Kev rov ua dua tshiab yog qhov tseem ceeb thiab txawm tias cov kauj ruam me tshaj plaws tuaj yeem muaj txiaj ntsig zoo rau ib puag ncig. Kev nkag siab zoo dua ntawm cov txiaj ntsig ntawm kev rov ua dua tshiab tuaj yeem ua kom ntseeg tau tias nws dhau los ua ib feem tseem ceeb ntawm koj lub neej.
Recycling Reduces Landfill Waste
Lub Chaw Saib Xyuas Kev Tiv Thaiv Ib Cheeb Tsam Kev Txhim Kho Cov Khoom Siv Uas Tau Zoo: 2014 Fact Sheet (EPA fact sheet) hais tias 258 lab tons ntawm cov khib nyiab hauv nroog (MSW) tau tsim xyoo ntawd ib leeg. Los ntawm cov nyiaj ntawd, cov hauv qab no tshwm sim:
- 34.6% (89 lab tons) cov pov tseg tau rov qab los, ntawm 23 lab tons tau composted thiab 66 lab tons tau rov ua dua (pg. 4)
- 33 lab tons raug incinerated rau lub zog tiam (pg. 4)
- 136 lab tons (52%) xaus rau hauv qhov chaw pov tseg (pg. 4)
Qhov teeb meem ib puag ncig ntawm qhov chaw pov tseg yog qhov teeb meem nyuaj kho. Raws li ntau qhov pov tseg xaus hauv qhov chaw pov tseg, qhov teeb meem loj dua. Cov khoom uas tsis biodegradable los yog qeeb rau decompose, zoo li yas, tuaj yeem nyob hauv qhov chaw pov tseg rau ntau pua xyoo, feem ntau emission gases uas yuav ua rau muaj kev puas tsuaj rau ib puag ncig.
Daim ntawv qhia tseeb EPA (pg. 7, daim duab 8), qhia tias cov khib nyiab yog tsim los ntawm cov pov tseg hauv qab no, uas tuaj yeem rov ua dua tshiab:
- 21% ntawm cov zaub mov, qhov loj tshaj plaws ntawm cov pov tseg
- 14% ntawm daim ntawv thiab ntawv ntawv
- 10% ntawm roj hmab, tawv thiab textiles
- 18% ntawm cov yas
Nrog rau kev siv zog rov ua dua tshiab, cov khoom pov tseg rau qhov chaw pov tseg tuaj yeem txo qis ntxiv, yog li txo cov teeb meem thiab pab ib puag ncig.
Conserves Natural Resources
Kev tsim cov khoom lag luam yuav tsum muaj cov khoom siv nkauj xwb ntawm ob qho tib si tauj dua tshiab, thiab cov khoom siv hluav taws xob tsis txuas ntxiv lossis cov hlau ore. Lub National Institutes of He alth Environmental Management System tau tshaj tawm tias "94% ntawm cov khoom siv ntuj tsim los ntawm cov neeg Amelikas tsis tuaj yeem rov ua dua tshiab." Tus nqi ntawm cov peev txheej xws li fossil fuels thiab mineral ores uas tuaj yeem raug mined yog txwv. Ntawm lawv tam sim no tus nqi ntawm kev rho tawm thiab siv, lub ntiaj teb yuav kawg khiav tawm ntawm cov khoom muaj txiaj ntsig zoo li no. Yog li ntawd nws yog ib qho tseem ceeb kom txuag tau lawv rau yav tom ntej tiam. Thaum cov khoom tsim los ntawm cov khoom siv ntuj tsim xws li hlau lossis yas raug muab pov tseg rau hauv qhov chaw pov tseg, lawv poob rau tib neeg mus ib txhis.
Natural Resource Savings
Recycling kom ruaj khov siv cov peev txheej tsawg. Piv txwv li, LessIsMore.org teev cov nyiaj khaws tseg hauv qab no hauv cov peev txheej ntuj los ntawm kev rov ua dua ib tuj ntawm cov khoom siv:
- Recycled office paper: Txuag "17 tsob ntoo, 7,000 nkas loos dej, 463 nkas loos roj, thiab 3 cubic yards ntawm qhov chaw pov tseg"
- Recycled yas: Txuag mus txog 16.3 chim roj
- Recycled steel: Txuag 1.8 chim roj thiab 4 cubic yards hauv landfills
Cov peev txheej pov tseg nrog qhov muaj peev xwm rov ua dua tshiab
University of Southern Indiana muab lub tswv yim ntawm cov peev txheej pov tseg txhua xyoo hauv Asmeskas uas tuaj yeem rov qab tau yooj yim los ntawm kev rov ua dua tshiab.
- Cov txhuas uas tau muab pov tseg txhua xyoo yog txaus "kom rov tsim kho US kev lag luam dav hlau plaub zaug."
