Tshaj tag nrho, nws muaj tseeb tias cov ntawv daig ntawv yog qhov zoo dua rau ib puag ncig zoo dua lawv cov ntawv yas. Txawm li cas los xij, cov ntawv daig ntawv tseem tuaj nrog lawv tus kheej cov teeb meem ib puag ncig tsis zoo.

Rau ib qho, ntau tus neeg ntseeg tias cov ntawv lag luam yog cov khoom siv tsawg siv los tsim dua li cov hlua yas. Tom qab tag nrho, daim ntawv yog biodegradable thiab los ntawm cov ntoo, uas yog cov khoom siv dua tshiab.

Hmoov tsis zoo, uas yog cias tsis yog cov ntaub ntawv! Qhov tseeb, cov ntawv lag luam nyob rau hauv dav dav xav tau ntau lub zog thiab cov khoom siv los tsim dua li cov khoom siv yas (Qhov Chaw). Qhov no yuav zoo li qhov tsis pom kev, tab sis nws yog qhov tseeb tiag!

Piv txwv li, kev tsim cov ntawv ntim khoom siv siv plaub zaug los ua lub zog ntau dua li cov khoom yas. Feem ntau, cov tsev cog khoom roj tsev ntau dua qhov tawm thaum lub sijhawm cov ntawv siv dua li lawv cov ntawv yas.

Qhov no tshwm sim vim hais tias cov pob txha roj ua kom muaj zog lub tshuab ua khoom siv thiab khoom siv hauv kev tsim cov khoom siv ntawm cov yas thiab ntawv qhwv. Tab sis txij li cov ntawv lag luam yog cov siv hluav taws xob ntau dua los ua khoom, cov khoom siv los ntawm cov ntawv thom khwm yeej siv ntau cov peev txheej (thiab tawm cov khoom siv tsev cog khoom ntau dua) ntau dua li cov yas tso tawm ntau!

Ua rau cov teeb meem tsis zoo, cov ntaub qhwv ntawv kuj tseem muaj peev xwm ua kom raug mob tsiaj yog tias lawv raug ntas mus rau hauv dej hiav txwv, zoo ib yam li cov hlua yas. Nrog uas tau hais tias, txawm li cas los xij, cov ntawv xaim ntawv feem ntau tseem yuav tsis muaj kev phom sij ntau dua li cov yas, vim tias nws yog qhov siv tau tsawg dua, thiab yuav tsum siv biodegrade.

Vim li cas kuv thiaj hais, "yas straws yuav tsum biodegrade"? Zoo, kuv yuav tham txog qhov ntxiv mus.
