India: A reduction in government spending and delays to the release of state funds ahead of India’s general election led to a slowdown in Indian cement demand growth in April and May 2019. Growth in cement consumption is expected to fall to a seven quarter low in the quarter to 30 June 2019.

“Pan-India cement demand will post muted 3-5% growth in the current quarter (the first quarter of the 2020 Fiscal Year), with states in the East (Bihar, Odisha) and South (Andhra Pradesh and Telangana and Tamil Nadu) moving at a snail's pace of 2-4%," said Hetal Gandhi, director at Crisil Research. However, Crisil expects demand to pick up in the second half of the 2020 fiscal year, with growth 6.0-7.5% for the 12 months to 31 March 2020 as a whole.

India: Ramco Cements has launched a new premium blended cement, Ramco Supercrete. The company says that Ramco Supercrete is packed in Biaxially Oriented Polypropylene bags (BOPP) bags to ensure no spillage and thus ensure a cleaner environment. Ramco Supercrete will be targeted at the ‘premium’ section of the cement market.

Ramco Cement also reports that it has invested US$500m in various expansions that are underway. The company's new capacity in West Bengal is already on stream. The company's Odisha plant is expected to be commissioned by October 2019, its Vizag plant expansion will be completed by December 2019, its Jayanthipuram expansion by July 2020 and work on its Kurnool plant will be finished by March 2021.

Honduras: Colombia’s Ultracem plans to build a new cement grinding plant in Cortés, Honduras. At present the company has invested US$2m in the country and it employs 60 people, according to La Prensa newspaper. The new production plant will create another 100 jobs. The cement producer currently operates a grinding plant at Barranquilla in Colombia.

Peru: The Supreme Court has upheld a fine of nearly US$2m by the National Institute for the Defense of Free Competition and the Protection of Intellectual Property (INDECOPI) on UNACEM. The penalty was levied due to UNACEM and its distribution network refusing to allow retailers to sell cement made by its competitor, according to the Gestión newspaper. INDECOPI said that in 2014 UNACEM and its collaborators refused to allow retailers to stock its Sol brand of cement if they were selling the rival Quisqueya brand produced by Mexico’s Cemex.

Japan: Sumitomo Osaka Cement has commissioned a new 6000t silo at its Shimizu termimal in Shizuoka. Following the upgrade, the unit now has three silos. The new silo will be used to support infrastructure projects, including expansions to the Shinkansen high-speed railway network.

US: Dragon Products’ Thomaston cement plant in Maine restarted production in early May 2019. A fire damaged the unit in late March 2019, according to the Penobscot Bay Pilot. Plant employees and contractors spent six weeks repairing and replacing building structures, conduit and wires, motors, gearboxes, bearings, material transport equipment and other equipment.

US: The Portland Cement Association (PCA) and other trade associations from the concrete and steel sector have urged that Larry Kudlow, the director of the National Economic Council, review the use of government funds on projects that use wood as a building material. The American Concrete Pumping Association, American Institute of Steel Construction, American Iron and Steel Institute, California Construction and Industrial Materials Association, Concrete Reinforcing Steel Institute, National Concrete Masonry Association, National Ready Mixed Concrete Association, Oregon Concrete & Aggregate Producers Association, Steel Framing Industry Association, Steel Manufacturers Association and the PCA expressed disappointment that the Department of Agriculture had awarded over US$8.9m for 29 projects designed to expand markets for wood products, particularly mass timber, for building construction.

The industry associations acknowledged the increase in cross laminated timber (CLT) projects in the US but they said they were concerned about the use of CLT on a large scale. They said that the grants unfairly promoted one building material at the expense of another.

Algeria: LafargeHolcim Algeria’s Oggaz cement plant has been awarded ISO 14001:2015 certification for environmental management, according to the El Watan newspaper. The plant has a total cement production capcaity of 3.8Mt/yr, comprising 3.2Mt/yr of gray cement and 0.6Mt/yr of white cement. The unit also has a waste treatment facility.

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

France: Bertrand Collomb, the former president of Lafarge, has died at the age of 76 years. He was the chief executive officer (CEO) of the building materials company from 1989 to 2003 and was later its president until 2007.

Collomb joined Lafarge in 1975 after various roles in government. He became the CEO of its North American subsidiary in 1985 before leading the company as a whole. Notable achievements during his tenure included the acquisition of the UK’s Redland and Blue Circle. Lafarge also set up a Chinese joint-venture in 1994 before many of its Western competitors.
