Titan Cement signs Business Ambition for 1.5°C pledge
14 October 2021Greece: Titan Cement has signed the Science-Based Targets Initiative (SBTi)’s Business Ambition for 1.5°C pledge. In so doing, it joins the UN’s Race to Zero campaign for collaboration towards a global zero-CO2 future. The Group’s decarbonisation plans consist of an increased reliance on alternative fuel (AF), accelerated energy efficiency improvement efforts and a shift to low-carbon products and processes.
Titan Cement said “Through the participation in European and international consortia, as well as through collaborations in research and development projects, Titan will continue to develop low-carbon cementitious products and pilot carbon capture technologies in its plants, actively contributing to the industry’s ambition for a carbon-neutral future.”
US: The Portland Cement Association (PCA) has published a roadmap to carbon neutrality for the cement and concrete sectors by 2050. It says that the strategy document demonstrates how the US cement and concrete industry, along with its entire value chain, can address climate change, decrease greenhouse gases and eliminate barriers that are restricting environmental progress. It added that the document is a ‘major step’ towards engaging US policymakers, industry partners and non-government organisations.
“Cement and concrete have been pivotal in building resilient, durable and sustainable communities that enable people to live safe, productive and healthy lives via structures that withstand natural and man-made disasters,” said PCA President and chief executive officer, Michael Ireland. “The PCA is uniquely positioned to lead the industry-wide ambition to achieving carbon neutrality and enable our member companies and industry partners to continue building a better future.”
The PCA’s roadmap outlines a number of reduction strategies across the various phases of the built environment including production at cement plants, construction including designing and building and everyday infrastructure in use. It also recognises five main areas of opportunity: clinker; cement; concrete; construction; and carbonation (using concrete as a carbon sink).
Notably goals include a reduction of coal and petcoke use at cement plants to 10% in 2050 from 60% at present, a clinker ratio of 75% in 2050 from 90% at present and a reduction of the CO2 intensity of concrete of 60% by 2050. The roadmap also noted the necessity of carbon capture and storage/utilisation (CCUS) for reducing CO2 emissions from cement production. However is pointed out that there are no commercial-scale CCUS installations at any cement plant within the US, location and permitting challenges remained and that infrastructure investment would be required to deal with the captured CO2.

He added "Ambuja Cement will continue to implement such best practices and adopt continuous improvement initiatives to achieve our business vision to be most competitive and sustainable company in our industry.
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.
Forty cement and concrete companies commit to the Global Cement and Concrete Association’s Roadmap to Net Zero
12 October 2021World: 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.”
California legislature enacts cement industry decarbonisation framework for carbon neutrality by 2045
12 October 2021US: 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.
Germany: Scientists at the University of Kassel in Hessen have launched a study into the use of ash from waste incinerators in precast concrete production. The Hessische Allgemeine newspaper has reported that a waste-to-energy plant in Kassel will provide the ash for concrete production in partnership with local companies Kimm Baustoffe and Gebäudeke Baustoff-Recycling. The study aims to produce pre-cast concrete elements containing at least 30% ash, beginning with paving slabs and noise barriers.
Project leader David Laner said that ash has the potential to help lower concrete’s carbon footprint. He said “So far, it has been put to lesser-value uses; we make a product out of it - upcycling instead of downcycling.”
