Biodegradable hnab yas tseem tuaj yeem nqa mus yuav khoom peb xyoos tom qab tso rau hauv ib puag ncig ntuj.
Tsib cov khoom siv hnab yas pom hauv UK cov khw tau sim saib seb yuav muaj dab tsi tshwm sim rau lawv hauv ib puag ncig uas lawv tuaj yeem tshwm sim yog tias muaj khib nyiab.
Lawv txhua tus tau tawg mus rau hauv cov khoom tawg tom qab raug cua rau cuaj lub hlis.
Tab sis tom qab ntau tshaj peb xyoos nyob rau hauv av los yog hiav txwv, peb ntawm cov ntaub ntawv, nrog rau biodegradable hnab, tseem tsis tau.
Compostable hnab tau pom tias yog me ntsis friendlier rau ib puag ncig - tsawg kawg hauv hiav txwv.
Tom qab peb lub hlis hauv qhov chaw marine lawv tau ploj mus, tab sis tseem tuaj yeem pom hauv av 27 lub hlis tom qab.
Cov kws tshawb fawb ntawm University of Plymouth tau sim cov khoom sib txawv ntawm ib ntus kom pom tias lawv tau tawg li cas.
Lawv hais tias kev tshawb fawb tau nug cov lus nug txog cov khoom lag luam biodegradable tau ua lag luam rau cov neeg yuav khoom raws li kev hloov pauv rau cov yas uas tsis yog siv dua tshiab.
"Rau lub hnab biodegradable kom muaj peev xwm ua tau qhov ntawd yog qhov xav tsis thoob tshaj," hais tias Imogen Napper, uas yog tus coj txoj kev tshawb fawb.
"Thaum koj pom ib yam dab tsi uas sau rau hauv txoj kev ntawd kuv xav tias koj cia li xav tias nws yuav degrade sai dua li cov hnab ntim khoom.
"Tab sis tom qab peb xyoos tsawg kawg, peb cov kev tshawb fawb qhia tias tej zaum yuav tsis yog li ntawd."
Biodegradable v compostable
Yog tias ib yam dab tsi biodegradable nws tuaj yeem tawg los ntawm cov kab mob muaj sia xws li cov kab mob thiab cov fungi.
Xav txog ib daig txiv hmab txiv ntoo sab laug ntawm cov nyom - muab sijhawm rau nws thiab nws yuav tshwm sim kom ploj tag.Qhov tseeb tiag nws tsuas yog "digested" los ntawm cov kab mob.
Nws tshwm sim rau cov khoom ntuj yam tsis muaj kev cuam tshuam rau tib neeg tau muab cov xwm txheej zoo - xws li kub thiab muaj oxygen.
Composting yog tib yam, tab sis nws yog tswj los ntawm tib neeg los ua kom cov txheej txheem sai.
Co-op'shnab yas compostableyog tsim rau cov khoom pov tseg, thiab yuav tsum tau muab faib ua compostable lawv yuav tsum tau tawg tsis pub dhau 12 lub lis piam raws li tej yam kev mob.
Cov kws tshawb fawb ntawm Plymouth kuj tau nug txog tias cov khoom siv biodegradable zoo li cas yog qhov kev daws teeb meem ntev rau cov teeb meem ntawm cov yas siv ib zaug.
"Qhov kev tshawb fawb no tsa ntau cov lus nug txog dab tsi pej xeem yuav xav tau thaum lawv pom ib yam dab tsi sau tias biodegradable.
"Peb ua qauv qhia ntawm no tias cov khoom siv kuaj tsis muaj qhov sib xws, txhim khu kev qha thiab muaj txiaj ntsig zoo hauv cov ntsiab lus ntawm cov khib nyiab marine.
"Nws txhawj xeeb rau kuv tias cov ntaub ntawv tshiab no tseem muaj teeb meem hauv kev rov ua dua tshiab," said Professor Richard Thompson, tus thawj coj ntawm International Marine Litter Research.
Hauv txoj kev tshawb no, cov kws tshawb fawb tau hais txog 2013 European Commission tsab ntawv ceeb toom uas qhia txog 100 billion lub hnab yas tau raug xa tawm txhua xyoo.
Ntau lub tseemfwv, suav nrog UK, txij li tau qhia txog kev ntsuas xws li cov nqi los txo tus lej siv.
