Reducing climate impact
As well as looking at our operations centrally, we’re also challenging individual sites to find ways to reduce their climate impact. This was formalized in 2014 when we introduced a climate efficiency Key Performance Indicator (KPI) for our factories producing packaging material and openings. Since then, a number of factories around the world have been implementing new initiatives to help them meet the KPI, including:
- At Rubiera in Italy, “free cooling” – where low external air temperatures are used to chill water which can then be used in industrial processes or air conditioning – has helped reduce cooling energy consumption by 15%.
- Denton in the US has reduced electricity costs for its compressor by 40% by detecting and repairing air leakages.
- Limburg in Germany has reduced energy consumption by 500,000kWh per year by switching to LED lights in some of its buildings.
- At Izmir in Turkey, redesigning production air flows and implementing a demand control system for ventilation has reduced energy consumption by 900,000kWh per year, while switching to LED lamps in its production hall, utilities and warehouse has saved an additional 200,000kWh.
- Our Gornji Milanovac factory has redesigned its cooling system so that it now responds automatically to variations in production levels and external conditions, reducing energy consumption by 400,000kWh per year.
- At Jurong, Singapore, chiller operation is now linked directly with production demand, and the temperature of the water adjusted automatically in response to the temperature outside. The factory has also been able to increase the temperature of the water used for cooling and ventilation, further reducing the need for the chillers. Total energy consumption has fallen by 2,200,000kWh per year.
