The Pirelli CCM process for producing compounds uses a 100% computer-controlled pneumatic distribution system to transport the ingredients from their storage silos to the twin-screw extruders that operate continuously.

This production technology was designed by Pirelli to manage the complexity of the process deriving from the large number of ingredients required to produce the compound, while simultaneously improving its quality, and thus that of the finished product.

By means of a specially designed capture and recycling system for solid materials, CCM technology has reduced dust levels in production areas to extremely low levels.

Compared with a traditional process, the CCM process also saves energy, enabling a reduction of approximately 20% in energy consumption per unit of product.
