Uphuhliso kunye nokuSetyenziswa kwePlastiki eBoneka

Inkcazo yeeplastiki ze-biodegradable, kukukhomba kwindalo, njengomhlaba, isanti, imo engqongileyo yamanzi, indawo yamanzi, iimeko ezithile ezinjengomgquba kunye neemeko zokwetyisa kwe-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 yi-European 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 zinokuthotywa ngokupheleleyo kwiintsuku ezingama-30 ~ 60 phantsi kwemeko yokulinganisa yamanzi olwandle eyi-25℃±3℃.
