III. Environmental Standards thiab ntawv pov thawj
A. Muaj feem cuam tshuam ib puag ncig cov qauv rau ntsuab degradable ntawv khob
Cov txheej txheem ib puag ncig cuam tshuam rau cov ntawv khob ntsuab degradable yog hais txog cov kev xav tau thiab cov ntsiab lus qhia uas yuav tsum tau ua thaum lub sijhawm tsim khoom, siv, thiab kev kho mob. Cov qauv no tsom xyuas kom muaj kev ua tau zoo ntawm ib puag ncig thiab kev ruaj ntseg ntawm ntsuab degradable ntawv khob. Cov hauv qab no yog qee cov qauv ib puag ncig rau ntsuab degradable ntawv khob.
1. Qhov chaw ntawm pulp. Ntsuab degradabledaim ntawv khobyuav tsum siv cov ntaub qhwv los ntawm cov hav zoov uas muaj kev tswj hwm ruaj khov lossis tau txais FSC (Forest Stewardship Council) ntawv pov thawj. Qhov no tuaj yeem ua kom ntseeg tau tias kev tsim cov khob ntawv tsis ua rau kev siv ntau dhau los yog kev puas tsuaj rau cov peev txheej hav zoov.
2. Tshuaj lom neeg txwv. Green degradable ntawv khob yuav tsum ua raws li cov kev txwv tshuaj lom neeg. Kev txwv tsis pub siv cov khoom tsis zoo xws li cov hlau hnyav, dyes, reactive oxidants, thiab bisphenol A. Qhov no tuaj yeem txo cov kev phom sij rau ib puag ncig thiab tib neeg kev noj qab haus huv.
3. Degradability. Ntsuab degradable ntawv khob yuav tsum muaj zoo degradability. Cov khob ntawv feem ntau yuav tsum tau ua kom tiav degradation nyob rau hauv ib lub sij hawm. Nws yog qhov zoo tshaj plaws rau cov khob ntawv kom muaj peev xwm ua kom pom lawv cov degradability los ntawm cov ntawv pov thawj cuam tshuam.
4. Carbon hneev taw thiab siv zog. Cov txheej txheem tsim cov khob ntawv ntsuab degradable yuav tsum txo qis carbon emissions kom ntau li ntau tau. Thiab lub zog uas lawv siv yuav tsum yog los ntawm cov khoom siv txuas ntxiv lossis cov pa roj carbon tsawg.
Lub koom haum International rau Standardization (ISO) muab kev taw qhia thiab kev qhia tshwj xeeb rau kev tsim khoom thiab siv cov khob ntawv ntsuab degradable. Cov no suav nrog cov kev xav tau rau cov khoom siv hauv kev tsim khoom, lub sijhawm degradation, thiab cov nyhuv degradation. Nyob rau tib lub sijhawm, lub teb chaws lossis cheeb tsam kuj tau tsim cov qauv thiab kev tswj hwm ib puag ncig. Cov no suav nrog kev ua haujlwm degradation thiab ib puag ncig tus phooj ywg ntawm cov khob ntawv.
B. Certification Authority thiab Certification Process
Lub koom haum World Paper Cup yog ib lub koom haum tso cai hauv kev lag luam khob ntawv. Lub koom haum no tuaj yeem lees paub cov khoom ntim ntawv. Nws cov txheej txheem ntawv pov thawj suav nrog kev sim cov khoom siv, kev ntsuam xyuas ecological, thiab kuaj degradability.
Green Product Certification Institutions tseem tuaj yeem muab cov kev pabcuam ntawv pov thawj rau ntsuab degradable ntawv khob. Nws ntsuas thiab lees paub cov khoom zoo, ib puag ncig tus phooj ywg, thiab lwm yam.
C. Qhov tseem ceeb thiab tus nqi ntawm daim ntawv pov thawj
Ua ntej, tau txais ntawv pov thawj tuaj yeem txhim kho lub tuam txhab cov duab thiab kev ntseeg siab. Thiab cov neeg siv khoom yuav ntseeg tau ntawv pov thawj ntsuab biodegradable ntawv khob ntau dua. Qhov no muaj txiaj ntsig zoo rau kev tshaj tawm kev lag luam thiab kev muag khoom ntawm cov khoom. Qhov thib ob, ntawv pov thawj tuaj yeem coj kev sib tw zoo rau cov khoom. Qhov no tuaj yeem ua rau cov lag luam muaj kev sib tw hauv kev ua lag luam. Thiab qhov no yuav pab lawv nthuav lawv txoj kev lag luam ntxiv. Tsis tas li ntawd, daim ntawv pov thawj xav kom cov tuam txhab lag luam txuas ntxiv txhim kho thiab tsim kho tshiab. Qhov no tuaj yeem txhawb cov tuam txhab kom txhim kho cov khoom zoo thiab kev ua haujlwm ib puag ncig.
