Egypt: Wikov hosted its Wikov Gear Technology Conference in Cairo in late October 2019 to promote its products to cement producers in the Middle East. The focus was on the historical presence of Wikov in the market under the former brand Škoda, and later the product highlights and innovations like Side Drive gearboxes with Separate Lubrication System and shock-load-resistant planetary gearboxes Orbi-fleX with flexible pin. The conference also included a demonstration of Wikov’s new online gearbox configurator. This platform enables users to configure and select a planetary gearbox, generate technical data, a 3D model and send a request for quotation. Around 70 industry delegates attended the event.

US: Global Cement is exhibiting at the 36th International Cement Seminar & Exhibition taking place in Atlanta, Georgia. The long running cement equipment and technology event has returned after a lengthy break. Portland Cement Association (PCA) chief economist Ed Sullivan gave the keynote address at the conference with an industry forecast for 2020.

There were two main takeaways from the Global Future Cement Conference that took place in Brussels last week. Firstly, there are not any obvious alternatives to using cement and concrete. Secondly, serious at-scale commercial investment on capturing CO₂ process emissions from clinker production is still waiting for the right economic conditions.

Although the conference was heavily focused on Europe, the graph above explains why the cement and concrete industries are sitting pretty right now in the face of mounting environmental activism. The sector may be responsible for 5 - 10% of annual CO₂ emissions but, put bluntly, there is simply no alternative. As Karen Scrivner from the Ecole Polytechnique Fédérale de Lausanne (EPFL) explained during her presentation, concrete uses some of the most abundant minerals present on earth, notably silicon and calcium. Alternative chemistries are simply not backed up by available materials. The cement and concrete associations have strongly promoted the unique position by focusing on the whole lifecycle of building materials.

The energy and emissions research needs to be scrutinised much more closely but, if it’s correct, there is no way to maintain modern standards of living without concrete. And, judging from the response by the French public to a badly handled meagre carbon tax on diesel by the so-called Yellow Vest movement, whacking up the price of housing or infrastructure might go down badly, especially in developing countries.

Two immediate ‘outs’ presents themselves. Cement doesn't necessarily have to be made from clinker as Robert McCaffrey’s presentation reinforced (also given at the IEEE/IAS-PCA Cement Conference this year). Future research may find alternatives to clinker and wipe out the cement business in the process. Also, the graph above is based on per kilogramme amounts of each building material. It doesn’t indicate how much of each material is required to build things. Even if clinker-based building materials are irreplaceable, there is no reason why their market share might not decrease. This could have large consequences in a market already burdened by over-capacity.

Solid research into carbon capture technology is proceeding apace, from the LEILAC project at HeidelbergCement’s Lixhe plant, to oxyfuel kiln development and other methods, as Jan Theulen from HeidelbergCement demonstrated in his presentation. Off-the-shelf technologies from other industries also exist ready to be used. Today, for example, Inventys has announced plans to test its own CO₂ capture technology with Lafarge Canada. Yet there are no commercial-scale installations in Europe. most likely due to the price burden it would place on the end product.

With the European Union (EU) Emissions Trading Scheme (ETS) entering its fourth phase and the carbon price holding above Euro20/t the question is: when will the serious investment begin in Europe? Notably, more than a few major European cement equipment manufacturers attended the Global Future Cement Conference, yet none are offering mature products to capture CO₂ emissions. Most or all have projects up their sleeves ready to be developed and sold but orders aren’t being received. The carbon price in Europe is the problem here. If it's too low then nothing happens outside of government subsidy. Too high and cement plants start being shut down because they become too expensive to run. To be fair to the cement sector other carbon emission mitigation strategies are being employed from alternative fuels usage to lowering the clinker factor and other methods but the endgame is based on reducing process emissions.

The challenge for the cement and concrete industry is to show legislators that their materials are essential and irreplaceable. They are doing this. The legislators then need to concoct ways of encouraging mass scale rollout of carbon emissions abatement technology without destroying the cement industry. This is far from certain right now. If nothing else it’s in governments’ interest to get this right because, as the Yellow Vest protests show, if they get it wrong their voters become angry. All of this is happening against the clock as CCU/S is required to get the cement industry past the 2050 2°C maximum warming target set by the Paris Agreement. In the meantime the cement industry is essentially in a holding position on the more far-reaching aspects of CO₂ emissions mitigation. Its products are likely irreplaceable but its carbon capture technology has to be encouraged by governments. This means that, for most cement producers, waiting to see what happens next is the way forward.

