US: Kosmos Cement has ordered a mobile ship unloader from Sweden-based Bruks Siwertell for use at its terminal in Pittsburgh in Pennsylvania. The product is designed to discharge vessels up to 5000dwt and has a continuous rated cement handling capacity of 300t/hr. Delivery is planned for the spring of 2023.

US: Cemex has ordered a type 10 000 S mobile ship unloader from Sweden-based Bruks Siwertell for use at Belle Chasse in Louisiana. The ship unloader was delivered towards the end of 2022, has a continuous rated cement handling capacity of 300t/hr and can discharge vessels up to 10,000dwt.

Sweden: Cementa is running trials on a pilot water treatment plant in the File Hajdar limestone quarry near its Slite cement plant in Gotland. The pilot plant has been running since September 2022 and the subsidiary of Germany-based Heidelberg materials describes the first results as ‘promising.’ The cement company plans to build and pay for a full-scale water treatment plant at the site. Engineering and design company AFRY has been collaborating with Cementa on the project.

Matilda Hoffstedt, the manager of the Slite cement plant, said “We can contribute to greatly strengthening the public water supply here in northern Gotland. The results from the pilot project are extremely promising and we see that a new water plant would really make a difference to the water supply throughout the year.”

Cementa started work on the water project in 2021 with a feasibility study and plans for the pilot. The entire feasibility study is expected to be completed in the summer of 2023 and the goal is to be able to put a full-scale water plant into operation in 2027. However, Cementa says that it needs a long-term permit for its mining operations in Gotland in order to invest in the project. The cement producer has faced opposition to renewing its permit at the site since 2021. A perceived threat to the area’s drinking water supplies has been a repeated concern made by groups against continued quarrying in the area.

US: Argos USA has ordered a 490 M-type ship unloader from Swden-based Bruks Siwertell for cement and fly-ash handling at the Port of Houston in Texas. The unloader will have a continuous rated cement handling capacity of 800t/hr and is designed to accommodate vessels up to 65,000 dwt. It will be assembled on site and is planned for delivery in February 2024. Bruks Siwertell will also supply the complete screw conveyor system for transporting dry bulk material from the unloader to a storage dome, along with support structures and walkways.

Australia: Bruks Siwertell has received an order from Hallet Capital for an enclosed ship unloader for Port Adelaide. A gantry-mounted Siwertell 490 F-type unit has been ordered along with a jetty screw-conveyor system feeding a dome silo and individual screw conveyors for installation inside the dome. The unloader will be suitable for discharging bulkers up to 40,000dwt at a rated cement handling capacity of 500t/hr. It is planned for delivery in August 2023 and will be assembled on site.

Hallett Group announced plans in mid-2022 to build a slag cement grinding plant in Port Augusta, South Australia. The project will also include a new distribution facility at Port Adelaide.

Sweden: The Land and Environmental Court has granted Cementa a four-year permit to continue mining operations in Slite on Gotland. The latest temporary permit was set to expire at the end of 2022. Both the Environmental Protection Agency (Naturvårdsverket) and the county administrative board of Gotland recommended rejecting Cementa’s application earlier in 2022. Prior to this the central government extended the cement company’s mining licence by one year from late 2021.

The subsidiary of Germany-based Heidelberg Materials said that it viewed the latest four-year permit as a ‘bridge’ until it is able to secure a long-term permit. It is aiming to submit an application for a 30-year permit in 2023.

Sweden: Germany-based KIMA Process Control has secured a contract for the supply of a kiln shell cooling system for Cementa's Slite cement plant in Gotland. 88 water jets will deliver centimetre-precision cooling for the 55m-long kiln, while IR pyrometers measure temperatures over areas of 10cm². According to KIMA Process Control, the equipment can avoid unnecessary cooling of the kiln shell, conserving the heat energy supplied by the main burner.

The new cooling system will eliminate the use of energy intensive electric fans, slashing 1700t/yr in CO₂ emissions, according to the supplier. It said that noise emissions will also 'drastically' decline as a result of the upgrade. The system's operating costs are reportedly 98% less than those of the plant's existing fan system.

The supplier said that the new equipment will 'bring the cement plant in Slite an economic benefit in the shortest possible time.' It said "For the cement industry, this project represents a new milestone in terms of best available technology in the operation of rotary kilns."

Europe: The Carbon Negative Biofuels from Organic Waste (Carbiow) project has received EU funding under the Horizon Europe initiative. Carbiow seeks to develop a dense, dry homogenous marine and aviation biofuel by carbonising gasification ash with oxygen and captured CO₂ from cement plants. 12 consortium members from the Benelux, Germany, Nordic countries, Slovenia and Spain are participating in the project.

Indonesia: Solusi Bangun Indonesia has ordered a Siwertell screw-type ship loader from Sweden-based Bruks Siwertell via contractor Hutama Karaya (Persero). The ship loader will be used at Solusi Bangun Indonesia’s Tuban terminal in Java. The HST 1000 1B-type ship loader has a continuous cement handling capacity of 1000t/hr and can load either open-hatched or conventional bulk carriers up to 50,000dwt. It will be assembled on site and is planned for delivery at the end of 2023.

Solusi Bangun Indonesia, a subsidiary of Semen Indonesia, has a cement production capacity of 15Mt/yr. It operates one cement plant on Sumatra and three on Java in Narogong, Cilacap and Tuban. The Tuban site is Solusi Bangun Indonesia’s first new terminal construction.

Sweden: The Environmental Protection Agency (Naturvårdsverket) and the county administrative board of Gotland have both recommended rejecting Cementa’s application to extend its operating permit for its integrated Slite cement plant by four years. At present the current temporary permit will expire at the end of 2022, according to the Dagens Industri newspaper. The county administrative board has requested more information and Naturvårdsverket has found issues in the application with groundwater and nature protection area issues.

Cementa says that it submitted it application to the Land and Environment Court in April 2022 and that it was deemed complete by the court, which announced the application. In July 2022, opinions were received from around 10 authorities and associations, such as the Geological Survey of Sweden (SGU), Naturvårdsverket and the Norwegian Sea and Water Authority. Cementa added that it has now responded to this feedback.

“There are and must be high requirements for permit applications, so it is natural that there will be many views and questions in this type of examination,” said Karin Comstedt Webb, vice president of HeidelbergCement Sweden. “We have now clarified the application further and are now looking forward to the main hearing in October 2022. We are confident that our application is complete and we have been keen to show even more clearly that the business can be conducted in coexistence with nearby residents, and surrounding environmental and natural values. We see good conditions for the timetable announced by the court to be kept, which is crucial for the Swedish cement supply not to be jeopardised in the coming years.”

Further views on the application will be submitted in September 2022. The Land and Environment Court will then hold a hearing in October 2022 and a final decision is expected the end of 2022.
