Ratti is actively engaged in initiatives for reducing consumption that involve investments and the reviewing of processes and work routines. In 2019 Ratti obtained ISO 50001 energy certification. For some time the company has been using a measurement system that involves the main sources of consumption.
In order to identify how much each form of consumption contributes to its environmental impact, Ratti carried out an LCA (Life Cycle Assessment) of its organization at the Guanzate site (LCA gate to gate, reference standard ISO 14040 – 44: 2006), assigning the task of carrying it out to a external specialist company. The study was reviewed by the Bureau Veritas certification company.
The measures taken to improve energy efficiency include the installation of a system to recover heat from the fumes of the steaming department, which also involved the washing, finishing and heating plant departments, resulting in a reduction in consumption. The company also replaced the air conditioning plant of the Weaving and Printing departments, installed a lighting system with LED lights in the printing room and in the maintenance tunnels, and used high-efficiency batteries that guarantee energy savings of about 30%. Finally, the burners of the production department’s heating plant were replaced with burners fitted with inverters and an oxygen probe.
The table below shows the consumption.
A photovoltaic plant is in operation at the Company’s Guanzate plant for the production of electricity for its own use.
With respect to air conditioning and heating systems, the Guanzate site follows a specific procedure in managing air conditioning systems and atmospheric emissions that ensures compliance with the Single Environmental Authorization. Specifically, to curb polluting emissions into the atmosphere, in 2019 a burner of the central heating system of the manufacturing department was replaced with a state-of-the-art burner that emits lower amounts of nitrogen oxides. During 2019, renewable energy generation from the photovoltaic system of the Guanzate site allowed to generate 873,976 kWh of electricity, up 4.98% year-on-year, selling part of the power generated into the grid—thus preventing 314 tonnes of CO2 emissions. In addition, starting from 2020 100% of the electricity purchased for the site in Guanzate will come from renewable sources certified with a Guarantee of Origin, dramatically reducing CO2 emissions associated with the Group’s purchases of electricity.
