Singapore: Koj yuav xav tias hloov ntawm ib-kev siv cov plastics yog qhov zoo rau ib puag ncig, muaj "tsis muaj txiaj ntsig", cov kws tshaj lij hais tias.
Lawv feem ntau xaus rau tib qho chaw - tus kws qhia ntawv, hais tias muaj ib tug xibhwb uas tau hais txog cov neeg saib xyuas cov tshuaj thiab cov neeg caij tsheb kauj ruam ntawm National University of Singapore (NUS).
Biodegradable Yas khib nyiab ua qhov sib txawv rau ib puag ncig tsuas yog thaum lawv faus rau hauv av pov tseg, nws ntxiv.
"Hauv cov xwm txheej no, cov hnab yas tuaj yeem txwv nrawm dua li piv rau cov hnab yas li niaj zaus yas thiab yuav tsis cuam tshuam rau ib puag ncig ntau. Zuag qhia tag nrho rau Singapore, nws kuj tseem kim kim rau incinerate biodegradable plastics, "hais nrog profectics," hais tias assf tong. Nws piav qhia tias qhov no yog vim qee qhov kev xaiv biodegradable siv cov peev txheej ntau los tsim, uas ua rau lawv kim dua.
Lub tswv yim squares nrog dab tsi Dr Amy Khor, cov neeg kawm txog lub sijhawm tau hais hauv lub Yim Hli thiab cov chaw lis dej num hauv lub xeev (Nea) pom tias muaj kev hloov pauv Cov yas nrog lwm hom khoom ntim ntim ib leeg yog "tsis tas yuav zoo dua rau ib puag ncig".
"Hauv Singapore, khib nyiab yog incinerated thiab tsis laug rau hauv av pov tseg. Qhov no txhais tau tias cov peev txheej uas xav tau ntawm cov hnab ntim oxo-degradable zoo ib yam li ntawd ntawm cov yas yas, thiab lawv kuj muaj ib qho kev cuam tshuam zoo sib xws thaum incinerated.
"Ntxiv rau, oxo-degradable hnab yuav cuam tshuam nrog cov txheej txheem rov ua dua tshiab thaum sib xyaw nrog cov pa muaj txiaj ntsig," kev kawm no.
Oxo-degradable plastics sai li sai thiab me me, hu ua microplastics, tab sis tsis txhob tawg ntawm qib molecular lossis polymer theem zoo li biodegradable thiab compstable plastics.
Lub resulting microplastics yog sab laug hauv qhov chaw ib puag ncig mus txog thaum lawv kawg tag nrho.
Heafe European Union (EU) muaj qhov tseeb tau txiav txim siab nyob rau hauv Lub Peb Hlis mus rau cov khoom txwv txiav tawm ntawm oxo-degradable yas raws li kev txiav txim siab ntawm kev siv cov yas.
Hauv kev txiav txim siab, EU hais oxo-degradable yas "tsis yog tsim kom haum rau microplastic vollued nyob rau hauv ib puag ncig".
