Peru: Switzerland-based Maerz has received an order from UNACEM (Unión Andina de Cementos) to supply a 600t/day PFR lime kiln. The kiln will be built and operated jointly at Tarma by UNACEM and Mexico-based lime producer Calidra Group. UNACEM already runs its integrated Condorcocha cement plant in Tarma. The supplier says that the kiln will be ready to install future CO₂ capture technologies due to airtight sealed charging and discharging systems. It will also save up to 20% of electrical energy compared to conventional rotary piston blowers by using high-pressure fans to provide the process air.

Planning is underway for the project and is expected to be completed by the end of 2023. Maerz’ scope of supply will include the petroleum coke firing system, skip winch, charging and discharging systems, high-pressure fans, hydraulic unit and control system. According to the schedule, commissioning should take place in the first half of 2025.

Kosovo: Alba Group has announced plans to build a lime plant in Kosovo, the first in the country. The company has appointed Switzerland-based Maerz Ofenbau to execute the project. The supplier said that it looks forward to many years of cooperation with Alba Group.

Peru: Unacem and Grupo Calidra have received clearance from the National Institute for the Defense of Competition and Protection of Intellectual Property (Indecopi) to launch a joint venture in the lime sector. Carretera News has reported that the new company will establish a 600t/day lime plant, at an investment cost of US$40m. The partners expect to commission the plant in early-mid 2025. Unacem, which holds a 51% stake in the venture, has reported that it and Grupo Calidra will fund the growth from a combination of their own finances and bank loans.

Ethiopia: China-based Sinoma International Engineering has signed an agreement with National West International Holding (WIH) Building Materials to build an industrial park development project at Dire Dawa. The project has an investment of US$600m and will include a 6000t/day cement plant and a 1000t/day lime unit, according to the Xinhua News Agency. The proposed industrial park is relatively close to the Port of Djibouti, in neighbouring Djibouti, to allow for access to raw materials and potential export markets.

WIH, a joint-venture between companies based in Ethiopia and China, already operates a cement plant at Lemi in Amhara Region.

Vietnam: Xuan Thien Group has secured permission for the construction of a US$1.25bn, 10Mt/yr cement plant in Hoa Binh Province. Việt Nam News has reported that the plant will occupy a 48 hectare site in Lac Thuy District. Construction will also involve the clearance of 48 hectare of jungle. Xuan Thien Group is currently also engaged in the construction of a lime plant and solar panel assembly plant in the district.

Thailand: Switzerland-based Maerz has commissioned a new 150t/day lime kiln at Bangkok CaO’s plant at Saraburi. The kiln is the third Parallel Flow Regenerative (PFR) unit that Maerz has supplied to the site following previous installations in 1996 and 2008. All the kilns at the plant use waste oil as a fuel.

China: Jinzhou Tiansheng Heavy Industry has ordered a lime plant with a production capacity of just under 5000t/day from Switzerland-based Maerz Ofenbau. The order includes six PFR-type kilns and will be based at a carbide plant that is being built by Mundra Petrochem, a subsidiary of India-based Adani Group. Maerz says that the new plant will be the largest lime unit ever built at a new site. The equipment manufacturer will supply engineering, material and equipment for the R5S carbide-gas-fired kilns, each with a production capacity of 800t/day.

Scandinavia: Norway-based Aqualung Carbon Capture has secured a contract to supply a membrane-based carbon capture and storage (CCS) system for a Nordkalk lime plant in Scandinavia. The supplier said that each Aqualung Carbon Capture unit has the capture capacity to remove 25% of an average Nordkalk lime kiln's CO₂ emissions. The project will commence in early 2023.

Nordkalk plans to roll out Aqualung Carbon Capture CCS systems across all of its kilns before 2030. Accordingly, parent company SigmaRoc has newly committed to tightened group CO₂ reduction targets under the guidance of the Science-Based Target Initiative (SBTi).

SigmaRoc CEO Max Vermorken said “Our partnership with Aqualung is an exciting next step for the group and the fruit of many months of diligent work by Aqualung and our technical teams in the UK and at Nordkalk. It demonstrates that capturing all process emissions is possible, with existing technology and at industrial scale. Once we roll this out across the group, I believe we will be industry-leading when it comes to our carbon capture strategy, demonstrating again the agility of our business and our business model.”

Aqualung Carbon Capture president and chief technical officer Henrik Utvik said “Aqualung Carbon Capture is extremely pleased to partner with a pioneering company like SigmaRoc to apply our decarbonisation concept in lime production. Due to the size and energy advantages, we believe our technology is ideally suited for this application, and the collaboration with SigmaRoc will fast-track the deployment of full-scale carbon capture installations.”

UK: Wright Engineering has installed new inlet sealings on a kiln at Lhoist's Whitwell lime plant in Derbyshire. The new configuration increases the distance between the kiln's leaf segments and inlet to 400mm. The supplier says that the increased distance from the flow of incoming material will alleviate spillage issues in the kiln.

Uruguay: The Administación Nacional de Combustibles, Alcohol y Portland (ANCAP) has announced plans to find a partner for its cement and lime business. The state-owned company is attempting to restore competiveness to the national market, according to La República newspaper. It will first call for expressions of interest and then take selected offers forward.

ANCAP operates two integrated cement plants, a lime plant and an associated packing and distribution unit. It reportedly made a loss of US$15m in 2021.
