India: Researchers at the Visvesvaraya National Institute of Technology in Nagpur, Maharashtra, have shown in laboratory studies that an enzyme called urease found in watermelon seeds can strengthen cementitious materials and repair cracks in concrete. The Times of India newspaper has reported that the study found around a 22% increase in compressive strength, a 19% reduction in water absorption and improvements in durability. It is hoped that the food industry waste product could potentially be used to replace chemical admixtures commonly used in concrete production. Field studies are now set to follow.

Study leader associate professor Madhuwanti Latkar said, “Watermelon seeds are magic beans when it comes to importing strength to cementitious materials.”

Brazil: Votorantim Cimentos is preparing to bid for some of LafargeHolcim’s assets in Brazil. However, the company is limited by local competition rules so it is unable to try and buy all of LafargeHolcim’s assets, according the Valor Economico newspaper. In a statement to Reuters, Votorantim said that it had not made a bid yet but that it was always open to new opportunities. LafargeHolcim was reported by local press in April 2021 as wanting to sell its assets in the country.

Uruguay: The Administación Nacional de Combustibles, Alcohol y Portland (ANCAP) and the Administración de Ferrocarriles del Estado (AFE) have signed an agreement to exchange logistics services, materials and real estate. Under the deal ANCAP estimates that 380,000tt/yr of fuel and 390,000t/yr of cement and limestone can be transported by rail. The arrangement also includes: offering preferential transport rates to ANCAP; moving cement and limestone between ANCAP’s plants and quarries; conducting restorative work at ANCAP’s Queguay limestone quarry and its integrated Paysandú cement plant; and supplying rail ballast to AFE.

Philippines: Holcim Philippines says it is focusing on sustainability and invocation to its customers. At a virtual conference held in mid-June 2021, the building materials producer said that it is using more alternative low-carbon fuels and developing new products that contain less clinker. It added that builders could improve their carbon footprint by ensuring that structures are made with the right materials to meet strength and durability requirements without being overdesigned and that hardware stores could play a role in guiding customers to the correct building materials for their projects. The company is also working on its digital platforms to make customer transactions smoother.

“With our commitment to sustainability and innovation, we will develop the next generation of building materials that will help the country build better for the future. We want to continue to strengthen our collaboration with our customers to raise consumer awareness that these products support their aspirations for a greener and healthier Philippines," said Horia Adrian, Holcim Philippines’ president and chief executive officer.

Cyprus: Eureka Shipping has ordered two cement carriers from Netherlands-based shipbuilder Royal Bodewes. This latest order represents the fourth and fifth ships in a series that Eureka Shipping, a joint venture between SMT Cement Ships and the CSL Group, has requested from the shipbuilder, according to Maritime Reporter & Engineering News. The new ships follow the Aalborg White, Kongsdal and Norden that were built in 2019. Each vessel has a capacity of 4252dwt. Eureka Shipping operates a fleet of 13 cement carriers with a range of 3000 – 23,000dwt.

New Zealand: Stevenson Concrete is set to bring concrete made using CarbonCure technology to the country in July 2021. The Auckland-based concrete producer is currently conducting final internal quality assurance at its Drury quarry and concrete plant before opening the product up on general sale. Canada-based CarbonCure’s technology uses a CO₂ mineralisation process during production to reduce carbon footprint of concrete.

"Along with a number of other carbon-decreasing initiatives we are using, this technology is going to change the way New Zealand builds houses, footpaths, roads, pipes, and thousands of other man-made, everyday objects. Stevenson has brought it into the New Zealand mainstream, just as this technology is used in countries like Singapore, North America and parts of Europe," said Anthony Bitossi, general manager of Stevenson Concrete.

Brazil: Companhia Siderúrgica Nacional (CSN) has agreed to buy Cimento Elizabeth for US$220m from Farallon Capital. The acquisition will give CSN an additional 1.3Mt/yr cement production capacity bringing its total to 6Mt/yr, according to the Valor Econômico newspaper. The deal will also give it a presence in the Northeast, add modern equipment to its assets and ‘substantial’ reserves of limestone, The purchase will be subject to regulatory approval.

India: Wonder Cement has ordered its eighth vertical roller mill from Germany-based Gebr. Pfeiffer. A MPS 3070 BK type mill has been selected for grinding petroleum coke and coal. The throughput rate for pure petcoke grinding will be 40t/hr with a product fineness of 2% R 90µm. The mill will be equipped with an SLS 2900 BK type classifier. Due to the high abrasiveness of Indian coal, the mill and classifier will be designed with a correspondingly robust wear protection. The new mill will support the fourth 8000t/day production line at the producer’s plant at Tehsil Nimbahera, Chittorgarh in Rajasthan.

Most of the components of the coal mill will be manufactured by Gebr. Pfeiffer India including the housing and foundation parts, the grinding bowl and a large part of the force-transmitting parts. Delivery of the mill is scheduled for the end of 2021. Commissioning of the entire kiln line with the new grinding plant is scheduled for spring 2022.

Cameroon: Luc Magloire, the Minister of Commerce, has written to Cimenteries du Cameroun (CIMENCAM) threatening to close its production facilities if it raises its prices without approval. In the letter the minister accused the subsidiary of LafargeHolcim of increasing its wholesale prices and of preparing to do so again without consent, according to the Ecofin Agency. Prices have reportedly risen by up to 8% in some places.

Friction occurred between the government and CIMENCAM in 2020 when LafargeHolcim renewed the term of Benoît Galichet as the chief executive officer of its local subsidiary. The government, a large minority shareholder of the company, opposed the decision. The government and the cement producer have also disagreed previously over the price of cement.

UK: Fitch Ratings says it does not expect the financial profiles of cement producers to be changed by decarbonisation efforts in its rating horizon. The credit rating agency expects that regulatory scrutiny, investor pressure and societal awareness are likely to accelerate the building materials sector’s decarbonisation drive. However, it predicts that producers will pass on costs to consumers as there are no substitutes for its products. In addition, demand for building materials will grow, supported by increasing needs for infrastructure to cope with the transition to a low-carbon economy and the physical effects of climate change.

It added that, since there are no low carbon solution readily available, such improvements will require ‘significant’ investment and research. Fitch Ratings expect this to arrive after 2030 to meet the tight 2050 sustainability targets by both governments and companies. The cost of this may be large especially as government incentives to support it are, as yet, uncertain.

Fitch Ratings noted that the industry had made significant progress with an 18% reduction in the global average CO₂ intensity of cement production since 1990. However, due to growing demand for cement, the sector’s gross emissions have increased by 50%. It pointed out the large role China and India have to play in emissions reductions as they are the largest concrete producers in the world. However, Europe is seen as the most demanding region for decarbonisation regulations at present.
