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.

US: The CalPortland Rillito cement plant in Arizona has received an energy efficiency rebate of US$71,213 from Tucson Electric Power (TEP) as part of a programme providing incentive funds for energy efficiency projects. The cement plant installed an upgrade to its clinker cooler using funding from the TEP Commercial Energy Solutions program. To date, this is the construction materials producers largest rebate in the state of Arizona.

Colombia: Cementos Argos has launched energy saving measures that could contribute close to 10% of the energy saving goals of the Colombian national government. The cement producer has joined the energy savings campaign promoted by the government by taking additional measures at its plants and offices that can help conserve this important resource.

Cementos Argos intends to deliver excess energy from its self-generation plants of about 30MW to the domestic electrical network and limit the use of its 16 cement mills during peak hours, which will represent savings of about 38MW. In addition it will maximize its use of flexitime and day work to limit the use of electrical energy at its administrative offices. With these measures the company hopes to save the equivalent of the consumption of close to 100,000 homes per day and of close to 130,000 homes during peak hours.

“We are convinced that by joining our efforts, we can multiply results. That is why, if all companies and families put their best foot forward, we can all contribute to energy saving and create habits that allow us to preserve resources that are fundamental to our planet’s sustainability,” said Jorge Mario Velásquez, CEO of Cementos Argos.

Uzbekistan: Qizilqumsement and Bekabad Cement intend to conduct energy saving projects at their plants by the end of 2020, according to local press.

Bekabad Cement, in partnership with the World Bank, is upgrading its aeration system and the products transportation system at its cement silos. The upgrade will save more than 3MkW/hr of electric power per year. The plant is also installing a new cement ball mill with a capacity of 135 – 150t/hr. This is planned to reduce power consumption by 20%.

Qizilqumsement plans to reduce its gas consumption by 46.6Mm³, and power consumption by 57MkW/hr. A clinker silo will be built, the clinker plant will be upgraded and the closed circuit cement milling will be launched for mill #7.
