Computational modelling has helped Cyprus-based Vassiliko Cement Works to reduce NOx emissions in the calciner while increasing the use of alternative fuels, supporting the company’s drive to produce cement in a sustainable way. By V Savva and S Petrou, Vassiliko Cement, Cyprus, and MP Akritopoulos and T Abbas, Cinar, UK.

Vassiliko Cement Works was founded in 1963 in Cyprus and after its merger with Cyprus Cement Co in 2008, became one of the largest heavy industries in the country. The cement producer also serves international customers supported by its facilities at Vassiliko port. In addition to importing raw materials via the port, Vassiliko manages four quarries for the extraction of raw materials used exclusively for cement production at its integrated works. At various points in its life, the plant has been upgraded from 0.15Mta to 2Mta, including a major upgrade in 2011. This upgrade led to several significant efficiency improvements, lowering both greenhouse gas (GHG) emissions and production costs.
