India: The Indian Green Building Council (IGBC) has certified the sustainability claims of Dalmia Cement’s portfolio of blended cements. The portfolio consists of composite cement, Portland pozzolan cement and Portland slag cement. The council employed a full-cycle assessment of the cements’ impacts.

Head of sales, marketing and logstics Sanjay Wali said “We see GreenPro’s accreditation as a milestone in our journey to becoming carbon-negative by 2040. This also reaffirms our blended cement products’ green supremacy, which is accelerating the global transition from a grey to green reality.”

Philippines: Holcim Philippines has announced the launch of its ECOPlanet slag cement. It says the product has a 30% lower carbon footprint than other general purposes products. The company will sell 40kg bags of cement in both paper and plastic bags.

Holcim Philippines president and chief executive officer Horia Adrian said, “Winning with purpose requires delivering our customer promise while also caring for the planet.” He added, “We see a growing interest in building greener structures in the Philippines. ECOPlanet enables us to provide our partners with the best balance of delivering strength and durability while helping make construction more respectful of the environment. It is another key step in our promise to build greener, smarter and for all in the Philippines.”

France: Hoffmann Green Cement Technologies has renewed its strategic partnership with research and testing organization Scientific and Technical Centre for Building (CSTB). CSTB has provided Hoffmann Green Cement Technologies with certification for its clinker-free cements since 2017.It evaluates the products' performance, durability and safety.

The producer said "Hoffmann Green Cement's research and development strategy is to continually invest in the development of new low-carbon technologies. The signing of this partnership agreement will allow the company to benefit over time from optimised deadlines in the processing of its files for the evaluation of its current and future technologies."

Russia: Holcim Russia has committed to realising a 15% CO₂ emissions reduction in its cement production between 2019 and 2030 to 475kg/t from 561kg/t. It plans to further reduce its cement’s CO2 emissions to 453kg/t by 2050, and to implement further measures to ensure its net carbon neutrality at that time.

Corporate relations director Vitaly Bogachenko said “The company's goal is to drastically reduce carbon emissions, and there are two working solutions for this. The first is the use of alternative fuels (AF) obtained from different types of waste: residues of municipal solid waste after sorting and extraction of all useful fractions from them, used tyres and others. The presence of biomass in them makes such fuels carbon neutral, so emissions during production are significantly reduced. The second solution is to replace carbon intensive raw materials. For example, instead of limestone, we use slags. The 'recipe' for cement is completely different: thanks to the new composition and the lower temperature during the firing process, the carbon footprint in the production of cement is reduced.”

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 171,000t of cement to the site of the upcoming Hinkley Point C nuclear power plant in Somerset. It has also delivered 1Mm³ of ready-mix concrete via the customer’s on-site batching plants, 5Mt of aggregates and 443,000t of sand. Its Port Talbot site in Neath Port Talbot has supplied 230,000t of Regen ground granulated blast furnace slag (GGBFS) for use in concrete production, reducing the product’s carbon footprint by a total of 200,000t compared with concrete produced using ordinary Portland cement (OPC) only.

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.”

India: State-owned Visakhapatnam Steel Plant may use available land at its steel plant in Visakhapatnam, Andhra Pradesh to establish a slag cement plant. The Hindu newspaper has reported that the Indian Cabinet Committee on Economic Affairs (CCEA) has decided to privatise the public sector unit. The state government opposes the decision and has proposed a merger with the National Mineral Development Corporation (NMDC) instead. This would integrate Visakhapatnam Steel Plant within the management chain of other resources used in cement production.

Ireland: Ecocem Group has appointed John Reddy as Group Quality and Innovation Application Manager. In the new role he will lead a growing technical team across Europe including Ireland, UK, Sweden, Benelux and France. He is tasked with developing the product pipeline for the group and assisting with product commercialisation across Europe.

Conor O’Riain, Group Managing Director said, “His undeniable commitment to Ecocem and the cement industry is unquestionable and this new role signifies the growth of Ecocem products across Europe. His appointment marks his advocacy to improving the standard of ground granulated blast-furnace slag (GGBS) cement production across the industry”.

Reddy joined Ecocem Ireland in 2004 and has worked for the group in various technical roles. He is a chartered engineer and is a graduate of Civil Engineering from the Dublin Institute of Technology (DIT) and holds an MSc in Advanced Concrete Technology from Queens University, Belfast. His master’s thesis ‘Investigating the thermal activation of GGBS concrete’ was published at the 9th International Concrete Conference and subsequently won the Irish Concrete Society, Sean DeCourcy student award in 2017.

UK: Welding Alloys says that it has carried out maintenance on a vertical roller mill at HeidelbergCement subsidiary Hanson’s 1.0Mt/yr Purfleet slag plant in Essex, repairing the mill’s Loesche 46 2+2S grinding table and rollers. The company said that the mill, which had ground 3500t of granulated blast furnace slag (GBFS), was “in urgent need of refurbishment.” Following a wear audit, Welding Alloys took the grinding components back to the profile template using its Integra Wire Mill products.

The group said that “both companies overcame the challenges of completing the project within the limited shutdown period while complying with the Covid-19 lockdown measures.”
