Cov dej hiav txwv-phooj ywg "tso tseg tsis muaj residue" biodegradable hnab

Ua los ntawm PVA, dej hiav txwv-phooj ywg "tso tseg" biodegradable hnab tuaj yeem muab pov tseg los ntawm kev yaug nrog dej sov lossis dej kub.
British outerwear brand Finisterre lub hnab khaub ncaws tshiab tau hais tias txhais tau tias "tso tseg tsis muaj kab". Thawj lub tuam txhab hauv nws txoj kev lag luam tau txais daim ntawv pov thawj B Corp (ib daim ntawv pov thawj uas ntsuas lub tuam txhab kev ua tau zoo tag nrho thiab tsim cov khoom lag luam hauv lub luag haujlwm thiab ruaj khov.
Finisterre yog nyob rau ntawm lub pob tsuas saib lub hiav txwv Atlantic hauv St Agnes, Cornwall, England. Nws cov khoom muaj xws li cov khaub ncaws sab nrauv mus rau cov khoom tshwj xeeb xws li knitwear, rwb thaiv tsev, khaub ncaws tsis muaj dej thiab cov khaubncaws sab nraud povtseg "tsim rau kev taug txuj kev nyuaj thiab evoking kev hlub ntawm hiav txwv." Yog li hais tias Niamh O'Lagre, tus thawj coj ntawm kev tsim khoom thiab thev naus laus zis ntawm Finisterre, uas ntxiv tias qhov kev ntshaw rau kev tsim kho tshiab yog nyob rau hauv lub tuam txhab DNA. "Nws tsis yog hais txog peb cov khaub ncaws," nws hais. "Qhov no siv rau txhua qhov chaw ntawm kev lag luam, suav nrog kev ntim khoom."
Thaum Finisterre tau txais daim ntawv pov thawj B Corp hauv xyoo 2018, nws tau cog lus tias yuav tshem tawm ib leeg-siv, tsis yog biodegradable plastics los ntawm nws cov saw hlau. Oleger hais tias "Plastic yog nyob txhua qhov chaw," Oleger hais. "Nws yog ib yam khoom muaj txiaj ntsig zoo thaum nws lub neej voj voog, tab sis nws txoj kev ua neej ntev yog qhov teeb meem. Nws tau kwv yees tias 8 lab tons ntawm cov yas nkag rau hauv dej hiav txwv txhua xyoo. Nws tau xav tias muaj microplastic nyob hauv dej hiav txwv tam sim no dua li muaj nyob hauv cov hnub qub ntawm Milky Way. " ntau”.
Thaum lub tuam txhab kawm txog biodegradable thiab compostable yas xa khoom Aquapak, O'Lagre hais tias lub tuam txhab tau nrhiav lwm txoj hauv kev rau cov hnab yas khaub ncaws rau qee lub sijhawm. "Tab sis peb nrhiav tsis tau cov khoom tsim nyog kom tau raws li tag nrho peb cov kev xav tau," nws piav qhia. "Peb xav tau cov khoom lag luam nrog ntau qhov kev daws teeb meem kawg ntawm lub neej, siv tau rau txhua tus neeg siv khoom (cov neeg siv khoom, cov khw muag khoom, cov chaw tsim khoom) thiab, qhov tseem ceeb tshaj plaws, yog tias tso tawm rau hauv ib puag ncig ntuj, nws yuav ua rau tag nrho thiab tsis muaj qhov seem. Ua nrog microplastics.
Polyvinyl cawv technical resins Aquapak Hydropol ua tau raws li tag nrho cov kev cai no. PVA, tseem hu ua PVA, yog lub ntuj, dej-soluble thermoplastic uas yog biocompatible thiab tsis muaj tshuaj lom. Txawm li cas los xij, ib qho tsis zoo ntawm cov khoom ntim yog thermal instability, uas Aquapak hais tias Hydropol tau hais.
"Tus yuam sij rau kev tsim kho lub npe nrov tshaj plaws ua haujlwm polymer no nyob rau hauv cov tshuaj ua haujlwm thiab cov khoom siv ntxiv uas tso cai rau kev tsim cov khoom siv hluav taws xob uas kho tau Hydropol, tsis zoo li keeb kwm PVOH systems, uas muaj peev xwm siv tsawg heev vim thermal instability," said Dr. John Williams, Chief Technical Officer tus thawj coj ntawm lub tuam txhab Aquapack. "Qhov kev ua tau zoo sib xws no qhib rau kev ua haujlwm - lub zog, kev thaiv, qhov kawg ntawm lub neej - rau kev lag luam ntim khoom loj, tso cai rau kev tsim cov ntim khoom tsim uas yog ob qho tib si ua haujlwm thiab rov ua dua / biodegradable. Ua tib zoo xaiv cov cuab yeej siv thev naus laus zis tshwj xeeb tswj biodegradability hauv dej. "
Raws li Aquapak, Hydropol dissolves tag nrho hauv dej sov, tsis muaj qhov seem; resistant rau ultraviolet hluav taws xob; muab kev tiv thaiv kev tiv thaiv roj, roj, roj, roj thiab petrochemicals; breathable thiab noo noo resistant; muab cov pa oxygen barrier; ruaj thiab puncture resistant. hnav thiab nyab xeeb rau dej hiav txwv, tag nrho biodegradable nyob rau hauv marine ib puag ncig, nyab xeeb rau marine nroj tsuag thiab tsiaj qus. Dab tsi ntxiv, Hydropol tus qauv hlaws zoo txhais tau tias nws tuaj yeem ncaj qha mus rau hauv cov txheej txheem tsim khoom uas twb muaj lawm.
