Roasters tau siv ntau cov ntaub ntawv zoo ib puag ncig rau lawv lub khob thiab hnab raws li kev txhawj xeeb txog qhov cuam tshuam ntawm kas fes ntim rau ib puag ncig loj hlob.
Qhov no yog qhov tseem ceeb rau kev muaj sia nyob ntawm lub ntiaj teb nrog rau kev ua tiav ntev ntawm kev lag luam roasting.
Cov khib nyiab hauv nroog (MSW) yog qhov thib peb loj tshaj plaws ntawm tib neeg cov methane emissions hauv Tebchaws Meskas, uas muaj txiaj ntsig zoo rau lub ntiaj teb sov sov, raws li kev kwv yees tam sim no.
Raws li qhov tshwm sim, ntau tus neeg tau hloov pauv los ntawm kev ntim khoom los ntawm cov ntaub ntawv nyuaj-rau-recycle mus rau cov khoom siv compostable thiab biodegradable nyob rau hauv ib qho kev mob siab los txiav tawm kom muaj nuj nqis ntawm cov pov tseg uas xaus rau hauv landfills.
Txawm hais tias qhov tseeb tias ob nqe lus hais txog ob hom kev ntim khoom sib txawv, lawv qee zaum siv sib hloov txawm tias lawv zoo sib xws.
Cov ntaub ntawv biodegradable thiab compostable txhais li cas?
Cov khoom xyaw uas siv los tsim cov ntim biodegradable yuav maj mam disintegrate rau hauv me me.Qhov khoom thiab ib puag ncig nws nyob rau hauv kev txiav txim siab ntev npaum li cas nws yuav siv sij hawm kom lwj.
Piv txwv ntawm yam uas cuam tshuam rau lub sijhawm degradation yuav siv sijhawm ntev npaum li cas suav nrog lub teeb, dej, qib oxygen, thiab kub.
Technically, ntau yam khoom tuaj yeem raug categorized li biodegradable vim qhov tsuas xav tau yog cov khoom tawg.Txawm li cas los xij, 90% ntawm cov khoom yuav tsum degrade nyob rau hauv rau lub hlis thiaj li yuav tsum tau sau npe raws li biodegradable raws li ISO 14855-1.
Kev ua lag luam rau biodegradable ntim tau ntsib kev loj hlob sai nyob rau xyoo tas los no thiab tau kwv yees tias muaj nqis txog $ 82 nphom hauv xyoo 2020. Ntau lub tuam txhab paub zoo tau hloov mus rau cov khoom lag luam biodegradable lossis cog lus siv lawv ntau dua yav tom ntej, suav nrog Coca-Cola, PepsiCo, thiab Nestle.
Nyob rau hauv sib piv, compostable ntim yog tsim los ntawm cov khoom uas, muab qhov tsim nyog tshwm sim, decompose mus rau hauv biomass (ib tug sustainable zog qhov chaw), carbon dioxide, thiab dej.
Raws li EN 13432 European tus qauv, cov khoom siv compostable yuav tsum tau tawg tsis pub dhau 12 lub lis piam tom qab muab pov tseg.Tsis tas li ntawd, lawv yuav tsum ua kom tiav biodegrading hauv rau lub hlis.
Cov xwm txheej zoo tshaj plaws rau kev ua qoob loo yog qhov chaw sov, qhov chaw ntub dej nrog cov pa oxygen ntau.Qhov no txhawb kev tawg ntawm cov organic teeb meem los ntawm cov kab mob los ntawm cov txheej txheem hu ua anaerobic digestion.
Cov lag luam uas cuam tshuam nrog cov zaub mov tau txiav txim siab ntim cov khoom ntim uas tau hloov pauv cov ntaub ntawv yas lossis biodegradable.Raws li ib qho piv txwv, Conscious Chocolate siv ntim nrog zaub-raws li inks, whereas Waitrose ntiav compostable ntim rau nws cov zaub mov npaj.
Nyob rau hauv qhov tseeb, tag nrho cov biodegradable ntim yog compostable, tab sis tsis yog tag nrho cov compostable ntim yog biodegradable.
Cov txiaj ntsig thiab qhov tsis zoo ntawm kev ntim kas fes compostable
Qhov tseeb tias cov ntaub ntawv compostable decompose rau hauv ib puag ncig kev nyab xeeb organic molecules yog qhov txiaj ntsig tseem ceeb.Qhov tseeb, cov av yuav tau txais txiaj ntsig los ntawm cov tshuaj no.
Hauv tebchaws Askiv, ob ntawm txhua tsib lub tsev muaj kev nkag mus rau cov chaw sib xyaw ua ke lossis cov chiv hauv tsev.Los ntawm kev siv composting kom loj hlob txiv hmab txiv ntoo, zaub, thiab paj, cov tswv tsev tuaj yeem ua kom muaj kev ruaj khov thiab nyiam kab thiab noog ntau dua rau lawv lub vaj.
Kev sib kis kab mob yog ib qho teeb meem nrog cov khoom siv compostable, txawm li cas los xij.Cov khoom siv rov ua dua tshiab hauv tsev raug xa mus rau qhov chaw rov qab cov khoom siv hauv zos (MRF).
