Egypt: Suez Cement is planning to invest US$20m on an 18MW waste heat recovery unit at its integrated Helwan plant. The subsidiary of Germany-based HeidelbergCement started the project in mid-2021 and expects to complete it by the end of 2022. It is currently negotiating with suppliers and hopes to appoint one soon with construction scheduled for 2022.

US: LafargeHolcim US says that the integrated 2Mt/yr Midlothian plant in Texas will become the first cement plant in the country to fully convert to Portland Limestone Cement (PLC) production. The unit will switch to producing the company’s OneCem product, a blended cement manufactured with up to 15% of finely ground limestone. The move is intended to help LafargeHolcim US and its customers meet sustainable construction goals and lower carbon emissions.

“This is an important, but not unique, step for us. We were the first to produce OneCem, a PLC product, in one of the fastest-growing metro areas in the country, and fuel our industry’s step towards a zero carbon future,” said Patrick Cleary, senior vice president of sales, LafargeHolcim US Cement.

The company is promoting OneCem as an alternative to Ordinary Portland Cement in terms of concrete workability, set time, durability and strength development. It can be incorporated into a broad spectrum of applications that will support foundational structures. The product is available in the Western and Southern regions of the US and the company plans to ‘rapidly’ expand production.

Asia: France-based Fives says it has commissioned a Pillard Novaflam Evolution burner for an unnamed cement plant in East Asia. Due to the travel restrictions linked to the coronavirus pandemic, the commissioning was carried out remotely with the cooperation of the customer. A 143MW coal and petcoke burner with oil as a start-up fuel was supplied as a replacement for an old burner. The aim of this replacement was to increase the kiln capacity to 9000t/day without impacting its NO_x emissions whilst maintaining a good clinker quality despite a high sulphur content in the petcoke. The installation is now in production and an intervention is planned in the coming weeks to further optimise the operation.

Austria: Germany-based Claudius Peters has supplied a conveyor and silos for Schretter & Cie’s integrated Vils Cement plant in Tirol. In the first part of the project Claudius Peters Projects delivered an aeroslide conveying system from the cement mill to the existing silos, including silo bottom aeration systems. For the second part, it built a silo group consisting of three 3500m³ units with expansion chamber technology equipped with truck loading facilities. Each of the silos can be operated at a loading capacity of 250t/hr by a mobile loader with a travelling range of 10m.

Oman: Oman Cement plans to upgrade its 4.2Mt/yr Rusayl cement plant. Reuters News has reported that the producers’ plans consist of a 25% capacity expansion of Line 3 of the plant to 5000t/day from 4000t/day and the construction of a new 10,000t/day Line 4. Lines 1 and 2 will subsequently shut down. Thus, the upgrade will increase the plant’s nominal clinker capacity to 15,000t/day from 8700t/day.

Kenya: Simba Cement plans to begin building a cement plant in West Pokot in 2022. The Star newspaper has reported that the Devki Group subsidiary believes the producer will complete the project 18 months after the start of construction.

Devki Group chair Narendra Raval said “The firm is currently holding public participation and consultative forums with residents and leaders of the area. We want to make sure the community makes the best out of this project.”

Libya: Ahmed Abuhisa, the Minister of Industry and Minerals, has laid the foundation stone for a new cement plant at Al-Shahba. Al-Shahba Cement and National Mining Corporation have signed a deal to build the 1Mt/yr plant in Cyrenaica region, according to the Libya Herald newspaper. The project is part of the ministry’s plan to localise industry in the country, provide job opportunities for young people and drive development. Al-Shahba, which is 100km from the city of Tobruk, is without paved roads and suffers from water scarcity, limited electricity access and the loss of public services.

Brazil: Companhia Siderúrgica Nacional (CSN) has agreed to acquire Switzerland-based Holcim’s Brazilian cement business for US$1.03bn. The business’ assets include five integrated cement plants, four grinding plants and 19 ready-mix concrete facilities. Holcim said that the deal strengthens its balance sheet by ‘significantly’ reducing its debt ratio. It will use the proceeds to invest in its solutions and products business, building its recently acquired subsidiary Firestone. Latin America remains a core strategic growth region, according to the company.

Cheif executive officer Jan Jenisch said “This divestment is another step in our transformation to become the global leader in innovative and sustainable building solutions, giving us the flexibility to continue investing in attractive growth opportunities. We are pleased to have found a responsible buyer with CSN that will develop the Brazilian business over the long term.”

