Hauv kev sib koom ua ke, SABIC, tus thawj coj hauv kev lag luam tshuaj lom neeg, Lamb Weston, tus tsim khoom lag luam thoob ntiaj teb ntawm cov qos yaj ywm khov, thiab Opackgroup, cov chaw tsim khoom ntawm cov yeeb yaj kiab hloov tau yooj yim, tau tsim cov ntim ruaj khov ua los ntawm bio-renewable polyethylene (PE) los ntawm kev siv. roj ua noj (UCO). Qhov kev pib no tsis tsuas yog txo cov kev cuam tshuam ib puag ncig nkaus xwb tab sis kuj qhia tau tias yuav ua li cas cov qauv kev lag luam ncig tuaj yeem siv rau kev ntim khoom noj.
Hauv plawv ntawm lub ntim tshiab yog kev siv bio-feedstock muab los ntawm UCO, sau ncaj qha los ntawm Lamb Weston cov txheej txheem ntau lawm. Cov khoom noj no hloov mus rau hauv Cov ntawv pov thawj bio-renewable SABIC® HDPE (high-density polyethylene) thiab SUPEER™ mLLDPE (metallocene linear low-density polyethylene) polymers, uas tsim lub hauv paus ntawm cov khoom ntim. Nrog tsawg kawg yog 60% ntawm cov khoom ntim khoom tsim los ntawm bio-based polymer, nws muaj cov kauj ruam tseem ceeb rau kev ntim khoom noj kom ruaj khov dua.
Lub resulting ntim nta a nyias coextrusion zaj duab xis qauv, txo nws qhov hnyav los ntawm 20%, nrog rau lub hnab hnyav qhov nruab nrab tsuas yog 10 grams. Txawm hais tias lub teeb yuag tsim, cov ntaub ntawv tuav lub zog siab thiab yoog raws, qhov tseem ceeb rau kev ntim khoom ua ntej kib cov qos yaj ywm. Qhov tseem ceeb, cov qauv no ua kom muaj ib qho 30% txo cov pa roj carbon hneev taw piv rau cov ntim khoom dhau los, ua raws li Lamb Weston lub hom phiaj kev ruaj ntseg ntawm kev txo cov khib nyiab, txiav cov pa roj carbon emissions, thiab txav mus rau cov txheej txheem ntau lawm los ntawm 2030.
Cov ntaub ntawv pov thawj kev ruaj ntseg ntawm kev ntim khoom muaj ntawv pov thawj hauv qab International Sustainability & Carbon Certification (ISCC) PLUS kev tswj hwm, ua kom pom tseeb ntawm qhov sib npaug ntawm cov ntsiab lus txuas ntxiv. Daim ntawv pov thawj ISCC PLUS taug qab cov ntsiab lus bio-renewable thoob plaws hauv cov saw hlau ntau lawm, muab cov neeg siv khoom thiab cov khw muag khoom muaj kev ntseeg siab tias lub ntim tau raws li cov qauv nruj nruj.
Khaled Al-Jalawi, Tus Thawj Saib Xyuas Kev Lag Luam Thoob Ntiaj Teb ntawm Kev Lag Luam Kev Lag Luam ntawm SABIC, tau hais txog qhov tseem ceeb ntawm kev sib koom tes no: "Qhov kev kaw lub voj voog no qhia txog kev lag luam ncig hauv kev nqis tes ua, hloov cov roj ua noj rau hauv cov khoom siv polymers rau kev ntim khoom ruaj khov. Nws qhia txog yuav ua li cas peb tuaj yeem siv cov khoom pov tseg zoo dua los tsim cov khoom lag luam zoo, rov ua dua tshiab. "
Kev tsim kho tshiab tseem ua rau muaj kev xav tau ntau ntxiv rau kev ntim khoom ruaj khov ntawm cov khw muag khoom thiab cov neeg siv khoom. Sebastian Brooms, VP Kev Lag Luam EMEA ntawm Lamb Weston, tau hais tias: "Cov neeg siv khoom tau paub ntau ntxiv txog lawv cov kev cuam tshuam ib puag ncig. Peb lub khw muag khoom bio-circular ntim, ua nrog 60% bio-renewable yas los ntawm peb cov roj ua noj, muab lub luag haujlwm tus nqi. Nws tsis tsuas yog txo cov pa roj carbon hneev taw ntawm peb lub hnab los ntawm 30%, tab sis kuj ua raws li cov neeg siv khoom xav tau rau cov khoom lag luam ib puag ncig. "
Tsis tas li ntawd, Laura Hanegraaf, Tus Thawj Saib Xyuas Muag Khoom ntawm Oerleman Plastics, tau qhia txog qhov cuam tshuam loj ntawm qhov kev txhim kho no hauv kev lag luam ntim khoom lag luam. Nws tau hais tias qhov project "ua kom muaj kev sib zog los txhawb cov khoom siv hluav taws xob tsawg thiab cov khoom siv txuas ntxiv dua tshiab. Kev sib koom tes tso cai rau peb muab cov neeg siv khoom zoo, hloov pauv cov khoom siv yeeb yaj kiab ua los ntawm cov khoom siv txuas ntxiv dua tshiab, ua kom muaj txiaj ntsig zoo rau kev ntim khoom. "
Cov ntaub ntawv siv hauv ntim tau raws li tag nrho European Food Safety Authority (EFSA) thiab US FDA cov khoom noj khoom haus-kev sib cuag, kom ntseeg tau tias lawv muaj kev nyab xeeb rau ntim cov khoom noj khov. Tom qab kev sim dav dav, thawj cov qos yaj ywm khov uas tau ntim rau hauv lub ntim bio-renewable no tau tsim tawm hauv Cuaj hlis 2024 nyob rau hauv ob qho tib si UK thiab Netherlands, kos npe rau qhov pib ntawm qhov zoo li yuav muaj kev loj hlob hauv kev lag luam khoom noj.
Kev koom tes ntawm SABIC, Lamb Weston, thiab Opackgroup sawv cev rau kev dhia mus rau kev ncig hauv kev lag luam ntim khoom noj. Los ntawm kev hloov cov khoom pov tseg rau hauv cov khoom ntim khoom muaj txiaj ntsig, qhov kev pib no tsis tsuas yog txo cov kev cuam tshuam ib puag ncig tab sis kuj tseem muab cov kev daws teeb meem rau kev tsim khoom ruaj khov. Raws li cov neeg siv khoom thiab cov khw muag khoom xav tau kev hloov pauv hauv eco-phooj ywg, kev tsim kho tshiab zoo li no yog qhov tseem ceeb rau kev tsav lub hom phiaj kev lag luam khoom noj kom ruaj khov mus tom ntej. Kev siv bio-renewable polyethylene ua los ntawm kev siv roj ua noj yuav txo tau cov pa roj carbon hneev taw, txo cov khib nyiab, thiab txhawb kev lag luam ntau dua - muab txoj hauv kev meej rau kev tsim zaub mov ntsuab thiab kev ntim khoom.
