Update on water conservation
25 July 2018Earlier 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.
Colombia: Cemex Colombia has been fined US$429,000 for taking groundwater from the Tunjuelo River without permission. The sanction of the District Department of the Environment of Bogotá imposed the penalty, according to the La Republica newspaper. However, the settlement exonerated Cemex of causing any environmental damage. The company says it does not plan to file any legal appeal for the sanction.
Mexico: The Procuraduría Federal de Protección al Ambiente (PROFEPA) awarded an Recognition of Environmental Excellence to 12 Cemex cement plants. The award is presented to companies that demonstrate a continuous commitment to protect the environment. The plants that were recognised were: Atotonilco in Hidalgo; Barrientos in Mexico State; Ensenada in Baja California; Huichapan in Hidalgo; Mérida, in Yucatan; Monterrey in Nuevo León; Tamuín in San Luis Potosí; Tepeaca in Puebla; Torreón, in Coahuila; Valles in San Luis Potosí; Yaqui, in Sonora; and Zapotiltic, in Jalisco.
Colombia: Édgar Ramírez Martínez, the former vice president of planning for Cemex, will be detained in prison as part of an ongoing investigation into alleged irregularities in the acquisition of land at Maceo in Antioquia for the construction of a cement plant. The prosecutor’s court has also issued a detention ticket for Camilo González Téllez, former vice president of planning for Cemex Colombia, who is currently in the US, according to Noticias Financieras. Eugenio Correa Díaz, the former representative of CI Calizas y Minerales, which sold the property to the cement producer, will also be detained.
The former employees of Cemex allegedly paid over US$13m to Correa, despite being aware of the fact that the property was in the process of being expropriated over unpaid taxes.
Colombia: Cemex Colombia, LG and the mayor of Ibague say that they have started technical economic and legal studies studies to support building a solar plant near Ibague in Tolima. The unit will supply energy to the Caracolito cement plant and lighting systems in the nearby city, according to Valora Analitik. The solar plant will be located on a 56-hecatre site owned by the Mayor’s Office on the Doima - Buenos Aires highway.
Cemex Colombia to grow additives production in 2018
29 June 2018Colombia: Cemex Colombia plans to grow its additives production to 9.7ML in 2018. The building materials producer says it is the only local manufacturer of producing aggregate, cement and additives, according to the La Republica newspaper. It produces additives to enhance the properties of cement and concrete. It also supplies additives to other companies with around 11% aimed at third parties in Latin America.
Taking the industry pulse at Hillhead 2018
26 June 2018Hillhead 2018 is on this week and where better to capture a feel of the UK’s quarrying and construction industries? For those that don’t know, Hillhead is a biennial show that takes place in a quarry in Derbyshire. The show bills itself as the largest quarrying, construction and recycling event in the world. A large scale UK show gives us the opportunity to look at the local cement industry and we did exactly that in the June 2018 issue of Global Cement Magazine with Edwin Trout’s feature on the UK cement sector in 2017 and 2018. Following on from that article we’ll pick up a few threads.

Cement production in the UK fell by 5Mt/yr during the financial crisis of 2007 - 2008. Since then, as Graph 1 shows, production has been growing almost uniformly. However, it may have reached a plateau in 2017, with the major producers complaining about a weakened market due to Brexit uncertainty.
Main points from a news angle are the rise of the Breedon Group with its acquisition of Ireland’s Lagan Cement in April 2018, investments at Hanson’s Padeswood cement plant and Tarmac’s Dunbar cement plant and a fairly static market reported by the major producers. Alongside this, Ireland’s Ecocem opened a terminal in Sheerness in June 2017 and, more recently, has just inaugurated its slag grinding plant on the other side of the English Channel at Dunkirk.
The decision by Breedon to straddle an impending UK-European Union (EU) border seems wise with Hanson’s parent company HeidelbergCement actively blaming Brexit for market uncertainty in the UK. The rise of Ecocem, a slag cement grinder and distributor, also seems to suit the atmosphere with its smaller, more nimble operation than a clinker producer. It’s into this situation that Hanson is reusing a mill from Spain for its Padeswood project and Tarmac is buying its mill from Cemengal, a manufacturer known for making modular mills that can be moved after installation if so desired.
Banging on about Brexit, and indeed Brexit uncertainty, can’t last forever and once clarity appears then the building industry can focus on various pressing issues. One is the country’s lack of residential housing supply. One possible solution for this is a new national planning policy. The government finished a consultation period in May 2018 for the National Planning Policy Framework (NPPF) and industry bodies like the Mineral Products Association (MPA) have been making their views known. The MPA worries that that the proposed changes will weaken the mineral planning system and threaten the replenishment of aggregate and other mineral reserves. It argues that to secure the essential minerals required to build all those new houses the government needs an, “...efficient and effective mineral planning system with up to date plans, well-resourced planning departments and good data, which are prerequisites, as is appropriate capacity and capability in the ministry to ensure the system is planned, monitored and managed.” Detractors may point out that once the NPPF gets sorted we can all get on with the job of actually, like, building things but, as ever, the MPA has its part to play in the process.
Another indicator for the resumption of ‘business as normal’ might be the number of exhibitors at a trade show like Hillhead. The oranisers say that the exhibitors have grown by 10% in 2018 from 2016. With a heatwave forecast, the group stages of the football World Cup continuing and live demonstrations ongoing there are worse places to be to ponder the state of the industry. Come and find Global Cement at our stand (PC45) in the main pavillion at Hillhead 2018 and tell us what you think.
Council of State confirms fine for Holcim Colombia
25 June 2018Colombia: The Council of State has confirmed a US$0.31m fine to Holcim Colombia imposed by the Superintendent of Industry and Commerce (SIC) for fixing the price of cement. The ruling follows a similar confirmation of a fine to Cemex. The court found that an agreement between Cemex Colombia, Holcim Colombia and Cementos Argos distorted the price, supply and sales of Ordinary Portland Cement in the second half of 2005.

The ruling found that an agreement between Cemex Colombia, Holcim Colombia and Cementos Argos distorted the price, supply and sales of Ordinary Portland Cement in the second half of 2005. In particular the tribunal found that the way in which Argos gave information about Cementos Andino’s involvement in the national market to Cemex and Holcim was be anti-competitive.
Cemex UK to move to new headquarters in Rugby
20 June 2018UK: Cemex UK will move its headquarters from Thorpe, Surrey to its offices in Rugby, Warwickshire from 1 July 2018. The new premises were the former global head offices for the Rugby Group until 2000. To date the Rugby offices have provided a regional centre for the company. From July 2018 the senior leadership team and all back-office functions such as taxation, communications and human resources will be based at Rugby, working alongside business areas such as the national customer service centre, Marketing and logistics.
“Rugby lies geographically at the centre of our UK business and with changing patterns of working such as increased working from home and from operational sites, it makes good business sense to consolidate our offices. Rugby and the Rugby brand are at the ‘heart’ of our business and the creation of the new headquarters will ensure greater efficiency and communication,” said Michel Andre, Country President, Cemex UK.
