LEDs: lots of light for little electricity
Our Italian dessert producer Rachelli is renowned beyond its country’s borders for its organic and Demeter specialities. Recently, energy-saving light-emitting diodes (LEDs) were installed at the site in Pero, Milan, reducing its CO2 emissions by nearly 70 tonnes a year.
Artificial light is integral to everyday life, and working from sunrise to sunset has long been a thing of the past. In many places, though, people still relay on outdated technologies that are far from efficient. This waste is especially problematic from an environmental perspective if the electricity is generated from fossil fuels.
Light-emitting diodes can help tangibly reduce electricity consumption as well as the associated emissions and costs. With this in mind, renovation work was recently carried out at Rachelli, one of our three Italian dessert producers, to replace around 340 lights with new, efficient LEDs. Thanks to this measure, it will be possible to lower annual electricity consumption by around 120 megawatt hours and reduce annual CO2 emissions by almost 70 tonnes. In addition, the longer service life of the LEDs means they need to be replaced far less frequently, which is of particular benefit in the production environment.
LEDs becoming the norm
In recent years we have switched to energy-saving LED lighting at a number of different sites, often as part of broader reconstruction work. Examples include the renovation of the five Gruyère cheese cellars in Moudon in 2015, as well as the use of LEDs in the car park in Suhr and in various production and storage areas in Emmen and Ostermundigen. Further major LED projects are currently in the pipeline.
When renovating the lighting in our production and logistics buildings, we are consistently opting for LED technology and achieving power savings of between 45 % and 70 % – in some cases, where feasible, in combination with motion detectors and daylight-dependent control. The longer service life of the LEDs also means that lights in areas of the production halls that are difficult to access need to be replaced far less frequently.
