Abstract (en)
[origin: WO2022157222A1] A method is described for preparing PLA by oligomerization and polymerization of lactic acid consisting, at the start, completely or partly, of lactic acid originating from supports containing PLA and that have been used as supports for reels of textile yarn and/or film, this PLA being recycled in the form of lactic acid. Also described is the use of these resulting supports as a support for textile yarn and/or plastic film.
