Philippines: Holcim Philippines has appointed Zoe Sibala Senior Vice President of Sustainability and expanded the role of Richard Cruz, Vice President of Health, Safety and Security to include the environment portfolio.

Sibala was Vice President of Strategy from 2017. She held management roles in finance, strategy and business development in Lafarge Philippines’ aggregates unit, which was acquired by Holcim in 2015. She holds a Master of Business Administration (MBA) from De La Salle University and a degree in economics from the University of the Philippines.

Cruz was appointed Vice President for Health, Safety and Security in 2018. Prior to this, he held management roles in the department. He joined Holcim Philippines' waste management unit Geocycle as laboratory engineer in 2008 and helped it attain an Integrated Management System certification (Quality, H&S and Environment). A graduate of the Central Luzon State University, Cruz is a licensed chemist and a certified security professional. He holds certifications in health and safety from accrediting organisations such as the National Examination Board in Occupational Safety and Health and the International Safety Rating System.

Canada: Lafarge Canada has signed a deal with aerated concrete block producer Cematrix to renew its cement supply and joint marketing agreement with the company. The new agreement is effective until 2026.

Western Canada sales and logistics vice-president Cory Cannon said "Lafarge and Cematrix have worked together seamlessly throughout Canada. The extension of these agreements is a natural result of the joint successes we have experienced on numerous projects with the full expectation that this relationship will only continue to grow into the future."

US: LafargeHolcim US, part of Switzerland-based Holcim, has launched its CementDirect ready-mix concrete delivery mobile and web application (app) on the US market. The app consolidates ordering, tracking and shipping records for customers. Plant operators will be able to sign-off on deliveries and access bills of lading remotely.

Supply chain senior vice president Kristin Beck said “More than ever, ready-mix producers are operating under significant constraints. CementDirect allows for easier access to delivery information and removes the daily burden of managing and storing paper.”

Holcim Schweiz hit a milestone recently with the aerial drone programme at its Siggenthal cement plant. The project with Voliro, a Switzerland-based technology start-up, has started to use multi-rotor drones to conduct official measurement flights. They used them to take measurements to determine the steel wall thicknesses of the cement kiln and the cyclone preheater. The work has been part of Holcim’s ‘Plants of Tomorrow’ industrial automation plan with unmanned aerial vehicles (UAV). Key features of the particular drones being used are that they can be rotated around all axes by a special rotor system and can even fly upside down.

Holcim has been using drones in and around cement plants for a few years now. When it launched the Plants of Tomorrow plan in 2019, Switzerland-based drone supplier Flyability said that the cement company had chosen its Elios 2 model to perform confined space inspection. Earlier in 2017 another supplier, SenseFly, said that LafargeHolcim Tanzania had been using its fixed-wing products. Holcim is also far from alone in its use of drones. A few examples among many include Cemex USA’s work with Kespry earlier in 2021, HeidelbergCement’s work in North America and Germany in 2020 and 2021 and Votorantim’s testing at its Córdoba and Niebla plants in Spain back in late 2015. 

UAV usage by armed forces dates back to examples like unmanned incendiary balloons being deployed in the 19^th century to Azerbaijan’s reported decisive use of drones in its war against Armenia in late 2020. The current era of industrial UAVs began after 2000 when governments starting issuing civilian permits, miniaturisation occurred and improvements in cameras, sensors and computing power followed. For the mineral processing sector the trend started with drones being used for stockpile management and quarry surveying. At present this is the main area that UAVs are used for by the sector, often coupled with photogrammetry techniques. CalPortland’s Adam Chapman’s paper at the 2021 IEEE-IAS/PCA Virtual Cement Conference described one company’s use of UAVs in the cement industry since 2016, looking at licensing, cost, quality of data, drone technology, fleet management and field experiences.

More recently though, tests of drones used to survey cement plant buildings and structures have started being publicised such as Holcim’s work at Siggenthal. A presentation by consultant John Kline and Chris Place of Exelon Clearsight summarised the use of drones for structural inspection at cement plants at the Global CemProducer 3 webinar in January 2021. The key benefits they promoted of using an UAV in this way were: improved safety because workers have reduced risk from climbing, working at height or in confined spaces; less time to conduct a survey; higher resolution photographs and video; better coverage through grid method surveying; and an overall lower cost. However, on that last point, other commentators have noted that market-leading drones for surveying are relatively expensive and easy to damage. Drones have since been used to start going inside structures at cement plants with Kline demonstrating their use to inspect the condition of refractory within the cooler, kiln, pre-heater and cyclone of a production line at the Global CemProducer 2 webinar in July 2020. HeidelbergCement has also been doing similar things, with an inspection trial using a drone of the kiln at the Schelklingen plant in Germany during the 2021 maintenance shutdown period at the site.

