Yas tau teev tseg raws li ib qho ntawm cov kev tsim khoom loj tshaj plaws ntawm lub xyoo pua 20th. Yas zoo li rab ntaj ob sab. Thaum ua kom yooj yim rau peb, nws kuj coj lub nra hnyav rau ib puag ncig.
Txhawm rau tiv thaiv kev ua qias tuaj dawb, ntau lub teb chaws tau ua tiav ntau txoj cai. Thaum pib ntawm xyoo 2020, Tuam Tshoj tau tshaj tawm "Cov Kev Pom Zoo rau Kev Txhim Kho Ntxiv Ntxiv Kev Kho Mob Plastic Pollution". Thaum kawg ntawm xyoo 2020, kev lag luam catering thoob plaws Suav teb yuav txwv tsis pub siv cov yas pov tseg uas tsis muaj degradable.
Tam sim no, muaj peb yam tseem ceeb ntawm straws peb tau ntsib nyob rau hauv kev ua lag luam:PP cov kab,PLAcov quav, thiabdaim ntawv straws.
Los ntawm sab laug: ntawv straw,PLAstraw, PP straw
Raws li kev pom ntawm kev ua haujlwm degradation ntawm ntau yam straws, peb tau teeb tsa kev sib tw straw degradation.
Peb cog straws ntawm peb yam khoom sib txawv hauv cov av los simulate cov compost degradation ntawm straws ntawm ntau yam ntaub ntawv nyob rau hauv tej yam ntuj tso thiab saib dab tsi tshwm sim rau lawv tom qab 70 hnub:
ⅰ-PP hnab
Tom qab 70 hnub ntawm compost degradation, PP straws yeej tsis hloov pauv.
ⅱ-PLA quav
Tom qab 70 hnub ntawm compost degradation, PLA straw tsis hloov pauv loj.
ⅲ-daim ntawv straw
Tom qab 70 hnub ntawm compost degradation, qhov kawg ntawm daim ntawv straw tau pom tseeb rotted thiab degraded.
Cov txiaj ntsig kev ua si:Daim ntawv straws yeej qhov kev sib tw degradation.
Peb ua qhov sib piv yooj yim ntawm kev ua haujlwm ib puag ncig ntawm peb straws:
| Yam khoom | PP hnab | PLA quav | Daim ntawv straw |
| Cov khoom nyoos | Fossil zog | Bio zog | Bio zog |
| Rov qab los tsis tau | TSIS MUAJ | YOG | YOG |
| Ntuj degradation | TSIS MUAJ | YOG tab sis nyuaj heev | YOG thiab yooj yim |
