Abahlobo abaninzi babuza ukuba yintoni umahluko phakathi kweengxowa zokupakisha ezihlekisayo kunye neengxowa zokupakisha ngokupheleleyo? Ngaba ayifani nebhegi yephakheji ehlekisayo? Ayilunganga, kukho umahluko phakathi kweengxowa zokupakishwa kwephakheji enobungozi kunye neengxowa zokupakisha ngokupheleleyo.
Iingxowa zokupakisha ezihlaselweyo, intsingiselo kukuba zinokuhlaselwa, kodwa iingxowa zephakheji ezihleliweyo zahlulahlulwe zaba "ngxaki" kwaye "ziyabonakala ngokupheleleyo". Yintoni umahluko? Qhubeka nokufunda ulwazi oluncinci olunikezwe ngu-Aneru.
Iingxowa zokupakisha ezinobungozi zibhekisa ukongeza inani elithile lezongezo (ezinjengesitabhi, isitatshi esiguquliweyo okanye ezinye iiselselensise, iifoto, i-biodegradants, njl.).
Ingxowa yokupakisha ngokupheleleyo ithethwayo kuthetha ukuba ibhegi yokupakisha yeplastiki ichithwayo incitshiswe ngokupheleleyo emanzini kunye nekharbon diokside. Owona mthombo wezinto ezinqabileyo ngokupheleleyo ziqwalaselwa kwingqolowa, i-cassava, njl njl. Kwi-lactic acid, eyi-PLA. I-Polylactic Acid (i-Pla) luhlobo olutsha lwezinto eziphilayo nezingenakufikeleleka. Izinto ezifudula ziluhlaza ziselungeleleki ukuba zifumane iglucose, emva koko zahlulwe kwiglucose kunye neentlobo ezithile zokuvelisa i-acid ecocekileyo ye-lactic, emva koko idityaniswe ngeendlela zeSynthesic. Imolekyuli yemolekyuli ye-molylactic acid. Inomgangatho ofanelekileyo we-biodeodiance, kwaye inokutshabalaliswa ngokupheleleyo zii-microorganisms kwindalo phantsi kweemeko ezithile emva kokusetyenziswa, ngaphandle kwe-carbon diokside namanzi, ngaphandle kokungcolisa indalo esingqongileyo kwaye yinto enobuhlobo obusingqongileyo. Okwangoku, izinto eziphambili ezisekwe kwingxowa yephakheji ehlekisayo ngokupheleleyo yenziwa nge-pla + i-PBAT, enokubakho ngokupheleleyo kwiinyanga ezi-3-6 kwiinyanga ezi-3-6 nge-Degrees (ngaphandle kongcoliseko kwindalo esingqongileyo.
Kutheni le nto i-pbat yongezwa? Injineli yokuvavanya ye-Anerui yanceda umhleli ukuba ayitolika. I-PBAT yi-copolymer ye-adipic acid, i-1,4-bleidiol kunye ne-terefecalic acid. I-synthesis yekhemikhali enokuthi ibe yi-biogradgrad. I-Aliific-i-Polymer ye-Aliititic-ivumba le-PBAT iguquguquka ibalaseleyo kwaye inokusetyenziselwa ifilimu yokuphuma kwefilimu, ukubetha, ukungqubana, ukubhalwa kweenkqubo zokubumba. Injongo yokudibanisa i-PLA kunye ne-PBAT kukuphucula ubunzima, bidegradiation kunye nokubumba ukunyuka kweplani. Iplani kunye ne-PBAT ayingqinelani, ke ukukhetha i-ateratizer efanelekileyo inokuphucula kakhulu ukusebenza kweplani.
Jonga apha ukuba uqonde umahluko phakathi kweengxowa zokupakishwa kwephakheji kunye neengxowa zokupakisha ngokupheleleyo.

Kutheni le nto i-pbat yongezwa? Abavelisi bephakethe obuguqukayo abaguqukayo balapha ukuchaza ukuba i-PBAT yi-Copolymer ye-AdiPic Acid, i-1,4-bheefdiol, kunye ne-Terephthayil Atid, enamafutha amnandi enokubakho ngokupheleleyo. I-Aulematic-i-pulymer ye-Aromatic, i-PBAT iguquguquka iguquguqukayo kwaye inokusetyenziselwa ifilimu yokuphuma kwefilimu, ukubetha ukubumba, ukubhalwa kwendlela yokubumba. Injongo yokudibanisa i-PLA kunye ne-PBAT kukuphucula ubunzima, bidegradiation kunye nokubumba ukunyuka kweplani.
