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.”

China: China National Building Material subsidiary Nanjing Kisen has signed a long-term collaboration agreement with France-based Schneider Electric. The partners plan to develop models for increasing operational efficiency, digitisation and sustainability. Alliance News has reported that they will establish a series of joint pilot projects. They plan subsequently to explore plant engineering, procurement and construction (EPC) opportunities outside of China together.

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."

Switzerland/France: Holcim is collaborating with Engie and and the French National Institute of Applied Sciences (INSA) Lyon to develop a cement-based energy storage technology to serve as an alternative to batteries. The solution will use cement hydration to store heat as energy and release it when needed in an infinitely repeatable cycle. The partners say that it will make energy storage local, safe, affordable and recyclable.

Holcim’s head of global innovation Edelio Bermejo said "The world needs innovative solutions to accelerate our shift towards renewable energy generation, distribution and storage – all areas in which Holcim can play a big part. With this collaboration, we are moving energy storage forward, opening up a new range of solutions based on materials that are local and recyclable."

Colombia: Analyst S&P Global has given Grupo Argos the rank of Gold in its Sustainability Yearbook 2022. Grupo Argos is the only construction materials company to have achieved Gold in the yearbook. Thailand-based Siam Cement Group (SCG) ranked Silver, while Ireland-based CRH and Switzerland-based Holcim, along with the latter’s subsidiary Ambuja Cements, ranked Bronze.

Legal and sustainability vice president María Isabel Echeverri said “This recognition is a result of teamwork and the permanent commitment of Argos to building a better future in which the creation of value for society and for the company is our greatest motivation. We will continue to strengthen our initiatives and strive to positively contribute to the responsible development of our sector and the well-being of our stakeholders, to enable a more sustainable, prosperous and inclusive society.”

UK: Cemex’s corporate venture capital unit Cemex Ventures has invested in gas-to-hydrogen plant producer HiiROC. HiiROC’s thermal plasma electrolysis technology can process biomethane, flare gas and natural gas into hydrogen and carbon black without any CO₂ emissions.

Cemex Ventures president Gonzalo Galindo said “HiiROC's solution is sustainable, scalable, cost-effective and has strong growth potential inside the hydrogen ecosystem. This investment is yet another important step in our transition from fossil to alternative fuels (AF) and towards achieving our Net Zero goal for 2050. Cemex is the clear industry leader in the use of hydrogen, and this partnership allows us to further expand our hydrogen knowledge in the ultimate quest to replace fossil fuels with hydrogen in our plants." He added "With hydrogen becoming an increasingly attractive element for industrial decarbonisation, we are excited to be one of the top companies in the cement industry that includes a clean hydrogen production startup in its investment portfolio."

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.”
