RONCADIN HAS INVESTED IN NEW TECHNOLOGIES THAT INCREASE THE ENERGY EFFICIENCY OF THE DEEP-FREEZING TUNNEL, SAVING APPROXIMATELY 1.7 MILLION KWH PER YEAR. RONCADIN HAS THUS OBTAINED THE WHITE CERTIFICATES, THE ENERGY EFFICIENCY CERTIFICATES OF ENEL X, A PARTNER OF THE PROJECT
Roncadin has obtained the White Certificates of Enel X for an energy efficiency intervention on the plant's freezing tunnel, which will lead to a saving of approximately 1.7 million kWh per year, equal to 600 tonnes of CO2 less emitted into the atmosphere (savings calculated on ISPRA [Italian National Institute for Environmental Protection and Research] conversion values - Report 257/2017). This investment is just the last step in a process that incorporates technological innovations that can help reduce consumption and increase sustainability.
Deep-freezing and cold chain maintenance systems are a sensitive area, which alone requires approximately 32% of the energy needed for production. The deep-freezing tunnel is a system that allows the temperature of products to be lowered from room temperature, to -25°C in approximately 30 minutes.
For years, Roncadin has been studying, along with its suppliers, methods for optimising performance, through constant monitoring that enables the predictive maintenance and precise control of consumption. Based on the surveys carried out, Roncadin has opted for a new, much more efficient deep-freezing system for production lines numbers 5 and 6, inaugurated in 2016 and 2017, respectively: specifically, together with Enel X, it designed the installation of an additional two-stage compression refrigeration unit.
Subsequent analyses have certified savings exceeding 40%, a result thanks to which Roncadin has been defined as the "best case in the industrial freezing sector" by Enel X and has obtained the White Certificates, i.e. the negotiable Energy Efficiency Certificates, which are a major incentive for interventions aimed at improving eco-sustainability.
