India: Shree Cement has hired FLSmidth to supply a 11,5000t/day kiln line for its planned Nawalgarh, Rajasthan, cement plant. The line will consist of a six-stage preheater and a three-support kiln. The supplier will also deliver an OK vertical roller mill, which it says has a 5 – 10% lower energy consumption than a standard vertical roller mill. The project focuses on sustainable productivity and emissions control. Shree Cement has opted for JetFlex burners to give the lowest possible nitrous oxide emissions for various fuel types.

Shree Cement managing director Prashant Bangur said “Based on the experience of working with FLSmidth on the installation of a 9,000t/day pyro system at the Raipur, Chhattisgarh, cement plant earlier this year, we felt confident about approaching Carsten Riisberg Lund and his team regarding the Rajasthan project.” He added “Being recognised as a Sustainability Champion by the World Economic Forum is a testament of our emphasis on sustainability at every stage of our operations. The new line will push that agenda even further in terms of lowering the benchmarks on energy consumption and emissions, and thereby reducing our environmental footprint.”

FLSmidth also supplied a second OK mill for Shree Cement’s operations in Kolkata, West Bengal.

Poland: Cemex Poland has established a new 50kW solar power plant at its Pruszków ready-mix concrete production plant in Masovian Voivodeship. The company says that it is planning other investments to retrofit renewable energy systems into its operations across Poland.

Materials director Michał Grys said “Cemex is actively addressing the climate challenge by decarbonising our processes. The key to realising our ambitious goals is finding and implementing new low-emission products as well as more sustainable technologies and construction solutions.” He added “Photovoltaic farms are another investment by Cemex Poland in renewable energy sources. Currently, much of the electricity used in our aggregate quarries, cement plants and many concrete plants comes from renewable sources."

India: Udaipur Cement Work plans to increase its reliance on renewable power with the installation of a new 4.15MW solar power plant at its cement plant in Udaipur, Rajasthan. When operational, the installation will increase the Udaipur plant’s solar power capacity by 42% to 14.3MW. The producer says that its entire solar power apparatus will facilitate a reduction in CO2 emissions of 14,000t/yr. In the 2020 and 2021 financial years, the producer consumed 13,000MWh of solar power, reducing CO2 emissions by 10,000t.

Pakistan: DG Khan has connected its upgraded Hub cement plant and power infrastructure to the national grid. The Pakistan Observer newspaper has reported that the facilities generate 40MW of power via a 10MW waste heat recovery (WHR) plant and 30MW coal-fired power plant. China National Building Material (CNBM) subsidiary Sinoma Energy Conservation provided engineering, procurement and construction (EPC) services for both power plants.

US: The Portland Cement Association has announced the winners of the Energy Environment Awards 2020. Cementos Argos’ 1.1Mt/yr Harleyville, South Carolina cement plant won the Energy Efficiency Award “by reducing kiln specific heat consumption and increasing the utilisation of the new vertical cement mill,” while CRH subsidiary Ash Grove Cement’s 1.0Mt/yr Midlothian cement plant won the Environmental Performance Award for “operating a whole-tyre burning system utilising a first-in-the-US hot disk system supplied with whole tyres from a nearby tyre recycling company.” Other winners were GCC’s 0.9Mt/yr Odessa, Texas cement plant for Innovation, LafargeHolcim’s 2.2Mt/yr Holly Hill, South Carolina plant for Land Stewardship, Titan Cement's Roanoke Cement Troutville plant for Outreach and HeidelbergCement subsidiary Lehigh Hanson’s 3.2Mt/yr Union Bridge, Maryland plant for Overall Environmental Excellence.

PCA president and chief executive officer (CEO) Michael Ireland said, “America’s cement manufacturers continue to focus on researching and developing new and innovative ways to reduce environmental footprint. The companies receiving these awards are great examples of our industry’s commitment to sustainability and energy efficiency.”

Switzerland: LafargeHolcim has reported sales of Euro5.03bn in the first quarter of 2020, down by 11% year-on-year from Euro5.66bn in the corresponding period of 2019. Cement sales over the period fell by 10% year-on-year to 45.0Mt from 50.0Mt. The group’s earnings before interest and taxation (EBIT) was Euro249m, down by 14% from Euro290m.

LafargeHolcim CEO Jan Jenisch said that the results showed the group’s ‘resilience, despite the COVID-19 outbreak in China’ in January 2020. Other markets were disrupted from mid-March. “I am confident that LafargeHolcim will emerge from this pandemic as an important contributor to economic recovery as building activity gets back to normal,” he added.

LafargeHolcim’s coronavirus action plan consists of a Euro380m year-on-year capex reduction, a Euro285m year-on-year fixed cost reduction, realisation of energy price reductions, a review of all third party products and services and a reduction of net working capital in line with the level of activity.

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.

Sweden: Refractories specialist Höganäs Borgestad opened its new headquarters at Gävle, Gävleborg county on 27 April 2020. The facility will house the Energy and Kiln Engineering, Installation and Management departments.

During the coronavirus lockdown one project of note for Höganäs Borgestad has been refractory maintenance at Germany-based HeidelbergCement subsidiary Norcem’s 1.2Mt/yr Brevik cement plant in Telemark, Norway, for which it supplied 600t of refractories and 45 workers over a three week period.

Taiwan: Asia Cement Corporation has announced its collaboration with Germany-based energy company Innogy on construction of a 448MW wind power plant off Taiwan’s north-west coast near Hsinchu City. Renewables Now has reported that Asia Cement Corporation will supply cement for the project, which will see power sold to the national grid.

Innology, which has participated in the construction of offshore wind plants with a total capacity of 2500MW in Europe, opened its first Taiwan office in 2018.

Japan: Taiheiyo Cement has set out the measures by which it aims to achieve its July 2019 target to ‘reduce net CO₂ emissions per unit of cement production’ by 80% between 2000 and 2050. The measures consist of: the introduction of energy-saving equipment, the promotion of alternative fuels (AFs) and the development of lower-CO₂ cements, accounting for a minimum 15% reduction; development and introduction of new technologies to the production process, targeting especially indirect emissions by modernising energy sources, accounting for a minimum 15% reduction; assumption of future technologies, accounting for a minimum 50% reduction.
