Nyob rau hauv ib lub sijhawm ntawm kev loj hlob ntawm ib puag ncig kev paub, kev lag luam zam tab tom muaj kev hloov pauv tseem ceeb. Ib lo lus uas koj yuav ntsib yog "cov khaub ncaws siv dua tshiab"Tab sis nws txhais li cas tiag? Nws yog ntau tshaj li tsuas yog pub cov khaub ncaws qub rau lub khw muag khoom noj khoom haus xwb. Cov khaub ncaws siv dua tshiab sawv cev rau cov txheej txheem tsim nyog thiab tseem ceeb ntawm kev txo cov khoom pov tseg thiab txuag cov peev txheej, tsim kom muaj kev lag luam zam ntau dua.
Ntawm nws lub hauv paus, cov khaub ncaws rov ua dua yog hais txog cov khaub ncaws ua los ntawm cov khoom uas tau rov qab los thiab rov ua dua los ntawm ua ntej - cov khoom uas twb muaj lawm lossis pov tseg. Cov txheej txheem no muab lub neej tshiab rau cov khoom siv uas yuav ua rau tsis zoo rau hauv qhov chaw pov tseg. Muaj ob txoj hauv kev tseem ceeb rau kev rov ua dua tshiab no, categorized los ntawm lawv cov khoom siv.
1. Tshaj tawm -Cov khoom siv rov ua dua tshiab
Qhov no yog hom kev rov ua dua tshiab uas tib neeg xav txog. Nws suav nrog kev sau thiab ua cov khoom uas cov neeg siv khoom tau siv thiab muab pov tseg.
Qhov chaw:Cov khaub ncaws qub, khau, khoom siv hauv tsev, thiab txawm lub raj mis yas.
Txheej txheem:Cov khoom plig thiab cov thawv ntim khoom sib sau ua ke - tawm khaub ncaws. Cov khoom no ces txheeb. Txawm hais tias qee qhov raug muag dua li cov khaub ncaws thib ob, cov khoom siv tsis tau raug coj mus rau cov khoom siv rov ua dua tshiab. Nyob ntawd, lawv tau txheeb los ntawm cov khoom siv thiab xim, stripped ntawm zippers thiab cov nyees khawm, thiab shredded rov qab mus rau hauv lub xeev fibrous. Cov khoom siv raw no tuaj yeem rov ua rau cov xov paj tshiab thiab woven lossis knitted rau hauv cov ntaub tshiab.
Piv txwv:Ib daim ntawv thov feem ntau yog xa cov fwj yas pov tseg (ua los ntawm PET) rau hauv polyester fiber. Cov yas yog ntxuav, shredded rau hauv flakes, melted, thiab extruded rau hauv zoo threads, uas yuav spun rau hauv xov paj los tsim fleece, sportswear, thiab lwm yam polyester-raws li ntaub.
2. Ua ntej-Cov khoom siv rov ua dua tshiab
Hom kev rov ua dua tshiab no tshwm sim ua ntej cov khoom lag luam mus txog tus neeg siv khoom. Nws suav nrog reclaiming pov tseg tsim thaum lub sij hawm tsim khoom.
Qhov chaw:Npuag scraps, txiav-chaw tawm- txiav, thiab cov xov paj tsis zoo los ntawm textile mills thiab garment factories.
Txheej txheem:Es tsis txhob muab pov tseg, cov khoom seem ntawm cov khoom lag luam no tau sau, muab txiav, thiab sib xyaw nrog cov fibers nkauj xwb los tsim cov ntaub ntawv tshiab. Qhov no yog ib txoj hauv kev zoo los txo cov khib nyiab ntawm qhov chaw.
Piv txwv:Ib lub t-tsho lub Hoobkas sau cov paj rwb cov ntaub uas seem tshuav los ntawm nws cov rooj txiav. Cov scraps no tau muab rov qab rau hauv cov paj rwb fibers (ib txoj kev hu ua garnetting) thiab tom qab ntawd rov ua dua tshiab, feem ntau sib xyaw nrog cov paj rwb tshiab lossis lwm cov fibers rau lub zog.
Cov txiaj ntsig ntawm kev xaiv cov khaub ncaws siv dua tshiab
Kev thawb rau kev rov ua dua tshiab yog tsav los ntawm nws cov txiaj ntsig zoo ib puag ncig:
Txo cov khib nyiab pov tseg:Kev lag luam zam yog ib qho tseem ceeb rau kev pov tseg thoob ntiaj teb. Cov khaub ncaws rov ua dua tau hloov ntau lab tons ntawm textiles los ntawm qhov chaw pov tseg txhua xyoo.
Conserves Natural Resources:Kev siv cov ntaub ntawv uas twb muaj lawm yuav txo tau qhov kev xav tau ntawm cov ntaub ntawv nkauj xwb. Piv txwv li, siv cov paj rwb rov qab txuag dej thiab tshuaj tua kab ntau, thaum siv polyester txo peb kev cia siab rau roj av.
Lowers Carbon Footprint:Kev tsim cov khoom siv rov ua dua tshiab feem ntau xav tau lub zog tsawg dua thiab ua rau qis qis hauv tsev cog khoom roj emissions piv rau kev tsim cov ntaub ntawv nkauj xwb los ntawm kos.
Txhawb Kev Lag Luam Kev Lag Luam:Cov khaub ncaws rov qab ua rau peb txav deb ntawm cov tsoos "coj- ua- pov tseg" cov qauv kab thiab mus rau ib lub voj voog uas cov ntaub ntawv khaws cia siv ntev li ntev tau.
Kev Sib Tw thiab Yav Tom Ntej
Thaum cog lus, cov khaub ncaws rov ua dua tshiab ntsib teeb meem. Mechanical recycling (shredding) tuaj yeem txo qhov ntev ntawm fiber ntau, qee zaum yuav tsum tau sib xyaw nrog cov fibers nkauj xwb. Tsis tas li ntawd, cov ris tsho ua los ntawm cov ntaub sib xyaw (xws li poly- paj rwb) yog qhov nyuaj rau kev sib cais thiab rov ua haujlwm zoo.
Txawm li cas los xij, innovation yog nrawm. Kev siv tshuaj siv tshuaj, uas tuaj yeem rhuav tshem cov ntaub zoo li polyester thiab paj rwb rau lawv cov qib molecular los tsim cov tshiab, siab - cov fibers zoo, yog qhov kev ua si - hloov cov tshuaj.
