UK: Karbonite UK has developed a new supplementary cementitious material consisting of mineral feedstock, geopolymers and waste biomass. The process also involves CO₂ sequestration and liquid-infused CO₂ absorption within the mineral structure. The material, called Karbonite, is activated at 750 – 850°C, releasing water, which is captured for recycling. Its CO2 emissions are 2.7kg/t, according to Karbonite UK. The developer says that Karbonite ground with 50% clinker yields a cement of equal compressive strength to ordinary Portland cement (OPC).

Karbonite UK is currently preparing a final report on the product for a major cement producer.

Managing director Rajeev Sood said “Karbonite offers a wealth of potential to an industry targeting net zero. We are excited to talk to cement and concrete producers about how they could integrate Karbonite technology into their existing process.”

UK: The World Economic Forum and the Global Cement and Concrete Association (GCCA), in collaboration with Boston Consulting Group (BCG), have released a Mission Possible Partnership Report which identifies the nations that are prioritising green public procurement. These are the Netherlands, Sweden, Germany, France, the UK, and select US states. The report titled ‘Low-Carbon Concrete and Construction - A Review of Green Public Procurement Programmes’ identifies a framework for how these six countries are demonstrating leadership in green public procurement of concrete and construction.

The first component of the framework is the foundation, which includes establishing standards for reporting emissions, databases and tools for tracking emissions and establishes baselines. The second part of the framework, procurement polices, builds upon and reinforces the foundation by setting policies that require environmental disclosures, mandate carbon limits, and incentivise low-carbon design, and use of low-carbon materials.

Approximately 7% of global carbon emissions come from cement, and about half of the cement used globally is procured by the public sector. Governments also spend US$11tn/yr on procurement, about 12% of global gross domestic product (GDP) and regulate the construction industry via building codes. Therefore, governments play a critical role in driving demand to decarbonise the concrete and construction sector to achieve net zero goals.

Matt Rogers, the chief executive officer of the Mission Possible Project said “The demand signals in the market for green industrial products are among the most important opportunities to accelerate the path to net zero across industrial sectors. For material sectors like cement and concrete, government procurement practices will play an especially important role. This report summarises the current best practices in government procurement for green cement across multiple markets. Insights like these provide the government procurement professionals practical tools and technical insights that they can use today to create demand-pull for the most innovative low carbon cement and concrete offerings in the market.”

Turkey: OYAK Cement has detailed its progress towards net zero CO₂ cement production in its Integrated Report 2021. The report's focus is sustainability and digitalisation. Under itsCement 4.0 CO₂ emissions reduction initiative, OYAK Cement has proceeded with efficiency improvements at its cement plants.

OYAK Cement is committed to net zero CO₂ cement production by 2050 and reductions in line with the Paris Agreement to limit global climate change to 1.5°C by 2030.The producer is collaborating withthe Science-Based Targets Initiative (SBTi) to realise its emission reduction goals.

India: The Global Cement & Concrete Association (GCCA) India has released a report entitled ‘Blended Cement – Green, Durable & Sustainable’ to promote the advantages of different types of blended cement over Ordinary Portland Cement (OPC). The report was released by Anil Agrawal, Additional Secretary Department for Promotion of Industry, and Internal Trade (DPIIT), Ministry of Commerce & Industry at an online event hosted by the Indian branch of the Global Cement & Concrete Association (GCCA).

“Blended Cement is the top priority and will play a key role in decarbonising the infrastructure segment. I am happy to see that the global cement and concrete industry has taken the lead, and they have come up with a roadmap. Now the Indian cement sector is developing an India specific detailed roadmap for the cement and concrete industry to achieve the net-zero CO₂ concrete by 2050 in a time-bound manner,” said Agrawal.

The report is a collation of the information about blended cement and its advantages. It highlights the performance improvement possible through this replacement, making blended cement an attractive means to achieve sustainable infrastructure development. It also showcases the benefits of different blended types of cement over OPC based on hydration, microstructure and permeability, rheology and workability, strength development, shrinkage (chemical, autogenous, and drying) and cracks, leaching, alkali-aggregate reactivity, sulphate attack, reinforcement corrosion, long-term durability of construction and usage in preparation of high strength concrete.

Switzerland: Holcim recorded net sales of US$6.75bn in the first quarter of 2022, up by 20% year-on-year from US$5.62bn in the first quarter of 2021. The group’s recurring earnings before interest, taxation, depreciation and amortisation (EBIT) rose by 16% to US$643m from US$553m. The company has upgraded its outlook 2022 to a forecast of full-year net sales growth of at least 10%.

