Germany: Holcim Deutschland, part of Switzerland-based LafargeHolcim, has launched its new ECOPlanet Zero carbon neutral cement. The producer says that it will offset the product’s CO₂ emissions through a peatland rewetting service provided by MoorFutures. The cement also has a low clinker factor due to the use of ground granulated blast furnace slag (GGBFS)-enriched binders.

Cement and binders sales director Matthias von der Brelje said “Holcim has been reducing the specific CO₂ emissions of binders very effectively for decades by using high-quality GGBFS.” He added, “In the future, we want to work with planners, contracting agencies and users to further advance the use of our CO₂-reduced binders. This helps our customers to realise their vision of sustainable building even better. In terms of product technology, the ECOPlanet series also has outstanding - and in some cases even better - properties than Portland cements, for example good workability, light colour, favourable heat development and high fatigue strength.”

Mexico: Holcim Mexico, part of Switzerland-based LafargeHolcim, has launched the new EcoEtiquetas label. The label designates products conforming to a set of ecological criteria set by the company. These include a certain level of recycled content or a reduced carbon footprint, as specified by the label on each product. The label is now found on Holcim Apasco, Maestro and Supra Cemento cement bags. These products say they offer CO₂ reductions from 30 – 60% compared to Ordinary Portland Cement.

Chief executive officer Jaime Hill Tinoco said, “This is one more step on our way to becoming a Net Zero Company, but also when our clients buy our cements with EcoEtiquetas, they will have the certainty that they are collaborating in the care of the environment by using or distributing products that have been thought not only in terms of quality and performance, but also in ensuring a better world for present and future generations.”

UK: The Global Cement and Concrete Association (GCCA) has expanded its Innovandi innovation programme with the addition of a new Open Challenge innovation accelerator programme. The Open Challenge programme will bring together start-ups and leading cement and concrete producers to innovate for CO₂ emissions reduction in the cement industry. Its aim is carbon neutral concrete production by 2050.

GCCA chief executive officer Dinah McLeod said “The GCCA is delighted to be expanding Innovandi to encompass both the Research Network and the upcoming Open Challenge. By connecting innovative start-ups with cement and concrete producers we can help accelerate the development of solutions that address the emissions reduction challenges our industry faces.”

Switzerland: The Solar Impulse Foundation has certified 10 LafargeHolcim products with its ‘Efficient Solutions’ label. The label designates products which protect the environment in a profitable way. The following LafargeHolcim products now bear the label: 14Trees 3D concrete printing technology; Aggneo recycled aggregate; Airium insulating foam; Bio-Active Concrete for coastal ecosystem rehabilitation; Ductal ultra-lightweight concrete; Durabric earth-based block; ECOPact green concrete; TerraFlow low-carbon cement; Kawach water-repellent cement; and the ORIS digital road design platform.

Chief executive officer Jan Jenisch said “I’m very proud of our strong contribution to the Solar Impulse Foundation’s goal of finding 1000 environmentally positive solutions. With more than half of our research and development efforts focused on sustainable building solutions, we are committed to enabling a net-zero future that works for people and the planet. Today’s endorsement of our clean technologies is a great encouragement for our teams to keep on pushing the boundaries of innovation for sustainable building.”

Brazil: Votorantim Cimentos’ consolidated net sales were US$6.41bn in 2020, up by 19% year-on-year from US$5.41bn in 2019. Its adjusted earnings before interest, taxation, depreciation and amortisation (EBITDA) also rose, by 35% to US$1.21bn from US$899m. The group attributed the growth to increased cement volumes sold in Brazil, Canada and the US. Total global cement sales increased by 8% to 32.4Mt. Net revenue grew in all regions, but the sharpest growth was reported in North America at 43% to US$945m.

Chief financial officer Osvaldo Ayres Filho said, “The past year has been extremely challenging due to the pandemic and its impacts across the planet. We have implemented a contingency plan to protect people's lives and preserve operations. This allowed us to respond with agility both in Brazil and in the other markets in which we have operations, ending the year with increased sales, cash generation growth and the lowest leverage in the past ten years.”

