Qhov xoom- khib nyiab tau ua rau cov hnab ntaub ua khoom noj khoom haus loj. Tab sis ntau tus neeg nyob hauv lub zej zog nyob ruaj khov tseem tsis meej pem. Rau ntau tus neeg siv khoom "organic" daim ntawv lo txhais tau tias cov khoom tuaj yeem rov qab los rau hauv av. Qhov no yog qhov yuam kev loj. "Organic" tsuas yog txhais tau tias ua liaj ua teb siv tshuaj tua kab thiab chiv li cas. Nws tsis qhia seb cov khoom puas decomposes hauv av los yog ua compost. Paub sebOrganic Reusable Produce Bagstuaj yeem ua tau composted, peb yuav tsum tau saib ntawm textile science, tshuaj kho cov cai thiab kev tswj cov khib nyiab. Qhov no yog qhov tseem ceeb vim tias muab cov khoom siv tsis zoo hauv cov av tuaj yeem ua rau microplastics thiab cov tshuaj tsis zoo. Qhov no tuaj yeem cuam tshuam cov hom phiaj ib puag ncig uas cov neeg siv saib xyuas.
Kawm txog cov ntaub ntawv siv los ua cov hnab yas rov siv tau
Txhawm rau ntsuas nws cov qauv, koj yuav tsum xub saib dhau nws cov fibers tseem ceeb hauv lub hnab. Cov khoom xyaw feem ntau yog cov paj rwb organic, linen thiab hemp. Los ntawm kev xav txog kev noj qab haus huv, cov cellulose fibers yog cov zaub mov tiag tiag rau cov av microbes. Tsis kho hemp thiab linens muaj natural antimicrobial zog thiab muaj zog fiber ntau. Lawv tawg zoo, tawm hauv tsis muaj hluavtaws residue. Tab sis cov txheej txheem los ntawm kev ua liaj ua teb mus rau lub hnab tiav feem ntau ntxiv ob peb yam ntxiv uas hloov cov txiaj ntsig ntuj no.
Kev ua yog qhov tseem ceeb tsis paub. Txawm hais tias paj rwb tau loj hlob yam tsis muaj tshuaj tua kab, tom qab cov kauj ruam xws li ntxuav, tshuaj dawb thiab dyeing tuaj yeem siv cov hlau hnyav, formaldehyde-raws li fixatives lossis lwm yam tshuaj tsis tu ncua. Thaum cov hnab ntim faus, lawv tsis ploj. Lawv nkag mus rau hauv compost, tej zaum yuav ua mob microbes los yog paug cov nroj tsuag yav tom ntej. Tsis tas li ntawd, cov neeg yuav khoom hauv tsev yuav tsum kuaj xyuas tag nrho lub hnab. Lub hnab ua los ntawm 100% organic paj rwb ntaub tsis tsim nyog yog tias lawv sewn nrog polyester xov, muaj nylon drawstring los yog muaj ib tug yas-coated brand label. Thaum saibOrganic Reusable Produce Bags, qhov zoo ntawm txhua qhov tseem ceeb dua li cov lus tshaj tawm ua ntej. Daim ntawv pov thawj xws li Ntiaj Teb Organic Textile Standard (GOTS) muab kev ntsuas kev nyab xeeb los ntawm kev txwv cov khoom siv phom sij thaum ua haujlwm. Tab sis txawm tias GOTS- cov khoom muaj ntawv pov thawj yuav tsum tau kuaj xyuas lawv cov xwm txheej tshwj xeeb. Qhov no yog vim tias tus qauv tsom feem ntau ntawm cov ntsiab lus ntawm cov organic fiber ntau thiab cov kev cai ntawm kev sib raug zoo, tsis yog tus nqi ntawm cov khoom tawg thaum kawg ntawm lawv lub neej [1].
