Egypt: Helwan Cement has agreed to sell its white cement plant in Minya Governorate to Emmar Industries. The transaction is planned to take place following the de-merger of the white cement unit from the rest of the company. The subsidiary of HeidelbergCement and Suez Cement said that the sale was part of its plan to restructure the business and improve its financial position. The company previously said it had received bid for the white cement plant in June 2018.

Germany: Two workers have in died an accident at a construction site within the HeidelbergCement Schelklingen cement plant, when a 40m-high scaffold collapsed within a silo. Four others were involved, with one slightly injured. All six operatives had entered the silo from the top. Spokesperson Elke Schönig said that the scaffolding had become ‘staggered’ for unknown reasons and then partially collapsed. The incident will be investigated.

Benin: HeidelbergCement’s subsidiary Cimbenin has removed two polychlorinated biphenyl (PCB) transformers from its grinding plant in Cotonou. The toxic components will be disposed of by a French company, according to the La Nation newspaper. The Société Nationale de Ciment (SONACI) installed the transformers in 1977. Subsequently Cimbenin bought the unit in 1991 and put the affected equipment into storage in 2012. The decision to remove the transformers was part of the company’s ISO 14001-2004 certification, which it obtained in 2012.

Italy: Cemitaly has been allowed to use slag and ash in cement production at its Taranto plant following an investigation, according to the Il Fatto Quotidiano newspaper. The former Cementir unit was investigated in 2017 as part of an illegal waste probe that examined whether the Taranto plant purchased ‘illegal’ by-products from Enel and the ILVA steel plant to produce cement.

Germany: HeidelbergCement’s revenue from its cement business fell by 2.5% year-on-year to Euro4.16bn in the first half of 2018 from Euro4.27bn in the same period in 2017. Despite this, its cement sales volumes grew by 3% to 61.9Mt from 60.1Mt due to growth in its Asia-Pacific and Africa-Eastern Mediterranean Basin, Northern and Eastern Europe-Central Asia areas. Across all business lines its sales revenue rose slightly to Euro8.43bn from Euro8.39bn although the group said it rose by 6% on a like-for-like basis. Its profit increased by 20.2% to Euro435m from Euro362m.

“The growth of revenue and sales volumes in all business lines reflects the strong market dynamics. All in all, we could significantly improve the profit also in the second quarter. The strong operational development, lower restructuring charges and a further reduction in financing costs more than compensated for the increasing cost inflation and negative exchange rate effects,” said Bernd Scheifele, chairman of the managing board. He added that a ‘solid’ development of results in the second quarter indicated a positive trend reversal after a weather-related difficult start of the year.

By region, in Western and Southern Europe the group’s cement and clinker sales volumes rose by 5.3% to 15.1Mt due to the acquisition of Cementir in Italy and the good development of sales volumes in Spain. In its Northern and Eastern Europe-Central Asia area, sales volumes fell by 4% to 11.5Mt due to bad weather. In North America its sales volumes decreased by 2.3% to 7.4Mt due to bad weather and the sale of its white cement business. In Asia-Pacific sales volumes rose by 5.4% to 17.5Mt with growth noted in Indonesia. Finally, in the group’s Africa-Eastern Mediterranean Basin area sales volumes grew by 6.4% to 9.9Mt driven by markets in Sub-Saharan Africa.

Earlier this year South Africa’s PPC commented on the drought facing Cape Town. It said that cement manufacturing was not water intensive, that its operations were ‘totally’ self-sufficient from its own surface water sources with capacity for several months and that it was working with the local government which viewed construction as an important economic sector. Point made!

Water conservation is an established part of the sustainability toolkit for cement producers. Yet recent weather patterns in the Northern Hemisphere may also test how well companies are doing. Above average temperatures have been recorded this summer, in some places accompanied by unusually dry conditions. A news story this week about Cemex Colombia being fined for using water from a river shows one aspect of the problems that can face industrial users. Another story that we’ve covered previously has been the legal action taken against producers using water from a site near to the Katas Raj Temples in Pakistan.

