Vietnam: The Vietnamese Ministry of Natural Resources and Environment has expressed environmental concerns about Duyen Ha's plan to convert 423,000m² of forest and and agricultural land into a quarry for its expansion of its Diep cement plant in Ninh Binh province. The expansion will increase limestone supply for a second production line at the plant, Vietnam News has reported. According to an environmental impact assessment report, the expansion will affect 382,000m² of forest and 41,000m² of agricultural land. The total project area will eventually reach 988,000m², capable of producing 2Mt/yr of limestone. The total investment is valued at US$8.8m.

Canada: Finland-based Wärtsilä will provide a hybrid-electric propulsion system for an 11,000t-capacity limestone carrier, commissioned by CSL Group with China-based CCCC Shanghai Equipment Engineering and Jingjiang Nanyang Shipbuilding. The order supports CSL Group’s decarbonisation strategy by optimising engine and battery load and reducing fuel consumption.

The vessel is scheduled for delivery to CSL Group in 2026 and will initially operate on a hybrid diesel and battery system, transitioning to full electric power by 2031 to reduce carbon emissions by 90%, according to CSL Group. Wärtsilä will supply the whole hybrid electric propulsion system, including generators, DC hub, energy management system, main propulsion e-motors, bow thruster e-motors and battery solution.

The director of Electrical & Power Systems at Wärtsilä Marine, Torsten Büssow, said "Wärtsilä is committed to making decarbonised shipping possible, so we are delighted to be supporting CSL with solutions that enhance the sustainability of their fleet. This is a short sea shipping vessel that will operate with a lot of manoeuvring and variable load profiles, and electrification and hybridisation systems are the most efficient for such vessels."

Uzbekistan: Uzbekistan's limestone output reached 0.92Mt in the first quarter of 2024, representing a 50% year-on-year increase, according to the Statistics Agency. The country's construction materials sector also saw a rise in exports, to US$153m.

The government has ambitious targets for 2024, aiming to produce construction materials valued at US$3bn and a focus on local production, the country aims to become self-sufficient and reduce reliance on imports. The country aims to boost exports to US$1.1bn in 2024.

South Sudan: B Smart, an investment company owned by son of a former Malaysian Prime Minister, plans to invest US$100m in constructing a cement plant near the capital city of Juba. The plant is targeted to be operational within 24 months pending necessary approvals, and will use limestone from Kapoeta, 275km east of Juba.

Deputy Secretary for Commerce and Industry, Kuol Daniel Ayulo, said "The plant will reduce the country's reliance on costly cement imports and accelerate infrastructure development."

Brazil: Votorantim Cimentos has inaugurated its first unit in Brazil for Viter, its agricultural inputs business, and Verdera, its sustainable waste management business. Located in Itaperuçu, the unit comprises a new Verdera waste crushing plant and an agricultural limestone production line for Viter. This initiative is part of a US$785m investment programme.

Verdera's Itaperuçu facility has a capacity of 48,000t/yr, tripling its previous capability, and is equipped with technology for sustainable waste treatment. The waste processed at the plant will be converted into clean energy for cement production at Votorantim's plant in Rio Branco do Sul, using co-processing technology developed by Votorantim in Brazil in 1991. Viter's new line will increase agricultural limestone production in Paraná. The Itaperuçu plant, along with the existing Rio Branco do Sul unit, brings Viter's total capacity to 1.5Mt/yr of agricultural limestone in Paraná. The new plant features filters for emission control and utilises biomass as a renewable energy source.

US: The Portland Cement Association (PCA) has commended the Connecticut Department of Transportation's approval of Portland limestone cement (PLC), marking its acceptance in all US states and the District of Columbia. PLC, with increased limestone content, maintains traditional Portland cement's efficacy but reduces CO₂ emissions by up to 10%. The US avoided more than 4Mt of CO₂ emissions in 2023 by using PLC and other blended cements. This achievement coincides with growing cement consumption by state transportation departments, fuelled by the Bipartisan Infrastructure Law.

Mike Ireland, president and CEO of PCA, said "This milestone is a huge step forward for sustainable American construction. Switching to PLC promises to save millions of tonnes of CO₂. Using a lower-emission product that meets all the performance requirements of traditional cement means the construction sector can build with durability, safety and sustainability in mind."

India: Ramco Cements has inaugurated the Gati Shakti cargo terminal at Jayanthipuram in Andhra Pradesh’s NTR District. The company will use the terminal for rail transport of raw materials over 8.3km from the Budawada limestone mines to its Jayanthipuram cement plant. The route will use electric trains.

The company said “Ramco Cements is glad to be a part of the Dedicated Freight Corridor under the Gati Shakti Mission.”

Uganda: The government has granted a 21-year mining licence to Sunbird Resources to support a cement plant project near the border with Kenya. The licence will allow the local company, which is working with China-based West China Cement, to mine limestone, according to Reuters. The partners intend to build a 1Mt/yr integrated cement plant.

Spain: Holcim España’s Viver quarries have received an Environmental Impact Declaration (EID) to expand from 13.5 to 37.5 hectares. This expansion will enable the company to extract 300,000t/yr of limestone to supply its Sagunto cement plant. The EID will allow the company to continue to operate the quarry until 2054.

UAE: Emirates Steel Arkan has concluded a partnership for the deployment of Finland-based Magsort’s technology in steel slag processing at its Al Ain cement plant. ZAWYA News has reported that the partners expect the technology to help reduce the plant’s limestone and fuel consumption. This will reduce its CO₂ emissions by 15%.

Emirates Steel Arkan CEO Saeed Ghumran Al Remeithi said "Green solutions such as this will help decarbonise the sector's value chain."
