US: The Japan Coal Energy Center (JCOAL), GreenOre Clean Tech, Columbia University and Wyoming Infrastructure Authority (WIA) have entered into a memorandum of understanding (MOU) to test carbon utilisation and recycling technology. GreenOre Clean Tech, using technology under license from Columbia University, will use testing space at the Integrated Test Center (ITC) near the Dry Fork Station coal-fired power station in Gillette, Wyoming. Calcium carbonate produced through CO₂ mineralisation could then potentially be used for aggregates, concrete production or in paper production. The test will be funded by JCOAL with additional support from project partners.

The State of Wyoming and JCOAL have been working together since 2016, when they signed an initial MOU committing to cooperation in coal research and development of technologies and coal trade. JCOAL operates under the supervision of the Ministry of Economy, Trade and Industry of Japan and is supported by more than 120 member coal-related businesses, including Kawasaki Heavy Industries, Mitsubishi Hitachi Power Systems, Nippon Steel and Toshiba. Kawasaki is scheduled to test its solid sorbent capture technology at the ITC beginning in 2021.

Canada: McInnis Cement has closed a US$380m refinancing deal. US$230m will be provided by an increase McInnis Cement’s senior loan from a syndicate of 11 Canadian and international banks and the remaining US$150m comes in the form of a loan by the Caisse de dépôt et placement du Québec (CDPQ) and Beaudier. This refinancing also makes it possible to repay a bridge loan granted by BlackRock in 2016.

The cement producer also provided details on various projects it is undertaking. Two new cement silos will be built at the company’s integrated cement plant at Port-Daniel–Gascons. Nearly 200 workers will be mobilized on the site during the peak construction period of the two silos, during the autumn of 2019.

Its Bronx Terminal in New York, US has doubled its loading capacity for customers. A second truck-loading lane is now fully operational. A new 40,000t warehouse is currently under construction at its Providence Terminal in Rhode Island, US bringing the total storage capacity to 75,000t. A new truck-loading lane will also be added and commissioned in time for the 2020 spring construction season. McInnis Cement has also confirmed the charter of the NACC New Yorker, a 24,000t self-unloading vessel, in conjunction with Nova Marina Carriers. It will join other vessels in its fleet including the NACC Quebec (14,000t), the Cielo di Gaspesie (35,000t) and the Resolute unloading barge.

US: Companies comprising the informal Port of Alaska Users Group at Anchorage have requested that the local government delay plans for a US$220m petroleum and cement import terminal. The group, that includes fuel companies, are concerned that the project will incur tariffs that could damage their businesses, according to the Alaska Journal of Commerce newspaper. Costs for the proposed marine terminal have become uncertain due to damage caused to the site by an earthquake in late 2018. The group is made up of eight companies including Alaska Basic Industries, a cement distributor.

US: Vulcan Materials has elected Michael Wilson to its board of directors. He will serve on the Audit and Safety, Health and Environmental Affairs Committees of the construction aggregates producer. Wilson is the president and chief executive officer (CEO) of Ingevity Corporation and a member of Ingevity's board of directors. Ingevity is a global supplier of specialty chemicals, carbon materials and engineered polymers. With the addition of Wilson, Vulcan's 10-member board consists of nine independent directors.

Germany/US: Germany’s Baltrader and US-based United Bulk Carriers (UBC) have launched the Cement Carrier Alliance (CCA) to cooperate the marketing of their respective fleets of pneumatic cement carriers. The aim of the deal is to offer a wider range of vessel sizes to existing and new customers while enhancing marketing to current and developing markets. The two companies operate 15 self-discharging cement carriers with a range of 3000 – 15,000DWT vessels.

Both companies will remain independent entities each operating out of their own offices while offering continuity in their customer relationships. CCA will be jointly represented by the UBC office in Philadelphia and the Baltrader office in Hamburg.

US: Lehigh Cement has received permission from the Indiana Department of Environmental Management for a US$600m upgrade to its integrated Mitchell plant. IDEM's Office of Air Quality granted a modification to the unit’s air permit in late June 2019 following a period of public comment, according to the Times-Mail newspaper. The subsidiary of Germany’s HeidelbergCement plans to increases the production capacity at the plant to 2.8Mt/yr from 0.8Mt/yr. Construction is scheduled to begin in 2020 and completion of the new plant is anticipated by the end of 2022. Once finished the upgrades will create 52 new jobs at the unit.

US: Hawaii’s Department of Transportation plans to use carbon-injected concrete for its new projects. This will include a new structure to protect a highway tunnel from rockfalls, according to Reuters. The Department of Transportation was testing CO₂-injected concrete on an access road project with CarbonCure Technologies in May 2019. The latest decision follows a resolution by state legislators that city administrators ‘consider’ using CO₂-injected concrete in city and county infrastructure where concrete is used.

