Colombia: Cemex Colombia has recorded accumulated sales of 500,000m3 of its Vertua reduced-CO₂ concrete. It aims to achieve net zero CO₂ emissions by 2050.

President Alejandro Ramírez said “Our Vertua concrete sales volume is excellent news for the country. It demonstrates that a sustainable vision of construction is being consolidated in Colombia, conscious of its decisive contribution to global climate action.”

Saudi Arabia: Qanbar Ready Mix has run its first trial mix of concrete using Canada-based CarbonCure’s CO2 utilisation technology. The Eastern Province-based ready-mixed concrete producer conducted a full-scale plant trial in late December 2021 in Ras Al Khair Industrial City, according to Gulf Construction. Employees, customers from Saudi Aramco and engineers were present at the event. Concrete supplied from Qanbar Ready Mix’s batching plants will be used to supply projects at the King Salman International Complex for Maritime Industries and Services.

Mexico: Holcim Mexico has replaced 11% of its concrete truck fleet with 61 new natural gas and Euro V diesel-fuelled Sinotruk vehicles worth US$6.2m. The company says that some of the trucks run on 100% natural gas, reducing both their CO₂ and particulate emissions by 25%. Parent company Holcim hopes eventually to roll out Sinotruk vehicles throughout operations in its Latin American region. Each truck has an 8m3-greater capacity than Holcim Mexico’s previous models, and also generates less noise.

Spain: Cemex’s Mósteles clinker pilot batch production unit at IMDEA Energy Institute in Madrid Autonomous Community has produced its first batch of solar-heated clinker. The unit uses Switzerland-based Synhelion solar radiation technology. The technology uses a solar receiver and gaseous heat transfer fluid to heat raw materials.

Cemex chief executive officer Fernando Gonzalez said “The production of the first solar clinker is an exciting milestone for this transformational technology. It is proof of our commitment to deliver tangible outcomes through innovation to achieve our goal of delivering only net-zero CO₂ concrete by 2050.” He concluded “Cemex is building a better future, and that future must be sustainable.”

India: Dalmia Cement (Bharat) has commissioned a 14.7MW solar power plant at its 1.3Mt/yr Kapilas grinding plant in Odisha. The producer says that the new power plant multiplies its total solar power capacity in Cuttack District by six to 17.1MW from 2.4MW.

The company said "Furthering Dalmia Cement (Bharat)'s sustainability goal of becoming carbon negative by 2040, this initiative will enhance the plant's energy efficiencies."

Japan: Sumitomo Osaka Cement started using an internal carbon pricing system for capital investments from January 2022. It is intended to create economic incentives for emission reductions and promote low-carbon investment. The starting price will be around Euro39/t of CO₂. The measure follows the company’s introduction of its 2050 carbon neutral goals and policies in late 2020.

Italy: Holcim has signed a collaboration agreement with energy company Eni for the development of ENI’s magnesium silicate-based carbon utilisation technology. The reaction of the magnesium silicate with captured CO₂ emissions yields a product which Holcim hopes to use in its cement production.

Holcim Innovation Center head Edelio Bermejo said “Reaching net zero in cement manufacturing will require the deployment of carbon capture, utilisation and storage technologies at scale. ENI’s solution is very promising, and we are happy to explore its potential as it could take us all one step further on our decarbonisation journey.”

UK: Cemex UK has launched ReadyBlock Zero, a zero carbon concrete block, on the UK market. The product joins the company’s Vertua reduced-CO₂ product range. Cemex UK achieved zero carbon production by means of offsetting. It said that ReadyBlock Zero will help builders to meet the UK’s government’s Future Homes Standard, which requires a 75 – 80% CO₂ emissions reduction in all newly built homes.

Cemex’s Europe regional urbanisation solutions director of asphalt, paving and building products Carl Platt said “We have developed the UK’s first carbon neutral concrete block to help housebuilders get ahead of the game when it comes to building low carbon homes that meet and exceed government guidelines and changes to building regulations. We want to make life easier for housebuilders to make simple sustainable choices that make large scale impacts on the often complex road to net zero. Concrete blocks are the most common structural component in the construction of UK homes, so by switching to zero carbon blocks, ReadyBlock Zero presents a huge opportunity for housebuilders to make significant carbon reductions.”

Germany: Master Builders Solutions has announced the addition of a new range of admixtures consisting of MasterEase and Master X-Seed to its admixtures portfolio. The company developed MasterEase and Master X-Seed to best enable European cement companies to produce cement of the EU’s new CEM II/C-M and CEM VI Portland-composite cements. Master Builders Solutions hopes that the new products will drive the construction industry’s transition to low-clinker cements and CO2-optimised concrete.

Parent company MBCC Group’s European president Christian Geierhaas said “Providing sustainable solutions is a key factor of Master Builders Solutions’ portfolio and overall strategy. Strong partnerships are essential and support and accelerate the development of significant innovations. We work with major players to continuously develop efficient admixtures to add value to our customers and achieve a long-term sustainable positive effect on the construction industry.” He added “In addition to the usual performance criteria, such as fluidity and compressive strength, our new solutions for our ready-mix customers are characterised by their outstanding robustness. Our admixtures provide an important differentiator by guaranteeing consistently high quality concrete, even upon variation of the cement type and fluctuation of the raw materials used to produce these new, more sustainable cements.”

Turkey: OYAK Cement says that it eliminated 200,000t of CO₂ emissions during 2021 through its use of US-based DataRobot’s AI software. The producer said that the technology enabled it to multiply its alternative fuel (AF) substitution rate by seven an reduce its mechanical failure prediction time by 75%. It added that the software contributed to a US$39m/yr drop in costs.
