Kev ua haujlwm ib puag ncig ntawm cov thawv ntawv khoom plig tuaj yeem txheeb xyuas los ntawm cov hauv qab no:
1. Cov ntaub ntawv: Cov thawv ntawv khoom plig feem ntau siv cov khoom siv txuas ntxiv dua tshiab xws li cov duab los qhia thiab ntawv, muab kev ua haujlwm zoo ib puag ncig piv rau cov khoom tsis yog- cov khoom siv dua tshiab xws li yas thiab hlau. Xaiv cov ntaub ntawv siv rov ua dua tshiab thiab biodegradable yuav txo tau cov peev txheej siv thiab kev cuam tshuam ib puag ncig.
2. Cov txheej txheem tsim khoom: Cov txheej txheem tsim khoom ntawm cov thawv ntawv khoom plig yog qhov yooj yim, feem ntau yuav tsum tau siv hluav taws xob tsawg thiab cov khoom siv tshuaj lom neeg, ua rau muaj kuab paug tsawg. Tsis tas li ntawd, kev siv thev naus laus zis ntau zuj zus hauv cov ntawv ntim khoom plig pub rau kev tswj hwm kev siv hluav taws xob zoo thiab tsim khoom pov tseg thaum lub sijhawm tsim khoom.
3. Recyclability: Daim ntawv lub thawv khoom plig yog qhov yooj yim rau rov ua dua. Cov txheej txheem rov ua dua txo qhov kev thov rau cov ntawv tsim khoom, txuag cov peev txheej. Cov txheej txheem rov ua dua tshiab kuj tseem yooj yim thiab yooj yim rau cov koom haum ib puag ncig thiab tib neeg los siv.
4. Biodegradability: Feem ntau lub thawv khoom plig siv cov khoom siv fiber ntau. Los ntawm natural degradation, lawv tsis tsim tshuaj lom los yog teeb meem thiab tsis ua phem rau av los yog dej. Xaiv cov ntaub ntawv tsis muaj tshuaj ntxiv tuaj yeem txhim kho biodegradability ntawm cov thawv khoom plig.
