Jamaica: The Ministry of Industry, Investment and Commerce has granted Growth Tech Special Projects a licence to import 50,000t of cement from Turkey before 31 December 2021. The Gleaner newspaper has reported that the nation's other cement importer, Buying House, holds a licence to import 120,000t/yr. Sole producer Caribbean Cement is in the process of expanding its 1Mt/yr Rockfort cement plant's capacity to 1.4Mt/yr.

Finland: The VTT Technical Research Centre of Finland and Finnsementti have revealed work on the Decarbonate project to test a 12m electrically-heated rotary kiln. Other partners on the initiative included Nordkalk and UPM. Precalcination was tested as well as the projection of quick lime. The eventual goal is to use electricity from renewable sources to power the kiln and then capture the CO₂ released for utilisation.

The Decarbonate project has been exploring CO₂ capture and utilisation concepts that can be commercialised. It has run for two years since late 2019 and has funding of Euro1.2m. It has also looked at oxyfuel and electrolysis experiments.

India: Shree Cement has hired FLSmidth to supply a 11,5000t/day kiln line for its planned Nawalgarh, Rajasthan, cement plant. The line will consist of a six-stage preheater and a three-support kiln. The supplier will also deliver an OK vertical roller mill, which it says has a 5 – 10% lower energy consumption than a standard vertical roller mill. The project focuses on sustainable productivity and emissions control. Shree Cement has opted for JetFlex burners to give the lowest possible nitrous oxide emissions for various fuel types.

Shree Cement managing director Prashant Bangur said “Based on the experience of working with FLSmidth on the installation of a 9,000t/day pyro system at the Raipur, Chhattisgarh, cement plant earlier this year, we felt confident about approaching Carsten Riisberg Lund and his team regarding the Rajasthan project.” He added “Being recognised as a Sustainability Champion by the World Economic Forum is a testament of our emphasis on sustainability at every stage of our operations. The new line will push that agenda even further in terms of lowering the benchmarks on energy consumption and emissions, and thereby reducing our environmental footprint.”

FLSmidth also supplied a second OK mill for Shree Cement’s operations in Kolkata, West Bengal.

World: Forty cement and concrete producers, representing 80% of concrete production outside of China in 2020, have together affirmed their commitment to the Global Cement and Concrete Association (GCCA)’s Roadmap to Net Zero concrete decarbonisation strategy. The roadmap’s seven-point plan consists of increased cement plant efficiency, which should eliminate 22% of emissions, increased concrete production efficiency (11%), adjustments to cement and binders (9%), decarbonisation of raw materials (11%), carbon capture and storage (CCS) (36%), a transition to renewable energy (5%) and the natural recarbonation of concrete (6%).

Besides full decarbonisation by 2050, the strategy provides for a 25% reduction in the global concrete sector’s CO₂ emissions by 2030 and the elimination of 4.9Bnt of CO₂ emissions by 2030 alone. The GCCA called the new commitment a ‘significant acceleration’ of cement and concrete producers’ on-going decarbonisation efforts, and said that it represented ‘the biggest global commitment by any industry’ to carbon neutrality. Acknowledging the burden on cement producers, the GCCA called on downstream companies and governments to support the industry’s transition.

GCCA member China National Building Material (CNBM) CEO Cao Jianglin said “This is a landmark for industry co-operation in decarbonisation. As part of a global industry, it will need collaboration across our sector to achieve it. As one of the leading cement and concrete producers in China, we will play our part in decarbonising the industry.”

US: The California State Senate has voted in favour of a bill to implement the US’s most advanced statutory framework for cement industry decarbonisation by 74 votes to two. The statute provides for the implementation of lifecycle CO₂ emissions reporting for cement produced in the state at an estimated cost of US$220,000/yr. The California Air Resources Board will then implement a ‘programme developed as a result of identified strategies’ at an ‘unknown but significant cost.’ The aim of the strategy will be to facilitate a 40% reduction in cement production’s CO₂ emissions between 2019 and 2030 and the attainment of net zero cement production by 2045.
