Morocco: Holcim subsidiary LafargeHolcim Maroc has released information about its 1.6Mt/yr Agadir cement plant in Souss-Massa Region. The producer invested US$299m in the plant’s construction and it has been operational since late 2021. The plant is highly automated in line with Holcim’s Plants of Tomorrow strategy. It will run off wind power from 2023, and also uses alternative fuel (AF). 200 people work at the plant.

In conjunction with its work in setting up the new cement plant, LafargeHolcim Maroc developed drinking water networks in the surrounding area, including the construction of three solar-powered water towers.

UK: Karbonite UK has developed a new supplementary cementitious material consisting of mineral feedstock, geopolymers and waste biomass. The process also involves CO₂ sequestration and liquid-infused CO₂ absorption within the mineral structure. The material, called Karbonite, is activated at 750 – 850°C, releasing water, which is captured for recycling. Its CO2 emissions are 2.7kg/t, according to Karbonite UK. The developer says that Karbonite ground with 50% clinker yields a cement of equal compressive strength to ordinary Portland cement (OPC).

Karbonite UK is currently preparing a final report on the product for a major cement producer.

Managing director Rajeev Sood said “Karbonite offers a wealth of potential to an industry targeting net zero. We are excited to talk to cement and concrete producers about how they could integrate Karbonite technology into their existing process.”

Nigeria: BUA Cement has donated a solar motorised borehole and medicines worth US$59,600 to eight host communities in Wamakko, Sokoto State. The company says that the efforts are aimed at alleviating the effects of local water scarcity and medicinal supply issues.

Canada: Progressive Planet Solutions has successfully produced a new supplementary cementitious material (SCM) called PozDE from diatomaceous earth. The company says that it developed PozDE using calcium bentonite-containing diatomaceous earth from the Red Lake mine in Kamloops, British Colombia. The SCM’s seven-day and 28-day strength activity index (SAI) values are 101% and 120% those of ordinary Portland cement (OPC) respectively, while its water demand is lower at 98%.

Chief operating officer Ian Grant said “It is uncommon to see SCMs exceed the 7-day strength of the control Portland, so we are excited to see better strength while indicating lower water demand."

India: The National Bank for Agriculture and Rural Development (NABARD) has entrusted Ambuja Cement Foundation with responsibility for a new watershed development project in Himachal Pradesh’s Mandi District. The work will support local farmers in increasing their production and productivity. It will be the 10^th such project that Ambuja Cement Foundation has executed.

Director and CEO Pearl Tiwari said “Ambuja Cement Foundation has a long-standing relationship with NABARD, and we have been working together on watershed development in Himachal Pradesh for the past 14 years. With this new project, we are once again working to empower farmers of another district in the hilly region.”

Nepal: Residents of the Arghakhanchi, Palpa, Pyuthan and Rolpa hill districts of Lumbini Province have reported that increased contamination with residues from limestone extraction has made many traditional water sources unreliable. the Kathmandu Post newspaper has reported that Alpha Cement, BS Cement, Kanchan Quarries, Hongshi Shivam Cement, Palpa Cement, Sarbottam Cement, Satyawati Cement and Siddhartha Minerals operate a total of 10 mines in the affected districts. Springs reportedly took 10 years to recover following the closure of Arghakhanchi Cement’s Narpani quarry in 2012.

Italy: Cementir Holding has been achieved its first CDP A- rating for climate change mitigation in its operations. The producer said that the global average rating is B-, compared to B in Europe and in the cement and concrete industry globally. CDP awarded Cementir a B for water security, its first such rating in the category.

Chair and chief executive officer Francesco Caltagirone said “This achievement is a further recognition of our efforts to make our carbon footprint more sustainable. We are committed to tackling climate change and minimising our environmental impact.”

US: The Portland Cement Association (PCA) has announced the winners of its Energy and Environment Awards 2021. The awards recognise cement plants’ outstanding environmental and social efforts beyond what is required.

CalPortland’s Mojave plant in California won the Energy Efficiency award for an efficiency-increasing upgrade to its vertical roller mill, which included the introduction of a bottom hopper cone on each of its cyclones and a replacement of its mill fan housing. Argos USA’s Calera plant in Alabama won the Land Stewardship award for its conversion an 8.5ha lime kiln dust stockpile into grassland. The area now forms a vibrant ecosystem including wetland habitats. The producer also installed ponds with the additional purpose of stormwater management. Titan America’s Pennsuco plant in Florida won the Overall Environmental Excellence award for its conversion of the plant’s kiln to natural gas from coal use. The upgrade has also enabled the plant to begin to substitute alternative fuel (AF) in the kiln. The Pennsuco plant plans to produce 100% Portland limestone cement (PLC) by ‘as early as 2023.’

Other awards went to Roanoke Cement’s Troutville, Virginia, plant in the Environmental Performance category and to Cemex USA’s Victorville, California, plant in the Outreach category.

PCA President and CEO Michael Ireland said “The US’s cement manufacturers continue to focus on researching and developing new and innovative ways to reduce their environmental footprint. These accomplishments and industry commitment to carbon neutrality across the entire value chain demonstrate PCA members’ dedication to energy efficiency and a more sustainable future.”

India: Ambuja Cements has celebrated the recognition of its water management practices through its listing on CDP's Water A List 2021. The company is the first cement producer to acheive the rating. It said that it succeeded through 'prudent' use of water- for instance through modular curing and concrete mix proportion adjustments - and harvesting. In addition, it continues to evolve its cement portfolio to minimise its consumption of natural resources, with a focus on water. Ambuja Cements' Sustainable Development Ambition 2030 strategy commits it to a freshwater withdrawal reduction of 15% by 2030. Its initiatives have so far saved 70Ml of water, according to the company. It called this a 'robust step' on the global path to sustainable construction and said that it will continue to advocate for environmentally friendly solutions.

Managing director and chief executive officer Neeraj Akhoury said "Water has always been the key focus area for Ambuja Cements. This achievement reaffirms our will to remain committed to address water scarcity issues in future and contribute to the establishment of sustainable tomorrow."

Canada: France-based Fives FCB has secured a contract to upgrade the grinding unit at Ciment Québec’s Saint Basile integrated plant in Quebec. The supplier will install two FCB Horomill grinding workshops with FCB TSV 5000 THF classifiers, FCB aerodecanters and flash dryers and Fives TGT process filters. It said that its mills met the customer’s specifications: namely zero water use; minimum power consumption; data processing; and full automation with rapid recipe change.

Ciments Québec president and chief executive officer Luc Papillon said “After a thorough technical review of the various technologies available today for cement grinding, we have selected the Horomill, being confident that it is the best adapted solution for our multiple cements portfolio and our quest to reduce our cement environmental footprint.”
