US: Heidelberg Materials North America has inaugurated the Port Canaveral slag cement plant and terminal in Florida, following an expansion. MENAFN News has reported that the producer invested US$24m in the installation of a new roller press at the facility.

Heidelberg Materials North America said "Heidelberg Materials' investment in the Port Canaveral slag cement facility is reflective of our commitment to supporting sustainable and resilient construction projects in the state of Florida and throughout the country. It is also aligned with our goal to significantly reduce our carbon footprint by 2030 and another milestone in our overall strategy to grow our portfolio of more sustainable products, technologies and customer-focused solutions on the path to Net Zero."

India: Construction is underway on a section of National Highway 66 in Maharashtra which is being built of concrete made from ground granulated blast furnace slag (GGBFS) and slag cement. India Today News has reported that the Central Road Research Institute developed the technology, in partnership with the National Institute for Transforming India Aayog and the Council of Scientific and Industrial Research.

Australia: Hallett Group plans to establish a slag cement grinding plant in Port Augusta, South Australia. Magnet News has reported the cost of the project as US$83.9m, towards which the producer has received US$13.4m in government funding. The plant will produce cement using South Australian ground granulated blast furnace slag (GGBFS) from Nyrstar’s Port Pirie and Liberty Primary Steel’s Whyalla steel refineries and fly ash from the site of the former Port Augusta power plant. Its operations will be 100% renewably powered. An accompanying new distribution facility at Port Adelaide will ship the cement to markets. The project will create 50 new jobs.

When the Port Augusta grinding plant becomes operational in 2023, its products will reduce regional CO₂ emissions by 300,000t/yr, subsequently rising to 1Mt/yr, according to the company’s expansion plans.

Hallett Group chief executive officer Kane Salisbury said "We're talking about 1% of the entire country's 2030 [CO₂ reduction] commitment, delivered through this project." Salisbury added "We're looking at turning South Australia into a global leader in manufacturing green cement."

Poland: The Building Research Institute has issued environmental product declarations (EPDs) for Cemex Poland’s CEM III slag cement and five other cements produced at its Chełm and Rudniki cement plants and Gdynia grinding plant. The company additionally obtained EPD certification for its Vertua Classic and Vertua Plus concrete products, which contain cement produced using supplementary cementitious materials (SCMs).

Materials director Michał Grys said “For us, product certification is another important step towards sustainable construction and a sustainable future. EPD declarations provide our clients with additional confirmation of the properties of products offered by Cemex Poland. They also improve their chances of obtaining LEED or BREEAM certificates for their investments.”

Philippines: Holcim Philippines has launched ECOPlanet, a slag cement product. It will promote the cement as a general purpose blend for structural applications. It will be made available in 40kg bags in paper and plastic bags. The Philippines will be among the first markets where ECOPlanet is available. The subsidiary of Switzerland-based Holcim also intends to obtain an Environmental Product Declaration (EPD) for the product in the next few months, as well as launching a plastic bag recycling scheme related to the product.

France: Hoffmann Green Cement Technologies has signed a contact with Réunion-based retailer Ravate Group, under which the latter will stock its H-Iona slag cement in its shops in Réunion, Mauritius and Mayotte until 2025.The producer says that the first deliveries will follow in late 2021.

Owners Julien Blanchard and David Hoffmann said “Providing professionals and the general public with the possibility of buying very low-carbon cement, and thus of helping fight global warming, is a source of great pride for Hoffmann. We are delighted to have signed this first H-Iona distribution contract with Ravate Group, an independent family-run business with which we share many values such as innovation and respecting the environment. This partnership will allow us to increase our current order book and generate deliveries of bags of cement from 2021. We intend to sign more partnership deals of this type in order to be able to supply H-IONA and its exceptional benefits, notably environmental benefits, to as many people as possible.”Ravate Group operates over 40 outlets.

UK: Hanson has delivered its 10,000th load of Regen ground granulated blast furnace slag (GGBFS) from its Port Talbotsite in Neath Port Talbot to the building site of the upcoming Hinkley Point C power plant in Somerset. The GGBFS will be used in concrete production there. The latest batch brings the company’s total deliveries to the project to over 230,000t of GGBFS.

Head of nuclear operations Stewart Cameron said “Around 200,000t of CO₂ has been saved in reaching this milestone Regen GGBS load. It is a credit to all those involved as we continue to meet the standards expected of this high-profile project.”

Romania: Liberty Galați said in June 2021 that it exported 50,000t of granulated blast furnace slag (GBFS) to France. The steel company said that a French cement producer will use the GBFS along with clay and gypsum in clinker-free cement production. The alternative cement reduces CO₂ emissions by 80% compared to ordinary Portland cement (OPC), according to the supplier. Liberty Galați’s operations generate 500,000t/yr of GBFS. It says that it has cement industry customers across Europe and Africa.

General Director Aida Nechifor said “Our ambition to become carbon neutral by 2030 involves a new metallurgical route – using direct iron reduction and smelting in electric arc furnaces – increased scrap metal recycling and a transition to domestically-generated green energy. However, we are very happy to be able to ensure that even the by-products of our current production process, such as GBFS, can be used better to help reduce the carbon footprint of other products.”

UK: Hanson’s Regen Ground Granulated Blast furnace Slag (GGBS) product is being used by BAM Nuttall and Network Rail in the first and second phase of building a new sea wall in Dawlish, Devon. So far 4600m³ has been supplied to the project that is intended to protect a railway line from the sea. The bespoke mix being utilised for the project uses Regen GGBS to create a pumpable low carbon concrete that is strong enough to withstand erosion, waves and storm winds while reducing the amount of carbon generated by two-thirds.

“From the earliest phase of this project, we have considered how this scheme can limit its environmental impact without compromising the strength and resilience of the structure. The final design uses piles buried deep in the bedrock to create stability for the structure. Those piles are protected by prefabricated facing panels created off-site and reinforced by concrete poured in behind the visible section of wall,” said Jack Brookes, site agent for BAM Nuttall.

The project has also had to face difficult logistical, technical and operational challenges created by pouring large amounts of high specification concrete up to 200m through the night in very short tidal windows. Hanson plans to supply a further 4500m³ of concrete to the project.

France: Housing developer Ouest Réalisations has awarded a supply contract to Hoffmann Green Cement Technologies. Under the terms of the agreement, the producer will provide the housing developer with its clinker-free low-carbon cement made from blast furnace slag using its H-UKR technology. The order covers a total volume of 75,000m3 of concrete manufactured by concrete plants distributing Hoffmann Green cement, equivalent to 20,000 - 30,000t of cement, for use in Ouest Réalisations’ developments until the end of 2025. These include the 700-unit Batignolles 2025 project in Nantes and the 103-unit La Croix Blanche project in Les Sables d’Olonne.

Hoffmann Green Cement Technologies co-founders Julien Blanchard and David Hoffmann said "This five-year order commitment once again strengthens the value of our carbon-free cement solution. We are very proud to conclude our first partnership with a housing developer, and all the more so with Ouest Réalisations, a Vendée company with whom we share many values and in particular a common vision: that of decarbonising the new housing construction sector. We are looking forward to following Ouest Réalisations’ real-estate programs using our technology."
