Empa li-recycling le li-biopolymers li tobana le litšitiso.Leha ho na le boiteko ba lilemo tse ngata, sekhahla sa ho nchafatsa lipolasetiki naheng ea Amerika, mohlala, se ntse se le ka tlase ho 10%.'Me li-biopolymers - hangata lihlahisoa tsa ho belisoa - li sokola ho fihlela ts'ebetso e ts'oanang le tekanyo ea tlhahiso ea li-polymers tsa maiketsetso tseo li reretsoeng ho li nkela sebaka.
PBAT e kopanya tse ling tsa litšobotsi tse molemo tsa li-polymers tsa maiketsetso le tsa tlhaho.E tsoa ho tse tloaelehileng tsa petrochemicals-purified terephthalic acid (PTA), butanediol, le adipic acid-'me leha ho le joalo e ka senyeha.Joaloka polymer ea maiketsetso, e ka hlahisoa habonolo ka tekanyo e kholo, 'me e na le thepa ea' mele e hlokahalang ho etsa lifilimi tse feto-fetohang tse loantšanang le tse tsoang li-plastiki tse tloaelehileng.
