India: Shree Cement has given details of its US$67.8m solar power plant project plans. Projects Tiger News has reported that the producer intends to install 106MW-worth of solar power capacity across several Indian cement plants before October 2022. The company expressed its commitment to reducing its carbon footprint and fossil fuel dependence.

UK: Cemex UK has relaunched its used pallet collection service. The scheme aims to reduce timber waste in its supply chain, according to the company. It forms part of its Future in Action – Committed to Net Zero CO2 climate action strategy. Its partner ELM will collect stockists’ pallets free of charge for refurbishment and return to Cemex UK. It will reuse all repaired pallets and recycle those damaged beyond repair.

Packed cement sales manager Graeme Barton said “We want to make life easier for our merchants to work with us to reduce waste. We’d like to make pallet recovery part of the standard delivery process, as many pallets still end up in landfill. It is increasingly costly to dispose of pallet waste and there is far greater value to be gained by recycling and reuse. Rising timber costs, combined with pallet shortages, means there is a heightened need to conserve and maintain pallets throughout the supply chain. Recovery is considerably more cost effective than buying new replacements.” He added “Pallets are a standard format in transporting building products and contribute a significant financial and environmental cost which needs to be captured by the user. We saw a similar situation with supermarkets and plastic bags, but we’d rather not wait for legislation to enforce this; we’d really like to make a difference now with preventative action. The pallet recovery service is regenerative by design and aims to support the key principals of the circular economy to benefit business, society and the environment. If we all pull together it will have a significant impact across the whole supply chain.”

China: Anhui Conch has signed a CO₂ trading agreement with Shanghai Environmental Energy Exchange (SEEE). The deal takes place within the context of Shanghai’s CO₂ trading pilot scheme. Anhui Conch says that it will not only facilitate the promotion of carbon allowance asset scheduling and carbon asset market transactions, but also provide accreditation and CO₂ management system certification. It says that SEEE will help it to better assume the role of a leading enterprise in the ‘dual-carbon’ field of the cement industry.

Anhui Conch says that it is focusing on developing a full-process carbon footprint monitoring system. It has begun researching the utilisation possibilities of captured carbon with academic partners.

Mexico: Cemex has launched a sustainability-linked financing framework. It says that it is the ‘most comprehensive’ such framework in the building materials sector. The framework further aligns Cemex’s corporate sustainability commitments to its financing strategy, as part of its ‘Future in Action’ program. It establishes Cemex’s guiding principles when issuing new sustainability-linked financing instruments, including public bonds, private placements, loans, derivatives, working capital solutions and other financing instruments. Sustainalytics, an independent company that specialises in providing environmental, social and corporate governance research, ratings and data to institutional investors and companies, validated the framework’s alignment with the Sustainability-Linked Bond Principles, the International Capital Market Association’s Climate Transition Finance Handbook and the Loan Market Association’s Sustainability-Linked Loan Principles.

“Climate change is one of the biggest challenges of our time, and we will continue to address it as a fundamental component of our business strategy,” said Maher Al-Haffar, Cemex's chief financial officer. “Cemex is committed to increasing the role sustainable finance plays in its capital structure by potentially linking the cost of financial instruments to the achievement of targets, directly aligning our corporate finance strategy to sustainability commitments and further contributing to a low-carbon future.”

Cemex has included three key performance indicators in the framework: net CO₂ emissions per tonne of cementitious product, clean electricity consumption and alternative fuels rate. All of them were qualified by Sustainalytics and deemed aligned with the company’s climate action strategy. Cemex currently has a 2030 target of reaching below 475kg/t of CO₂ for cementitious products.

Germany/Brazil: Researchers at the Martin Luther University Halle-Wittenberg in Saxony-Anhalt and the University of Pará in Pará have produced a cement alternative with 66% reduced CO₂ emissions. A type of calcium sulphoaluminate cement, it replaces up to 60% of limestone in clinker with overburden from bauxite mining. Researchers demonstrated that the resulting product conforms to all standards for commercial Ordinary Portland Cement. The results of the research have been published in ‘Sustainable Materials and Technologies.’

Belgium: Holcim Belgium is hosting a public meeting as a preliminary step towards applying for a permit to install a new kiln line at its Obourg cement plant in Mons. The line is intended to replace the existing kiln line as it reaches the end of its operational life. The subsidiary of Switzerland-based Holcim has called the proposed project Go4Zero. The new kiln will be designed to concentrate CO₂ emissions to allow for capture and recovery. Limestone for the plant will be extracted from a quarry at Tournaisis and transported to the plant by railway.

Japan: Sumitomo Osaka Cement has joined the Task Force on Climate-Related Financial Decisions (TCFD) Consortium. The consortium is committed to facilitating effective and efficient disclosure of climate-related corporate information and their use by financial institutions. As a member, Sumitomo Osaka Cement will conduct scenario analysis on the climate change impacts of all its businesses. This includes its cement business, which the company says accounts for the majority of its CO₂ emissions.

South Korea: Sampyo Group has announced a planned investment of US$171m before 2030 to reduce Scope 1 and 2 CO₂ emissions by 35% over the period from an August 2021 baseline. The parent company of Sampyo Cement plans to achieve this in the first phase by increased its use of alternative fuels, improving energy efficiency, introducing low-carbon raw materials such as fly ash and developing sustainable products. The company is targeting net zero CO₂ production by 2050.

Austria: Baumit has invested Euro5.6m in a new waste heat recovery (WHR) system at its Wopfing cement plant in Lower Austria. The producer claims that the installation will enable it to make energy savings of almost 20GWh/yr, corresponding to the energy consumption of 1000 households.

Commercial director Georg Bursik said “We have been using the waste heat for drying systems in the plant for decades. Thanks to this investment, the use of waste heat can be further increased – saving 4000t/yr of CO₂.

US: Solidia Technologies has appointed Russell Hill as its chief technology officer. He succeeds Nicholas DeCristofaro, who will retire in September 2021.

Hill joins Solidia after 25 years working for Boral, most recently as Group Chief Innovation Officer. In 2012, he led the discovery and development of a new series of ‘green’ products that opened new market segments and geography to the building materials producer. Hill holds a doctorate in chemistry from the University of North Texas and is named as an inventor on 56 patents, consisting of over 20 distinct families. He is a member of the American Concrete Institute, ASTM, the American Chemical Society and Alpha Chi Sigma.

Solidia Technologies produces reduced-CO₂ concrete with lower-energy cement and water-free CO₂ curing.
