CHAPTER 4 | Ratti’s environmental commitment
in the electricity cabinets, control panels in the departments, principal machinery) to individual users, and data gathering was imposed on a daily basis. In this way, at the Guanzate site, Ratti ensures compliance with the applicable authorisations,
laws and regulations, and that the environmental performance of specific KPI parameters is monitored by surveillance plans that are defined and managed by the dedicated procedure “Surveillance, Monitoring and Measurement”.
With the goal of developing a consumption monitoring system that is increasingly extensive and integrated, Ratti SpA has set itself the objective over the next few years of increasingly monitoring individual users.
Action to improve energy efficiency
Among the most significant investments made since 2014 at the Guanzate plant in terms of improving consumption is the replacement of old machinery and the installation of a machine that recovers heat from vapour released by the steaming department.
This also involved the washing and finishing departments and the power plant and resulted
in a significant decrease in the consumption
of electricity and methane and making the departments increasingly efficient.
The replacement of the old washing lines and
the installation of a system recovering heat from wastewater has led to a reduction in both water and energy consumption: the energy is used to heat

Following the important interventions of the last five years, in 2018 a number of actions were taken aimed at further reducing superfluous consumption of electricity. Among these:
• The air-conditioning system in the Weaving building was replaced by an innovative system that is more energy efficient;
• A lighting system with LED lights was installed in the printing room and in the maintenance tunnels, following completion of the relamping plan implemented in recent years which involved internal and external lighting throughout the company;
• Someolder-generationbatteriesandbattery chargers, which had reached the end of their useful lives, were replaced by high-efficiency batteries, which offer recharging savings of around 30%;
• The Uninterruptible Power Supply (UPS)
group for the Centro Elaborazione Dati (CED data processing centre) was replaced by a more innovative and efficient group.
The UPS static continuity group guarantees a constant supply of electricity to electrical devices, and is needed where there is electrical equipment that can under no circumstances be without an electrical current.
During 2018 activities were also carried out aimed at certifying Ratti’s Energy Management System in accordance with the standard ISO 50001:2018. An analysis and diagnosis of energy consumption was carried out ahead of the certification programmed for 2019.
In addition to the reduction in electricity consumption, investments were made which led to a reduction in the consumption of methane and to the replacement of machinery that consumes that gas indirectly. In terms of monitoring consumption, all methane gas meters were replaced by the latest generation of systems that allow remote reading, so that consumption data can be archived and accessed more frequently.
With regard to the air-conditioning and heating systems, the Guanzate plant follows a specific procedure for managing air-conditioning systems and for managing emissions into the atmosphere, that ensures compliance with the Autorizzazione Unica Ambientale (single environmental authorisation).
In particular, 2018 saw the following initiatives:
