Pakistan: Bestway Cement has promoted its environmental credentials following the Supreme Court’s mandated investigation into water usage by cement companies near the Katas Raj Temples in 2018. The cement producer says that all of its cement plants are ISO 14001:2004 Environment Management Systems certified. Specifically on the issue of water conservation, it has installed air-cooled condenser systems at two of its plants at Chakwal and Kallar Kahar respectively and it has built rain-harvesting ponds. In total the company has spent around US$14m on water conservation measures. Altogether it says that it has achieved 80% and 88% reductions in consumption of ground water for industrial use, respectively, at the two plants.

Other environmental measures the company has made include installing waste heat recovery (WHR) units at all four of its cement plants. Its total WHR capacity is 45.5MW giving it 28% of its total power needs. The company is recognised by the United Nations Framework Convention on Climate Change (UNFCCC) under its Clean Development Mechanism (CDM) Program for its initiative to reduce carbon emissions/footprint. It has also implemented tree plantation at its plants and surrounding areas, it uses drip irrigation and sewerage waste management and its head office in Islamabad has been certified as a Green Office by the World Wide Fund for Nature (WWF).

Chief executives from over 30 companies attended the Global Cement and Concrete Association (GCCA) inaugural event last week in London. Its first president Albert Manifold, the chief executive officer (CEO) of CRH, laid out the line by saying that, “For the first time we have a global advocacy body.” He followed this up by emphasising that ‘our product’ is the most used man-made product in the world. Just like the Cement Sustainability Initiative (CSI), the body the GCCA is partly-replacing, it is a CEO-led organisation. The target is very much about giving a global voice to the cement and concrete industries and the vertically integrated companies that produce these products.

Along with the head of CRH, the leaders of LafargeHolcim, HeidelbergCement, CNBM, Votorantim, Buzzi Unicem and Eurocement, amongst others, were all on the attendance list too. That kind of representation gave the event a charged air and a real sense of intent. At present the association says it represents 35% of global cement production and its aim is to reach 50%. That compares to the 30% base that the CSI had.

Representatives from some major cement associations were also present, including Europe’s Cembureau, the Federación Interamericana del Cemento (FICEM), the Canadian Cement Association and the VDZ. The only thing stopping the US Portland Cement Association being there was reportedly the Thanksgiving holiday. Although not comprehensive, that kind of representation suggests serious interest from the regional cement associations. The word from the GCCA CEO Benjamin Sporton was that the GCCA is here to provide a global level of coordination to the advocacy and sustainability side of the industry dealing with global organisations like the United Nations (UN), development banks, other associations and non-government organisations (NGOs).

How this will work in practice has yet to be seen, but at the very least, the GCCA can take over the work of the CSI and run with it. The word from the attendees we spoke to was uniformly positive for the association. It was seen as a long-overdue move to finally give the industry some sort of uniform voice at a global scale. In this sense it is catching up with similar bodies in industries like wood and steel. One benefit from moving from the CSI to a full advocacy organisation is that the industry can actually talk about the good things it does rather than being limited to sustainability and environmental data reporting. It seems like a small change in focus but it’s a big shift in mind-set.

A cynic might suggest that the exercise is one of a dirty industry trying to wrest the Overton window, or window of public discourse, back from legislators facing mounting environmental pressure. The latest UN Emissions Gap Report for 2018, for example, reported this week that CO₂ emissions rose in 2017 after four consecutive years of decline. This is the latest environmental report in a long line pointing out bad news. Yet, the GCCA’s unwritten mantra, that concrete improves lives, is sound. Somebody or something needs to link it all up. That somebody might just be the GCCA.

A review of the inaugural annual general meeting and symposium of the GCCA will be published in a forthcoming issue of Global Cement Magazine.

Spain: FYM-HeidelbergCement has launched a sustainability commission to support its Malaga cement plant and the surrounding community. The initiative is part of the company’s 2030 sustainability plan. It includes representatives from local neighbourhood associations, local government and environmental bodies. The commission will meet several times a year to foster an open relationship between the cement producer and its neighbours. It also intends to promote behavior based on the circular economy and the reduction of the unit’s carbon footprint. It will build on the company’s work with the Provincial Forum of Socially Responsible Companies of Malaga since its inception in 2013.

