Next MIRS is the second generation of the Pirelli process for robotic production that has already gained fame around the world. The eco-sustainable efficiency of Next MIRS is realised in processes and products, as illustrated below.

Extrusion process

In contrast with the MIRS project, the Next MIRS process has adopted a new “cold,” i.e. low temperature extrusion system, with consequent reduction in heat use. The efficiency of extruder screws has also been improved. All of this translates into lower emissions and also improved product performance, especially in terms of maintaining the original characteristics of the compounds during use.

Vulcanization process

Pirelli has developed a new concept that will lead to a more uniform degree of vulcanization between the different parts of the tyre.

The production efficiency of the vulcanizer will increase up to 30%, resulting in a substantial reduction in environmental impact, and particularly:

  • a proportionate reduction in the number of vulcanizers and moulds, and thus a reduction in CO2 emissions during production;
  • a considerable reduction in the energy used, mainly for the energy dispersed by the vulcanizers and thermal plants serving them.


With the Next MIRS technologies, it is possible to realise semi-finished products that are more exact in terms of weight (the variability of weight is about 1/3 compared with traditional production processes).

Consequently, it is possible to reduce the weight of specific products by about -4/5% and thus, in addition to a corresponding reduction in raw materials used, realise a significant reduction in the rolling resistance base load of the product in use. This will reduce the environmental impact associated with fuel consumption, beginning with CO2 emissions.
