Nyob rau hauv xyoo tas los no, qee qhov kev ua tiav tau ua tiav hauv cov khoom ntim ntsuab, uas tau nrov thiab siv hauv kev lag luam hauv tsev thiab thoob ntiaj teb. Green thiab environmentally friendly packaging cov ntaub ntawv xa mus rau cov ntaub ntawv uas ua raws li Life Cycle Assessment (LCA) nyob rau hauv cov txheej txheem ntawm kev tsim, siv thiab rov ua dua, uas yooj yim rau tib neeg siv thiab yuav tsis ua rau muaj kev puas tsuaj ntau dhau rau ib puag ncig, thiab tuaj yeem degraded. los yog rov siv dua los ntawm lawv tus kheej tom qab siv.
Tam sim no, peb feem ntau qhia cov ntaub ntawv eco-phooj ywg muab faib ua 4 hom: cov khoom siv ntawv, cov khoom siv roj ntsha, cov khoom siv degradable, cov khoom siv tau.
1. NtawvKhoom siv
Cov ntaub ntawv ntawv yog los ntawm cov khoom siv ntoo. Vim muaj qhov zoo ntawm kev degradation sai, yooj yim rov ua dua thiab siv ntau yam, cov ntaub ntawv ntawv tau dhau los ua cov khoom ntim ntsuab uas muaj ntau yam kev thov dav thiab siv sijhawm ntxov tshaj plaws.
Txawm li cas los xij, kev siv ntau dhau siv ntoo ntau heev. Tsis yog ntoo pulp yuav tsum nquag siv los ua ntawv, xws li reed, straw, bagasse, pob zeb thiab lwm yam, es tsis txhob ntoo, uas yuav ua rau irreversible kev puas tsuaj rau ib puag ncig.
Tom qab kev sivntawv ntim, nws yuav tsis ua rau muaj kev puas tsuaj rau lub ecology, thiab yuav degraded rau hauv cov as-ham. Yog li ntawd, niaj hnub no kev sib tw hnyav ntawm cov khoom ntim, cov ntawv ntim ntawv tseem muaj qhov chaw, nrog rau nws qhov tshwj xeeb zoo.
2. Cov khoom siv roj ntsha ntuj
Cov khoom ntim khoom siv roj ntsha feem ntau suav nrog cov khoom siv fiber ntau thiab cov khoom siv hmoov txhuv nplej siab, cov ntsiab lus ntawm nws yog siab dua 80%, nrog rau qhov zoo ntawm tsis muaj kuab paug, rov ua dua tshiab, ua haujlwm yooj yim thiab tseem muaj cov qauv zoo nkauj thiab siv tau. Tom qab siv, cov khoom noj uas raug tso tseg tuaj yeem hloov pauv thiab paub txog lub voj voog ecological.
Qee cov nroj tsuag yog cov khoom ntim ntuj, ntev npaum li kev ua me ntsis tuaj yeem ua lub ntuj tsw ntawm ntim, xws li nplooj, reeds, calabash, xyoob, thiab lwm yam.pob khoommuaj qhov zoo nkauj zoo nkauj thiab kab lis kev cai tsw, uas tuaj yeem ua rau tib neeg xav rov qab mus rau qhov xwm txheej thiab muaj kev xav zoo li qub ecology.
3. Cov khoom siv degradable
Cov ntaub ntawv degradable feem ntau yog ua los ntawm cov yas, ntxiv cov photosensitizer, hloov cov hmoov txhuv nplej siab, cov tshuaj lom neeg degradation thiab lwm yam khoom siv raw, kom txo tau qhov ruaj khov ntawm cov yas ib txwm siv, ua kom nws cov degradation ceev hauv ib puag ncig ntuj kom txo cov pa phem rau lub ntuj ib puag ncig. Raws li kev sib txawv degradation, lawv tuaj yeem muab faib ua cov ntaub ntawv biodegradable, cov ntaub ntawv photodegradable, thermal degradable cov ntaub ntawv thiab cov khoom siv degradable.
Tam sim no, cov ntaub ntawv tseem ceeb tshaj plaws degradable yog siv, xws li hmoov txhuv nplej siab, polylactic acid, PVA zaj duab xis; Lwm cov ntaub ntawv tshiab degradable, xws li cellulose, chitosan, protein thiab lwm yam ntaub ntawv degradable kuj muaj peev xwm loj hlob.
4. Cov khoom noj khoom haus
Cov khoom noj khoom haus yog cov khoom siv uas tuaj yeem noj ncaj qha lossis noj los ntawm tib neeg lub cev. Xws li: lipid, fiber, hmoov txhuv nplej siab, protein, thiab lwm yam ntxiv zog. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, cov ntaub ntawv no tau dhau los ua neeg paub tab thiab maj mam nce hauv xyoo tas los no, tab sis vim tias lawv yog cov khoom noj khoom haus-qib raw cov ntaub ntawv, thiab cov kev huv huv nruj yuav tsum tau ua hauv cov txheej txheem tsim khoom uas ua rau cov nqi siab.
Rau cov pa roj carbon tsawg ib puag ncig tiv thaiv ntim, kev txhim kho ntsuab tshiabntimcov ntaub ntawv yuav tsum yog indispensable, nyob rau tib lub sij hawm ntim tsim yuav tsum tau siv. Kev tiv thaiv ib puag ncig cov ntaub ntawv ntim hauv ntim tsim yuav dhau los ua ib qho ntawm cov ntawv thov tseem ceeb yav tom ntej.
Los ntawm kev txhim kho cov qauv tsim, tsim qauv tsim, ua kom cov khoom siv rov ua dua tshiab thiab siv cov khoom siv, peb yuav ua tiav cov txiaj ntsig ntawm ntau lub hom phiaj, txhawm rau txo kev siv cov khoom siv ntuj tsim.