Cementa’s prospects for continued mining limestone in Sweden beyond the end of October 2021 have been looking dubious recently. The subsidiary of Germany-based HeidelbergCement wants to carry on mining limestone at its quarries near its integrated Slite plant in Gotland after 31 October 2021 when its current permits expire. However, the Supreme Land and Environmental Court rejected its renewal application in July 2021 on the grounds that the impact of the quarries on groundwater had not been sufficiently investigated. Then the Supreme Court ruled that it had no basis for appeal at the end of August 2021. This leaves the cement producer hanging on for proposed government plans to make legislative changes to keep limestone mining ongoing for another eight months until mid-2022 and then for whatever scheme the legislators cook up next.

In July 2021 construction multinational Skanska publicly said that it was taking the situation ‘seriously’ because its concrete suppliers had warned it of the impending risk that they would potentially be unable to meet demand in the third quarter of 2022. At the same time the Swedish Construction Federation and related bodies noted that up to 175,000 jobs in construction could be adversely affected with a loss of investment of nearly Euro2bn/month due to the predicted cement shortage. In their view, increasing imports in the short term was unrealistic due to capacity constraints at ports and import terminals. Understandably, the Swedish government has been scrambling to keep the quarries open to protect cement supply and has been accused by both the local press and environmental bodies of circumventing legal norms in the process.

This is not a good situation to be in for either Cementa or anyone who might want to use cement locally in the near future. The cement producer operates both of Sweden’s integrated plants, at Slite and Skövde respectively, with Slite holding around 80% of the company’s production capacity. On its own, the Slite plant alone supplies 75% of the country’s cement, with about another 10 – 15% provided by importer Schwenk Zement. As a whole Cembureau data shows that the country’s market was just under 3Mt/yr in 2020 and stable despite the coronavirus pandemic. A small decline in the residential segment was reported, coupled with a ‘flat’ infrastructure segment, although increased demand from wind farm construction was noted. Cementa stopped production at a third local integrated plant, Degerhamn, in mid-2019 due to low profitability at the site and tightening environmental regulations.

Cementa and HeidelbergCement are putting up a fight by publishing lots of information on Cementa’s website about the permit application process and working towards both solutions in the short and longer term. In early September 2021 Nordkalk signed a deal with Cementa to supply it with limestone. However, as Thomas Lind, the head of cement for HeidelbergCement Northern Europe, pointed out in August 2021, the agreement won’t cover the entire shortfall, nor would it be ideal from logistical or environmental angles. On the opposing side, the Swedish Society for Nature Conservation has joined with the Supreme Land and Environmental Court in opposing the quarry permit renewal along with other environmental groups. Plus the government decision to force through a permit reprieve has also given ammunition to its political rivals.

The argument over Slite’s quarry sums up some of the challenges facing society over continued cement production in a world with ever-tougher environmental legislation. Cement plants are likely to face mounting opposition on environmental grounds but most governments will panic when facing the potential consequences of societies running out of essential building materials. There are many ways to avoid this scenario, such as far greater community and political involvement on the part of cement companies, recognition by governments of the importance of building materials, supporting the development and uptake of concrete made with less Ordinary Portland Cement or switching to higher ratios of other building materials and so on. Yet, without preparation, legislators elsewhere will also find themselves in similar positions to the one the Swedish government is in now.

Slite’s problems have arisen in part over a perceived direct threat to local drinking water, although Cementa says that this is absolutely not the case. Typically, cement plants in similar battles find themselves in opposition to local communities due to the immediate impacts of quarrying or production on water, or due to noise or dust. Yet the hidden consequence of clinker production is significant process CO₂ emissions with resulting global climate change. The particular tragedy in Gotland is that HeidelbergCement is one of the more sustainable-minded cement companies, with investment to match. In June 2021 it announced ambitions to upgrade the Slite plant to become the world’s first carbon-neutral cement plant through bio-based fuel substitution and a carbon capture and storage unit by 2030. This may be eight years away but it is one of very few full scale cement plant carbon capture upgrades that have been promised worldwide.

Sweden: Cementa has said that it ‘views positively’ the Swedish government's rapid action in proposing a new bill on limestone mining licencing. It lobbied the government to stick to its schedule to have a temporary licence in place for Cementa’s use of its quarries in Gotland by 31 October 2021. The group said that it is working ‘with full force’ to find practical and legal solutions to secure the Swedish cement supply in the short and long term.

Sustainability manager Karin Comstedt-Webb said “It will be important that the time frames are not limited by the new bill, but that it enables flexibility to secure Swedish cement supply in the future, so that we avoid ending up in the same problematic situation again in just a number of months.” She added “I want to emphasise that Cementa in all situations works with high environmental requirements. Our ambition remains to be able to show that our industrial operations and the production of the building material cement can go hand in hand with protection of Gotland's nature, water and people.”
