Sweden: Germany-based HeidelbergCement subsidiary Cementa plans to upgrade its Slite unit in Gotland to become the world’s first carbon-neutral cement plant. This will be achieved through modification of the plant’s fuel system to ‘significantly raise’ biobased fuel substitution, as well as 100% carbon capture and storage (CCS) via a 1.8Mt/yr CCS installation. Full-scale capturing of the plant’s CO₂ emissions is scheduled by 2030.

Chair Dominik von Achten said, “HeidelbergCement will be the leader in the global cement industry on its transformation path towards climate neutrality. The key for decarbonising our industry is to find, apply and scale technical solutions for carbon capture and utilisation or storage (CCU/S). After having gained valuable experience with CCU/S technologies in Norway and other countries, we are now excited to make the next step with a completely carbon-neutral cement plant in Sweden.”

Canada: The Cement Association of Canada (CAC) and the government have published a joint statement detailing their plant to develop a roadmap to net-zero carbon concrete. When launched in December 2021, the roadmap will provide Canadian cement producers with the policies, tools and technologies to contribute to the achievement of net-zero concrete by 2050. The plans will cover areas including: supporting the low-emissions building materials supply chain, building an innovative opportunities framework and engaging stakeholders. According to the statement, the roadmap will offer total potential CO₂ reduction of 15Mt by 2030, and 4.0Mt/yr thereafter.

The partnership will establish a CAC-led Industry-Government Working Group in collaboration with the National Research Council the Standards Council of Canada and Innovation, Science and Economic Development. Among its tasks will be the publication of updated environmental product declarations.

UK: Hanson, part of Germany-based HeidelbergCement, has supplied basalt from its Builth Wells, Powys quarry to the world’s first CO₂ sequestration field trial in the Brecon Beacons. The trial uses local live soil enriched with basalt for enhanced CO₂ sequestration in a reforested 11ha woodland. Enhanced rock weathering takes crushed basalt, a by-product of quarrying, and applies it to the soil to capture CO₂ and provide essential nutrients to fertilise trees and the fungi in the soil that support tree growth. The building materials producer says it is a method that has been proven to be successful in sugar beet and pea crops.

Sustainability director Marian Garfield said, “Hanson is focussed on climate protection and carbon reduction, and enhancing biodiversity net gain are two of our key 2030 commitments.” She added, “We are excited to be involved with this project, which aims to determine whether basalt can accelerate the removal of CO₂ from the atmosphere in the creation of new woodland and could therefore potentially play a vital role in helping tackle the climate crisis.”

Spain: Cemex España, part of Mexico-based Cemex, has launched a new CEM-II grey cement with approximately 20% reduced-CO2 direct emissions as part of its Vertua low-carbon product range. The company says that the product provides early strength like a CEM-I cement. It says that this makes it highly suited to precast concrete and infrastructure applications. Cemex says that it will launch the product in other European markets in 2021.

Cemex is committed to 55% emissions reduction by 2030. It said that prior to this commitment it, “had already achieved a close to 35% emissions reduction by 2020.”

Australia: Adbri says it wants to achieve net zero carbon emissions by 2050 as part of its commitment to a low carbon future. The board and management team are assessing medium and long term emissions reduction options and are intend to release a roadmap by the 2022 annual general meeting. Adbri set its current emissions reduction target in 2019, to deliver a 7% reduction in its greenhouse gas emissions by 2024 against 2019 baselines. In 2020 it achieved 2.3% reduction.

“We recognise that process emissions from the production of cement and lime are not easy to abate. Adbri is committed to maintaining its sector leadership position in sustainability by continuing to increase its use of renewable energy, alternative fuels and supplementary cementitious materials. Developments in technology and partnership with industry, government and research institutions will be critical as we deepen our understanding of long term emission reduction options. This will form part of our roadmap toward net zero by 2050,” said Adbri’s chief executive officer Nick Miller.

Taiwan: Asia Cement Corporation has completed its US$1.3m full shore power project for its cement vessels. Following the upgrade its cement carriers use the ‘Taipower’ power supply when berthed at port instead of using on-board generators. The project has been implemented at the ports of Kaohsiung, Taichung, Keelung and Hualien. The cement producer currently operates four cement carriers.

The shipping upgrade is expected to save over 1474t/yr of fuel oil and effectively reduce 5329t/yr of CO₂ emissions. The cement producer added that it would improve the unloading efficiency of cement carriers, decreasing the unloading time by 50%, and reduce wear on the ship generators.

Mexico: Cemex says that it has supplied its low-CO₂ Vertua concrete to 786 construction works in Mexico. The El Sol de San Luis newspaper has reported that the volume so far delivered totals 33,000m³. In late May 2021, 398 further projects have placed orders for future deliveries.

Mexico: Cemex has partnered with UK-based oil company BP to accelerate the progress of its ambition for net-zero CO₂ concrete by 2050. The partners have signed a memorandum of understanding to develop cement production and transport decarbonisation solutions. Such solutions include the transition to reduced-emissions power and vehicles, energy efficiency-improvements, carbon capture and storage (CCS) and carbon offsetting. In addition, the companies will collaborate on urbanisation solutions to decarbonise cities.

Sustainability, commercial, and operations development executive vice president Juan Romero said “Concrete plays an integral role in society, and there are no substitutes for its key attribute – strength and resilience. We believe it will continue to have a critical role in a low carbon economy, and the challenge for the industry is to find solutions to the manufacturing process emissions.” He added “This initiative with BP is another example of the work we are doing with partners across industries, academia, and startups to tap into the latest innovation and disruptive technology to achieve our ambition of delivering net-zero CO₂ concrete globally to all of our customers.”
