Kwv yees li ntawm 8.3 billion tonnes ntawm yas tau tsim txij li thaum muaj kev lag luam tsim tawm hauv xyoo 1950.
Raws li kev tshawb fawb xyoo 2017, uas tseem pom tau tias tsuas yog 9% ntawm cov yas no tau siv dua tshiab, qhov no yog qhov teeb meem.12% ntawm cov khib nyiab uas tsis tuaj yeem rov ua dua yog hlawv, thiab cov seem ua rau ib puag ncig los ntawm kev muab pov tseg rau hauv qhov chaw pov tseg.
Cov lus teb zoo tshaj plaws yuav yog txo qis kev siv cov yas ib zaug lossis ua kom cov khoom ntim khoom ruaj khov dua vim tias kev zam cov ntawv ntim khoom tsis yog ib txwm siv tau.
Cov khoom siv niaj hnub raug hloov los ntawm cov khoom siv rov siv tau lossis cov khoom siv hauv ecologically, xws li cov ntim kas fes compostable, hauv ntau qhov kev lag luam, suav nrog kev lag luam kas fes tshwj xeeb.
Lub thawv rau kas fes compostable, txawm li cas los xij, muaj cov khoom siv organic uas decomposes dhau sijhawm.Qee tus neeg hauv kev lag luam kas fes tau txhawj xeeb txog cov khoom lag luam txee lub neej vim li ntawd.Txawm li cas los xij, cov hnab kas fes compostable yog qhov muaj zog heev thiab ua haujlwm zoo ntawm kev khaws cov kas fes taum thaum khaws cia rau hauv txoj cai cia.
Kawm paub ntxiv txog kev ncua lub txee lub neej ntawm compostable kas fes ntim rau roasters thiab khw kas fes.
Lub ntim kas fes uas yog compostable yog dab tsi?
Kev lig kev cai, cov ntaub ntawv uas yuav decompose rau hauv lawv cov organic Cheebtsam nyob rau hauv qhov tseeb yog siv los ua compostable kas fes ntim.
Feem ntau, nws yog tsim nrog cov khoom siv txuas ntxiv dua tshiab xws li qab zib, pob kws, thiab pob kws.Thaum disassembled, cov khoom no tsis muaj kev cuam tshuam rau ib puag ncig.
Compostable ntim, uas feem ntau yog tsim los ntawm cov khoom siv organic, tau txais koob meej hauv cov khoom noj thiab dej haus.Qhov tseem ceeb, nws yog feem ntau siv los ntim thiab muag kas fes los ntawm cov khw tshwj xeeb roasters thiab kas fes cafes.
Compostable ntim yog txawv los ntawm lwm yam bioplastics vim nws tuaj nyob rau hauv ntau qhov ntau thiab tsawg, daim ntawv, thiab tsim.
Lo lus "bioplastic" yog hais txog ntau yam khoom.Nws tuaj yeem siv los piav qhia txog cov khoom siv yas ua los ntawm cov khoom siv biomass uas tuaj yeem rov ua dua tshiab, suav nrog zaub roj thiab roj.
Polylactic acid (PLA), uas yog compostable bioplastic, tshwj xeeb tshaj yog zoo nyiam nyob rau hauv kas fes kev lag luam.Qhov no yog vim lawv pab txo kev lag luam 'cov pa roj carbon hneev taw los ntawm kev tawm hauv qab dej, carbon dioxide, thiab biomass thaum lawv pov tseg kom raug.
Kev lig kev cai, fermented qab zib los ntawm cov hmoov txhuv nplej siab xws li pob kws, qab zib beet, thiab cassava pulps tau siv los ua PLA.Txhawm rau tsim PLA pellets, cov suab thaj uas tau muab tshem tawm yog fermented rau hauv lactic acid thiab tom qab ntawd mus rau txheej txheem polymerization.
Cov pellets no tuaj yeem siv los tsim cov khoom lag luam ntxiv, suav nrog cov fwj thiab cov khoom siv kho mob biodegradable xws li cov ntsia hlau, pins, thiab cov pas nrig, los ntawm kev sib txuas nrog cov thermoplastic polyester.
PLA qhov teeb meem zoo thiab cov khoom siv hluav taws xob ua rau nws yog cov khoom siv zoo tshaj plaws rau ntim kas fes.Tsis tas li ntawd, nws muaj cov pa oxygen barrier uas zoo ib yam li cov pa thermoplastics.
Cov phom sij tseem ceeb rau kas fes tshiab yog cov pa oxygen thiab cua sov ua ke nrog cov dej noo thiab lub teeb.Yog li ntawd, kev ntim khoom yuav tsum txwv cov ntsiab lus no los ntawm kev cuam tshuam thiab muaj feem cuam tshuam cov taum sab hauv.
Yog li ntawd, feem ntau lub hnab kas fes xav tau ntau txheej los tiv thaiv thiab khaws kas fes tshiab.Kraft daim ntawv thiab PLA liner yog cov khoom siv feem ntau ua ke rau kev ntim kas fes compostable.
Kraft daim ntawv yog compostable kiag li thiab complements lub minimalist style uas ntau lub khw kas fes nyiam xaiv.
Kraft daim ntawv kuj tseem tuaj yeem txais cov ntawv ntim dej thiab siv rau hauv cov txheej txheem luam ntawv digital niaj hnub, ob qho tib si uas muaj kev nyab xeeb ntau dua.
Compostable ntim tej zaum yuav tsis tsim nyog rau cov lag luam tab tom nrhiav kom lawv cov khoom tshiab rau lub sijhawm ntev, tab sis nws yog qhov zoo tagnrho rau kas fes tshwj xeeb.Qhov no yog vim qhov tseeb tias PLA yuav ua haujlwm ntev txog ib xyoos ua raws nraim tib yam li cov khoom siv polymers.
