Abstract
The invention relates to a method of upgrading a composite material containing fibrous matter and non-fibrous plastic matter. The inventive method includes the following steps consisting in: cooling the composite material to a temperature of between −40° C. and +10° C., grinding the cooled composite material in order to disconnect the fibrous matter from the non-fibrous plastic matter; and separating the fibrous matter from the non-fibrous plastic matter.
