Japan: Taiheiyo Cement plans to set up a Carbon Neutral Technology Development Project Team in April 2021. The team will develop and apply carbon capture and storage (CCS) technologies for installation at the producer’s cement kilns. The company said that the team seeks to develop cost-practical product for industrial application. Following on from this, it plans to develop CCS technologies which make use of other cement plant processes, and which integrates the circular economic use of industrial by-products. Carbon neutrality is the ultimate aim.

The group said, “By establishing a new project team that is a cross-company organisation, we will gather our wisdom and realise carbon neutrality. We will strongly promote the development of innovative technologies for this purpose.”

Colombia: Grupo Argos subsidiary Cementos Argos has recycled a total of 7m cement bags since 2013 under its Green Bags recycling initiative. The El Nuevo Siglo newspaper has reported that the recycled bags contained 1000t of paper. In water savings alone, the figure corresponds to 80,200m3 - enough water to supply 472,000 people for a day. 159 commercial customers have so far contributed their used bags. In the Medellín metropolitan area, the programme achieved a bag return rate of 95%.The group overcame coronavirus pandemic-related challenges to recycle 15,900 bags in 2020.

Germany: HeidelbergCement has detailed how it uses bonuses to ensure country and cement plant managers achieve their CO₂ reduction targets. Chief financial officer Lorenz Näger explained to financial analysts following the publication of the group’s fourth quarter results for 2020, that a plant’s annual reduction target is calculated against the group-wide ‘525 by 2025’ target of CO₂ emissions of 525kg/t of cementitious material by 2025. Plant performance against this is multiplied with a financial target to determine a manager’s bonus. This enables for the enlargement of bonuses at financially well-performing plants which exceed their emissions reduction targets. A similar mechanism is also used for country managers. Näger called the incentive mechanism a ‘step-changer.’

Pakistan: The National Forum for Environment and Health has awarded Maple Leaf Cement the Corporate Social Responsibility Award 2021 for its contributions to environment and community. The Business Recorder newspaper has reported that the company says it encourages a ‘positive impact’ on the environment, employees, community and all other stakeholders through its activities.

China: The government of Jiangsu province has awarded an Environmental Protection certificate to Imerys subsidiary Calderys’ Zhangjiang refractory plant. The company said that the certification results from years of hard to enhance environmental efforts beyond national requirements. One example of the work is dust-proof partitioning around all dust-emitting equipment.

Environment, health and safety supervisor Ricken Ren said, “In 2016, the plant improved the quality of its raw materials. With major work no longer required to lessen the water content of the materials, it was able to reduce the use of its dry kiln, which uses natural gases in its drying process, in turn greatly reducing the plant’s energy consumption. ” He added, “Keeping the plant’s environmental impact as low as possible is a never-ending job, and we cannot lose focus. We perform daily checks to ensure devices such as our dust collectors are working effectively, and we are always monitoring our emissions during operation according to national laws. Every department worked together on environmental protection performance. It is a great teamwork result.”

Chile: Melón has signed an electricity supply contract with Enel Generación. The contract covers the supply for its La Calera, Puerto Montt and Ventanas cement plants, and its San Bernardo aggregates quarry, until 2043, according to the La Tercera newspaper. All energy supplied under the contract will come from renewable sources. There is also the possibility of expanding the scope of the contract.

General Manager Iván Marinado said, “Our commitment to the sustainability of our operations is permanent. We have state-of-the-art technologies, we work together with our carriers in programmes to reduce logistical impact and energy efficiency, and we have a solid co-processing strategy for the use of alternative fuels (AF) and raw materials. Today we are happy to take a new step and start the use of renewable energies, as a concrete and effective example of our concern to contribute to the environmental improvement of the localities where we operate.”

Mexico: Cemex plans to start using hydrogen as part of its fuel mix at its cement plants around the world in 2021. The estimated cost of the roll-out is US$40m. The company says it completed the deployment of its hydrogen technology across all of its cement plants in Europe in 2020 following trials at the Alicante Cement Plant in Spain in mid- 2019.

Global operations, technical and energy vice-president Roberto Ponguta said, “The fast adoption of this new hydrogen-based technology is a clear example of Cemex's innovation efforts and its strong commitment to decarbonise the cement production process.” He added, "We continue to identify and deploy existing technologies which have a high potential to contribute to our sustainability goals, and hydrogen is a key lever.”

Europe: Cemex commissioned seven new bolt-on investments across Europe in January 2021. The company says that all of the investments are aligned to its key priorities of climate action, sustainable construction and earnings before interest, taxes, depreciation, and amortisation (EBITDA) growth. They include advances in fossil fuel reduction, lower CO₂ footprint products, circular economy investments and products that demonstrate life cycle CO₂ and energy consumption advantages for buildings. It made various changes at its cement plants, for example the installation of a new alternative fuel (AF) system in the Czech Republic. In France and the UK, it made circular economy and recycling improvements, and shifted to lower-CO₂ cement production in Croatia and lightweight concrete production in Spain. Additionally, it made efficiency upgrades to sites in Spain and the UK.

Europe, Middle East and Africa regional president Sergio Menendez said, “We have made a strong start to our 2021 ambitions to both grow our business and improve our climate impact. In 2020, we achieved our ambition of a 35% reduction in our CO₂ emissions compared to our 1990 baseline in Europe. We are also the first company in our sector to align our Europe operations to the EU aspiration to reduce CO₂ emissions by at least 55% by 2030. These investments represent further advances towards this 2030 target, as well as to deliver net zero CO₂ concrete globally by 2050.”

UK: The Transition Pathway Initiative (TPI) has conducted a study into the emissions reduction practices of 33 large cement producers. The study concluded that five of the companies are currently aligned with the emissions reduction pathway which would keep the global temperature rise below 2°C by 2050 compared to pre-industrial levels. This corresponds to 15% of large cement companies assessed in the study compared to 14% of large companies in heavy industries globally. The TPI commended the five producers, noting that in global industry “fewer companies are aligned with 2°C after 2030 [than by 2030], because the pace of decarbonisation required in the industrial sector really picks up next decade, requiring drastic falls in emissions between 2030 and 2050 to meet Paris Agreement goals. More industrial companies need to set longer term targets to 2050 that require greater levels of decarbonisation.” Just one aluminium producer and no paper producers are in line with the 2050 target.

TPI Co-Chair Adam Matthews said, “As we enter the transition decade these hard-to-abate sectors are critical to achieving net zero goals by 2050. Whilst it is concerning that so few industrial companies are ready, it is clear new industrial processes based on circular economy principles give us a tipping point of technically viable, economically attractive solutions.”

Colombia: Cementos Argos transported around 50,000t of cement by train in 2020. It plans to increase this by 30% year-on-year to 70,000t in 2021 as part of its sustainability strategy. The cement producer has started using the Belencito - Bogotá and Puerto Triunfo - Puerto Wilches routes as the country has started to revive railway lines in recent years.
