Supplementary cementitious materials (SCMs) are widely applied in cement and concrete products due to some immediate advantages such as: Lower production costs, improved properties, resource efficiency and lower CO2 emissions. By far the most used SCM is fly ash, a by-product from coal-fired power plants. However, due to the widespread reduction in coal usage, as seen in Europe, this source is now leaving a gap that must be filled. CemGreen has developed a patent-pending process, called CemShale, in which globally available shale is converted into a valuable SCM that can substitute fly ash one-to-one.

Lindner’s next-generation Atlas 5500 pre-shredder is fully operational at several waste processing sites across Europe. Lindner invited Global Cement Magazine to see it in operation near Klagenfurt, Austria, where we spoke to Stefan Scheiflinger-Ehrenwerth, Head of Product Management, about the Atlas range, refuse-derived fuel production and the importance of waste sorting practices for the cement industry in 2019 and beyond.

The central theme of the 2019 Cembureau Energy Market Prospects (CemProspects) conference in Kraków, Poland on 7-9 October 2019 was one of market uncertainty. Geopolitical events, trade wars, environmental legislation and indicators of a potential global recession have all contributed to a volatile situation for energy forecasters. Added to this, as environmental legislation tightens, new products have become commodities or are on the way to becoming so. Such proto-commodities include carbon credits in emission trading schemes and waste fuels such as refuse-derived fuel (RDF).

In this article, Global Cement Magazine appraises the cement situation in 10 East African nations: Burundi, Djibouti, Eritrea, Ethiopia, Kenya, Rwanda, South Sudan, Sudan, Tanzania and Uganda.
