Sri Lanka: W Christopher Fernando has been appointed as an executive director to the board of Tokyo Cement Company (Lanka) with effect from 30 October 2014.

Fernando was appointed as Group General Manager of the company in 1991. He is also a director of Fuji Cement Company (Lanka), Tokyo Super Cement Company (Lanka), Tokyo Cement Colombo Terminal, Tokyo Cement Power (Lanka) and Tokyo Eastern Cement Company. He holds degrees in economics, is a Fellow Member of the Institute of Chartered Management Accountants (FCMA), Fellow Member of the Institute of Chartered Accountants (FCA) and an attorney-at-law.

Lafarge's third quarter financial results have coincided with the alarming news that terrorists attacked one of its cement plants in Nigeria. Thankfully nobody was hurt at the Ashaka plant. The suspected Boko Haram insurgents reportedly came looking for French nationals but the plant had been mostly evacuated following an earlier more violent incident at a nearby town. Instead they stole explosives and trucks and fled.

The resonance here with Lafarge's global financial situation is that rebel action elsewhere in the world was noted as having an adverse effect on the cement producer's coffers for the third quarter of 2013. In Iraq cement volumes have reportedly fallen by 15% in the year-to-date and almost halved in the third quarter, hit by an inability to transport cement across the country since June 2014, when Islamic State fighters captured parts of northern Iraq.

Looking at the nine months so far in 2014, Lafarge's sales have fallen by varying amounts with the exception of one territory: Middle East and Africa. Here, bucking the trend, sales rose by 3% to Euro2.8bn. The area had been the group's single largest sales region so far in 2014. Of course countries such as a South Africa are much more stable, but most other countries in the territory have had recent terrorism campaigns where a European-backed cement plant might present itself as a target.

This is not good news for a corporate balance sheet relying on these same countries to keep the profits up. However, as Lafarge states in its outlook, 'emerging markets continue to be the main driver of demand and Lafarge will benefit from its well-balanced geographic spread of high quality assets.' Spreading its bets geographically should pay off.

Also in its outlook, Lafarge announced that it intends to pause its stand-alone divestments pending completion of the planned merger with Holcim. The move suggests that the company is prioritising the impending merger over debt reduction. With Lafarge's and Holcim's recent formal notification to the European Commission of their proposed merger to obtain regulatory approval, the last of its necessary notifications worldwide, the merger is getting closer. So far, the original expectation of closure in the first half of 2015 does not look unreasonable.

When former British prime minister Harold Macmillian was asked what causes governments trouble, his apocryphal reply was, "Events, dear boy, events." The same applies to building materials producers. There may be more 'events' before the merger completes.

Nigeria: Lafarge Africa has notified the Nigerian Stock Exchange of the appointment of Adepeju Adebajo and Anders Kristiansson to the board of Lafarge Africa. Both staff members were formally appointed on 27 October 2014.

Adebajo is currently the MD of WAPCO operations. Prior to this, she served as the Chief Executive Officer and Managing Director at Mouka Limited. She was already the CEO of UTC Nigeria Plc, where she successfully turned the business around.

She previously headed strategic planning, brand management and product development at the United Bank for Africa and has had management consulting experience at Boston Consulting Group in the UK and financial analysis experience at Citibank in the UK.

Peju holds a Bachelor of Engineering (Chemical Engineering) from the Imperial College of Science & Technology, London; a Master of Engineering (Chemical Engineering) from the University of London; and a Master of Business Administration, Harvard University, Boston.

Anders Kristiansson is a Swedish citizen who started his career with Procter & Gamble (P&G) in Scandinavia and thereafter worked for P&G in South Africa. He has been a Global Divisional Controller for Eaton Automotive working in Europe and North America, whereafter he returned to Africa to oversee Celtel's finance departments across its African operations as Director of Financial Operations.

He moved to Nigeria in 2008 as Group CFO for PZ Cussons Nigeria, managing Finance and IT for PZ's five Nigerian companies. Prior to joining Lafarge, he was the CFO for NBC/Coca-Cola HBC's operations in Nigeria.

He holds a Master of Science Degree in Business Administration and Economics from the Gothenburg University, Sweden.

Germany: Hendrik Rahms will be supporting Loesche ThermoProzess GmbH (LTP) in technical sales and in the product development of thermal applications. After working as a process engineer and project manager for several years at Brinkmann Industrielle Feuerungs-Systeme GmbH, Rahms is very familiar with the products of burner and process technology as well as the customer requirements in the industry.