CEO Jan Jenisch said “I am very encouraged by the record start of the year, setting a solid foundation to our Strategy 2025 – Accelerating Green Growth.”

The first quarter of 2022 brought four new bolt-on acquisitions in addition to the group’s conclusion of its US$1.35bn Malarkey Roofing Products acquisition. The company says that it remains actively engaged in supporting humanitarian efforts in Ukraine.

Holcim has also published its industry-first Climate Report 2022. The report details the company’s progress towards achieving its sustainability targets under the four pillars of its Strategy 2025 – Accelerating Green Growth. Under the Accelerating Growth pillar, Holcim reached a total of 15 markets with its ECOPlanet reduced-CO₂ cement range. Under Expanding Solutions & Products, it reduced the proportion of cement sales in its consolidated sales to 57% in 2021 from 60% in 2020. Its other pillars are Leading in Innovation and Sustainability and Delivering Superior Performance. In 2021, the company used 6.6Mt of recycled construction and demolition waste in its products, against a 2050 target of 10Mt.

Chief sustainability and innovation officer Magali Anderson said “On our net-zero journey, we are walking the talk at Holcim, taking clear science-driven action to win the race for climate.”

Switzerland: The latest report from the Intergovernmental Panel on Climate Change (IPCC) has informed policymakers that the best current route to reduce carbon emissions from cement production is through the increased use secondary cementitious materials and by encouraging the development and uptake of carbon capture. Alternatively, the development of new chemistries for building materials could help the situation but this is not expected in the short to medium term.

The report noted that 12Gt of CO₂ equivalent was released directly and indirectly in 2019 from buildings and emissions from cement and steel use for building construction and renovation. These emissions included indirect emissions from offsite generation of electricity and heat, direct emissions produced onsite and emissions from cement and steel used for building construction and renovation. In sections of the IPCC report yet to be finally approved the authors said, “Cement and concrete are currently overused because they are inexpensive, durable, and ubiquitous, and consumption decisions typically do not give weight to their production emissions.”

Overall, the report concluded that average annual global greenhouse gas emissions from 2010 to 2019 were at their highest levels in human history but the rate of growth had slowed. The IPCC has called on “immediate and deep emissions reductions across all sectors” for any chance for society to limit global warming to 1.5°C. To do this global greenhouse gas emissions would have to peak before 2025 at the latest and be reduced by 43% by 2030. However, even if this did occur, it would take until the end of the 21st century for the temperature threshold to be stabilised.

Europe: A forthcoming report by consultancy CemBR has forecast that the European cement industry could potentially face carbon related costs of over Euro1.5bn in 2022 if production continues at 2020 levels or earlier. It looks at the performance of the European cement sector and the impact of the Phase IV of the European Union (EU) Emissions Trading Scheme ( ETS), which started in January 2021. Other key findings include that the sector reduced its carbon emissions per tonne of clinker by a 0.4% compound annual growth rate (CAGR) to the end of Phase III of the scheme.

The commercial market report has analysed the performance of each individual clinker producing plant in the scheme (including the UK) and has compared the end of Phase III with the beginning of Phase IV. It has also detailed the level of free allowances for part one of Phase IV and undertaken several analytical scenarios. Part one, running from 2021 to 2025, of Phase IV allowances for the whole scheme are around 16% lower than the 2020 level. Allowances have remained unchanged for this period but further ‘significant’ reductions are expected for part two of Phase IV. CemBR also reports that not all member countries are in the same position with regard to Phase IV with some countries exposed to more risk. In addition, there is a wide range of vulnerability with regards to carbon among the 201 operational clinker producing plants even within the same market.

The ‘EU ETS & Cement - Enter the Phase IV’ report is due to be published in February 2022.

Zimbabwe: Lafarge Zimbabwe has concluded its assessment of the collapse of its Manresa grinding plant’s roof, which occured in October 2021. The company warned investors that continued disruptions to cement production and the cost of repairs will have a negative impact on its 2022 first-quarter results. It added that normal operations would resume ‘as soon as possible.’

Germany: Holcim Germany has published environmental reports for 2020 focused on each of its cement plants. The subsidiary of Switzerland-based Holcim has decided to target its reports on local issues by issuing separate reports for each of its four integrated plants in the country, at Beckum, Höver, Lägerdorf and Dotternhausen respectively. Each report covers national developments for the sector and the company. Local data is then included as well as data on connected cement grinding and concrete plants. The reports can be downloaded from Holcim Germany’s website.