Dr. Williams tau hais tias Finisterre qhov yuav tsum tau ua rau cov khoom siv tshiab yog tias nws muaj kev nyab xeeb hauv dej hiav txwv, pob tshab, luam tau, ruaj khov thiab ua tau zoo ntawm cov khoom siv uas twb muaj lawm. Txoj kev txhim kho rau Hydropol-raws li lub hnab ris tsho siv yuav luag ib xyoos, suav nrog kev kho cov solubility ntawm cov resin kom haum raws li qhov xav tau ntawm daim ntawv thov.
Lub hnab kawg, hu ua "Tawm Tsis Taug Kev" los ntawm Finisterre, yog tsim los ntawm Aquapak's Hydropol 30164P ib leeg ply extrusion zaj duab xis. Cov ntawv nyeem ntawm lub hnab pob tshab piav qhia tias nws yog "Dej soluble, dej hiav txwv nyab xeeb thiab biodegradable, degrading harmlessly hauv av thiab dej hiav txwv kom tsis muaj tshuaj lom biomass."
Lub tuam txhab qhia nws cov neeg siv khoom hauv nws lub vev xaib, "Yog tias koj xav paub yuav ua li cas pov tseg cov hnab ntim tsis muaj kab, txhua yam koj xav tau yog lub kais dej thiab lub dab dej. Cov khoom tawg sai sai ntawm cov dej kub siab tshaj 70 ° C. thiab tsis muaj teeb meem. Yog tias koj lub hnab xaus rau hauv qhov chaw pov tseg, nws biodegrades ib txwm muaj thiab tsis muaj qhov seem. "
Cov pob khoom kuj tuaj yeem rov ua dua tshiab, ntxiv rau lub tuam txhab. "Cov khoom no tuaj yeem txheeb xyuas tau yooj yim siv txoj hauv kev txheeb xyuas xws li infrared thiab laser sorting, yog li nws tuaj yeem raug cais thiab rov ua dua tshiab," lub tuam txhab piav qhia. "Nyob hauv cov chaw kho cov khib nyiab tsawg dua, cov dej kub yaug tuaj yeem ua rau Hydropol yaj. Ib zaug hauv cov tshuaj, cov polymer tuaj yeem rov ua dua, lossis cov tshuaj tuaj yeem mus rau kev kho dej khib nyiab lossis kev zom zaub mov anaerobic. "
Finisterre lub hnab xa ntawv tshiab yog sib dua li lub hnab ntawv kraft nws siv ua ntej, thiab nws cov yeeb yaj kiab thaiv yog tsim los ntawm Aquapak's Hydropol cov khoom. Tom qab Lub Hnab Tsis Muaj Kab Ntsig, Finisterre tau qhia txog qhov kev pabcuam xa ntawv tshiab thiab sib dua uas hloov cov hnab ntawv hnyav hnyav uas nws siv los xa nws cov khoom. Lub pob tau tsim los ntawm Finisterre hauv kev koom tes nrog Aquapak thiab recycler EP Group. Lub pob, tam sim no hu ua Flexi-Kraft mailer, yog ib txheej ntawm Hydropol 33104P tshuab zaj duab xis laminated rau kraft ntawv siv cov kua nplaum tsis muaj kuab lom. Cov txheej Hydropol tau hais kom muab lub hnab muaj zog, yoog raws thiab tsim kua muag. PVOH txheej kuj ua rau lub hnab sib zog dua li cov hnab ntawv xa ntawv yooj yim thiab tuaj yeem ua kom sov rau lub foob kom muaj zog dua.
"Siv 70% cov ntawv tsawg dua li peb lub hnab qub, lub pob tshiab no laminates cov ntawv hnyav nrog peb cov khoom siv dej-soluble soluble los tsim lub hnab ruaj khov uas tuaj yeem muab ntxiv rau koj cov ntawv rov ua dua lub neej, nrog rau cov ntaub ntawv rov ua dua tshiab rau hauv. txheej txheem pulping. " - tshaj tawm hauv lub tuam txhab.
"Liab peb lub hnab xa ntawv nrog cov khoom tshiab no, txo lub hnab hnyav li 50 feem pua ​​​​thaum ua kom cov ntawv muaj zog los ntawm 44 feem pua, tag nrho thaum siv cov khoom siv tsawg," lub tuam txhab ntxiv. "Qhov no txhais tau hais tias tsawg dua cov peev txheej tau siv hauv kev tsim khoom thiab thauj khoom."
Txawm hais tias kev siv Hydropol muaj kev cuam tshuam loj rau tus nqi ntawm Finisterre lub ntim khoom (plaub mus rau tsib npaug siab dua polyethylene nyob rau hauv cov ntaub ntawv ntawm cov khaub ncaws hnab), O'Laogre hais tias lub tuam txhab kam lees txais cov nqi ntxiv. "Rau lub tuam txhab nrhiav kev lag luam zoo dua, qhov no yog qhov tseem ceeb heev uas peb ntseeg," nws hais. "Peb zoo siab heev los ua thawj lub tuam txhab tsoos tsho hauv ntiaj teb los siv cov tshuab ntim khoom no thiab peb tab tom ua kom nws qhib rau lwm lub npe uas xav siv nws vim tias ua ke peb tuaj yeem ua tiav ntau dua."
