Ib txoj kev tshawb fawb tshiab qhia tau hais tias cov ntawv txhuas txhuas tuaj yeem ua lub luag haujlwm tseem ceeb hauv kev txo cov khoom noj khoom haus. Cov kws tshawb fawb tau pom tias siv cov ntawv txhuas los qhwv thiab khaws cov zaub mov tuaj yeem pab ua kom nws tshiab rau ntev, yog li txo cov khoom noj uas muab pov tseg.
Txoj kev tshawb no, ua los ntawm American Chemical Society, tau saib qhov ua tau zoo ntawm ntau txoj hauv kev khaws cov zaub mov hauv kev khaws cia qhov tshiab ntawm ntau hom zaub mov. Cov kws tshawb nrhiav pom tias siv cov ntawv txhuas los qhwv cov khoom noj xws li qhaub cij, txiv hmab txiv ntoo, thiab zaub pab tswj lawv cov tshiab thiab tiv thaiv kev lwj.
Dr. John Smith, tus thawj coj ntawm txoj kev tshawb fawb tau hais tias "Aluminium foil ua rau lub teeb, noo noo, thiab huab cua, uas yog qhov ua rau cov khoom noj tsis zoo," said Dr. "Los ntawm kev siv cov ntawv txhuas los qhwv thiab khaws cov zaub mov, cov neeg siv khoom tuaj yeem txo qis cov khoom noj khoom haus hauv lawv tsev neeg."
Raws li United Nations Food and Agriculture Organization, nyob ib ncig ntawm ib feem peb ntawm tag nrho cov khoom noj uas tsim nyob rau hauv lub ntiaj teb no yog ploj los yog nkim. Qhov no suav nrog kwv yees li 1.3 billion tonnes ntawm zaub mov txhua xyoo. Cov zaub mov pov tseg muaj qhov cuam tshuam loj rau kev lag luam, kev sib raug zoo, thiab ib puag ncig, ua rau muaj cov pa hluav taws xob hauv tsev cog khoom, deforestation, thiab dej khib nyiab.
Kev siv cov ntawv txhuas hauv cov khoom noj khoom haus tuaj yeem muaj lwm yam txiaj ntsig. Nws yog ib qho khoom siv hnyav thiab tus nqi tsim nyog uas muaj dav thiab siv tau yooj yim. Aluminium ntawv ci kuj tseem tuaj yeem siv dua, ua rau nws xaiv ib puag ncig zoo.
"Los ntawm kev siv cov ntawv txhuas txhuas hauv cov khoom noj khoom haus, peb tuaj yeem txo qis cov khoom noj khoom haus xwb tab sis kuj txhawb kev ruaj ntseg," said Dr. Smith. "Nws yog ib kauj ruam me me uas tuaj yeem cuam tshuam loj."
Qhov kev tshawb pom ntawm txoj kev tshawb fawb tau txais tos los ntawm ib puag ncig cov pab pawg thiab cov neeg tawm tsam cov khoom noj pov tseg, uas tau hu kom muaj kev paub ntau dua ntawm qhov teeb meem ntawm cov khoom noj khib nyiab thiab lub luag haujlwm uas yooj yim ntsuas xws li siv cov ntawv txhuas tuaj yeem ua rau nws.
Hauv kev xaus, kev siv aluminium ntawv ci los qhwv thiab khaws cov zaub mov yog ib txoj hauv kev yooj yim thiab siv tau los txo cov khoom noj khoom haus thiab txhawb kev ruaj khov. Nrog rau cov khoom pov tseg tau dhau los ua qhov teeb meem hnyav zuj zus, nws yog ib qho tseem ceeb uas cov neeg siv khoom yuav tsum tau ua cov kauj ruam los txo lawv cov khoom pov tseg thiab txhawb kom lwm tus ua ib yam.
