Alternative opportunities

05 February 2014, Published under Cement News

Doubling of capacity at the Jebel Ali Sewage Treatment plant in Dubai, UAE, offers domestic cement producers the potential to use excess sludge from the process as an alternative fuel source. The move would not only allow the cement industry to scale down reliance on traditional fuels and,  therefore, reduce GHG emissions but also tackle the problem of how to safely dispose of sewage sludge in an eco-friendly manner.

Alternative fuel characteristics

20 January 2014, Published under Cement News

Most microscopic analysis is based on classic studies carried out when single natural (traditional) fuels were the norm. How has the use of alternative fuels affected the microstructures observed? These observations start with a view on what differences new fuels can bring to the clinker. Figure 1: a belite cluster (150µm across) after the presence of coarse fly ash in the kiln feed Reducing conditions occur where there is an absence of oxygen such as at the bottom of an ocean o...

US energy efficiency update

09 January 2014, Published under Cement News

US cement industry energy consumption in 2012 decreased by 2.1 per cent against 2011 levels, the recently released annual Labor-Energy Input Survey by the PCA indicates. This energy decrease occurred despite the third consecutive year of increases in average clinker capacity utilisation rates, the PCA highlights. The use of coal and petcoke, the primary fuels for cement production, declined from 70  to 63 per cent. Natural gas’ contribution to the fuel mix surged from around four per cent i...

MSW co-processing in China

24 October 2013, Published under Cement News

As large volumes of common waste increasingly present a problem, China’s search for effective ways of disposing of this waste is on. With new landfill options facing opposition and causing controversy, the co-processing of municipal solid wastes (MSW) is becoming an increasingly-attractive option. Following examples in other countries, China is now actively seeking to increase its MSW usage in cement kilns, with producers such as Huaxin Wuxue and Sinoma’s Liyang having taken up the challenge...