During the year, the group unified its joint-venture in Uruguay, with Cementos Molins, at a single site and merged its Canadian and US businesses under a new 83% owned subsidiary. It suspended its Pecém grinding plant expansion in Brazil due to the coronavirus pandemic and resumed it in September 2020. Completion of the project is scheduled for the first half of 2021. The producer also released its Sustainability Commitments for 2030 in November 2020.

India: Ambuja Cement has successfully sent two cement shipments to their destinations using biofuel-powered ships. Two of the company’s cement carriers delivered cement in India while running using biofuel derived from soya extract.

The biodiesel blend (B20) was in compliance with International Maritime Organisation sulphur content requirements and met International Convention for the Safety of Life at Sea (SOLAS) levels in terms of flash point requirements. No increase of NOx was observed with biodiesel blend as compared to low sulphur high-speed diesel (LSHSD), rather the emission level was found to be less. The reduction in CO₂ was found to be around 7% and the total life cycle reduction of CO₂ by life cycle analysis was measured to be around 21%, as the biodiesel from soya extract had a reduction of life cycle greenhouse gas emissions by 70%.

Following the successful initiative, the Directorate General of Shipping has approved biofuels trials for the rest of Ambuja Cement’s fleet, which are mainly deployed on the Indian coastal route.

US: The Portland Cement Association (PCA) has received the 2021 Energy Star Partner of the Year award from the US Environmental Protection Agency and the US Department of Energy. It is the second year in a row the association has been recognised in this way. Each year, the Energy Star program recognises a group of businesses and organisations that have made outstanding contributions to protecting the environment through superior energy achievements.

“The PCA and its members are proud to be recognised for continuously improving energy efficiency to reduce emissions,” said PCA President and chief executive officer Michael Ireland. “The cement and concrete industry is leading the way towards a more sustainable future as PCA and its members are developing an industry roadmap across the entire value chain to reach carbon neutrality by 2050."

In addition to PCA’s Partner of the Year recognition, two PCA member companies, CalPortland and Cemex USA, earned corporate Partner of the Year awards and 13 US cement plants earned Energy Star certification for superior energy performance in 2020.

Japan: Sumitomo Osaka Cement plans to set up a ‘Sustainability Promotion Office’ in April 2021 as part of the company’s efforts towards carbon neutrality by 2050. It follows the company’s medium and long-term sustainability targets that were set in December 2020.

Azerbaijan: Holcim Azerbaijan, part of Switzerland-based LafargeHolcim, has launched its participation in the Azerbaijan Ministry of Ecology and Natural Resources’ National Green Marathon with the planting of 1000 trees at its Garadagh cement plant. Turan Information Agency News has reported that the initiative aims to plant 1 million trees nationally in 2021.

Technical director Ali Huseynov said, "We have a common goal and value - sustainable development. We should apply principles of sustainability in each work and in every step. We are ready to demonstrate our best practices in environmental protection.” He added, “Our work is not over. We should also care for these trees and install an irrigation system. For this purpose, the work necessary for treatment and use of the wastewater in the irrigation system has started, and with this we can save clean water, contributing to the environmental protection."

UK: Tarmac, part of Ireland-based CRH, has relocated reptiles to purpose-built bespoke habitats at its Bellhouse, Essex, quarry. The reptiles lived in an area of planned quarry expansion. Work began in 2016 on the new habitat for grass snakes, common lizards and slow worms, consisting of acid grassland, tussocks and ponds. The company plans to expand the reserve under its site restoration process. It says that this will enable reptile populations to grow.

Restoration manager Enrique Moran Montero said, “The restoration phase of a quarry provides so many opportunities to promote local fauna and flora, and we pride ourselves in making the most of this land. From nature reserves to parks and wildlife learning zones for schools to use, we always strive to provide benefits for local wildlife as well as the communities we work in.”
