Inkcazo yeeplastiki ze-biodegradable, kukukhomba kwindalo, njengomhlaba, isanti, imo engqongileyo yamanzi, indawo yamanzi, iimeko ezithile ezifana ne-composting kunye neemeko zokugaya i-anaerobic, ukuthotywa okubangelwa yintshukumo ye-microbial yobukho bendalo, kwaye ekugqibeleni. ibolile yaba yikharbon diokside (CO2) kunye/okanye imethane (CH4), amanzi (H2O) kunye nemineraliation yento equlathe ityuwa ye-inorganic, kunye ne-biomass entsha (efana nomzimba wemicroorganisms, njl.njl.) yeplastiki.
Ukuthelekiswa kweeplastiki ezininzi eziqhelekileyo ezinokubola
Imveliso kunye nokusasazwa kweeplastiki ze-biodegradable
Ngokwedatha yamva nje ekhutshwe yiEuropean Bioplastics Association ngoSeptemba ka-2019, ukusukela ngoSeptemba ka-2019, umthamo wehlabathi wonyaka wemveliso yeeplastiki ezinokuguquguquka.2144,000 iitoni;
I-PLA (i-polylactic acid) yaba628,000 iitoni, ukubalwa kwe29.3%;
I-PBAT (i-polyadipic acid / i-butylene terephthalate) yaba606,800 iitoni, ukubalwa kwe28.3%;
Iplastiki eyonakalayo esekwe kwisitatshi yaba96.27 iitoni, ukubalwa kwe44.9%yomthamo weplastiki enokubola kwihlabathi jikelele.

Imeko enokubola
Ukuthotywa komhlaba
I-PBAT, i-PHA, i-PCL kunye ne-PBS inokuthotywa ngokupheleleyo emva kweenyanga ezi-5.
Izinga lokuthotywa kwezinto ze-PLA licotha noko, kuphela yi-0.23% ngonyaka.
I-PLA kunye ne-PKAT inokuthotywa ngokupheleleyo malunga nesiqingatha sonyaka emva kokudibanisa.
Ukuthotywa kwamanzi
I-PHA kunye ne-PKAT inokuthotywa ngokupheleleyo kwiintsuku ezingama-30 ~ 60 phantsi kwemeko yokulinganisa yamanzi olwandle eyi-25℃±3℃.