- Ib yam li ntawd, 1,200 phaus ntawm cov khib nyiab organic uas tsim los ntawm ib tus neeg Amelikas nruab nrab tuaj yeem ua tau composted.
Txuag hav zoov thiab lwm yam Habitats
Txoj hav zoov raug txiav los ua cov ntawv ua daim ntawv. Paper pulp suav txog 40% ntawm kev siv lub ntiaj teb cov ntoo raws li World Wide Fund For Nature. Nyob rau hauv lub tropics, deforestation rau daim ntawv rhuav tshem hav zoov ntau tshaj li mining los yog xibtes roj cog lus taw qhia txog lub Union ntawm kev txhawj xeeb Scientists. Dhau li ntawm kev txo cov ntoo thiab hom, cov tsiaj txhu muaj feem cuam tshuam raws li lawv cov chaw nyob raug puas tsuaj.
Ntau yam khoom muaj txiaj ntsig zoo li kub, tooj liab, pob zeb diamond thiab hlau ores pom nyob hauv thaj av hav zoov tshaj tawm Mongabay. Dhau li ntawm kev poob hav zoov, cov hav zoov tau degraded vim kev tsim kho ntawm txoj kev hla hav zoov, thiab tsim cov chaw nyob ib ntus. Ntxiv mus, cov neeg nyob hauv txo cov tsiaj txhu los ntawm kev yos hav zoov tsis raug cai.
Nyob rau xyoo 2007, NBC Xov Xwm tshaj tawm qhia tias kev siv zog rov ua dua tshiab hauv Suav teb ua rau muaj kev cuam tshuam loj heev rau kev rhuav tshem hav zoov thoob ntiaj teb, suav nrog Asmeskas thiab Europe. Tuam Tshoj tau xa cov ntawv pov tseg, nrog rau fiber ntau los ntawm nws tus kheej cov ntawv pov tseg thiab khaub ncaws, suav txog 60% ntawm nws cov khoom siv pulp. Txuag ntoo kuj tshwm sim nyob rau hauv Teb Chaws Asmeskas thaum daim ntawv rov siv dua. "Yog tias txhua tus neeg Asmeskas rov siv dua ib feem kaum ntawm lawv cov ntawv xov xwm, peb yuav txuag tau li 25,000,000 tsob ntoo hauv ib xyoos," sau tseg University of Southern Indiana.
Txo Kev Siv Zog
Lub zog loj yuav tsum tau ua rau kuv cov khoom siv raw, ua haujlwm thiab thauj mus thoob ntiaj teb. Ntau lub zog no tuaj yeem txuag tau yog tias tsim cov khoom lag luam xws li yas, hlau, lossis ntawv raug cais thiab rov ua dua tshiab, American Goescience Institute (AGI) piav qhia.
Tus nqi ntawm lub zog txuag nyob ntawm cov khoom uas lawv qhia meej. Yog li kev rov ua dua cov hlau txuag lub zog tshaj plaws. Piv txwv li, AGI hais tias:
- Tsuas yog 10-15% ntawm lub zog yog xav tau los siv iav dua piv rau kev tsim nws los ntawm kos, vim kev tsim iav yuav tsum muaj cua sov thiab lub zog ntau
- Ntawm tag nrho cov khoom tsim, txhuas ntau lawm yog lub zog siv zog tshaj plaws. Txawm li cas los xij rov ua dua txhuas tuaj yeem txuag tau 94% ntawm lub zog no.
- Zoo ib yam li rov ua dua lwm cov hlau xws li beryllium, txhuas, hlau thiab hlau, thiab cadmium txo qis kev siv zog los ntawm 80%, 75%, 72%, thiab 50%, feem, piv rau cov khoom tshiab.
Nyob rau xyoo 2014, 34.6% ntawm MSW uas tau rov siv dua tau txais lub zog txaus "kom muab hluav taws xob rau 30 lab lub tsev," raws li AGI. Lub EPA iwarm widget tuaj yeem siv los ntawm cov tib neeg kom kawm paub ntau npaum li cas lawv tuaj yeem txuag tau los ntawm kev rov ua dua cov khoom pov tseg hauv tsev sib txawv.
Txoj kev qias neeg
Recycling txo cov pa phem nyob rau hauv ob txoj kev: los ntawm kev txo cov khoom tshiab, littering thiab landfills, thiab tsis txhob incineration.
Kev tsim khoom
Muaj kev puas tsuaj ib puag ncig los ntawm kev khawb cov ntaub ntawv raw lossis txiav ntoo. Qhov no yog ua raws li cov txheej txheem tsim khoom. Ntau yam kab mob tshwj xeeb xws li radionuclides, plua plav, hlau, brine thiab lwm yam. leach tawm thiab ua paug rau thaj av thiab dej nyob ib puag ncig thaum mining, raws li Massachusetts Institute of Technology. Cov chaw ntawm huab cua, av thiab dej paug tuaj yeem zam tau los ntawm kev rov ua dua tshiab.
