Process and system for recovering polyamides and polymers from composite articles

A process for recovering at least one of a polyamide and a polymer from one or more composite materials, the process comprising:

• dissolving the at least one polyamide present in the one or more composite materials in a solvent;
• separating at least one undissolved polymer from the solution by filtration;
• evaporating part of the solvent from the solution containing the at least one polyamide;
• neutralizing separately, using an alkali, the solvent remaining with the at least one polyamide and with the separated at least one polymer;
• and
• washing, filtering and drying separately the mixtures comprising the at least one polyamide and the at least one polymer to obtain polyamide and polymer.

A system for recovering at least one polyamide from one or more composite materials, the system comprising:

• a dissolution reactor for dissolving the at least one polyamide present in the one or more composite materials in a solvent;
• a filter unit for separating at least one undissolved polymer from the solution;
• a reactor for evaporating the solvent containing the at least one polyamide;
• a polyamide neutralization reactor for neutralizing, using an alkali, the solvent remaining with the at least one polyamide;
• and
• a polyamide filter and dryer for at least one of:
• washing, filtering and drying of the mixture to obtain polyamide.