Denmark: Engineering company FLSmidth is working with insulation manufacturer Rockwool and the Technical University of Denmark (DTU) on a research project to develop sustainable process technologies that will increase the use of renewable fuels and raw materials and reduce CO₂ emissions. The project has received a Euro2.7m grant from Innovation Fund Denmark.

The project plans to investigate and optimise high-temperature processes throughout the entire production chain in both companies. The DTU holds experience in this field from the CHEC research centre at DTU Chemical Engineering, which has focused on combustion research and emission abatement in recent years. FLSmidth plans to explore using alternative cement formulas and production methods to enable the company to launch more efficient technologies for using renewable fuels and reducing emissions. Rockwool intends to lower CO₂ emissions and reduce its fuel consumption to make its production become more sustainable.

Japan: Taiheiyo Cement has been selected to be part of the Dow Jones Sustainability Asia Pacific Index for the fifth consecutive year. The company was first chosen in 2014. The index is the Asia Pacific version of the Dow
Jones Sustainability Indices and it serves as a benchmarks for socially responsible investment.

Colombia: Cementos Argos has been ratified for the sixth consecutive year as a member of the Dow Jones Sustainability Index (DJSI), which recognises good practices in terms of economic, environmental and social sustainability of the companies registered in stock markets. Celsia, a Grupo Argos energy subsidiary, was also included in the Dow Jones Sustainability Index for the Latin American Integrated Market (MILA) - Pacific Alliance, which recognises companies with the best economic, social and environmental practices in Chile, Peru, Mexico and Colombia. Grupo Argos and Cementos Argos were also included.

"Being ratified as world leaders in sustainability by Dow Jones is the result of our conscious investment, our commitment to a responsible operation of all our businesses, and our permanent interest to positively impact society, respecting our planet," said Jorge Mario Velasquez, chief executive officer (CEO) of Grupo Argos.

In 2018 more than 3500 companies around the world were invited to participate, but only 317 were selected as members of the worldwide DJSI.

The Global Cement and Concrete Association (GCCA) announced this week that it intends to take over the work done by the Cement Sustainability Initiative (CSI). This marks a change in how the cement industry as a whole approaches sustainability and in the wider context how the sector manages itself on the world stage.

The CSI was set up in 1999 with the aim of advancing a sustainability agenda for the cement industry. It has done this by laying out strategy for the industry to follow in the form of technology roadmaps and publishing its ‘Getting the Numbers Right’ (GNR) data on CO₂ and energy performance information. By 2018 it had 24 cement company members composed of nine core members, 14 participating members and one affiliate member. It represents around 2.4Bnt/yr of global cement production capacity or over half of the world production, according to Global Cement Directory 2018 data.

The idea behind the membership was that the core members are all members of the World Business Council for Sustainable Development (WBCSD) and that the members would contribute ‘modest’ funds to run the organisation. That last point about WBCSD membership is worth noting because members need to stick to conditions such as publishing an annual sustainability report and agree to have the sustainability report reviewed and benchmarked by the WBCSD.

The GCCA, which formed in early 2018, says it had formed a ‘strategic’ partnership with the WBCSD and that it will take over the work previously done by the CSI from the start of 2019. Although there’s no mention so far whether GCCA members have to actually become WBCSD members with all that this entails. At present the GCCA consists of nine major international cement producers, including over half of the world’s top 10 producers by production capacity, with a production base in every inhabited continent except Antarctica. Roughly speaking it represents just under 2Bnt/yr of global cement production capacity or about half of the world’s total.

Now where this starts to get confusing is that other cement associations exist with their own established advocacy roles and sustainability agendas. The established players include the various regional associations such as the Portland Cement Association in the US, Cembureau in Europe and so forth. The multinational ones also often represent national bodies.