The 3rd Future Cement Conference and Exhibition is scheduled to take place in Vienna, Austria in 2021

US: Robert McCaffrey, the editorial director of Global Cement, has presented ‘The global cement industry in 2050’ at the 61st IEEE-IAS/PCA Cement Technical Conference 2019 taking place at St Louis in Missouri. The presentation used data from a variety of sources to explore how the cement and concrete industries could look in 2050 including shifts in societies, demographics, technologies, business and the environment.

India: Germany’s Gebr. Pfeiffer has hosted a customer event for the Indian cement industry at Gurugram near New Delhi. The two-day event in late November 2018 consisted of specialist talks on mineral processing. The equipment producer covered 3D system design, optimising grinding processes, after sales service strategies and other industrial sectors that intersect with the cement industry.

Germany: Christian Knell, the president of the German Cement Works Association (VDZ), has warned that meeting climate change goals was leading to ‘considerable’ costs for the cement industry. He said that ‘suitable boundary conditions would have to be created’ for climate change issues and noted that on-going trends in European emissions trading and the ‘rapidly’ increasing price of CO2 were leading to mounting costs. “To be able to realise our efforts in terms of climate protection and at the same time not lose competitiveness, we need research policy-related support for our investment in breakthrough technologies and the corresponding demonstration projects,” said Knell.

Knell made the comments during the opening ceremony of the 8th International VDZ Congress 2018 in Duesseldorf. He identified climate protection and digitalisation as key issues for the future of the industry.

There is lots to mull over for the cement industry from last week’s Global Slag Conference that took place in Prague.

One striking map from Michael Connolly, TMS International, showed the status of slag and steel products in the US. It was a multi-coloured patchwork of different regulatory statuses from approval to be used as a product to regulatory exclusion. This won’t come as a surprise to many readers but even within one country the way slag can be used legally varies.

As this column reported last year after the Euroslag Conference, the European Union can be presented in a similar way. The irony here is that increased use of slag and other secondary cementitious materials (SCM) is exactly the kind of change the cement and concrete industries need to make to decrease their carbon emissions. Constant quibbles over whether slag is a product or a waste undermine this. Happily then that Connolly was able to report progress in the US as lobbying by industry and the US National Slag Association have led to more states legally accepting slag as a product.

However, cement producers have other concerns in addition to environmental ones when it comes to slag usage as Doug Haynes from Smithers Apex explained. Haynes, a former UK steel industry worker turned consultant, spoke around a market report on the future of ferrous slag. His take on Basic Oxygen Furnace (BOF) slag was that despite fuel savings, decreased CO₂ emissions and the benefits of embodied iron when it is used as a raw material for clinker production, it is in the interests of cement producers for slag to be a waste because they then get it for free or at a reduced rate. It’s a similar story to the use of waste-derived fuels powering cement plant kilns where producers want lower fuel costs but waste collectors want value for their product. Unsurprisingly, Haynes wanted cement producers to accept the value embodied in BOF slag.

Charles Zeynel of ZAG International, an SCM trader, then laid out the situation where global SCM supplies are remaining static but cement demand is growing. Coal-fired power station closures are reducing supplies of fly ash, another SCM, placing pressure on existing granulated blast furnace slag (GBS) slag supplies. The message was very much in a slag trader’s favour but instructive nethertheless. If slag is in demand then the price will rise. Anecdotally, the increased number of cement producers at the conference seemed to indicate increased interest of the cement industry in the product.

Lots more speakers followed on topics such as slag beneficiation, grinding advances and new innovations. On grinding, one surprise that popped up was that Spain’s Cemengal has sold a Plug & Grind Vertical mill to CRH Tarmac’s cement plant at Dunbar in Scotland. It is the first such sale of this product in Europe. The last speaker, Jürgen Haunstetter of the German Aerospace Centre, stuck out particularly with his presentation on using slag as a thermal energy storage medium in a concentrated solar power (CSP) plant. This may not seem connected to the cement industry but it is along similar lines to Italcementi’s project at the Aït Baha cement plant in Morocco, which uses a CSP process that can be used with the plant’s waste heat recovery unit.

The Global Slag Conference will return in April 2019 in Aachen, Germany.