Piv txwv:
- Recycling yas fwj tuaj yeem txuag tau txog 60% ntawm lub zog siv los ua ntau dua.
- Steel los ntawm cov khoom siv dua tshiab txo cov pa tawm los ntawm 85% thiab txiav 76% ntawm dej paug.
Kev Tswj Xyuas Tsis Muaj Zog
Vim yog decomposition thiab cov khoom ntawm cov khib nyiab sib txawv, muaj cov pa roj thiab paug tawm thaum cov thoob khib nyiab pov tseg tsis khaws cia li khib nyiab lossis txawm nyob hauv qhov chaw pov tseg. Cov no tuaj yeem khiav mus rau hauv ib puag ncig thiab ua paug huab cua, cov av ib puag ncig, lossis cov dej ua rau muaj teeb meem kev noj qab haus huv rau tib neeg, thiab kev puas tsuaj rau cov nroj tsuag raws li kev tshuaj xyuas kev tshawb fawb los ntawm 1997 hauv Phau Ntawv Xov Xwm ntawm Kev Tswj Xyuas Ib puag ncig, thiab cov teeb meem no tseem muaj teeb meem niaj hnub no.
Cov pa phem khiav mus rau hauv dej thiab nkag mus rau hauv av. Dej nyab yog tshwm sim los ntawm cov khib nyiab txhaws, thiab cov huab cua tuaj yeem raug tshuaj lom los ntawm cov pa phem los ntawm cov thoob khib nyiab raws li tsab ntawv ceeb toom 2016 Los Angeles Times.
Avoid Incineration
The Times tsab ntawv ceeb toom hais tias incineration ntawm cov pov tseg tsis yog ib qho kev daws teeb meem. Nws pollutes huab cua thiab dej. Dhau li ntawm ib puag ncig, tib neeg kev noj qab haus huv thiab kev nyab xeeb tseem raug cuam tshuam, ua rau muaj kev cuam tshuam nyiaj txiag rau tib neeg thiab tib neeg, vim tias kev tua hluav taws ua rau muaj kev pheej hmoo kis mob ua pa lossis raws plab los ntawm rau lub sijhawm. Raws li EPA cov ntaub ntawv tseeb, 12% ntawm MWS raug hlawv hauv 2014 hauv Asmeskas
Tsuas Ntiaj Teb Warming
Recycling pab kom txo tau qhov kev hloov pauv huab cua. EPA piav qhia tias 42% ntawm Teb Chaws Asmeskas cov pa hluav taws xob hauv tsev cog khoom (GHG) emissions tshwm sim vim kev tsim khoom, kev ua, kev thauj mus los, thiab pov tseg cov khoom xws li zaub mov. Cov txheej txheem no yog siv los ntawm kev siv fossil fuels, yog ib qhov chaw loj ntawm emissions hauv U. S. Nyob rau xyoo 2014, MSW uas tau siv dua lossis ua kom sib xyaw txo GHG emissions los ntawm 181 lab metric tons, qhia txog EPA cov ntawv tseeb.
Kev txo qis hauv ib theem ntawm cov khoom lag luam lub neej yog li cas kev rov ua dua tshiab pab rau ib puag ncig, suav nrog kev tawm tsam thoob ntiaj teb.
Kev cuam tshuam ib puag ncig zoo tshaj li tus nqi peev txheej
Tus nqi siab koom nrog kev rov ua dua tshiab ua rau qee tus neeg tsis ntseeg txog cov txiaj ntsig cuam tshuam. Txawm li cas los xij raws li Scientific American piav qhia, qhov no muaj ntau yam teeb meem cuam tshuam nrog kev sib cais tsis zoo, dua li kev rov ua dua nws tus kheej. Qhov teeb meem no tau tshwm sim los ntawm kev qhia txog cov khoom ntim loj uas cov neeg siv pov tseg cov khib nyiab sib txawv ua ke, ua rau cov nqi ntxiv hauv kev txheeb lossis txawm tias cov khib nyiab pov tseg.
Txhob Cia Siab Rau Txhua Tus
Nyob ib ncig ntawm 1.3 billion tons ntawm pov tseg raug tsim tawm thoob ntiaj teb txhua xyoo taw qhia Los Angeles Times tsab ntawv ceeb toom. Recycling tsuas yog ib qho ntawm ntau txoj hauv kev los pab ib puag ncig los ntawm kev txo lub nra ntawm cov pov tseg ntawm nws. Txhua kauj ruam suav thiab yog ib qho ntxiv rau kev pab thiab txhawb ib puag ncig. Txhua tus neeg txoj kev koom tes yog qhov tsim nyog, txij li menyuam yaus mus rau cov neeg laus, los pab tsim kom muaj ib puag ncig zoo rau ntau tiam neeg tom ntej.
