UK: Cemex UK has announced the publication of Environmental Product Declarations (EPDs) for its cement products manufactured at the Rugby and Tilbury plants. The EPDs are for the cement delivered in bulk tankers, covering over 80% of its manufactured cements.

Head of sustainability for Cemex Europe, Paul Fletcher, said "Achieving third-party verification through the International EPD System provides independent and transparent information of our cement’s environmental performance over the entire lifecycle of the product."

France: Irish cement producer Ecocem plans to industrialise a new technology that will be implemented at its Dunkirk site in northern France by 2025. The technology, called ACT, replaces clinker with limestone filler to reportedly reduce the carbon footprint of cement by 70% compared to the average French cement.

The company is relying on public funding from Bpifrance, the Hauts-de-France region and the urban community of Dunkirk.

US: Holcim US in Missouri will receive US$1.37m from President Biden's Inflation Reduction Act to support the reduction of climate pollution in manufacturing construction materials, as announced by the US Environmental Protection Agency (EPA). The grant is part of a broader effort to reduce emissions from the manufacturing industry and will aid Holcim's Environmental Product Declaration Accelerator Project.

EPA Region 7 Administrator, Meg McCollister, said "We commend Holcim for its work in advancing sustainable practices to reduce carbon emissions here in the Heartland and across our nation. Its innovative approach, supported by this grant, advances climate-friendly practices and sustainability in one of our nation's most important industries."

Canada: Minister of Environment and Climate Change, Steven Guilbeault, announced the reinvestment of up to US$1.6m from industrial pollution pricing proceeds into a new emissions reduction project at St Marys Cement in St Marys, Ontario. This initiative will involve the installation of a new kiln utilising low-carbon fuels, including discarded plastics, to reduce the use of carbon-intensive fuels used in the manufacturing process by up to 30%. The project aims for a reduction of over 39,900t of greenhouse gas emissions by 2030, according to Foreign Affairs news.

India: Oriana Power has received an order for a 40MWp solar power plant in Rajasthan from a cement producer. The project is valued at US$18m. Oriana will provide engineering, procurement and construction, alongside the commissioning, operation and maintenance of the plant. The plant is scheduled for commissioning in April 2025, with a subsequent operation and maintenance period of 25 years.

Oman: Oman's solid waste management entity, Be'ah, has reported progress in its strategy to transition solid waste from landfill disposal to refuse derived fuel (RDF), according to Oman Daily Observer.

In 2023, Be'ah launched initiatives focusing on transforming waste into RDF, electrical and electronic waste and green waste. The company has signed an agreement with Oman Cement Company to provide tyre derived fuel for its energy needs, eventually expanding to include RDF. A memorandum of understanding (MoU) was signed with Oman Cement during Oman Sustainability Week to explore the utilisation of RDF as an additional alternative fuel source, according to the company’s 2023 sustainability report.

Chair of Be’ah, Ahmed al Subhi, said "We take pride in our strategic resource management initiatives, having set ambitious targets for transitioning to a circular economy, including achieving 60% waste utilisation by 2025 and 80% by 2030.”

US: Vineyard Offshore has agreed to buy 2000t of cement from Sublime Systems, a Massachusetts startup planning a US$150m ‘carbon-free’ cement plant in the city. The cement will be used for turbine platforms and onshore civil works within the Vineyard Wind 2 project, aiming to reduce its carbon footprint. This agreement is contingent on the project's selection in upcoming solicitations.

Germany: Cemex Deutschland has partnered with recycling service provider Alba to construct a new biochar production facility at its Rüdersdorf cement plant in Brandenburg. Named ALCE, the project will utilise biogenic waste to produce biochar, aiming to reduce greenhouse gas emissions from cement production. This initiative is part of the Carbon Neutral Alliance, targeting carbon neutral cement production at Rüdersdorf by 2030.

South Korea: South Korean cement manufacturers recently convened at an event hosted by the Korea Cement Association and the Korea Industry Alliance Forum to discuss how to achieve carbon neutrality. The industry currently faces financial challenges in upgrading equipment due to low cement prices. However, it has achieved a 20% decrease in greenhouse gas emissions per tonne of cement since 2014, aided by the use of alternative fuels and investment in energy efficiency. The Korean government now requires that greenhouse gases be cut by 12% by 2023 from 2018 levels by 53% by 2050.

The industry currently uses post-consumer plastics as fuels instead of fossil fuels and incorporates byproducts from other industries, like sludge. However, some environmental groups have labelled cement made from industrial byproducts as ‘garbage cement’ claiming it contains hexavalent chromium levels more than four times the EU’s allowable limits. The use of plastics as alternative fuel has also sparked complaints from local waste collection and incineration companies, who argue that cement companies are taking away their business.

Professor Kim Jin-man from Kongju National University said "We also need to focus on developing high-performance clinker, advanced chemical admixtures for concrete, and accelerators that shorten concrete curing times."

Italy: NovaAlgoma, a joint venture between the Italian-Swiss Nova Marine Carriers and Canada's Algoma Central Corporation, has announced the construction of the ‘world’s largest and greenest’ cement carrier, weighing 38,000t. This vessel will be built by Xinle Shipbuilding in China and delivered by the end of 2026. It will reportedly be the first to use both traditional fuel and methanol and can connect to electrical grids in ports to eliminate emissions, according to local news reports. Additionally, it will feature a waste heat recovery system that converts exhaust gases into 250kW of electrical energy.

Vincenzo Romeo, CEO of Nova Marine, said "This new construction, which meets the forecasts for the development of our fleet and the growth of cement market demand in the coming years, is intended to consolidate our positioning among the global leaders in cement transportation.”
