La trigenerazione integrata all’industria beverage – English Subtitles
The Refresco group, to which the Spumador company belongs and which has 5 facilities in Italy produces over 1 billion bottles of mineral water and drinks. Production takes place throughout the country in 5 facilities 4 in northern Italy and one in central Italy. The facility we are in now is that of Cadorago one of the group’s biggest which produces 500 million bottles with over 450 diversified products. In 2011, our group decided to invest in a cogeneration plant for the production of 3000 Kwatt of electricity. Total production is around 50% of that consumed daily by our group as a whole. In the Cadorago facility, we consume about 30 million Kwatt/year and produce about 500 million bottles. We therefore decided to build a plant for the production of 20 million Kwatt/year, with a 3,000 Kwatt/h trigeneration plant. The trigeneration plant produces 3,000 Kwatt of electricity. We also recycle the steam and hot water, which we use for the absorbers and to produce cold water. All these processes are linked within the facility; with the electricity we produce bottles – heat the plastic blow the bottles use the compressors – and the steam is used to dissolve the sugar and pasteurize our drinks. As regards the cold on the other hand this cools the second section of the heat exchangers we have in the pasteurizer and also the bottles. All this has made possible 70% energy recycling. This energy is completely produced by us and enables us to cut costs considerably; and this is a good thing because Italian energy costs continue to rise. This type of plant very definitely has benefits and good returns in the short term with regard to the investment-return ratio. Besides being careful to produce at low costs and with an eye on energy saving Spumador also pays great attention to the environment. In fact, this plant has generated white certificates which are documents certifying that a certain reduction in energy consumption has been attained and that CO2 emissions into the atmosphere have been cut. This plant has generated 2,700 t less CO2 emissions into the atmosphere. Thanks to the excellent results achieved as regards the economic and environment parts the company has decided to invest in another cogeneration plant for the facility we have in Sulmona, in central Italy and which is being extended. This new plant will be designed to produce 2,000 Kwatt/h; it too will be a trigeneration plant and therefore able to produce steam and cold water for the production of drinks and mineral water.
