Austria: Unitherm Cemcon has launched the MAS DT rotary kiln burner, a new product in its Mono Airduct System (MAS) product line. The new burner is already in operation at six cement plants in Austria, Germany and France.

The new design uses a more efficient primary air injection, resulting in higher effective momentum and optimised combustion. Placing the adjustable primary air openings directly at the burner tip leads to unobstructed injection of the air jets into the kiln. With minimum losses at the air nozzles, the entrainment of secondary air is improved by approximately 15%.

The new primary air system, with discs instead of flexible hoses, requires less space inside the primary air channel. Therefore, the burner is smaller in diameter and lighter in weight, which reduces investment costs. Unitherm Cemcon says that the cooling of the outer jacket tube with the MAS system (hose and disc design) is superior to that of other rotary kiln burners, as 100% of the primary air is used for cooling. With the new disc system, the cooling of the burner tip is improved even further. The producer added that all new MAS DT burners showed improved lifetime of the refractory lining at the burner. On average the refractory lifetime is extended by approximately 20%.

US: The Environmental Protection Agency (EPA) has awarded Energy Star certification to Buzzi Unicem USA’s plants at Chattanooga in Tennessee, Festus in Missouri, Maryneal in Texas and San Antonio in Texas. This certification is awarded to a facility for superior energy performance in comparison to similar plants. This marks the 10th consecutive year that the Chattanooga, Festus and Maryneal plants have received certification and the fifth consecutive year for the San Antonio plant.

UAE: The shareholders of RAK Cement have approved the conditional of the Newtec cement plant and Al-Banna quarry in Fujairah. The purchase was originally announced in late February 2019. It planned to buy the assets for around US$123m.

More movement in Italy this week with Buzzi Unicem’s purchase of three cement plants from HeidelbergCement. Buzzi acquired the Testi integrated cement plant at Greve and the Borgo San Dalmazzo and Arquata Scrivia grinding plants in Piedmont. No value for the transaction was disclosed but HeidelbergCement trumpeted that it was ‘well on our way’ to reach its target of Euro1.5bn of disposals by the end of 2020. This follows last week’s purchase of Cemitaly's Spoleto cement plant in Perugia by Colacem. Cemitaly, in case readers don’t know, is another of HeidelbergCement’s Italian subsidiaries.

Upon completion of these deals, Buzzi Unicem will own 10 integrated plants and five grinding plants in Italy. It continues the company’s consolidation drive in Italy from mid-2017 when it bought Cementizillo and two of its integrated plants for the knock down price of up to Euro125m.

The two other leading cement producers are now Germany’s HeidelbergCement with its local subsidiaries (led by Italcementi) and Colacem. HeidelbergCement has 10 integrated plants and 10 grinding plant. Colacem has seven integrated plants and one grinding plant. All three companies have integrated production capacities of around 9 – 14Mt/yr. Since 2012 the market has shifted from six major producers to three. Sacci, Cementir and Cemenzillo have left the field following acquisitions by their competitors. Italcementi was taken over by HeidelbergCement in 2016.

Data from the Italian Cement Association (AITEC) shows that the impetus for this consolidation trend was the reduction in Italian cement production to 19.3Mt in 2017 from a high of 47.9Mt in 2006. Despite this though the country still has a total production capacity of 37.7Mt/yr, according to Global Cement Directory 2019 data, giving it an utilisation rate of just over 50%. Production picked up again in the north and central regions of Italy in 2017 but this was insufficient to counter declines in the south and Italy’s islands. Exports have held steady in this time at around 2 – 3Mt/yr but this represents a doubling share of production from 5% in 2006 to 10% in 2017. Production has been steadily dwindling year-on-year since 2006 but domestic consumption rallied a little to 18.7Mt in 2017.

The Italian government instituted its ‘Industry 4.0’ policy in early 2017 to boost competitiveness. This included modest growth forecasts of 1%. International Monetary Fund (IMF) data shows that the country managed gross domestic product (GDP) growth of 0.9% in 2018. Yet, Buzzi Unicem reported like-for-like net sales contraction of 0.9% in 2018. HeidelbergCement was more circumspect in its reporting on Italy for 2018 but it did describe a ‘moderate’ increase in sales volumes of cement excluding its acquisitions.

With the IMF diagnosing the Italian economy as ‘weak’ and cutting its growth forecast to 0.1% in 2019 the prospects aren’t looking encouraging for the cement sector. AITEC data placed cement consumption at 309t/capita in 2017. This is on the low side for Western European standards suggesting that, although more consolidation could be coming, the market may also be down too. Its not great news for cement producers but the Italian market is edging ever closer to recovery.

Russia: Eurocement has appointed Andrey Solovyov as the director general of its 2.6Mt/yr Peterburgtsement plant. Soloviev, a graduate of the Moscow Mining Institute, holds experience working for other cement companies. He previously ran Eurocement’s Sengileevskiy cement plant in Ulyanovsk. He has been suceeded at this site by Ildus Sagitov, a graduate of the Belgorod State Technological University.

