Croatia: Cemex Croatia has won contracts to install solar power plants at three of its facilities, co-financed by the EU's Modernisation Fund. The company will build new solar plants at Sv. Juraj and Sv. Kajo cement plants in Kaštel Sućurac and Solin, respectively, and at the Podsused production facility in Zagreb. The total investment is valued at €5m.

The solar power plants, with a combined capacity of 6.34MW, will be installed on the roofs of these facilities. The Sv. Juraj plant will receive a 3.79MW system worth €3m, the Sv. Kajo plant a 2.14MW system valued at €1.7m, and the Podsused facility a 0.41MW system costing about €318,000. The EU's Modernisation Fund will cover 60% of the costs for the Sv. Juraj and Sv. Kajo projects and 50% for the Podsused project.

"The savings that these measures will bring to us in terms of energy consumption will increase the efficiency of our production and reduce emissions from our operations. These are just some of the projects we are planning to achieve our climate goals" said Marijan Zekić, Cemex Croatia’s project and quality assurance manager.

Germany: IKN and KIMA Process Control are planning to work together on optimising energy recuperation and reducing the carbon footprint in clinker production by integrating machine learning software. The collaboration is intended to combine the expertise of KIMA Process in process automation and IKN as a process expert and equipment supplier for clinker production. The synergy should lead to more streamlined and efficient operations and highly reliable top-quality equipment.

In a statement the companies said, “We are excited about the potential of this collaboration to reshape the landscape of clinker production control and setting new benchmarks in the cement industry.”

US: Holcim US has joined the Department of Energy's (DOE) 'Better Climate Challenge' to reduce CO₂ emissions and save energy. It is the first cement producer to commit to the DOE program. The subsidiary of Switzerland-based Holcim plans to power the electrical operations at 13 cement plants in the country with 100% renewable energy by 2030 and to reach net zero CO₂ emissions by 2050. As part of the 'Better Climate Challenge' it has committed to reduce CO₂ emissions in the US by at least 25% by 2033.

Examples of current renewable power usage at Holcim US cement plants include the installation of three onsite wind turbines at the Paulding plant in Ohio that generate 11,500MWh while a forthcoming solar unit at the Hagerstown plant in Maryland will generate up to 18,440MWh. All 13 Holcim cement plants will conduct reviews to identify projects that could contribute to meeting goals of the challenge.

With grant support from the DOE, Holcim is also investigating the feasibility of using carbon capture utilisation and storage (CCUS) at its cement plants in Portland, Colorado, and Ste. Genevieve, Missouri. In addition to involvement in the Better Climate Challenge, Holcim US is a continuing partner of the DOE's 'Better Plants Challenge', sharing facility-level energy data and solutions to help guide other industrial companies with implementing energy solutions in their facilities.

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.

India: UltraTech Cement says it has beaten its goal of doubling its energy productivity ahead of its deadline. It joined the EP100 initiative in 2018 and agreed to double its energy productivity from the base year of 2010 with the target year of 2035. It has achieved this by investing in energy efficiency measures such as upgrading clinker coolers, implementing variable frequency drives to manage electricity flow, and introducing new waste heat recovery systems. The company says it is focusing on new technologies, changes in product and energy mix, digitisation and carbon pricing. It foresees the digitisation of its energy performance as a key enabler for identifying the best opportunities to save energy.

"UltraTech firmly believes that companies in the building material sector can come together to step up climate action for meeting the global 1.5-degree ambition. Joining like-minded companies in EP100 gave us an opportunity to accelerate and scale-up levers to double energy productivity and also drive the decarbonisation agenda,” said Kailash Jhanwar, the managing director of UltraTech Cement.

EP100 is a global business initiative consisting of a group of companies committed to improving their energy productivity. EP100 is led by the Climate Group, an international non-profit organisation, in partnership with the Alliance to Save Energy.

Germany: ThyssenKrupp has announced the launch of the HPGR Pro, a high-pressure grinding roll for raw materials processing that it says “offers up to 20% more throughput, 15% lower energy consumption and 30% longer-lasting rollers” than previous models. HPGR global product manager Frank Schroers said, “We used our experience and what we learned from conversations with customers to introduce improvements that are unique in this market and make grinding much easier.” Laser monitoring keeps users constantly informed about the roller surface and helps predict the best possible time for roller replacement. “Our customers need no longer stop the machine as a precautionary measure, saving them valuable time. What’s more, as our specialists collect and process machine data, our customers can continually improve their HPGR’s operation and optimise throughput, energy consumption or machine availability in line with their specific targets,” added Schroers.

Thailand: Germany-based KHD Humboldt Wedag has reported the successful commissioning of a new Comflex grinding line at Siam City Cement’s Plant 1 in Saraburi. The line replaces two ball mill circuits, maintaining a production capacity of 350t/hr with a 40% lower energy consumption. The Comflex comprises a roller press, RPM18–200/180 static coarse material separator, VS620 static fine material separator, LS8600 system fan, HKSK 236/346 and four product separation cyclones. KHD says that Siam City Cement awarded it the engineering, procurement and construction (EPC) contract because of the system’s low specific power consumption of 13.36kWh/t, compared to over 21kWh/t in the previous system.

China: Hebei province-based Tangshan Jidong Cement’s net 2019 profit was US$298m, up by 42% year-on-year from US$210m in 2018. Cement and clinker sales remained flat. Tangshan Jidong Cement attributed the growth to increased prices due to a 9.9% year-on-year increase in infrastructure spending to US$1.86tn. Throughout the year, the company said, it completed energy-saving optimisation and upgrades to improve efficiency, implemented strategic marketing and reduced the cost of material procurement.

UK: Lafarge Cement, part of Aggregate Industries, has achieved BS EN ISO50001:2018 in Energy Management Systems after demonstrating its on-going commitment to energy efficiency. The certification requires companies to show continuous improvement in reducing the energy intensity of their operations.

Philippines: Holcim Philippines’ Bacnotan and Norzagaray cement plants have won awards for energy efficiency at the 2016 Don Emilio Abello Energy Efficiency Awards. The plants won Awards of Recognition for representing the Philippines in the Association of Southeast Asian Nations (ASEAN) Competition Best Practice for Energy Management in Buildings and Industries. The La Union plant was cited for its use of alternative fuel and raw materials to reduce its coal consumption, while Bulacan was recognized for its best practices in energy management through process improvements.

Plants operated by Holcim Philippines in Misamis Oriental and Davao City picked up awards for energy efficiency in 2015. In 2014, the company’s Bulacan plant was elevated to the Hall of Fame for receiving the Outstanding Award for three consecutive years.

The Don Emilio Abello Energy Efficiency Awards, run by the Department of Energy, recognise firms that significantly reduce their energy consumption. Participating companies submit consumption reports that are evaluated by energy officials from the public and private sector. The award is a tribute to Emilio Abello, the former Meralco chairman and chief executive officer.
