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 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.

Egypt: Sinai Cement’s net loss in 2019 was US$28.1m, down by 44% year-on-year from US$50.2m in 2018. Arab Finance News reported that the company attributed the loss to accumulated effects of currency devaluation on imported fuel and to rises of electricity and oil prices.

US: Italy-based Buzzi-Unicem subsidiary Alamo Cement Company has signed a contract with Italy-based renewable power supply expert Renergetica for the construction of a solar power plant at its 1.1Mt/yr integrated Plant 1604 cement plant in San Antonio, Texas. Renewables Now News has reported that the plant will have a capacity of 10MW.

US: The Environmental Protection Agency (EPA) has awarded Energy Star certification to Japan-based Taiheiyo Cement subsidiary CalPortland’s 1.3Mt/yr integrated Rillito plant for the eighth consecutive year for its superior energy performance compared with other plants of comparable capacity in the country. CalPortland president and CEO Allen Hamblen said, “We continue to demonstrate our commitment to environmental stewardship and ENERGY STAR while also reducing our energy costs through the hard work of our employees and our corporate energy management culture.”

France: Hoffman Green Cement Technologies, a pioneer in low-carbon cement production, has announced the publication of its Life Cycle Inventories (LCI) in the INIES database, France’s national reference database for environmental and health performance in the construction sector.

The LCI published by Hoffmann Green summarises all incoming and outgoing flows of raw materials and energy resources used to manufacture its H-UKR and H-EVA cements to allow an assessment of the environmental impacts. They will serve as input data for the software that carries out the life cycle analysis of a construction product, often comprising several materials.

H-UKR is a binder that is based on alkali-activated blast furnace slag, which is sold into the precast concrete, ready-mix concrete and bagged cement markets. H-EVA is a high ettringite binder that is used in the mortar, coatings, road binder and ready-mixed concrete markets.

Julien Blanchard and David Hoffmann, the company’s founder’s stated, "The publication of the LCI of our cements is a first in France and is part of our determined ambition to decarbonise the construction sector and be fully transparent vis-à-vis all our stakeholders. It also illustrates our commitment in the face of the climate change emergency and the need to reconcile cement and the environment.”