In late June 2019 CarbonCure announced that its had formed a partnership with HC&D Ready Mix, a local concrete producer, to use its CO₂-injected concrete process. It is the second deal with a concrete producer in the state that CarbonCure has arranged.

US: Mississippi Lime Company has executed a definitive agreement to acquire Southern Lime, the lime business of Covia based in Calera, Alabama. No value for the transaction has been disclosed. The deal is also subject to regulatory approval.

Southern Lime supplies high-calcium quicklime and hydrated lime products to customers in the Southeastern US, and across a range of end uses and applications. The Calera operation will increase Mississippi Lime’s production facilities to nine locations, supported by a network of distribution sites throughout the country. The business will be fully integrated into existing Mississippi Lime operations.

Turkey: Turkish Cement Manufacturers’ Association (TÇMB) chairman Nihat Özdemir says that the local industry needs to focus on exports rather than for local consumption. He made the comments at a meeting between the TÇMB and the Cement Industry Employers' Association (ÇEİS) hosted by Deloitte, according to the Dünya newspaper. Exports grew by 46% year-on-year in the first half of 2019 to a value of US$444m driven by deliveries to the US, Ghana and Israel. ÇEİS chairman Suat Çalbıyık called on the Turkish State Railway company to abolish its fixed tariff for goods moved up to 150km to further support the industry.
TÇMB data shows that local consumption fell by 24% year-on-year to 5.12Mt in the first quarter of 2019 from 6.74Mt in 2018. Domestic sales fell by 34% to 3.98Mt from 5.99Mt. Exports rose by 37% to 0.94Mt from 0.68Mt. Local decline in the market has been blamed on a weak housing market and a slowdown in the Turkish economy.

Charah Solutions has been steadily building up its fly ash distribution business in recent years with an eye on the supplementary cementitious materials (SCM) market. This week it opened the third of its new series of SCM grinding plants, at Oxnard in California, US. The unit sticks out because it is focusing on grinding natural pozzolans. The plant will receive natural pozzolan by truck and rail and then use Charah’s patented grinding technology to produce pozzolan marketed under its MultiPozz brand. The previous plants in this series mentioned natural pozzolans but this is the first to promote it explicitly.

The change is potentially telling because global demand for granulated blast furnace slag (GBFS) outstrips supply. Both performance benefits and environmental regulations are pushing this. It’s a similar situation for fly ash, also driven by trends to close coal-fired power stations in some countries. As Charles Zeynel of SCM trading firm ZAG International explained in the March 2019 issue of Global Cement Magazine, “...volcanic pozzolans are a potential SCM of the future. This is gaining traction, but it’s slow progress at the moment. This will be the answer for some users in some locations.”

The problem though is that natural pozzolans are down the list of preferred SCMs for their chemical properties after silica fume, GBFS and fly ash. The first is expensive but the latter two were traditionally cheap and easy to obtain if a cement or concrete producer had access to a source or a distribution network. Natural pozzolans are very much subject to variations in availability.

It’s no surprise then that Charah is promoting natural pozzolans in a Californian plant given that state’s environmental stance. It’s unclear where Charah is sourcing their pozzolan from but they are not the only company thinking about this in the US. Sunrise Resources, for example, is working on the environmental permits for a natural pozzolan mine near Tonopah in Nevada. As it described in its company presentation, California and Nevada are the most affected states in the fly ash supply crisis because they are, “...at the end of the line when it comes to rail deliveries from power stations in central and eastern USA.” It also estimated that California used 0.9Mt of pozzolan in its cement production of which about 90% is fly ash. The state produced 9.6Mt in 2015. Other companies are also mining and distributing natural pozzolans in the US as the website for the National Pozzolan Association (NPA) lists. Although, if this line-up is comprehensive, then the field is still fairly select. Most of these companies are based in the west of the country.

One last thing to consider is that various groups are tackling a potential future lack of SCMs for the cement industry by making their own pozzolanic materials through the use of calcined clay. These groups include the Swiss-government backed LC3 project and Cementir’s Futurecem products. Using clay should bypass the supply issues with natural pozzolans but the cost of calcining it requires at the very least an investment to get started.

As concrete enthusiasts often point out, a variant of pozzolanic concrete was used by the Romans to build many of their iconic structures, some of which survive to the present day. To give the last word to the NPA, “What is old is new again: natural pozzolan is back!” If environmental trends continue and steel and coal plants continue to be shut then it might just be right.
