taking away their business.

Professor Kim Jin-man from Kongju National University said "We also need to focus on developing high-performance clinker, advanced chemical admixtures for concrete, and accelerators that shorten concrete curing times."
