I-PBAT isondele kwimfezeko kuneepholima ezininzi Ⅱ

UJoerg Auffermann, iNtloko yeqela le-BASF biopolymers kwihlabathi jikelele loPhuhliso lweShishini, uthe: “Ezona nzuzo ziphambili ze-ikholoji yeeplastiki ezivundisiweyo zifika ekupheleni kobomi babo, njengoko ezi mveliso zinceda ukuguqula inkunkuma yokutya ukusuka kwiindawo zokulahla inkunkuma okanye izitshisi zibe yinto enokuphinda isetyenziswe.

Kwiminyaka edlulileyo, i-biodegradable polyester industry iye yafaka izicelo ngaphandle kweefilimu ezincinci. Kwi-2013, umzekelo, Inkampani yekhofi yaseSwitzerland yazisa ii-capsules zekhofi ezenziwe kwi-resin ye-Basf Ecovio.

Enye imarike evelayo yezinto zeNovamont yi-biodegradable tableware, enokuthi idityaniswe nezinye izinto eziphilayo. UFacco uthi oku kusikwa sele kubambekile kwiindawo ezifana neYurophu ethe yawisa imithetho ethintela ukusetyenziswa kweeplastiki ezisetyenziswa kanye.

Abadlali abatsha be-PBAT baseAsia bangena kwimarike belindele ukukhula okuqhutywa kokusingqongileyo. EMzantsi Korea, i-LG Chem yakha isityalo se-PBAT se-50,000-tonne ngonyaka esiya kuqalisa imveliso ngo-2024 njengenxalenye ye-2.2bn yesicwangciso sotyalo-mali esigxile ngokuzinzileyo eSeosan. I-SK Geo Centric (eyayisakuba yi-SK Global Chemical) kunye ne-Kolon Industries basebenzisana ukwakha iplanti ye-PBAT ye-50,000-toni eSeoul. I-Kolon, umenzi we-nylon kunye ne-polyester, ibonelela ngeteknoloji yokuvelisa, ngelixa i-SK inikezela ngezinto eziluhlaza.

I-PBAT yokuleqa igolide yayiyeyona inkulu eTshayina. I-OKCHEM, umthengisi weekhemikhali waseTshayina, ulindele ukuba imveliso ye-PBAT e-China inyuke ukusuka kwi-150,000 yeetoni ngo-2020 ukuya malunga neetoni ezingama-400,000 ngo-2022.

I-Verbruggen ibona inani labaqhubi botyalo-mali. Kwelinye icala, kuye kwakho ukwanda kwamva nje kwemfuno yazo zonke iintlobo ze-biopolymers. Unikezelo luqinile, ngoko ke ixabiso le-PBAT kunye ne-PLA liphezulu.

Ukongeza, uVerbruggen uthe, urhulumente waseTshayina ebetyhala ilizwe ukuba "likhule kwaye lomelele" kwi-bioplastics. Ebutsheni balo nyaka, ipasise umthetho ovala iingxowa zokuthenga ezingonakali, imiququ kunye nezinto ezisikiweyo.

UVerbruggen uthe imakethi ye-PBAT inomtsalane kubenzi beekhemikhali baseTshayina. Itekhnoloji ayintsonkothanga, ngakumbi kwiinkampani ezinamava kwipolyester.

Ngokwahlukileyo, i-PLA inemali eninzi kakhulu. Ngaphambi kokwenza ipolymer, inkampani kufuneka ivundise iasidi ye-lactic kumthombo weswekile eninzi. U-Verbruggen waphawula ukuba i-China "inentsilelo yeswekile" kwaye idinga ukungenisa i-carbohydrates. “I-China ayisiyondawo ilungileyo yokwakha amandla amaninzi,” utshilo.

Abavelisi be-PBAT abakhoyo bebesoloko behambelana nabadlali abatsha baseAsia. Ngo-2018, iNovamont yagqiba iprojekthi yokubuyisela kwakhona umzi-mveliso we-PET ePatrika, eItali, ukuvelisa i-polyester enokubola. Le projekthi iphinde yaphinda kabini imveliso yayo yepolyester enokubola yaya kutsho kwi-100,000 yeetoni ngonyaka.

Kwaye kwi-2016, i-Novamont yavula isityalo sokwenza i-butanediol kwiswekile isebenzisa iteknoloji yokuvutshelwa eyenziwe yiGenomatica. Isityalo esiziitoni ezingama-30,000 ngonyaka e-Itali sikuphela kohlobo lwaso ehlabathini.

NgokukaFacco, abavelisi abatsha be-PBAT baseAsia banokuvelisa inani eliqingqiweyo leelebhile zemveliso kwizicelo ezinkulu. “Akunzima.” Uthe. INovamont, ngokuchaseneyo, iya kugcina isicwangciso sayo sokusebenzela iimarike zeengcali.

I-Basf iphendule kwindlela yokwakhiwa kwe-PBAT yase-Asia ngokwakha isityalo esitsha e-China, ilayisenisi yeteknoloji ye-PBAT kwinkampani yaseTshayina i-Tongcheng New Materials, eceba ukwakha i-60,000-ton / year plant plant e-Shanghai ngo-2022. I-Basf iya kuthengisa isityalo iimveliso.

"Uphuhliso oluhle lweemarike kulindeleke ukuba luqhubeke kunye nemithetho emitsha ezayo kunye nemimiselo elawula ukusetyenziswa kwezinto ze-bioplastic ekupakisheni, ukuxubha kunye neengxowa," kusho u-Auffermann. Umatshini omtsha uya kuvumela i-BASF ukuba "ihlangabezane neemfuno ezikhulayo zommandla ukusuka kwinqanaba lendawo."

"Imarike kulindeleke ukuba iqhubeke nokuphuhlisa ngokufanelekileyo kunye nemithetho emitsha ezayo kunye nemimiselo elawula ukusetyenziswa kwezinto ze-bioplastic kwi-packaging, mulling kunye ne-bag applications," kusho u-Auffermann. Isibonelelo esitsha siza kuvumela i-BASF ukuba "ihlangabezane nemfuno ekhulayo kummandla".

Ngamanye amazwi, i-BASF, eyasungula i-PBAT phantse kwikota yenkulungwane eyadlulayo, ifumana ishishini elitsha elikhulayo njengoko i-polymer iba yinto eqhelekileyo.
