US: Sublime Systems’ Sublime Cement reduced-CO₂ cement has received an ASTM C1157 designation. InterestingEngineering News has reported that this enables builders to use it in various projects in line with international building codes. Sublime Systems’ cement consists of lime and silica produced by electrolysis using non-carbonate calcium compounds.

CEO Leah Ellis said "Our aim is to make a profound and lasting impact on global CO₂ emissions. The ASTM C1157 designation is a validation of our efforts to integrate low-carbon innovation into quality construction materials."

Mexico: Holcim Mexico has commenced production of its Fuerte Más reduced-CO₂ cement at its cement plants in Macuspana and Tabasco at a combined rate of 60,000t/yr. The cement offers 50% reduced CO₂ emissions and 10% higher physical performance than ordinary Portland cement (OPC). The El Economista newspaper has reported that Holcim Mexico replaces some of the clinker in the cement with locally-sourced minerals from Southeast Mexico. Chemical compounds in the material colour the cement red.

The Centre for Technological Innovation for Construction (CITEC) Toluca verified the product as suitable for all applications. Holcim Mexico's industrial director Adrián Belli said that comparable green cements are currently only available in France and Italy.

UK: Hanson says it has become one of the first companies in the UK to be certified to the new ISO 19443 standard, for companies supplying products and services that are important to nuclear safety. The subsidiary of Germany-based Heidelberg Materials is a supplier to the nuclear sector and is currently working with three of the delivery teams on the Hinkley Point C (HPC) project.

Stewart Cameron, head of nuclear at Hanson UK said “It has taken our HPC team a year to complete the ISO 19443 process.” He added, “Although it is not a requirement for our supplies to the project, it recognises the efforts we make – and helps others understand – why nuclear needs to be different.”

Spain: The Climate Action Ministry of the Catalonian government has granted an environmental authorisation to Holcim España's 0.9Mt/yr Montcada i Reixac cement plant. The authorisation includes an environmental impact statement for the plant's activities. The Expansión newspaper has reported that the documentation brings the Montcada i Reixac cement plant in line with court rulings, which had found in favour of the Montcada i Reixac city council in ruling that the plant did not have the proper certification to continue operations.

Holcim España employs 327 people at the cement plant, which serves the market in and around Barcelona.

France: Ratings agency EthiFinance has certified Hoffmann Green Cement Technologies' operations as 100% in the line with the EU's Green Taxonomy. The Green Taxonomy measures the sustainability of companies' activities against the European Green Deal's objective of net zero by 2050.

Hoffmann Green Cement Technologies said that it is Europe's first cement producer to achieve the recognition of conformity.

US: The Environmental Protection Agency (EPA) has announced that 10 cements plants have received its Energy Star certification in 2022 from a total of 86 manufacturing plants across all industries. The certification is awarded to the top 25% performers in energy efficiency in each sector. The EPA cited examples of how Titan America’s Troutville plant in Virginia and its Medley plant in Florida had converted production to Portland Limestone Cement (PLC), and achieved a 12% reduction in electricity use and an 18% reduction in CO2 emissions, respectively, thanks to improved energy management. It also mentioned Cemex’s Miami plant in Florida, which increased its energy performance in 2022 by modifying a finish mill, optimising the ball charge on the largest mill and identifying and correcting potential energy losses while also increasing the production of PLC.

Cement plants awarded the Energy Star certification in 2022 include: Drake Cement’s Paulden plant and Salt River Materials Group’ Clarkdale plant in Arizona; GCC’s Pueblo plant in Colorado, Cemex’s Miami plant and Titan America’s Medley plant in Florida; Argos USA’s Harleyville plant in South Carolina; GCC’s Rapid City plant in South Dakota; Buzzi Unicem USA’s Chattanooga plant in Tennessee; Titan America’s Troutville plant in Virginia; and Ash Grove Cement’s Seattle plant in Washington.

Germany: The Science-Based Targets Initiative (SBTi) has validated Heidelberg Materials' new 2030 CO2 reduction targets. The targets have a base year of 2020 and conform to a 1.5°C climate change framework. Per tonne of cementitious material, the producer is now committed to reducing its Scope 1 CO2 emissions by 24%, its Scope 2 CO2 emissions by 65% and its Scope 3 emissions by 25%.

Heidelberg Materials' chief sustainability officer Nicola Kimm said “As reflected in our updated Sustainability Commitments 2030, climate action is a crucial element of Heidelberg Materials’ sustainability strategy. The SBTi validation shows that our sustainability agenda not only includes the most ambitious reduction target in the cement industry – but also a realistic, measurable plan in line with the 1.5°C scenario. We follow a clear, science-based approach, reducing our carbon footprint through the levers of product and process innovation and industrial-scale carbon capture, utilisation and storage. By closing the carbon and material loops, we will lead the sustainable transformation of our sector.”

In 2019, Heidelberg Materials became the first cement company to secure SBTi validation for its emissions reduction commitments.

US: Prometheus Materials’ microalgae-based biocement has secured certification for use in concrete masonry unit (CMU) mixes. The cement now holds an ASTM C129 certificate for use in non-loadbearing CMUs and an ASTM C90 certificate for use in loadbearing CMUs. Prometheus Materials’ biocement produces concrete with comparable or superior mechanical, physical and thermal properties to ordinary Portland cement (OPC)-based concrete. It offers little-to-no CO₂ emissions and 95% of water used in production is recycled.

Prometheus Materials CEO Loren Burnett said “We are thrilled to have achieved these two foundational certifications as we proceed in full force with our goal of decarbonising construction. Prometheus Materials’ product is poised to change the future of construction, converting one of the most carbon-polluting industries to a low-carbon – and one day net-zero carbon – reality.”

Philippines: Germany-based TÜV Nord has awarded three ISO certificates to Philcement Corporation's Bataan cement bagging plant and distribution centre in Mariveles. The facility achieved an ISO 9001:2015 for quality management, an ISO 45001:2018 for occupational health and safety management and an ISO 14001:2015 for environmental management.

Philcement Corporation, a subsidiary of PHINMA Corporation, previously secured a loan towards an upgrade to the Bataan terminal in September 2022.

Chair Ramon del Rosario Junior said “As we continue to provide a reliable and consistent supply of cement products of good quality, these ISO certifications attest to PHINMA, Philcement and our partners’ expertise in this industry. These give us even greater confidence in our operations and especially in the products that we offer our customers."

US: Prometheus Materials has been awarded ASTM C129 certification for non-loadbearing concrete masonry units (CMU) and ASTM C90 for loadbearing CMUs for its bio-cement product. The company is commercialising a process to produce cement and concrete using microalgae.

Loren Burnett, the chief executive officer of Prometheus Materials, said “We are thrilled to have achieved these two foundational certifications as we proceed in full-force with our goal of decarbonising construction.” He added, “Prometheus Materials’ product is poised to change the future of construction, converting one of the most carbon-polluting industries to a low-carbon – and one day net-zero carbon – reality.”
