Advanced technologies for treating materials and parts in contact with food in treatment and packaging systems to improve their cleanability and eliminate the release of potentially harmful elements into food. To do so, two technological directions are being investigated:

1. The applicability of nickel-free steels, developing pickling and/or passivation treatments.
2. The deposition processes of surface layers to make the surface of the components of treatment and packaging plants easier to clean. This would reduce the number of cleaning cycles required or, alternatively, the time and/or consumption of water (approximately 30%).

The objective is to obtain optimized processes scaled up to the pre-industrial phase while solving the problems related to the coating of large surfaces and the possible application and restoration of layers in the field. For both technological lines, a qualification level compatible with the issuing of certifications for food uses is to be achieved.