So far the use of drones by the cement industry has mostly been in a surveying or inspection capacity. Given the short time that UAVs have been used like this there is likely to be scope for lots more development both within existing fields and new ones as the sector works out how best the technology can be used. One application we couldn’t find in the research for this short article was the use of drones for security and surveillance tasks at cement plants and quarries although this may be happening already. However, there could be a more active role for drones if or when a company finds a way for them to start making basic repairs or carrying out simple maintenance in those hard to reach areas that drones excel at accessing. Research examples exist of UAVs being used to spray concrete or repair materials onto minor defects in concrete structures. Yet considerable challenges face these kinds of applications such as the weight of a loaded multi-rotor drone or damage from rebound. Before we all get too worried about drones replacing our jobs though it is worth considering that Amazon’s plan to deliver packages by UAV was first announced in 2013 and it still hasn’t happened yet. It may yet, but for now in most situations humans remain cheaper and more practical than robots or drones.

Nigeria: Lafarge Africa has ranked first on PWR Advisory’s Nigerian Exchange Top 20 companies for gender diversity. 46% of the group’s board seats are female-occupied, up from 40% in 2020.

Chair Adebode Adefioye said “Lafarge Africa's commitment to female representation at the board and management rank and file level is unwavering. Our diversity and inclusion targets, which align with our sustainability strategy, set us apart and are a clear indication of our resolve to continue on this trajectory for more extraordinary outcomes. We remain resolutely committed.”

Canada: Lafarge Canada has supplied the first EcoPact Zero near-zero net CO2 ready-mix concrete in Canada. The subsidiary of Switzerland-based Holcim supplied the concrete to a Habitat for Humanity housing development site in Kingston, Ontario.

India: Holcim subsidiary Ambuja Cements has launched trial production at its new 3.0Mt/yr Marwar integrated cement plant in Rajasthan’s Nagaur district. The launch follows a total investment of US$316m in the plant’s construction. The plant is equipped with an additional 2.0Mt/yr of grinding of grinding capacity and a waste heat recovery (WHR) plant.

Managing director and chief executive officer Neeraj Akhoury said “It’s a proud moment for us at Ambuja Cements. Our endeavour shall always be to become a strong partner and a builder of progress for India."

Switzerland: Holcim Schweiz and Voliro have conducted the first official measurement drone flights at the Siggenthal integrated cement plant. The drone used took measurements to determine the steel wall thicknesses of the cement kiln and the cyclone preheater.

The companies have been testing using aerial drones to conduct inspection and maintenance work as part of Holcim’s ‘Plants of Tomorrow’ initiative. The drones developed by ETH Zürich spin-off company Voliro can be rotated around all axes by a special rotor system and can fly upside down. They are being tested in areas that are difficult for human employees to reach, such as the steel walls and casings of production facilities and silos.

Voliro was founded in 2019 and it is developing a new generation of flying drones for the inspection and maintenance of industrial plants. The drones can be equipped with a variety of sensors that perform visual, thermal and contact-based measurements. The drone's 360° design allows sensors to take measurements even on curved and inclined surfaces. This potentially allows hard-to-reach areas in a cement plant to be assessed without shutting down production. Holcim has been supporting Voliro's product development since 2019 and is providing the technology start-up with the infrastructure in Siggenthal for test flights. The building materials producer has also been supporting the project with its own knowledge about non-destructive testing.

Germany: Holcim Deutschland says it has joined Madaster, an online registry for materials and products. Under the scheme, buildings are registered, including the materials and products that were used in their construction. This is intended to make the reuse or recycling of the materials easier, to encourage ‘smart’ design and to eliminate waste. Thorsten Hahn, the chief executive officer of Holcim Deutschland said “The use of alternative raw materials and the closing of product cycles are among the greatest challenges in the construction industry. We owe it to future generations to use the resources that are available to us responsibly and sensibly.”

India: Holcim subsidiary ACC has signed the Business Ambition for 1.5°C pledge and joined the UN Framework Convention on Climate Change’s Race to Zero campaign. The producer partnered with CDP India’s Science-Based Targets (SBT) Incubator programme to develop its targets. It has committed to reduce its cement’s Scope 1 emissions by 21% to 409kg/t from 511kg/t and its Scope 2 emissions by 48% per tonne between 2018 and 2030. In 2020, the Scope 1 emissions of ACC’s cement were 493kg/t.

CDP India executive director Shankar Venkateswaran said, “CDP India’s SBT Incubator supports companies in India to align with these targets. By committing to science-based emissions reduction targets, ACC has positioned itself as an industry leader, showing the way for the sector’s transformation to a low carbon sustainable future. We believe that this will encourage more companies on their Net Zero Journey.”
