UJoerg Auffermann, iNhloko yethimba le-BASF biopolymers emhlabeni jikelele Lokuthuthukiswa Kwebhizinisi, uthe: “Izinzuzo eziyinhloko zemvelo zamapulasitiki afakwa umquba zifika ekupheleni kwezimpilo zabo, njengoba le mikhiqizo isiza ukuguqula imfucumfucu yokudla isuka ezindaweni zokulahla imfucumfucu noma izishisi ibe ukugaywa kabusha kwezinto eziphilayo.
Ngokuhamba kweminyaka, imboni ye-biodegradable polyester ifake izicelo ngaphandle kwamafilimu amancane. Ngo-2013, isibonelo, inkampani yekhofi yaseSwitzerland yethula amaphilisi ekhofi enziwe nge-Basf Ecovio resin.
Imakethe eyodwa esafufusa yezinto zokwakha zaseNovamont yi-biodegradable tableware, engahlanganiswa nezinye izinto eziphilayo. UFacco uthi lesi senzo sokusika sesiyasebenza ezindaweni ezifana ne-Europe eseziphasise imithetho evimbela ukusetshenziswa kwamapulasitiki asetshenziswa kanye.
Abadlali abasha be-PBAT base-Asia bangena emakethe ngokulindela ukukhula okwengeziwe okuqhutshwa yimvelo. ENingizimu Korea, i-LG Chem yakha isitshalo se-PBAT esingamathani angama-50,000 ngonyaka esizoqala ukukhiqizwa ngo-2024 njengengxenye yohlelo lokutshala imali olugxile ngokusimeme lwama-$2.2bn eSeosan. I-SK Geo Centric (ngaphambilini eyayaziwa ngokuthi i-SK Global Chemical) kanye ne-Kolon Industries zibambisene ukuze kwakhiwe imboni ye-PBAT engamathani angu-50,000 eSeoul. I-Kolon, umenzi wenayiloni ne-polyester, uhlinzeka ngobuchwepheshe bokukhiqiza, kuyilapho i-SK inikeza izinto zokusetshenziswa.
Ukugijima kwegolide kwe-PBAT bekukukhulu eShayina. I-OKCHEM, umsabalalisi wamakhemikhali waseShayina, ulindele ukuthi ukukhiqizwa kwe-PBAT eChina kukhuphuke kusuka kumathani ayi-150,000 ngo-2020 kuye kumathani angaba ngu-400,000 ngo-2022.
I-Verbruggen ibona abashayeli abaningi bokutshala izimali. Ngakolunye uhlangothi, kube nokwanda kwakamuva kwesidingo sazo zonke izinhlobo zama-biopolymers. Ukunikezwa kuqinile, ngakho intengo ye-PBAT ne-PLA iphezulu.
Ngaphezu kwalokho, uVerbruggen uthe, uhulumeni waseChina ubelokhu ecindezela izwe ukuthi "likhule futhi libe namandla" kuma-bioplastics. Ngasekuqaleni kwalo nyaka, iphasise umthetho ovimbela izikhwama zokuthenga ezingaboli, ama-straws nezinto zokusika.
U-Verbruggen uthe imakethe ye-PBAT iheha abenzi bamakhemikhali baseShayina. Ubuchwepheshe abuyona inkimbinkimbi, ikakhulukazi ezinkampanini ezinolwazi lwe-polyester.
Ngokuphambene, i-PLA inemali eningi kakhulu. Ngaphambi kokwenza i-polymer, inkampani idinga ukuvundisa i-lactic acid emthonjeni kashukela omningi. U-Verbruggen waphawula ukuthi i-China "inoshukela" futhi idinga ukungenisa ama-carbohydrate. "I-China akuyona ngempela indawo enhle yokwakha amandla amaningi," esho.
Abakhiqizi abakhona be-PBAT bebelokhu behambisana nabadlali abasha base-Asia. Ngo-2018, iNovamont yaphothula iphrojekthi yokubuyisela kabusha ifektri ye-PET ePatrika, e-Italy, ukuze kukhiqizwe i-polyester ebolayo. Le phrojekthi iphindaphinde kabili ukukhiqizwa kwayo kwe-polyester ebolayo ibe ngamathani ayi-100,000 ngonyaka.
Futhi ngo-2016, i-Novamont yavula isitshalo sokwenza i-butanediol kusuka kushukela isebenzisa ubuchwepheshe bokuvutshelwa obuthuthukiswe yi-Genomatica. Isitshalo esikhiqiza amathani angu-30,000 ngonyaka e-Italy yisona sodwa saso emhlabeni.
Ngokuka-Facco, abakhiqizi abasha be-PBAT base-Asia kungenzeka bakhiqize inani elilinganiselwe lamalebula omkhiqizo wezinhlelo zokusebenza ezinkulu. “Akunzima.” Wathi. INovamont, ngokuphambene, izogcina isu layo lokusebenzela izimakethe ezikhethekile.
I-Basf isabele enkambweni yokwakha yase-Asia ye-PBAT ngokwakha imboni entsha e-China, inikeze ilayisense ubuchwepheshe bayo be-PBAT enkampanini yaseShayina i-Tongcheng New Materials, ehlela ukwakha imboni yokukhiqiza engamathani angu-60,000/ngonyaka e-Shanghai ngo-2022. I-Basf izothengisa imboni imikhiqizo.
"Intuthuko yemakethe enhle kulindeleke ukuthi iqhubeke nemithetho nemithetho emisha ezayo elawula ukusetshenziswa kwezinto ze-bioplastic ekupakisheni, ekuhlanganiseni nasezikhwameni," kusho u-Auffermann. Lesi sikhungo esisha sizovumela i-BASF ukuthi "ihlangabezane nezidingo ezikhulayo zesifunda kusukela ezingeni lendawo."
"Imakethe kulindeleke ukuthi iqhubeke nokuthuthuka kahle ngemithetho emisha nemithethonqubo ezayo elawula ukusetshenziswa kwezinto ze-bioplastic ekufakweni, ekuhlanganiseni nasekufakeni izikhwama," kusho u-Auffermann. Isikhungo esisha sizovumela i-BASF ukuthi “ihlangabezane nesidingo esikhulayo esifundeni”.
Ngamanye amazwi, i-BASF, eyasungula i-PBAT cishe engxenyeni yesine yekhulu leminyaka edlule, ithola ibhizinisi elisha elichumayo njengoba i-polymer iba into evamile.
