Process for recycling of polymers from crushed "post-consumer" materials to supply parts for motor vehicles having, after coating with paint, the following appearance requirements: - gloss under incident angle of 20° of between 65 % and 90 % reflected light, - a maximum of 4 faults of type grains, craters, or particles per m 2, of size greater than 50 μm, - resistance to external aggression defined by no peeling after adhesion test under each of the following conditions: in the initial state, after the part has been immersed in demineralised water at 40 °C for 10 days or 60 °C for 3 days, the resistance to external aggression test being carried out 1 hour after taking out and wiping the part, and after exposure at a temperature of 85 °C for 7 days, the resistance to external aggression test being carried out after cooling to room temperature, and - peeling of the paint film less than 2 cm 2 over the entire part, after the part has been given at least five X-cuts down to the substrate each inside a square of side 10 cm and has then been subjected for 30 seconds to a water jet at 85 °C at a pressure of 65 bar from a flat nozzle of a high-pressure cleaner positioned 10 cm from the part, the peeling of each cross not exceeding 1 cm 2, the parts being made of polymers, some of which are obtained from ground "post-consumer" materials, the percentage by weight of polymers obtained from ground "post-consumer" materials being greater than or equal to 30, or preferably greater than or equal to 50, or still more preferably equal to 100, process comprising a step for extracting volatile organic compounds present within the polymers, characterised in that the volatile organic compounds are extracted by contacting the ground material with a solution comprising at least a wetting agent and an agent for solubilising fatty acid esters, at a temperature between 15 °C and 5 °C below the boiling point of the solution, process in which the agent for solubilising the fatty acid esters is an acid added to the solution so that the solution pH is greater than or equal to 2 and less than or equal to 5, or preferably between 4 and 5. - gloss under incident angle of 20° of between 65 % and 90 % reflected light, - a maximum of 4 faults of type grains, craters, or particles per m 2, of size greater than 50 μm, - resistance to external aggression defined by no peeling after adhesion test under each of the following conditions: in the initial state, after the part has been immersed in demineralised water at 40 °C for 10 days or 60 °C for 3 days, the resistance to external aggression test being carried out 1 hour after taking out and wiping the part, and after exposure at a temperature of 85 °C for 7 days, the resistance to external aggression test being carried out after cooling to room temperature, and in the initial state, after the part has been immersed in demineralised water at 40 °C for 10 days or 60 °C for 3 days, the resistance to external aggression test being carried out 1 hour after taking out and wiping the part, and after exposure at a temperature of 85 °C for 7 days, the resistance to external aggression test being carried out after cooling to room temperature, and - peeling of the paint film less than 2 cm 2 over the entire part, after the part has been given at least five X-cuts down to the substrate each inside a square of side 10 cm and has then been subjected for 30 seconds to a water jet at 85 °C at a pressure of 65 bar from a flat nozzle of a high-pressure cleaner positioned 10 cm from the part, the peeling of each cross not exceeding 1 cm 2,
