Thermal energy

In 2008 our largest source of thermal energy (98.9% calorific basis) was conventional: coal, pet coke, fuel oil and natural gas. Alternative fuels made up the remainder. The percentage contribution of alternative fuels (thermal basis) was reduced from 1.37% in 2007 to 1.07% in 2008 mainly due to:

  • Limited availability of alternative fuels in Greece. 
  • Increase of production volume in countries with limited opportunities to replace traditional fuels with alternatives (Egypt, Turkey).

In line with the Group policy of continuous improvement, our efforts have been strengthened to raise awareness among stakeholders at the local level and a new target has been adopted for 2015 so as to increase substitution of conventional fuels up to 4% (calorific basis) at Group level by 2015.

Electrical energy

In 2008 the total electrical energy consumption of our cement plants was 1,655GWh (5,958TJ). As in the case of thermal energy consumption, the observed increase of almost 10% compared to 2007 was the result of the increase in the volume of our production due to Group growth through new partnerships and equity changes. However, average specific consumption was 115kWh/ton cement, -a decrease of 1.5% compared to the previous year.