The 'revelation' this week that South Korean cement producers have been paid US$127m to use/dispose of Japanese coal that is thought to be radioactive certainly sounds scary. If it is true that cement made with contaminated coal has led to the construction of radioactive buildings and roads, this may have prised open a 'can of worms' for coal producers, exporters and cement players alike. According to local media, four South Korean firms - Ssangyong Cement, Tongyang Cement, Lafarge Halla Cement and Hanil Cement - received the money to use the coal between March 2011, when the Fukashima nuclear power plant started to leak radiation, until 2013. A total of 3.7Mt of cement is 'under suspicion.'

Caesium-137 is formed by fission reactions that start with uranium-235 in nuclear reactors. The Fukushima reactor that started leaking in 2011 used this type of fuel. Once it leaked, caesium-137 was deposited into the sea and onto the land, presumably also making its way into nearby coal deposits.

As it is a metal with a melting point of just 28.5°C and a boiling point of 671°C, the caesium-137 would vaporise if it were to enter a cement production line operating at 1450°C as a metal. However, caesium will not enter the cement-making process as a metal due to its rapid and explosive reaction with water. An interesting slow-motion of this reaction can be seen here.

Instead, caesium will enter the cement-making process either as its oxide or a simple salt (e.g.: caesium chloride) in the coal. The salt will be ionized in the heat of the flame, sending caesium ions into the kiln and thus direct contact with the clinker as it is being formed. Here it will become part of the matrix of the clinker and hence the final cement product. All the time the caesium-137 is radioactive.

And it stays radioactive once it is in the finished product, for example in a building or road surface. Its half-life, the time that it takes for half of the caesium-137 to decay to meta-stable barium-137 (emitting radiation as it decays), is unfortunately very well matched to the life-span of concrete buildings at 30.7 years. This means that after about 100 years of building life the building would still be around 10% as radioactive as it was when it was built.

This would certainly be a problem if the coal was highly contaminated. However, a few questions come to mind. Firstly, if the coal contains 20-73 becquerels per kilogramme (Bq/kg) of caesium-137, as has been claimed by Lee In-young, an opposition spokesman for the New Politics Alliance for Democracy party and member of the National Assembly's Environment Labour Committee, why is this a problem when the Japanese legal limit for eating caesium-137 in contaminated vegetables is all the way up at 500Bq/kg? When the most dangerous mechanisms of caesium-137 poisoning relate to accumulation in soft tissue, how can driving along a caesium-137-containing highway constitute a health risk?

Also, the coal may well start the cement making process with 25-73Bq/kg of caesium-137 but the clinker will have a lower level. This is because for every 1t of clinker the plant will typically consume just 100-200kg of coal. The caseium-137 and hence the radiation will therefore be spread out over a larger mass. A level of 50Bq/kg in the coal would translate to a clinker level of 5-10Bq/kg. This is around 100 times lower than the Japanese vegetable limit. After this, the clinker is extended with additives to make cement. This is then added to aggregates and / or sand when concrete or mortars are made, further diluting the caesium-137, perhaps to as low as 1-5Bq/kg. It is arguable that South Korea has received a higher caesium-137 dose from Japan via air and sea than via coal imports.

In light of all this, it appears that those calling for investigations on scientific grounds, like Lee, may be misguided. However, there may be political gain. The histories of Japan and South Korea are long, violent and distrustful. Indeed, according to a BBC World Service poll conducted earlier in 2014, South Korea and China jointly have the most negative perceptions of Japan of all world nations. In this environment stories about radioactive coal become much easier to believe in.

In reality the Japanese vegetable limit is well above the likely levels that might be found in any cement products resulting from the use of this coal. It is consistent with EU limits set more than 20 years earlier (600Bq/kg). A search on the US Environmental Protection Agency's website fails to bring up any formal limit. Instead it states that everyone is exposed to caesium-137 from atmospheric fallout to a low level and that the most dangerous cases are where waste metal processors unwittingly come across sources.

So on the surface then, the South Korean reaction seems like a storm in a teacup. One question remains though. If the caesium-137 levels in the coal are so much lower than the Japanese vegetable limit, why are Korean firms being paid to take it out of Japan?

South Africa: On 23 October 2014 PPC confirmed the resignation of Richard Tomes, joint managing director of PPC's South African business and one of the business's key sales and marketing personnel.

The resignation of Tomes comes a month after Ketso Gordhan resigned as CEO and the company's board subsequently plunged into a tussle with group shareholders seeking a new board. PPC said that Tomes, who joined the firm in 1998 and who shared the job as head of domestic operations with Johann Claassen, had resigned effective Thursday to 'pursue other opportunities.'

With his departure, Claassen will lead PPC's South African cement business, while Pepe Meijer remains managing director of PPC's international business. While PPC has lost an experienced managing director in Tomes, it sought to assure investors that its South African business remained under strong leadership: "Johan is a professional engineer who joined PPC in 1989 and has served as executive of cement operations and of lime," said PPC. "He has also held various other senior and general management roles across the cement and lime divisions."

It won't surprise anyone to know that cement sales have fallen in the west African countries that are suffering from the on-going Ebola outbreak. However the scale may yet be instructive for this and other crises that may affect the cement industry in the future. The local data that follows mostly comes from a report by the World Bank published in early October 2014 looking at short and medium term economic impacts, as well as Global Cement research conducted towards the Global Cement Directory 2015.

All three of the principal countries involved – Liberia, Sierra Leone and Guinea – have low gross domestic products (GDP). They do not have cement kilns but they do have grinding plants and cement import infrastructure run by both local and international firms. They also lack readily accessible limestone deposits. In the short term (in 2014) a health crisis is expected to hit manufacturing through transportation and market disruptions stemming from both direct health implications and behavioural responses.

Liberia's cement sales fell by 60% in the third quarter of 2014, a drop the World Bank attributed to causes other than the rainy season. Quarterly cement sales more than tripled in 2013 from around 10,000t to over 25,000t marking the commissioning of a new mill at the Liberia Cement Corporation (HeidelbergCement) grinding plant. Dangote also has an import terminal in the country and is building its own grinding plant. The drop in cement sales since June 2014 has nearly undone all this production growth.

Neighbouring Sierra Leone has seen a steady fall in weekly cement sales since June 2014. Similar to Liberia, it has a HeidelbergCement-run grinding plant with Dangote planning expansion soon. Guinea, which had about a sixth of the notified cases of Ebola in mid-October 2014, has seen its cement imports fall by 50% in the year so far compared to 2013.

Before readers become too depressed though, it should be considered that Nigeria has been declared Ebola free by the World Health Organisation after six weeks with no new cases. It may have been relatively expensive to contain Ebola through public health measures but the alternatives for the regional economies could have been worse. More cases are expected to arrive in Nigeria but the country has shown that Ebola can be stopped.

Immediate cement operators threatened by the epidemic include HeidelbergCement with its five grinding plants in west Africa. How an uncontrolled or high case Ebola epidemic affects Dangote's expansion plans in its 'backyard' will also be hard to predict. West Africa is the obvious place for the Nigerian cement giant to build itself up before it tackles other markets in sub-Saharan Africa that have stronger competition like South Africa's PPC. Take this market stability away and Dangote faces a direct economic threat to its growth beyond the humanitarian horror of the epidemic. What also has implications for the cement industry in Senegal, the second biggest cement producer in the region, where there are two integrated plants.

The World Bank report concludes that Liberia, Sierra Leone and Guinea could lose US$129m in GDP in a low case scenario or up to US$815m in a high case scenario. To give this some context, Sierra Leone's GDP was US$2.7bn in 2013. In a high case situation it could lose US$439m or an amount equivalent to 16% of its GDP in 2013. If and when the fight against Ebola turns, this still leaves a severe economic recession for the survivors in what is already one of the poorest countries in Africa. Cement, one of the indicators of a country's economic and industrial development, is intricately bound up in this.

India: UltraTech Cement has appointed Atul Daga as Chief Financial Officer of the company in place of KC Birla with effect from 1 December 2014. The decision was made at a board of directors meeting on 18 October 2014. The term of appointment of the managing director OP Puranmalka was extended for a period of one year until 31 March 2016.

Spain: Lafarge has appointed Maruxa Suarez as director of its Spanish plant in Villaluenga de la Sagra, Toledo. Suarez, who was previously a production director at the plant, will replace Mariano Garcia Hoyos. Suarez started working for Lafarge in 2004 at the environment unit of the company in Madrid. He later joined the management team as process engineer and production director.

Spain: Matteo Rozzanigo has been appointed as CEO of FYM, Italcementi's Spanish subsidiary. He is tasked with positioning the company in a cement market that is expected to stabilise and recover slowly after a prolonged crisis period. Rozzanigo replaces Mario Domenico Bracci, who held the post for the past three years and will now assume responsibilities for Ciments Maroc.

Rozzanigo holds an Industrial Engineering degree from the Polytechnic University of Milan, Italy and has been with Italcementi for 11 years. In the past five years, he was employed as Italcementi's director for the Near East, effectively managing the operations in Kuwait and Saudi Arabia.
