China: Nanjing Kisen International Engineering has secured a collaboration agreement with Canada-based Delta CleanTech for the implementation of the latter’s carbon capture and storage (CCS) systems at two China National Building Material (CNBM) cement plants. SCMP News has reported that there is a one-time licencing fee - which is not paid by Nanjing Kisen International Engineering but is traditionally paid by the CO₂ capture plant customer - of 4.5 - 5% of capital costs. Installations cost upward of US$40m, depending on capacity.

There are currently 40 operational or upcoming CCS installations nationally with a total capture capacity of 3Mt/yr, chiefly in the oil, coal chemicals and energy sectors.The Chinese Academy of Environmental Planning has forecast that China’s cement industry CCS demand will reach 200Mt/yr by 2060. Delta CleanTech president Jeff Allison said that current challenges for Chinese cement producers seeking to reduce their CO₂ emissions include difficulties disposing of captured CO₂ and a lack of rewards and penalties around emissions control beyond the basic national efficiency requirements.

Nanjing Kisen International Engineering previously launched its first 155kg/day pilot CCS study in partnership with the Canada-based International CCS Knowledge Centre in July 2021.

Mexico: The Mexican Chamber of the Construction Industry (CMIC) has voiced cement price concerns following the introduction of a new environmental tax on mining activity in the state of Nuevo León. Cemex operates a quarry in the state, and has resultingly experienced a rise in the cost of its cement production. The El Norte newspaper has reported that the producer’s Monterrey, Nuevo León, cement plant supplies cement across northeastern Mexico.

CMIC also lobbied the government to begin awarding public works contracts to private investors instead of the Mexican armed forces. It argued that this would help to generate jobs.

Mexico: GCC has signed an engineering, procurement and construction (EPC) contract with ThyssenKrupp Polysius for an upgrade to its integrated Samalayuca plant to increase clinker production capacity, raise the usage of alternative fuels and reduce emissions. The project includes the engineering, supply and modification of the preheater, including cyclones, and an extension to the calciner, with the installation of a Prepol SC-S type system to increase the utilisation of alternative fuels. The work also includes fitting a Polytrack type clinker cooler and the installation of a bypass system. The project will begin in 2022 with operations scheduled to start in the second quarter of 2023.

Peru: The Ministry of Labour and Employment Promotion has initiated talks with cement producers, exporters and unions with a view to changing the standard national cement bag weight. The ministry recognised the 42.5kg/bag standard as a historical anachronism and unsafe. The Federation of Civil Construction Workers (FTCCP) has reported lower back injury as the main cause of ‘desertion of construction site.’ Beside the risk of injury, the standard has allegedly contributed to discrimination against older builders, because site managers often consider even those well below the state early retirement age of 55 to beunfit. The union has argued that 25kg bags would reduce the risk of harm to quality of life to 15%, while 15kg bags would entail a risk of just 5%.

Standards authority Produce will now hold a round table with stakeholders to review the possibility of a 41% weight reduction to the international standard of 25kg. Federation of Cement and Ready-Mix Workers of Peru (FETRACEPPE) general secretary Luis Gilvonio said that this will not solve problems overnight: where firms start instructing workers to carry two bags at a time, their net load will have increased. As such, he argued for continued awareness-raising alongside the law change.

Bagged cement accounted for 70% of Peruvian producers’ cement sales in 2021.

Canada: Lafarge Canada is supplying its ECOPact reduced-CO₂ concrete to contractor PCL for its construction of the upcoming Genesee power plant in Alberta.

Lafarge North America president and general manager Prez Skiba said "The original concrete proposed was already a low carbon design, but we knew we could take it further. We brought in further emissions reductions with our ECOPact design, and we were able to reduce embodied CO₂ by an additional 20%. That's 20% over and above the original design, which already offered a 20% reduction. The combined 36% CO₂ reduction is equivalent to the energy used by 70 houses in a year."
