Thailand: Siam Cement Group (SCG) will allocate US$6bn between 2025 and 2030 to improve the sustainability of its businesses. The investment focuses on SCG Chemicals and SCG Cleanergy, with the latter increasing its renewable power capacity to 3500MW by 2030 and constructing a new heat battery unit for energy storage at the SCG cement plant in Saraburi. The company is also looking to expand into Vietnam, Indonesia and the Philippines.

President and chief executive Thammasak Sethaudom said “We focus on these businesses as they promise sustainable growth, in line with our inclusive green growth mission.”

India: The city of Tiruchirappalli (Trichy) in Tamil Nadu has entered an agreement with a cement manufacturing unit in Ariyalur to use the city’s non-recyclable plastic materials as refuse-derived fuel (RDF) to power the plant’s kilns. This initiative aims to divert substantial amounts of plastic from the Ariyamangalam dump, starting with 300t/month and increasing over time, with hopes to collaborate with more cement plants, according to the Times of India. The city generates approximately 480t/day of non-recyclable materials, with plans to eventually prevent landfill use completely.

A Trichy official said “A cement manufacturer in Ariyalur has agreed to accept 6 - 8t/day of inert plastic ‘waste’, which will be transported to the plant in a corporation truck. It will be utilised to power the kilns as a substitute for fossil fuel.”

Argentina: Holcim Argentina has introduced the first 100% electric mining truck in the quarry mining industry in Mendoza Province, according to the company. The ‘Pure Electric Mining’ truck, belonging to the XGMT brand, is reportedly set to reduce CO₂ emissions by more than 225t/yr. It also claims to offer further benefits, including reduced operating costs and improved raw material homogeneity. The truck can transport up to 72t and has an energy recovery braking system, allowing the battery to be charged during braking to reduce energy consumption and improve operating efficiency.

Head of decarbonisation at Holcim Argentina, engineer Marilina Moro, said “Sustainability is at the core of our strategy, and as part of this path, we aim to reduce our impact on the planet. That means transforming each of our processes throughout the company's value chain.”

Mexico: Cemex has launched a new water-repellent cement under its Vertua brand, which is designed to extend the lifespan of construction projects by addressing humidity issues. The product reportedly does not require dosing and mixes like traditional grey cement. It was introduced on 12 September 2024 at the Construrama Convention in Mexico.

President of Cemex Mexico, Ricardo Naya, said “At Cemex, we have developed a new specialty cement designed to solve one of the main problems that affects almost every construction site: dampness. Our damp-proof cement is a true ‘all-in-one’. In addition to its traditional use, it incorporates water-repellent properties that not only protect structures, but also provide a smoother, more uniform finish.”

Vietnam: Deputy director of Tan Quang Cement, Tran Van Hung, has proposed reducing cement plant capacity to address the significant supply-demand imbalance. With a current supply of 120Mt/yr and a demand of only 56Mt/yr, the oversupply has led to price pressures, according to the Vietnam News Brief Service. This strategy aims to stabilise prices amid rising input costs and declining sales, further challenged by China's competitive stance and increased export taxes.

Van Hung has suggested regulating plant operations through energy limits and penalties to control supply and stabilise prices.