Bolivia: SEDEM, the government’s business development agency, has refuted accusations that a new cement plant being built in Caracollo, Oruro does not have enough water or raw materials. Patricia Ballivián, the general manager of SEDEM, presented reports from PricewaterhouseCoopers and C & C Ingeniería y Procesos defending the supplies to the unit. The reports were released in response to accusations by a local politician that the project had been poorly planned.

The reports revealed that the Empresa Publica Productiva Cementos de Bolivia’s (ECEBOL) plant will recycle the industrial portion of its water supply. It will have a supply of 4l/s and a 3.5Ml reservoir. It also has limestone, gypsum and clay reserves sufficient for the production of 100Mt of cement. These are expected to last the plant 60 years.

US: The Portland Cement Association (PCA) has announced the winners of the 2019 Energy and Environment (E&E) Awards. The awards recognised environmental and community relations projects that were completed in 2018 and were presented at the 3rd Annual Cement and Concrete Fly-In.

The CalPortland Mojave cement plant in California won the Energy Efficiency award for the installation of a new classifier system for its vertical roller mill that increased energy efficiency by reducing fan power requirements. The plant also installed a control system for the finish mill that will maximise performance and help reduce wear on equipment. The classifier installation reduced the finish mill energy intensity by 1.5 to 2.0kWh/t, and the control system reduced energy intensity by 13%. In 2018 22% of the electricity consumed by the plant came from on-site renewable wind energy generation. CalPortland has implemented significant energy efficiency measures and its energy management program has been recognised by the Environmental Protection Agency Energy Star program as the Energy Star Partner of the Year for 15 years in a row.

Roanoke Cement Company and Titan America’s Troutville plant in Virginia won the Environmental Performance award for being the first cement manufacturing plant in the US to receive ISO 50001 certification for energy management of all aspects of energy procurement, design and use. The plant reduced its total electrical consumption by 10% and fossil fuels use by more than 12%. The plant has also implemented an alternative fuels program as part of its certification for the True Zero Waste Program, administered by Green Business Certification and has received silver status achieving a 96% rate of waste divergence from landfills.

Lehigh Hanson’s Permanente cement plant at Cupertino in California won the Innovation award for the installation of a water treatment system reducing concentrations of metals, including selenium, to meet permit limits. Lehigh Hanson developed a treatment system that combined ultrafiltration and reverse osmosis (UF/RO) technology in conjunction with biological treatment technology to remove metals, including selenium and dissolved solids. This ensured applicable effluent limits were met while optimising treatment capacity and efficiency. This treatment system is the first of its kind in the cement industry ensuring that effluent limits are met while, at the same time, limiting the quantity of waste needed to be managed.

Buzzi Unicem USA’s Greencastle cement plant in Indiana won the Land Stewardship award for opening a 4km smooth packed stone trail in conjunction with the not-for-profit People Pathways organisation as Phase 2 of the Putnam Nature Trail. Buzzi Unicem USA staff and People Pathways used heavy equipment for rough clearing and grading of the overgrown former railroad bed and improved and expanded the physical trail. These areas were then landscaped with trees, native prairie vegetation plugs, interpretive signage, benches, birdhouses and other features. Additional nature trail enhancements include placement of wildlife monitoring cameras along the trail, installation of nesting boxes and interpretive signage, and maintenance of the recently completed restoration of native flora installed in 2017 and 2018.

Cemex’s Lyons cement plant in Colorado won the Outreach award for volunteering work by its staff at the Rocky Mountain National Park in Boulder, Colorado, performing campground improvement activities at Glacier Basin Campground by moving rocks and fallen timber and clearing existing fire pits of ash deposits. The plant then introduced a new community outreach initiative by hosting a Manufacturing Day event, providing local students tours of the quarry and plant to increase youth interest in pursuing a vocation in skilled trades. Additionally, the plant teamed up with the Celestial Seasonings B Strong Ride for cancer care and research for an event aimed at increasing safety awareness while fundraising for two local organizations and their efforts to fight cancer.

Ivory Coast: Dangote Cement is building a 3Mt/yr cement plant with two production lines from an investment of around US$260m in the Ivory Coast. In an audience with Souleymane Diarrassouba, Minister of Commerce, Industry and Promotion of SMEs, the company said that the project is 70% complete, according to the Agence Ivoirienne de Presse. The new plant will create 800 jobs. It is scheduled to start production in early 2020.

Italy: Buzzi Unicem has purchased the Testi integrated cement plant at Greve and the Borgo San Dalmazzo and Arquata Scrivia grinding plants in Piedmont from HeidelbergCement’s subsidiaries. The enforceable agreement is expected to be completed by the end of July 2019. No value for the deal has been disclosed. Buzzi Unicem said it was making the acquisitions as part of its plan to strengthen its position in the national market.

Germany: Holcim Deutschland’s Kollenbach cement plant in Beckum has commissioned a Zeppelin Cat 6030 FS hydraulic excavator. The machine is 15m long, 7.5m high and it has an engine power of 1500HP. It will mine at least 470t/hr of limestone from the plant’s quarry. The excavator was purchased due to the height and thickness of the marl layers in the deposit. Material from the quarry will then be transported 2.5km by truck to a stationary primary crusher before use at the cement plant.
