Sweden: HeidelbergCement says that it will establish a 1.8Mt/yr carbon capture and storage (CCS) plant at its Slite cement plant in Gotland. It aims to achieve full-scale capture of the plant’s CO₂ emissions by 2030. In conjunction with the CCS plant project, Cementa will increase the share of biomass in the Slite plant’s fuel mix.

Chair Dominik von Achten said “Just a few days ago, we published new sustainability targets, underlining the importance of carbon capture, utilisation and storage (CCUS) as one key lever to almost halve our CO₂ footprint by 2030 compared to 1990, and achieve Net Zero by 2050 at the latest.” He continued “Slite CCS is the largest CCUS project yet in our group and the cement industry, and a model for what will be achievable with CCUS also beyond 2030. As this initiative contributes considerably to the climate ambitions of Sweden, and is a unique project for us in terms of scale, we are keen to make it happen.”

Sweden: Cementa has completed its feasibility study for a carbon capture and storage (CCS) system at Slite cement plant in Gotland. The producer says that it will now proceed to the next stage of the project, with the aim of producing climate positive cement from 2030. Sister company Norcem is currently building a 400,000t/yr CCS system at its Brevik cement plant in Norway. Cementa says that its new system will have four times the capacity of that at the Brevik plant, and reduce Sweden's total CO₂ emissions by 3%. One or more of 'several storage solutions' currently under development in the North Sea will serve to store the plant's captured CO₂ emissions.

General manager Giv Brantenberg said "With the knowledge we have built up through our pioneering project at Norcem in Brevik, we now have a good picture of how to move forward in Sweden. The Nordic countries have what it takes to lead the climate transition in the construction sector."

Germany: Schenck Process’ first-quarter sales increased by 21% year-on-year to Euro187m in 2022, led by an ‘outstanding performance’ in its Americas region, according to the company. The company’s adjusted earnings before interest, taxation, depreciation and amortisation (EBITDA) for the quarter were Euro20m, up by 9.3% year-on-year. Schenck Process said that it experienced synergy effects from its acquisition of Thailand-based material processing and packaging company SHAPE and agreed to sell its mining business to Sweden-based Sandvik. It said that a Euro598m order book ensures its ‘continued business momentum’ throughout the remaining quarters of 2022.

Chief executive officer Keith Cochrane said “We continued to demonstrate the resilience of our business by delivering another strong performance in the first quarter of 2022. The disposal of our mining business will enable us to advance a more focused strategy for our other core businesses and strengthen our positions as a global solutions provider for the food, chemical and performance materials as well as the infrastructure and energy markets. Despite a difficult global environment, we are looking forward to a period of further growth building on our recent successes.”

Sweden: UK-based Samson Materials Handling is supplying an Eco Hopper product for installation at the Port of Slite in Gotland. The hopper will be designed to receive clinker, limestone, coal and refuse-derived (RDF) fuel pellets. These materials will be unloaded at the quay area via crane grabs. The hopper will then discharge direct to trucks via a telescopic chute.

The Eco Hopper installation under normal operating conditions and based on the client’s grab sizes and cycle time, will achieve peak discharging rates of: 353t/hr - based on clinker with a bulk density of 1.4 t/m³; 454t/hr - based on limestone with a bulk material density range of 1.8 t/m³; and 420t/hr - based on RDF Pellets with a bulk material density of 0.6 t/m³.

The Eco Hopper product design concept comprises of a specialised reception hopper unit incorporating Integral filter arrangement with a reverse jet filter media cleaning system which returns all material back in to the material stream. In addition, the inlet system of the hopper is based on the Samson Flex-Flap design which reduces the volume of air necessary to control dust both from the opening grab and displaced air from material falling into the inner hopper below. This contributes to the reduction of airflow reducing filter and power requirements of the equipment.

Commissioning and operator training will be provided by Aumund Group Field Services.

Italy: Cementir’s revenue rose by 21% year-on-year to Euro362m in the first quarter of 2022 from Euro301m in the same period in 2021. It attributed this to higher prices linked to the increase in the costs of fuels, electricity, raw materials, transport and services. Its earnings before interest, taxation, depreciation and amortisation (EBITDA) grew by 26% to Euro60.7m from Euro48.1m. Grey, white and clinker sales volumes increased by 1.8% to 2.4Mt and ready-mixed concrete sales volume remained stable at 1.13Mm³. Cement sales volumes grew in Belgium, Denmark and the US but fell in Turkey. Concrete sales volumes grew in Belgium and Norway but fell in Turkey, Sweden and Denmark.

Sweden: Swecem has ordered a 10 000 S type road-mobile ship unloader from Bruks Siwertell for cement handling at the Port of Helsingborg. The unit will have a continuous cement unloading capacity of 300t/hr and is able to discharge vessels up to around 10,000dwt. It will be delivered fully assembled to the operator’s import terminal in May 2022.