Yuav ua li cas Composites txawv ntawm ib txwm reusable ntim
Qhov sib txawv ntawm lub hnab ntim khoom thiab lub hnab ntim khoom ib txwm siv tau yog nws lub hom phiaj tsim qauv. Cov hnab yas qub yog tsim los ntawm nylon, polyester lossis siv PET thiab muaj zog txaus kom tsis txhob tawg hauv ib puag ncig. Lawv cov qauv molecular yog tsim los ua dej- tiv taus, tiv taus lub hnub puas tsuaj thiab tuaj yeem tiv taus ntau xyoo ntawm lub cev. Thaum cov ntaub ntawv no thaum kawg ncav cuag lawv lub neej muaj txiaj ntsig, lawv tawg mus rau hauv microplastics es tsis yog biomass. Kev ntsuam xyuas lub neej qhia tau hais tias thaum cov khoom siv hluavtaws ua haujlwm tau zoo nyob rau hauv "siv theem", lawv cov theem pov tseg muaj qhov tseem ceeb ntev -cov nqi ib puag ncig [2].
Cov ntaub hluavtaws tiag tiag, ntawm qhov tod tes, yog tsim los rhuav tshem ntawm qib molecular. Lawv vam khom cov enzymes microbial los hloov cellulose rau hauv carbon dioxide, dej thiab humus nyob rau hauv ib lub sij hawm teev. Qhov no yog kev lag luam tawm - tawm. Compostable hnab feem ntau tsis muaj cov waterproofing, stain kuj los yog tensile zog hluavtaws hnab. Cov neeg siv khoom xaivOrganic Reusable Produce Bagsnrog cov ntaub ntawv pov thawj compostability yog ib qho kev xaiv meej rau rov ua dua lub neej ntev. Qhov kev xaiv no yog nyob rau hauv txoj kab nrog regenerative xav. Tab sis nws kuj txhais tau hais tias lees txais lub neej luv luv thiab kev saib xyuas sib txawv dua li cov kev xaiv ua ke.
Yam tseem ceeb hauv kev txiav txim siab seb lub hnab ntim khoom puas yog compostable
Lub synthesis ntawm cov ntaub ntawv tsis yog ib tug ruaj zoo. Qhov no yog qhov tshwm sim uas yuav tsum tau ua pov thawj ntawm rooj plaub- los ntawm - rooj plaub. Peb yam tseem ceeb yog qhov tsim nyog.
Ua ntej, thib peb - tog neeg authentication yog yuav tsum tau. Cov lus zoo li "biodegradable" yog qhov tsis raug cai thiab tsis meej hauv kev tshawb fawb. Tab sis "compostable" ntawv pov thawj, xws li BPI, OK Compost los yog AS 4736, xyuas kom tiav tsis ua hauj lwm thiab ecotoxicity kev nyab xeeb raws li cov qauv xeem [3]. Yog tsis muaj pov thawj no, ib qho kev thov yog speculation. RauOrganic Reusable Produce Bags, nrhiav cov ntawv pov thawj tshwj xeeb no yog tib txoj hauv kev txhim khu kev qha los txheeb xyuas cov ntawv thov compostability.
Qhov thib ob, qhov twg koj muab nws txiav txim seb nws puas ua haujlwm. Feem ntau cov ntawv pov thawj textile compostability tsuas yog lees paub qhov ua haujlwm tsis zoo ntawm cov chaw tsim khoom. Kub hauv cov chaw no nyob nruab nrab ntawm 50 thiab 60 degrees Celsius, nrog cov av noo thiab huab cua tswj. Cov pawg hauv tsev tsis tshua muaj peev xwm ncav cuag qhov no. Nyob rau hauv ib qho chaw ua lag luam, ib lub hnab ntim organic paj rwb tuab tuaj yeem tawg tag nrho hauv 90 hnub. Tab sis nws tuaj yeem zaum hauv lub tiaj nraum qaum tsev tau ntau xyoo. Yog hais tias ib tug neeg ua txhaum nws rau cov compost tiav, nws yuav yog ib qho teeb meem ntawm kev sib kis.
Thib peb, tshuaj purity yog tsim nyog. Txhua PFAS, hluavtaws dye lossis resin coatings yog ib qho nyuaj thaiv uas tiv thaiv kev nyab xeeb composting. Cov tshuab khib nyiab tam sim no tab tom kawm cov khoom ntxiv no kom ze dua. Qhov no yog vim hais tias lawv tuaj yeem nyob ntev thiab sib sau ua ke hauv cov kab mob. Yog li ntawd, tsis yog tag nrhoOrganic Reusable Produce Bagsmuag li eco-phooj ywg yog compost tus phooj ywg. Tsuas yog cov uas muaj daim ntawv ntsuam xyuas ntawm tag nrho cov khoom tuaj yeem ntseeg tau.
