Ngokwemithombo yezinto ezikrwada zeeplastiki ezinokuguquguquka, kukho iindidi ezimbini zeBiodegradable Plastics: iBio based and petrochemical based. I-PBAT luhlobo lwepetrochemical esekelwe kwi-biodegradable plastics.
Kwiziphumo zovavanyo lokuthotywa kwe-biodegradation, i-PBAT inokuthotywa ngokupheleleyo phantsi kweemeko zemozulu zesiqhelo kwaye ingcwatywe emhlabeni kangangeenyanga ezi-5.
Ukuba i-PBAT isemanzini olwandle, ii-microorganisms ezilungelelaniswe kwindawo enetyuwa ephezulu zikhona kumanzi olwandle. Xa ubushushu bungama-25 ℃ ± 3 ℃, bunokuthotywa ngokupheleleyo malunga neentsuku ezingama-30-60.
Iiplastiki ze-PBAT eziguquguqukayo ze-biodegradable zinokonakaliswa phantsi kweemeko zomgquba, ezinye iimeko ezifana nesixhobo sokwetyisa i-anaerobic, kunye nokusingqongileyo kwendalo okufana nomhlaba namanzi olwandle.
Nangona kunjalo, imeko ethile yokuthotywa kunye nexesha lokuthotywa kwe-PBAT zinxulumene nesakhiwo sayo sekhemikhali, ifomula yemveliso kunye neemeko zokuthotywa kokusingqongileyo.
