Energy

Specific Energy ConsumptionPirelli monitors and reports its own energy consumption by using two principal indicators:

  • absolute consumption, measured in TJ, which includes the total consumption of electric energy, natural gas, and petroleum derivatives (fuel oil, gasoline, diesel, and LPG);
  • specific consumption, measured in GJ per tonne of finished product, which indicates the energy used to produce a tonne of finished product. The specific consumption is the index used to measure process quality, regardless of annual production volumes.

The Pirelli Industrial Plan has set a target to reduce its specific consumption of energy by 15% from its 2009 level by 2015. In 2011, the energy efficiency improvement plan continued to be implemented at all Group plants. Initiated several years ago, it is characterised by measures aimed at:

  • improving energy management systems, by exactly measuring consumption and focusing daily on technical indicators;
  • improving the quality of energy transformation by streamlining resource and plant use;
  • improving the efficiency of distribution plants;
  • improving the efficiency of production plants;
  • recovering energy for other uses;
  • applying targeted maintenance plans in order to reduce energy-waste.

The following tables and graphics illustrate the trends of absolute and specific consumption by the Group during the three-year period 2009 – 2011.

The downward trend in specific consumption as measured by the targets set for 2015 appears to be firmly underway, and at December 31, 2011 shows a performance of over -2% compared with 2010 and about -8% compared with 2009. In 2011 efficiency measures made it possible to save over 310 TJ. The previous year they generated savings of about 770 TJ.

This excellent result has been achieved in spite of the negative impact stemming from growing focus on the production of higher energy content products, i.e. Premium products, local contingencies having nothing to do with planned efficiency measures, and the growing impact of the steel cord business on Group consumption indices. All these variables have rendered the efficiency plan more dynamic and continuously up to date. The following graphics illustrate the different energy sources used by Pirelli in 2011 and, in particular, the proportion of renewable energy against all electric power purchased.