Then there is the World Cement Association (WCA), which formed in 2016. This independent body is a private company run out of an office in London, UK with non-profit aims. It has 45 members but only three quarters are actual cement producers. Of these most are single-country cement manufacturers. The glaring standout is China National Building Material (CNBM) and its subsidiaries, representing over half of the association’s member’s cement production capacity. The production capacity of the WCA’s members is around 1Bnt/yr or a quarter of the global total. More than half of this comes from CNBM and its subsidiaries. Unsurprisingly then that Song Zhi Ping, the head of CNBM, is the president of the WCA. It too supports a sustainability agenda, saying that it, “seeks to co-operate with the WBCSD, CSI and regional and national Cement Associations.” What is noteworthy is how few of the current members of the WCA joined the CSI previously.

There is definitely a need for a global organisation advocating sustainability issues for the cement industry and by taking over the work of the CSI and the GCCA has cornered this part of what a global cement association might do. However, the GCCA represents less cement production capacity than the CSI did. The main omissions are the Indian producers, led by UltraTech Cement, as well as others. It seems likely that they will join the GCCA following the end of the CSI but there is no guarantee.

The other point arises when looking at these various cement associations is: who does what exactly? The CSI’s focus on sustainability gave it a purpose that it did well with a genuine appearance of independence. Its narrow focus also gave it a complimentary role to the existing national and regional associations. Global bodies like the GCCA and the WCA are clearly more into advocacy territory for their members. Also, a more general association approach like the GCCA and the WCA may clash with regional bodies like the PCA and Cembureau. Regional bodies seem better suited to the way governance works globally with regional groups such as the European Union (EU) or government departments in continental sized countries such as the US, China and India. However, a truly global cement body could respond better to coordinated environmental lobbying and fill in the gaps around the world in places with looser regional representation.

Sustainability is the immediate link between the CSI, the GCCA and the WCA. Indeed the WCA recently held a ‘Global Climate Change’ forum in Paris to discuss its own climate action plan. Yet, with the GCCA taking over the work the CSI does and the WCA saying it wants to cooperate with the CSI, the obvious outcome is that the GCCA will become the world’s apex cement association. It will represent the companies with the most cement production capacity, have a presence in every inhabited continent and take the lead on WBCSD issues. Beyond this though it will be interesting to see what, if anything else, the GCCA chooses to do.

Germany: Holcim Germany’s Beckum cement plant has gained a silver sustainability certificate from the Concrete Sustainability Council (CSC). The company said that certificate is the highest that a cement plant can obtain. It certifies that the plant promotes transparency about the production process and supply chain as well as considering its impact upon the environment.

The company said that the unit is the first LafargeHolcim cement plant in the world to have CSC certification. It also plans to certify cement grinding plants and ready mix plants in Germany in the near future.

UK: The Global Cement and Concrete Association (GCCA) has formed a strategic partnership with the World Business Council for Sustainable Development (WBCSD) to facilitate sustainable development of the cement and concrete sectors. As part of the new agreement, the work carried out by the Cement Sustainability Initiative (CSI) will transfer from WBCSD to the GCCA on 1 January 2019 with activities managed out of the GCCA’s London offices. The new partnership will also create synergies between work programmes to benefit both the GCCA and WBCSD and their respective member companies.

“Transferring the activities of the CSI to the GCCA is a logical step and further underlines the cement and concrete sector’s commitment to advance sustainable development across the construction cycle. As the authoritative worldwide voice of the cement and concrete sector, the GCCA is ideally placed to take this work to the next level, building on the strong foundations established by WBCSD,” said Albert Manifold, chief executive officer (CEO) of CRH and GCCA President.

The CSI, which was established in 1999 and currently operates under the auspices of WBCSD, is a global effort by 24 major cement producers to advance sustainable development. Over its 19-year history, the CSI has focused on understanding, measuring, managing and minimising the impacts of cement production and use by addressing a range of issues including: climate change, fuel use, employee health and safety, airborne emissions, concrete recycling and quarry management.

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.
