With a large oil and fleet demand for manufacturing bulk GGBS (cement) at their plant in Kilkenny, O’Brien Cement management is concerned about promoting a sustainable energy practice while meeting its daily business objectives. However, after successfully installing their new burner and optimizing their manufacturing process the benefits and cost savings were clear.
The 3 Counties Energy Agency (3cea), through the Sustainable Energy Authority of Ireland’s Better Energy Communities programme, is helping by administering state-wide funding for energy efficiency and renewable energy projects.

- Thanks to the heating and process design upgrade completed through the BEC 2016 programme, O’Brien Cement has saved money and reduced their carbon footprint.
- The raw material treatment process has been redesigned. Previously a three stage raw material treatment process, the redesign has converted this to a single stage process, lowering energy demand as the process has decreased energy losses.
- O’Brien Cement has been upgraded to a high efficiency, 4 MW burner with future capacity. This device guarantees a more efficient fuel consumption when generating the required heating load for their cement process.