Nws tsis yog qhov xav tsis thoob tias cov roasters thiab kas fes cafes tau mob siab rau siv cov ntim kas fes compostable hauv ib qho chaw uas cov neeg siv khoom feem ntau ua qhov tseem ceeb rau kev ruaj ntseg.
Lub ntim kas fes compostable yuav kav ntev npaum li cas?
Ntim uas yog compostable yog tsim nyob rau hauv ib txoj kev uas tsuas yog tej yam kev mob yuav ua rau nws mus decompose.
Nws xav tau qhov tsim nyog microbiological ib puag ncig, cov pa oxygen thiab noo noo, sov so, thiab lub sijhawm ntev heev kom decompose.
Tsuav nws khaws cia txias, qhuav, thiab qhov cua zoo, nws tseem yuav muaj zog thiab muaj peev xwm tiv thaiv taum kas fes.
Yog li ntawd, cov xwm txheej tsim nyog rau nws degrade yuav tsum tau ua tib zoo tswj.Vim li no, qee qhov ntim ntim compostable yuav tsis tsim nyog rau composting hauv tsev.
Hloov chaw, PLA-lined compostable kas fes ntim yuav tsum muab pov tseg rau hauv lub thawv ntim khoom tsim nyog thiab coj mus rau qhov chaw tsim nyog.
Piv txwv li, UK tam sim no muaj ntau dua 170 qhov chaw tsim khoom siv hauv tsev.Kev npaj rau cov neeg siv khoom kom rov qab ntim cov khoom pov tseg rau lub tsev noj mov lossis khw kas fes yog lwm txoj haujlwm uas tau txais kev nyiam.
Cov tswv tuaj yeem lav tias lawv tau muab pov tseg kom zoo.Origin Coffee yog ib lub tsev noj mov hauv UK uas ua tau zoo ntawm qhov no.Nws tau ua kom yooj yim los sau nws cov khoom ntim khoom lag luam biodegradable pib txij xyoo 2019.
Tsis tas li ntawd, txij li Lub Rau Hli 2022, nws tsuas yog siv 100% lub tsev ntim kas fes biodegradable, txawm hais tias kev sau kerbside tseem tsis tuaj yeem ua nrog qhov no.
Yuav ua li cas cov roasters ua rau lawv cov compostable kas fes ntim kav ntev?
Hauv cov ntsiab lus, ntim kas fes compostable yuav tsum muaj peev xwm khaws cov kas fes roasted rau cuaj mus rau kaum ob lub hlis nrog me ntsis kom tsis txhob muaj qhov tsis zoo.
Compostable PLA-lined kas fes hnab tau pom tias muaj kev cuam tshuam zoo dua qub thiab kev khaws cia tshiab hauv kev sim piv rau cov ntim tshuaj petro.
Tshaj li 16 lub lis piam, cov tub ntxhais kawm ntawv tau tso cai Q tau ua haujlwm nrog kev sim kas fes khaws cia hauv ntau hom hnab.Lawv kuj tau qhia kom ua qhov muag tsis pom kev thiab tau qhab nia tshiab ntawm cov khoom raws li ntau tus yam ntxwv tseem ceeb.
Raws li kev tshawb pom, cov compostable hloov pauv khaws cov tsw thiab tsw zoo ib yam li lossis zoo dua.Lawv kuj pom tias cov acidity NW nyuam qhuav txo qis rau lub sijhawm ntawd.
Cov kev cia zoo sib xws siv rau cov ntim kas fes compostable thaum lawv ua rau kas fes.Nws yuav tsum tau khaws cia tawm ntawm tshav ntuj ncaj qha hauv qhov chaw txias, qhuav.Roasters thiab kas fes lag luam yuav tsum nco ntsoov txhua yam ntawm cov ntsiab lus no thaum khaws cov hnab kas fes.
Txawm li cas los xij, PLA-lined hnab xav tau kev saib xyuas tshwj xeeb vim lawv tuaj yeem degrade sai dua nyob rau hauv ib qho ntawm cov xwm txheej no.
Compostable ntim tuaj yeem pab txhawb lub tuam txhab lub hom phiaj kev ruaj ntseg thiab thov kom muaj tus lej ntawm cov neeg siv khoom zoo ib puag ncig yog tias khaws cia kom raug.
Qhov tseem ceeb ntawm no, nrog rau ntau yam ntawm cov khw muag khoom kas fes, yog qhia rau cov neeg siv khoom ntawm kev coj ua tsim nyog.Txhawm rau khaws cov kas fes tshiab, roasters muaj kev xaiv ntawm cov ntawv luam tawm digitally yuav ua li cas khaws cov hnab kas fes compostable.
Tsis tas li ntawd, lawv tuaj yeem qhia cov neeg siv khoom txog yuav ua li cas thiab qhov twg kom rov ua dua lawv lub hnab PLA-kab los ntawm kev qhia lawv qhov chaw pov tseg.
Ntawm Cyan Pak, peb muab ib puag ncig tus phooj ywg ntim rau kas fes roasters thiab khw kas fes uas yuav tiv thaiv koj kas fes los ntawm lub teeb raug thiab ua kom pom koj txoj kev mob siab rau kev ruaj khov.
Peb cov nplej ntau ntau lossis kraft daim ntawv hnab siv PLA laminates los tsim kev thaiv ntxiv rau cov pa oxygen, lub teeb, cua sov, thiab noo noo thaum tswj lub ntim cov khoom siv rov ua dua tshiab thiab cov khoom siv compostable.
Tiv tauj peb kom paub meej ntxiv txog kev ntim kas fes compostable.
