Abstract
The present invention relates to a method for the stereospecific chemical recycling of a mixture of polymers based on polylactic acid PLA, in order to reform the monomer thereof or one of the derivatives thereof. The latter may enter the traditional lactate market or once again serve as a raw material for synthesizing PLA.
