2014 Annual Report56

Replacement of old boilers with new boilers providing higher yields (a three year plan has been developed and progress is regularly monitored); Renovation of ammonia-based cooling equipment to reduce the quantities of NH³ used and increase performance; Appraisal of existing refrigeration equipment and implemen- tation of action plans producing excellent results at numer- ous sites.

Energy distribution:

Lagging; Systematic tracking of compressed air leaks; Installation of variable speed pumps, ventilators and compressors and variable pressure settings for networks. Inspection of steam network bleeders.

Energy consumption:

Development of metering and monitoring of yields; Development of a three year plan for renovation and enhancement of cleaning-in-place equipment; Deployment of membrane-based processes in partial or full replacement of evaporators.

Renewable energies Sites equipped with wood boilers confirmed their perfor- mance in 2014.

The wood used is sourced from renewable forests managed by the Office National des Forêts and giving priority to local supply.

Protected zones A limited number of sites (5.1%) are implanted in protected zones such as natural parks, forests and Natura 2000 zones.

In order to preserve them, the action taken involves in particu- lar preserving forest areas by planting native trees and limiting discharges to the atmosphere.

POLLUTION AND WASTE MANAGEMENT

Limiting air pollution On a like-for-like basis, there was a fall of 4.1% in CO

energy consumption at production sites.

The improvement was achieved by means of best practices such as subscribing to the Objective CO

charter which produced very positive impacts on the emis- sions associated with milk collection, inter-plant transfers and finished product distribution.

These results were mainly attributable to the following actions which are renewed and improved each year:

Manufacturing process control including:

Reduction of water consumption, thus mechanically reduc- ing the volume of wastewater;

Reduction in the proportion of pollutants in water before it goes to the treatment plant thanks to the reinforcement and systematization of controls; Installation of waste water meters and turbidity meters designed to measure and monitor changes in load.

Reducing wastewater discharges and improving wastewater quality Total wastewater discharges amounted like-for-like to 12.6 million m³, down 0.7% over 2013. 98.9% of wastewater is purified before being discharged into the natural environment.
