Hauv kev tshawb nrhiav kom muaj txiaj ntsig zoo thiab muaj txiaj ntsig zoo rau cov khoom siv yas, cov khoom siv xyoob fiber ntau tau tshwm sim los ua ib qho kev cog lus. Keeb kwm los ntawm qhov xwm txheej, xyoob fiber ntau yog cov khoom siv degradable sai heev uas tau siv los hloov cov yas. Qhov kev hloov pauv no tsis tsuas yog ua tau raws li cov pej xeem cov kev xav tau rau cov khoom lag luam zoo xwb tab sis kuj ua raws li lub ntiaj teb kev thawb rau cov kev coj ua uas tsis muaj cov pa roj carbon tsawg thiab ib puag ncig zoo.
Cov khoom xyoob yog muab los ntawm cov xyoob ntoo txuas ntxiv, ua rau lawv hloov tau zoo rau cov yas. Cov khoom no decompose sai sai, rov qab mus rau qhov xwm txheej thiab txo qis ib puag ncig lub nra ntawm kev pov tseg. Qhov biodegradability no txhawb nqa lub voj voog tsim txiaj ntawm kev siv cov peev txheej, pab txhawb rau yav tom ntej.
Lub teb chaws thiab cov koom haum thoob ntiaj teb tau lees paub lub peev xwm ntawm cov khoom xyoob thiab tau koom nrog "txo yas" phiaj xwm, txhua tus pab txhawb lawv cov kev daws teeb meem ntsuab.
1. Suav teb
Tuam Tshoj tau coj lub luag haujlwm tseem ceeb hauv qhov kev txav no. Tsoom fwv Suav, koom tes nrog International Bamboo thiab Rattan Organization, tau pib lub "Bamboo es tsis txhob yas" teg num. Qhov kev pib no tsom mus rau kev hloov cov khoom yas nrog txhua cov khoom xyoob thiab cov khoom siv xyoob sib xyaw. Cov txiaj ntsig tau zoo heev: piv rau xyoo 2022, kev nthuav dav ntxiv ntawm cov khoom tseem ceeb nyob rau hauv qhov kev pib no tau nce ntau dua 20%, thiab kev siv dav dav ntawm xyoob tau nce 20 feem pua.
2. Teb Chaws Asmeskas
Lub tebchaws United States tseem tau nqis tes ua tseem ceeb hauv kev txo cov pov tseg yas. Raws li US Environmental Protection Agency, cov khib nyiab yas hauv lub tebchaws tau nce los ntawm 0.4% ntawm tag nrho cov khib nyiab hauv nroog hauv xyoo 1960 txog 12.2% hauv 2018. Hauv kev teb, cov tuam txhab xws li Alaska Airlines thiab American Airlines tau ua cov kauj ruam ua haujlwm. Alaska Airlines tshaj tawm nyob rau lub Tsib Hlis 2018 tias nws yuav tshem tawm cov yas straws thiab txiv hmab txiv ntoo diav rawg, thaum American Airlines hloov cov khoom yas nrog xyoob nplawm nplaum rau txhua lub davhlau pib thaum lub Kaum Ib Hlis 2018. Cov kev hloov no tau kwv yees kom txo cov pov tseg yas ntau dua 71,000 phaus (kwv yees li 32,000. kg) txhua xyoo.
Hauv kev xaus, cov khoom xyoob tau ua lub luag haujlwm tseem ceeb hauv lub ntiaj teb "txo yas" txav. Lawv qhov degradability sai thiab rov ua dua tshiab ua rau lawv yog qhov zoo tshaj plaws rau cov khoom siv yas, pab tsim kom muaj lub ntiaj teb zoo dua qub thiab ib puag ncig zoo.
