Some of the Group’s Italian plants self-produce part of the energy used. In particular, three use photovoltaic electricity, with systems installed on the roofs of buildings or on the ground: Prima Eastern, which owns a plant that in 2021 produced 1,795 GJ, Prima Components Anagni, with a plant that has produced 2,491, and Prima Components Ferentino, which saw a production of 2,693 GJ. The plant of Prima Components Paliano owns a generator of electric energy of rescue, with License Agency Customs, but without meter. The Sole Oderzo plant, through cogeneration, produced in 2021 2,963 MWh of electricity, equal to 10,667 GJ, consuming for this purpose 33,352 GJ of natural gas; also the Sole Scanzorosciate plant has a cogeneration plant, which, however, is managed by an external company from which Scanzorosciate buys the electricity produced. Finally, we point out that in 2021 Prima Eastern plant sold 66 MWh of self-produced electricity (equal to 238 GJ).

In order to improve the environmental performance and reduce the energy consumption of production activities and offices, the PSC Group has launched several initiatives aimed at a constant and continuous improvement in this area. Among these it is significant to remember for 2021:

• The installation of thermostats in association with the heating system of Sole Pontedera
• The post-combustion of solvents from painting plants with an energy recovery used for air conditioning; the heating of work environments through hot water return from cogeneration systems; the progressive replacement of the old lighting systems with other LEDs; the reuse - after filtering - of the hydraulic oil of the presses in Sole Oderzo
• Maintenance of the cooling tower and replacement of a compressor with a better energy class at Sole Hörgertshausen
• The installation of lighting systems with lower consumption and photocells for the automatic switching on and off of lights in Brazilian plants
• The introduction of more energy-efficient production machines and equipment to PSMM Pernambuco
• Adoption of environmental management systems in line with ISO14001;
• The design, at Sole Oderzo, of a trigeneration plant that from 2022 will cover all the thermal and refrigeration energy needs and 25% of electricity.

The following table shows the changes in energy consumption compared to machine hours worked (GJ/h).
