One of the ideas aired by several speakers at last week's 6th Brazilian Cement Congress was that using cement as a construction material is inherently a sustainable option.
The reasons for this included the durability of cement's construction products and the role cement plays in improving the living standards of a country. For example, under the onslaught of extreme weather like hurricanes, concrete structures are more likely to remain standing. Or, for a country like Brazil with sections of society living in long-term 'temporary' buildings in its favelas or shanty towns, providing affordable cement to help the country build better housing for its inhabitants is the only sustainable future that could be considered.
Perhaps in line with this concept of cement-as-sustainable-construction-material we see Semen Indonesia this week announcing expansion plans in three countries in South and Southeast Asia.
In West Sumatra a Semen Indonesia subsidiary has started building a 3Mt/yr cement plant in Padang. Then in Bangladesh Semen Indonesia revealed its intention to buy a 1Mt/yr plant. Finally, the state-owned Indonesian cement producer said that its Semen Gresik subsidiary was planning to build a new cement plant in Central Java at Rembang in June 2014. From previous press releases we can see that both new plants are FLSmidth builds. Both orders were announced in early 2014. Each has a capacity of 8000t/day.
The plans to expand outside of Indonesia echo reports that Semen Indonesia was set to buy a minority share in a Myanmar cement producer. Although the producer was unnamed as of early May 2014, Semen Indonesia CEO Dwi Soetjipto valued the stake at US$30m and the producer's production capacity at 1.5Mt/yr in comments to the Jakarta Globe.
Altogether the two new plants in Indonesia will place Semen Indonesia's total cement production capacity at 40Mt/yr by 2017 according to company figures. This would be enough to place the company within the top 20 of the world's largest cement producers by production capacity following the research from Global Cement's 'Top 75 global cement companies'.
In a nice coincidence, the company with a production capacity of 40Mt/yr on that list was Eurocement. Last week the Russian cement producer announced that it had signed contracts worth Euro387m with Chinese companies - including Sinoma, CNB, Sinomach and CAMC Engineering Co - to add 17Mt/yr cement production capacity across six plants in Russia. Another six or seven more construction agreements for cement plants are also expected to be signed in the coming months.
Certainly for the countries Semen Indonesia is focusing on – Indonesia, Bangladesh and Myanmar, with low gross domestic product per capita – providing the raw material for stronger and more durable buildings covers some of the sustainability bases. Yet if all these new plants only use fossil fuels and are subject to few environmental restrictions then that undermines some of this. However, whether all this expansion is sustainable or not, the cement industry never remains stationary.