Sweden: The government has extended Cementa’s permit to continue mining limestone at the quarries supporting its Slite cement plant for just over one year until the end of December 2022. The cement producer said that it would restart its mining activity immediately. However, it warned that the decision could still be appealed and work stopped whilst the case was pending. The subsidiary of Germany-based HeidelbergCement also refused to rule out shortages of cement in the future due to general uncertainty with the situation. Cementa has now started applying for a three to four year mining permit at the site.

Volvo Autonomous Solutions and Holcim Switzerland announced this week that they are testing and developing the use of autonomous electric haulers in a limestone quarry. It’s a two-part project, as being able to run electric dump trucks will help Holcim to meet its sustainability goals by switching to renewable energy supplies. Automating the control of the trucks then lets Holcim work towards its digitisation targets as part of its ‘Plants of Tomorrow’ initiative. Holcim Switzerland has also been running a drone programme at the plant (see GCW520) and has been using a few electric concrete mixer trucks since early 2021.

The use of autonomous haulage systems (AHS) in quarries by the cement industry seems to mark the start of something new. As far as Global Cement Weekly can tell, the Volvo Autonomous Solutions - Holcim Switzerland project is the first one in the cement sector that has been announced publicly. Most of the examples of AHS to date have been for heavy mining applications such as iron ore, copper, oil sands and coal. Automation in limestone and aggregate extraction has been slower. One recent example in the aggregate sector was announced in late 2020 when Norway-based technology company Steer said it had signed a contract with Romarheim to supply three autonomous dump trucks for use in a stone quarry. Previously Steer has used its vehicles to clear unexploded ordinance for the Norwegian army.

AHS have been around commercially since the mid-2000s when Komatsu tested and then deployed one at a copper mine run by Codelco in Chile. By September 2021 Komatsu said it had commissioned over 400 trucks with its autonomous system and that these had hauled over 4Bnt of materials. For its part Caterpillar says it started its first automated vehicle research program in 1985 and was even testing a pair of Cat 773 dump trucks in the 1990s. However, it then took a pause before resuming after 2000 and starting its commercial projects in the 2010s. In April 2020 it hit 2Bnt of hauled materials by AHS using its MineStar Command product. Hitachi, Liebherr and Belaz have also been working on their own AHS products in conjunction with third party technology providers and these were developed later in the 2010s. Most of these products are complimentary control systems that have been added to existing models or can be added to new ones. Autonomous vehicle company ASI is the other big name in the field with its Mobius product. Unlike the other systems, this is purely a retrofit product. ASI does not make its own vehicles. Komatsu and Caterpillar have also developed retrofit kits for their systems.

Most of the products above look mostly like normal trucks with the addition of extra kit. Volvo and Scania have also been working on AHS but their products have been taking it further by removing the cab entirely. Scania launched its AXL product in September 2019. Volvo launched its Volvo Autonomous Solutions subsidiary in 2020 and its Tara system electric dump truck the same year. Volvo had previously planned to run a pilot for its Tara truck with Harsco Environmental carrying slag at the Ovako Steelworks in Hofors, Sweden. Unfortunately the pilot was disrupted by the start of the coronavirus pandemic shortly after it started.

It’s early days yet with the use of autonomous vehicles in the quarries of the cement and aggregates sectors. Obvious advantages are additional operational hours, better worker safety and reduced costs. As ever with automation, cutting out human jobs would be one disadvantage for the current workers at least. There is also the possibility that an experienced human driver using efficiency software tools might be better than a fully AHS. A challenge in the field is developing open standards or methods to allow autonomous machines to communicate or work with both products by the same manufacturer and its rivals, as well as with conventional human-driven ones. Another challenge is for the mining and quarrying industry to determine how flexible it wants its heavy vehicles to be. One thought to end with this that an autonomous vehicle with a cab and a steering wheel can still be driven by a human. The cab-less vehicles being tested by Volvo and Scania would be rather less useful if they get into a situation where the software can’t cope. Lots to consider.

Sweden: Cementa says it is preparing to ration deliveries of cement in December 2021 due to uncertainty about whether it can renew the mining licence at its integrated Slite plant in Gotland beyond the end of October 2021. The subsidiary of Germany-based HeidelbergCement has warned customers that it is preparing to implement quotas of cement products from its two plants and five terminals on a week-by-week basis. The quotas will be based on what level of cement customers have ordered previously over the past 36 months. It will also take into account whether there have been significant volume changes during the period.

Cementa says it submitted its application for an emergency permit in late September 2021. It needs approval from the government by mid-November 2021 to avoid a potential cement shortage. However, any such approval may be subject to an appeal leading to further delays in mining.

Sweden: Cementa has announced that its Stockholm cement terminal will no longer receive deliveries of its Slite brand cement and will instead begin solely stocking the company’s fly ash cement from 1 December 2021. The producer says that the transition will reduce the carbon footprint of the terminal’s products by 30,000t/yr. Slite cement will continue to be available from the nearby Köping and Oxelösund cement terminals.