Wet process cement manufacturing uses more water than dry process but even modern plants use water for cooling equipment and exhaust gases, in emission control systems such as wet scrubbers. In addition, quarrying and aggregate production may require water, and concrete production also needs water. Issues also arise with quarry dewatering and discharging water into rivers and the like. Global Cement Directory 2018 data indicates that, where known, about 10% of integrated cement plants still use a wet production method.

As Graph 1 shows there is some variation between the major cement producers with regards to how much water they use. They all operate with different types of equipment and production methods in different geographical locations so the difference between the companies is to be expected. A cement plant in northern Europe that normally experiences high levels of rainfall will have a different approach to water conservation than one, say, in a water stressed area like the Middle East. Incidentally, the definition used to define a water-stressed or scarce area is one where there is less than 1000m³/yr per person. One other point to note here is that each of the companies has a higher consumption figure than the 100 – 200L/t that the Cement Manufacturers' Association of the Philippines (CeMAP) reckoned that an average dry-process cement plant used when it was promoting water conservation back in 2013.

Looking at specific recent success stories, India’s UltraTech Cement reported a specific water consumption of 54L/t of clinker at its Star Cement plant in Dubai, UAE in 2016 – 2017 following a dedicated initiative at the site. An another milestone that UltraTech Cement was keen to point out in its last sustainability report was that three of 13 integrated plants had achieved water sufficiency though the use of the company’s 360° Water Management Model with its use of rainwater harvesting and recharging groundwater. These plants are not dependent on any groundwater or fresh water sources. The other larger cement producers all have similar water management schemes with reduction targets in place.

Climate change models generally predict hotter and wetter weather but changing weather patterns and growing populations are likely to impact upon water management and consumption. Given the integral nature of water in the cement production process, many cement producers have realised the importance of it and treat it as an input material like fuel or limestone. Hence the highlighting of water conservation in company sustainability reports over the last decade. The test for the success of these initiatives will be how producers cope in drought situations where they may be seen as being in competition with domestic users. Thankfully in PPC’s case, Cape Town avoided having to ration water to the general public, as the rains returned in the spring.

Italy: Italcementi plans to keep the Arquata Scrivia grinding plant open. The assurance was given to union representatives following worker redundancies at the unit, according to Alessandria News. The subsidiary of Germany’s HeidelbergCement competed its purchase of the plant from Cementir Italia in January 2018. It has since been rebranded under the Cemitaly brand.

Georgia: HeidelbergCement Georgia plans to close a kiln at its Rustavi cement plant due to imports from Iran. It will also reduce production at the Dedoplitskaro limestone quarry, according to GBC Daily News. The Georgian Cement Association has lobbied the government to enact anti-dumping measures against Iranian imports.

US: Lehigh Hanson’s Speed cement plant in Indiana will be converted into a distribution terminal. The decision follows an investment of US$600m towards upgrading the Mitchell cement plant in Indiana, according to the Evening News and Tribune newspaper. At present the Speed plant has a cement production capacity of 1Mt/yr and the Mitchell plant has a production capacity of 0.7Mt/yr. Following the upgrade the Mitchell plant will have a capacity of 2.8Mt/yr. Changing the focus of the Speed unit is expected to lead to the loss of 100 jobs. although half of these could be moved to Mitchell.

Italy: HeidelbergCement’s subsidiary Italcementi has rebranded CementirSacci and Cementir Italia as Italsacci and Cemitaly respectively. The move follows the integration of the companies into the group at the start of 2018.

The cement producers operate four integrated plants and two grinding plants. Italsacci runs plants at Tavernola Bergamasca, Greve and Cagnano Amiterno. Cemitaly runs plants at Spoleto, Arquata Scrivia and Taranto.

Italcementi now operates 10 integrated plants, one plant for special projects, 10 cement grinding plants, 113 concrete plants and 13 aggregate quarries in Italy. Its headquarters is based in Bergamo.
