Nyob rau xyoo tas los no, muaj kev txhawj xeeb thoob ntiaj teb txog kev ruaj khov ntawm ib puag ncig. Qhov kev paub txog kev loj hlob no tau ua rau muaj kev tsim kho thiab kev siv ntau yam kev daws teeb meem uas zoo rau ib puag ncig, suav nrog kev sivcov ntawv xa ntawv uas lwj tauhauv kev ntim khoom thiab kev xa khoom.
Cov ntawv xa ntawv Poly, tseem hu ua cov hnab polyethylene, yog siv dav rau kev ntim khoom thiab xa khoom vim lawv lub zog ruaj khov thiab kev siv nyiaj tsim nyog. Txawm li cas los xij, lawv qhov xwm txheej tsis lwj tau tsa kev txhawj xeeb txog lawv qhov cuam tshuam mus sij hawm ntev rau ib puag ncig. Txhawm rau daws cov kev txhawj xeeb no, cov tuam txhab tau nqis peev rau hauv kev tshawb fawb thiab kev txhim kho ntawmcov ntawv xa ntawv uas lwj taunyob rau hauv Tebchaws Europe thiab Amelikas.
Cov ntawv xa ntawv uas lwj tautau tsim los kom yooj yim tawg thiab muaj kev nyab xeeb thaum lawv raug pov tseg, txo qhov kev puas tsuaj rau ib puag ncig. Cov ntawv xa ntawv no feem ntau yog ua los ntawm kev sib xyaw ua ke ntawm cov polyethylene ib txwm muaj thiab ntau yam khoom siv biodegradable. Cov khoom siv ntxiv pab txhawb rau cov txheej txheem degradation, cia cov ntawv xa ntawv lwj raws sijhawm.
Ib qho ntawm cov tsav tsheb tseem ceeb ntawm kev loj hlob ntawmcov ntawv xa ntawv uas lwj taunyob rau hauv Tebchaws Europe thiab Amelikas yog kev nruj ntawm cov cai ib puag ncig. Tsoomfwv thiab cov koom haum tswj hwm tab tom muab kev tsom mus rau kev txo cov khib nyiab yas thiab txhawb kom siv cov kev xaiv ntim khoom ruaj khov. Qhov no tau yuam kom cov chaw tsim khoom tshawb nrhiav thiab nqis peev rau cov kev xaiv uas zoo rau ib puag ncig xws licov ntawv xa ntawv uas lwj tau.
Tsis tas li ntawd xwb, kev xav tau ntawm cov neeg siv khoom rau cov khoom lag luam uas ruaj khov tau yog ib qho tseem ceeb hauv kev txhim kho thiab kev sivcov ntawv xa ntawv uas lwj tauThaum tib neeg paub ntau ntxiv txog qhov cuam tshuam rau ib puag ncig ntawm lawv cov kev ua, lawv tab tom nrhiav cov khoom uas phim nrog lawv cov txiaj ntsig. Qhov kev hloov pauv ntawm tus cwj pwm ntawm cov neeg siv khoom no tau ua rau cov lag luam siv cov kev daws teeb meem ntim khoom ruaj khov, xws licov ntawv xa ntawv uas lwj tau, kom sib tw tau zoo thiab ua tau raws li cov neeg siv khoom xav tau.
Tsis tas li ntawd xwb, kev nce qib hauv thev naus laus zis tau ua lub luag haujlwm tseem ceeb hauv kev txhim kho qhov zoo thiab kev ua tau zoo ntawmcov ntawv xa ntawv uas lwj tauCov chaw tsim khoom tau nqis peev rau kev tshawb fawb thiab kev txhim kho kom txhim kho lub zog, kev ruaj khov, thiab kev ua haujlwm tag nrho ntawm cov ntawv xa ntawv no, ua rau lawv yog lwm txoj hauv kev zoo rau cov kev xaiv uas tsis lwj. Qhov no tau tso cai rau cov lag luam koom ua kecov ntawv xa ntawv uas lwj taurau hauv lawv cov txheej txheem ntim khoom thiab xa khoom yam tsis muaj kev cuam tshuam rau kev ua haujlwm zoo lossis kev ua haujlwm zoo.
Kev koom tes thiab kev sib pauv kev paub ntawm cov neeg ua lag luam, cov tsev kawm ntawv qib siab, thiab cov tsev kawm tshawb fawb kuj tau txhawb nqa txoj kev loj hlob ntawmcov ntawv xa ntawv uas lwj tauLos ntawm kev sib qhia kev txawj ntse thiab cov peev txheej, cov tuam txhab tau ua kom muaj kev tsim kho tshiab thiab kev siv cov kev daws teeb meem ntim khoom ruaj khov no. Kev koom tes no tau ua rau muaj cov thev naus laus zis tshiab thiab cov txheej txheem tsim khoom uas zoo rau ib puag ncig thiab muaj txiaj ntsig zoo dua.
Hauv kev xaus, qhov kev loj hlob ntawmcov ntawv xa ntawv uas lwj taunyob rau hauv Tebchaws Europe thiab Amelikas yog ib qho kev teb rau qhov kev paub txog kev ruaj khov ntawm ib puag ncig thiab qhov xav tau kev txo cov khib nyiab yas. Kev tshuaj xyuas kev cai lij choj ntau ntxiv thiab kev thov ntawm cov neeg siv khoom rau cov kev xaiv uas zoo rau ib puag ncig tau tsav cov lag luam kom nqis peev rau hauv kev tshawb fawb thiab kev txhim kho ntawmcov ntawv xa ntawv uas lwj tauKev nce qib ntawm thev naus laus zis thiab kev koom tes ntawm cov neeg ua lag luam hauv kev lag luam tau pab txhawb rau kev nce qib hauv daim teb no. Thaum ntau lub tuam txhab hloov mus rau cov kev daws teeb meem ntim khoom ruaj khov, nws xav tias cov ntawv xa ntawv poly uas lwj tau yuav txuas ntxiv mus thiab dhau los ua tus qauv hauv kev lag luam ntim khoom thiab xa khoom, pab txhawb rau yav tom ntej ntsuab dua thiab ruaj khov dua.
