• Reduce the volumes of dust emissions;
  • Get below the norms stipulated by the new Ukrainian legislation and meet more strict EU standards.


Mykolaiv Cement Plant was built in 1950 and acquired by Lafarge in 1999. Most of the plant's wet line equipment has been operational for over 60 years.

At the end of 2010, Lafarge Ukraine started the implementation of a new environmental project: the reconstruction of the electrostatic precipitators (ESPs) of 4 rotary kilns, from September 2010 until March 2011, with a staggered scheduling according to the Kiln Winter Stoppages.

The scope of the project was similar for all kiln ESPs: Keeping the Housing and Support Structure, exchanging internals filters and Electrical components required to achieve the dust emission performance figures:


  • Discharge electrodes including Rapping system;
  • Collecting Electrodes including Rapping system;
  • Gas Distribution Inlet;
  • Transformer and Rectifier Set;
  • Monitoring and Control System.


The improvement became obvious right after the implementation of the project. While the Ukrainian law sets the emission limit at 800mg/m³ for Kilns without alternative fuels, the dust emissions went down by more than 60%. In the normal operating mode:


  • they are below 50 mg/m³ for the kilns fed with alternative fuels;
  • they reach 150 mg/m³ for a kiln in which no alternative fuels are burned.

People concerned

  • Local companies ELEX and Rensy;
  • Lafarge Ukraine teams in Mykolaiv.
