Nepal: IME Group plans to build a US$90m cement plant at Chormara of Nawalparasi. The unit is scheduled to be commissioned in early 2024, according to the Kathmandu Post newspaper. This will follow one year of preliminary work, one year for fund raising and the next two years for construction. The plant will mine limestone from a quarry in the Madanpur and Sisdi Rural Municipalities of Palpa district. The quarry will be 25km from the designated plant site. The mine has 18.7Mt of limestone according to a report by Investment Board Nepal.

UAE: RAK Cement has postponed its acquisition of Newtech cement and the Al banna quarry due to incomplete financing. It previously announced the purchase in late February 2019. It planned to buy the assets for around US$123m.

Spain: LafargeHolcim España says it is considering whether to keep its Sagunto cement plant open due to a dispute with the local government over an expansion to its quarry. The Valencian local government is set to block the plans, according to the Expansión newspaper. The cement producer maintains that preventing the expansion of the quarry will damage the plant’s development in the short to medium term.

UAE: Ras Al Khaimah (RAK) Cement has purchased the Newtech cement plant and the Al Banna quarry from Mohammed Ali Omar Saleh Al Buraiki for around US$123m. RAK Cement operates an integrated plant at Ras Al Khaimah.

Europe: Cemex has signed a deal to sell its assets in the Baltic and Nordic countries to Germany’s Schwenk for Euro340m. The transaction is expected to complete within the first quarter of 2019, subject to regulatory approval.

The Baltic assets being divested consist of one 1.7Mt/yr integrated cement plant in Broceni, Latvia, as well as four aggregates quarries, two cement quarries, six ready-mix concrete plants, one marine terminal and one land distribution terminal in that country. The assets divested also include Cemex’s approximate 38% indirect interest in a 1.8Mt/yr cement plant in Akmene in Lithuania. In addition, the exports business to Estonia is also included as part of the divestment.

The Nordic assets being divested consist of three import terminals in Finland, four import terminals in Norway and four import terminals in Sweden.

India: Birla Corporation’s earnings before interest, taxation, depreciation and amortisation (EBITDA) rose due to increased sales of blended cement in the last quarter of 2018. Blended cements represented 89% of its total sales volumes compared to 85% in the same period in 2017.

The company’s net sales grew by 14.6% to US$653m in the nine months to the end of 2018 from US$569m in the same period in 2017. Its EBITDA rose by 17.1% to US$96.8m from US$82.7m. Its cement production increased by 10.5% to 9.86Mt from 8.92Mt and its cement sales increased by 9.9% to 9.79Mt from 8.92Mt. It said that better sales in key markets had offset raw material price rises such as petcoke, coal and diesel. It noted that the price of diesel had risen by over 20% in the reporting period although it had started to soften in the most recent quarter.

The cement producer held a ground breaking ceremony in late January 2019 for a new plant being built by its RCCPL subsidiary at Yavatmai district in Maharashtra. The 3.9Mt/yr unit has an investment of US$342m and it includes a 40MW captive power plant and a 10.6MW waste heat recovery (WHR) system. Commissioning is scheduled for the 2021 – 2022 financial year. The company is also planning to upgrade RCCPL’s plant at Kundanganj with 1.2Mt/yr of additional production capacity. Other new projects include a 12.25MW WHR system at Maihar that is expected to be commissioned in mid-2019. It is building solar power plants at Maihar, Chanderia and Satna with 11MW, 3.6MW and 1.2MW capacity respectively. Birla Corporation also said that restrictions on using explosives placed on limestone mining at Chanderia in Rajasthan had increased its costs.

UK: A consortium comprising Aggregate Industries, Innovatium and the University of Birmingham has gained funding from the Department for Business, Energy and Industrial Strategy (BEIS) to test a liquid air energy storage (LAES) energy efficiency technology under the government’s Industrial Energy Efficiency Accelerator (IEEA) programme. The IEEA programme, administered by the Carbon Trust on behalf of BEIS, will provide nearly Euro0.4m towards delivering a new compressed air system utilising LAES technology from initial laboratory testing to full operation at Aggregate Industries’ Bardon Hill quarry in Leicestershire.

PRISMA (Peak Reduction by Integrated Storage and Management of Air) by Innovatium is a LAES technology that stores energy in liquid air form to provide compressed air, allowing inefficient partially loaded, variable-demand compressors to be turned off, thus improving the total system efficiency by up to 57%. The PRISMA system will bring together a latent energy cold storage tank, filled with a phase change material (PCM) to store thermal energy, and a number of other off-the-shelf components to form a system that will work with Aggregate Industries’ existing compressed air network. The research group says that the integration of the equipment and components in an industrial setting, for the provision of compressed air, has never been attempted before.

“The project will help to address the ‘energy trilemma’ of managing energy efficiency, energy cost and energy security by: significantly improving the energy efficiency of our compressed air system; managing electricity costs by running the compressors out-of-hours, when electricity is cheaper; and helping to smooth and reduce the peak electrical demand on site. We are therefore very excited to be the first industrial partner to install the PRISMA system at our Bardon Hill quarry in Leicestershire,” said Richard Eaton, Energy Manager at Aggregate Industries.

The 24-month project will involve the development of the PCM at the University of Birmingham’s School of Chemical Engineering as well as the design, manufacture and assembly of multiple system components by Innovatium before installation of the system at Bardon Hill. The PRISMA Project has currently only been deployed in a simulated environment. Following successful delivery of the project, this scalable technology has multi-sectoral applications for compressed air systems both in the UK and globally. In the UK, the compressed air market is estimated at 1.3GW of installed electrical capacity across around 4500 sites and over 55,000 individual compressor units.

Spain: Cementos Tudela Veguín has purchased a full stake in Caleras de San Cucao, a lime producer based in Asturias, according to the La Nueva España newspaper. No value for the acquisition has been disclosed. The company operates a lime plant at Llanera and it runs two lime quarries at Agüera and Las Regueras. Cementos Tudela Veguín has a lime production capacity of 0.6Mt/yr from its Tudela Veguín plant in Oviedo.

Spain: LafargeHolcim España has restored land at a quarry near its Jerez de la Frontera cement plant in Cadiz. As part of biodiversity improvement project it has recovered 45 hectares of land and planted around 35,000 trees.

Sweden: Conveyor belts supplied by Germany’s Continental are being used in the Förbifart Stockholm road infrastructure project. HeidelbergCement’s aggregate company Jehander is using Continental steel cord conveyor belts at its Löten quarry near Stockholm to allow rubble from tunnelling to be reused for road construction. In addition, drilling machines from Epiroc are using Continental DrillMaster tyres to provide high cut resistance, good traction and stability.

Overall, around 5.5Mt of rock will be extracted to build the tunnels required for the new bypass. A series of conveyor belt systems are being used to transport the extracted rock to three temporary ports that have been set up for the project. The rubble is taken across the waterways by inland vessels from the construction site in Stockholm to Löten. The rubble is then reused as concrete, mostly for road construction, or it used for local construction.
