Energy management for pet recycling systems

A system for recycling plastic, comprising:

• a plurality of energy consumers,
• at least one intelligent energy management unit in communication with the energy consumers and in communication with one of a central control unit for the energy consumers of the system, a plurality of decentralized control units of the energy consumers of the system, and a combination thereof, and being configured to
• detect the energy consumption of each individual energy consumer of the plastics recycling system,
• detect the operating state of the plastics recycling system,
• identify the energy consumers required for the operating state,
• use a hierarchy of the energy consumers depending on one of their energy consumption, their operating mode, the operating state of the plastics recycling system, and any combination thereof, and
• the required energy consumers are supplied with energy by taking into account the hierarchy, wherein a maximum peak power which the energy management unit can make available to the entirety of the required energy consumers is smaller than a sum of the rated peak powers of the individual required energy consumers.