Cov txiaj ntsig thiab kev txwv ntawm kev siv Compostable Organic Product Bags
Cov hnab ntim khoom sib xyaw muaj qhov pom tseeb zoo yog tias ua haujlwm raug. Lawv tiv thaiv cov hluavtaws fibers kom tsis txhob kis kab mob. Lawv kuj khaws ib zaug xwb - siv cov yas tawm ntawm qhov chaw pov tseg. Qhov twg muaj cov tshuab composting zoo, lawv kaw lub voj voog. Qhov no txhais tau hais tias cov pa roj carbon monoxide tuaj yeem rov qab mus rau hauv av es tsis nyob hauv qhov chaw pov tseg. Qhov no yog nyob rau hauv txoj kab nrog lub tswv yim ntawm kev lag luam ncig thiab yog qib siab tshaj plaws ntawm kev lag luam ruaj khov rau cov neeg siv khoom ib puag ncig.
Tab sis nws muaj kev txwv loj. Qhov tsawg dua nws yog, ntau zaus nws yuav tsum tau hloov. Cov txiaj ntsig ntawm ib puag ncig tuaj yeem raug them yog tias cov nqi ntawm kev tsim cov hnab yas tshiab tshaj tus nqi ntawm cov kauj ruam pov tseg. Nyiaj txiag kuj yog ib qho teeb meem. Certified compostable xaiv feem ntau kim dua vim hais tias lawv yuav tsum tau ntau stringent mov saw checks. Tej zaum qhov teeb meem loj tshaj plaws yog qhov sib txawv ntawm infrastructure. Qhov no tsim ib tug paradox. Certified biodegradable hnab yas xa mus rau qhov chaw pov tseg yog ib yam li cov khib nyiab tsis tu ncua. Nws tsim cov methane thiab tsis muaj cov khoom siv hauv av. Cov kev tshawb fawb tau pom tias cov txiaj ntsig ib puag ncig ntawm cov khoom ntim sib xyaw yog nyob ntawm qhov loj ntawm cov txheej txheem kho cov khib nyiab hauv zos thiab seb cov neeg siv khoom puas tau ua qhov raug [4]. Yog li opting rau compostableOrganic Reusable Produce Bagstsis yog ib qho kev xaiv zoo dua. Qhov kev txiav txim siab nyob ntawm qhov xwm txheej. Koj yuav tsum ua siab ncaj txog qhov koj siv cov hnab khib nyiab li cas thiab cov kev xaiv pov tseg muaj nyob ze.
Xaus
Cov lus teb rau seb cov organic, cov khoom siv rov qab siv tau cov hnab ntim khoom puas yog tsis yooj yim yog lossis tsis yog. Qhov no nyob ntawm plaub yam uas yuav tsum tau ua. Cov no yog ntuj fiber ntau purity, tsis yog -kev kuaj tshuaj lom neeg, official thib peb- ntawv pov thawj, thiab cov pov thawj raug. Cov neeg yuav khoom yuav tsum siv daim ntawv txheeb xyuas thaum yuav khoom. Lawv yuav tsum tau mus txog txhua feem ntawm cov khoom. Lawv yuav tsum tsis txhob cia siab rau cov lus tshaj tawm kev lag luam.
Rau cov neeg uas tsis tu ncua siv cov hnab khib nyiab thiab tsis muaj cov khib nyiab nyob ze, lub hnab khib nyiab ruaj khov uas siv ntau zaus yuav zoo dua li ib qho uas muab pov tseg ua ntej. Ntawm qhov tod tes, rau cov neeg uas muaj pov thawj txoj kev composting thiab tsuas yog siv lub hnab kom raug, ib qho pov thawj composting xaiv yog ib kauj ruam tiag tiag hauv lub voj voog khoom tiag. Thaum kawg, txhawm rau nqaim qhov sib txawv ntawm cov khoom thov thiab cov txiaj ntsig zoo ib puag ncig, kev lag luam yuav tsum qhib ntau dua. Tsis tas li ntawd, yuav tsum tau siv nyiaj ntau dua rau hauv lub nroog composting systems. Nyob rau hauv txoj kev no, zoo - cov ntsiab lus xaiv tuaj yeem xa cov txiaj ntsig zoo hauv zej zog uas lawv tau cog lus tseg.
