Peru: Cemento Gloria subsidiary Cemento Yura's Yura cement plant has allegedly been the source of intermittent dust emissions, water contamination and destructive vibrations during its 50 years of operation. In May 2022, local authorities declared four houses uninhabitable due to cracks in walls and roof collapses. Local people have attributed the damage to the vibrations from the Yura cement plant's activities. In November 2022, local water supply is unavailable for over 40 minutes every day, allegedly also due to the plant's operations.

The La República newspaper has reported that Yura residents have launched a protest against the alleged environmental mismanagement outside of the company's plant.

Saudi Arabia: Yamama Cement has commissioned its second cement plant, with 20,000t/day in capacity across two clinker lines. The producer invested US$1.25bn in the plant's construction, which was carried out by Germany-based ThyssenKrupp. The facility is equipped with seven raw materials crushers, a 3.7km-long limestone conveyor belt, 110,000t of storage capacity, four Quadropol roller mills, two Dopol preheater towers, two Polro rotary kilns, two Polytrack clinker coolers, three 100,000t clinker silos, four Polycom high-pressure roller mills, six 22,590t and 25,000t cement silos and 22,000m³
in water storage basins. The new plant is situated in the eastern Arabian Desert, 80km from Riyadh.

Yamama Cement also operates the 6.4Mt/yr Al Karj Cement plant, 70km from Riyadh.

Germany: Loesche has published its Sustainability Report of its performance in 2021. The supplier’s Scope 1 and 2 CO₂ emissions declined by 6.1% year-on-year to 229t from 244t in 2020 and by 19% over the two years from 2019, when they totalled 282t. It reduced the share of Scope 2 emissions in the figure to 40% from 41% in 2020 and 45% in 2019.

Loesche offers emissions-reducing products to the global cement industry under the label Greenkey Solutions. These include its A/Fuel and H/combust ranges for alternative fuels and green hydrogen upgrades, its C/Clay range for clay calcining and grinding, its Digital/Ready 4.0! range for predictive process optimisation and smart asset management, its E/Slag range for ground granulated blast furnace slag upgrades and its S/Crete range for waste concrete recycling, as well as audits for retrofits. Together, Loesche says that its products can reduce the global cement sector’s carbon footprint by 90%. Within this, Loesche believes that calcined clay technology alone can reduce cement’s CO₂ emissions by 40% and its energy demand by 21%.

Loesche said that its launch during the year of its H₂Optimum grinding bed spraying system can reduce grinding mills’ water consumption by 50%.

Indonesia: The Indonesia Ministry of Environment & Forestry and the provincial government of Aceh have awarded Solusi Bangun Indonesia’s Andalas cement plant a Green PROPER rating. Green is the highest rating in the PROPER awards scheme, which assesses businesses’ environmental and social impacts.

In June 2022, Solusi Bangun Indonesia won the Sustainable Business Awards 2022 award in the category Global Initiatives for Significant Achievement in Sustainability Strategy. The group says that its focus remains on providing sustainable solutions, managing its climate impact, developing the circular economy, preserving water, protecting nature and supporting people and communities.

India: Protestors have halted mining operations at JSW Cement’s Khatkurbahal mine in Odisha, which serves the company’s Sundargarh cement plant. The New Indian Express newspaper has reported that the protestors accuse the company of mining and dumping overburden on neighbouring agricultural land, damaging properties with debris from blasts, drying up six wells and creating excessive dust pollution. The protestors also complained that the mine has failed to create new jobs for local people.

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.”
