Okwangoku ezona zixhobo zidumileyo zinokonakalaI-PLAkunye ne-PBAT, zombini zinokonakala ngokupheleleyo.
Iiplastiki ezinokonakalabhekisa kwiklasi yeeplastiki ezineemveliso ezinokuthi zihlangabezane neemfuno zokusetyenziswa ngokwemigaqo yokusebenza, zihlala zingatshintshi ngexesha lokugcinwa, kwaye zinokutshatyalaliswa kwizinto ezingenabungozi zokusingqongileyo phantsi kweemeko zendalo zendalo emva kokusetyenziswa.Ke ngoko, ikwabizwa ngokuba yiplastiki eyonakaliswa kokusingqongileyo.
Kukho iindidi ngeendidi ezintsha zeeplastiki: iiplastiki ezifotayoiiplastiki ezinokubola,ukukhanya/i-oxidation/iplastiki ezonakaliswa ngokupheleleyo ngokwebhayoloji, iiplastiki ezingonakaliswa ngekharbon diokside esekwe kwi-biodegradable, kunye ne-thermoplastic starch resin esonakalayo.
Ukuthotywa kwepolymer kubhekiselele kwinkqubo yokwaphula i-polymerized macromolecular chain ngenxa yeekhemikhali kunye nezinto ezibonakalayo.Inkqubo yokuthotywa kwe-macromolecular chain breakage yeepolymers ezivezwe kwioksijini, amanzi, imitha, iikhemikhali, ungcoliseko, amandla omatshini, izinambuzane kunye nezinye izilwanyana kunye ne-microorganisms kubizwa ngokuba kukuthotywa kokusingqongileyo.
Ukuthotywa kunciphisa ubunzima bemolekyuli yepolymer, kwaye iipropathi ezibonakalayo zepolymer material ziyancipha de i-polymer material iphulukane nokusebenza kwayo.Le nto ikwabizwa ngokuba kukuthotywa kokuguga kwezinto zepolymer.
Ukuthotywa kokuguga kweepolymers kuhambelana ngqo nokuzinza kweepolymers.Ukuthotywa kokuguga kweepolymers kunciphisa ubomi benkonzo yeeplastiki.Ngenxa yesi sizathu, ukususela ekufikeni kweeplastiki, izazinzulu ziye zazinikela kuphando lokuchasa ukuguga kwezinto ezinjalo, oko kukuthi, ukuzinzisa, ukwenzela ukuvelisa izinto ezizinzileyo zepolymer, kunye nezazinzulu ezivela kumazwe ahlukeneyo zisebenzisa. Ukuguga kokuziphatha kokuthotywa kweepholima.Ugqatso lokuphuhlisa iiplastiki ezinokonakala kokusingqongileyo.
Iinkalo zokusetyenziswa eziphambili zeeplastiki ezichithwayo zezi: ifilimu ye-mulch yezolimo, ezahlukeneyo piingxowa zokupakisha ze-lastic,izikhwama zenkunkuma, izikhwama zokuthenga kwiindawo zokuthenga kunye ne-tableware elahlayo, njl.