Cov khib nyiab khib nyiab tuaj yeem ua rau lwm cov khoom siv rov ua dua tshiab ntawm MRF, ua rau lawv tsis tuaj yeem ua tiav.
Piv txwv li, 30% ntawm cov khoom siv rov ua dua tshiab muaj cov khoom siv rov ua dua tshiab hauv 2016.
Qhov no qhia tau hais tias cov khoom no ua rau muaj kuab paug nyob hauv dej hiav txwv thiab qhov chaw pov tseg.Qhov no hu rau daim ntawv lo kom raug ntawm cov khoom siv compostable kom cov neeg siv khoom pov tseg kom zoo thiab tsis txhob kis mus rau lwm cov khoom siv rov ua dua tshiab.
Biodegradable kas fes ntim: qhov zoo thiab qhov tsis zoo
Cov ntaub ntawv biodegradable muaj ib qho zoo dua li cov compostable: lawv yooj yim dua pov tseg.Cov khoom siv biodegradable tuaj yeem muab pov ncaj qha rau hauv cov thoob khib nyiab los ntawm cov neeg siv khoom.
Tom qab ntawd, cov ntaub ntawv no yuav decompose nyob rau hauv qhov chaw pov tseg los yog lawv yuav hloov mus rau hauv hluav taws xob.Cov ntaub ntawv biodegradable tshwj xeeb tuaj yeem decompose rau hauv biogas, uas tuaj yeem hloov mus rau biofuel tom qab.
Thoob plaws ntiaj teb, kev siv biofuel yog nthuav;Hauv Asmeskas xyoo 2019, nws tau nce 7% ntawm tag nrho cov roj siv.Qhov no txhais tau hais tias cov ntaub ntawv biodegradable tuaj yeem "recycled" rau hauv ib yam dab tsi pab ntxiv rau decomposing.
Txawm hais tias biodegradable cov ntaub ntawv ua decompose, tus nqi ntawm decomposition txawv.Piv txwv li, nws yuav siv lub txiv kab ntxwv tev nyob ib ncig ntawm rau lub hlis kom degrade tag nrho.Ib lub hnab nqa khoom yas, ntawm qhov tod tes, tuaj yeem siv sijhawm txog 1,000 xyoo kom tag nrho decompose.
Thaum cov khoom lag luam biodegradable tau decomposed, nws tuaj yeem cuam tshuam tsis zoo rau ib puag ncig hauv cheeb tsam.
Piv txwv li, lub hnab nqa khoom yas hais ua ntej yuav degrade mus rau hauv cov yas me me uas tuaj yeem ua rau muaj kev phom sij rau cov tsiaj qus.Thaum kawg, cov khoom no tuaj yeem nkag mus rau hauv cov khoom noj khoom haus.
Qhov no txhais li cas rau cov tuam txhab uas ci kas fes?Cov tswv yuav tsum, qhov tseem ceeb tshaj plaws, ua tib zoo xaiv cov ntim khoom uas yog biodegradable tiag tiag thiab yuav tsis kis rau ib puag ncig.
Xaiv qhov kev ua haujlwm zoo tshaj plaws rau koj lub khw kas fes
Txij li ntau lub tebchaws tau txwv tsis pub siv lawv cov kev siv tam sim no, cov yas siv ib zaug tau dhau los ua tsawg thiab tsawg dua hauv kev tos txais qhua.
Tsoomfwv UK twb tau tshaj tawm txoj cai muag cov yas stirrers thiab straws, thiab nws tseem tab tom nrhiav kev tawm tsam cov khob polystyrene thiab cov khoom siv yas ib zaug.
Qhov no txhais tau hais tias yeej tsis tau muaj lub sijhawm zoo dua rau cov tuam txhab kas fes roasting los saib rau hauv cov khoom ntim khoom noj lossis biodegradable.
Qhov kev xaiv twg, txawm li cas los xij, yog qhov zoo rau koj lub tuam txhab?Nws nyob ntawm ntau yam, suav nrog qhov chaw koj lub lag luam nyob, koj yuav tsum siv nyiaj ntau npaum li cas, thiab seb koj puas muaj kev nkag mus rau cov khoom siv rov ua dua tshiab.
Qhov tseem ceeb tshaj plaws yog kom paub tseeb tias koj lub ntim ntim tau sau kom zoo, tsis hais seb koj xaiv siv cov khoom siv compostable lossis biodegradable takeout khob lossis hnab.
Cov neeg muas zaub tau tsiv mus nyob rau hauv lawv tus kheej cov lus qhia mus rau sustainability.Raws li ib txoj kev tshawb fawb, 83% ntawm cov neeg thov koom nrog hauv kev rov ua dua tshiab, thaum 90% ntawm cov neeg txhawj xeeb txog lub xeev ntawm ib puag ncig zoo li nws sawv.
Cov neeg siv khoom yuav nkag siab meej tias yuav ua li cas pov tseg cov ntim hauv eco-phooj ywg yog tias nws raug cim tias yog compostable lossis biodegradable.
Txhawm rau ua kom tau raws li qhov xav tau ntawm kev lag luam, CYANPAK muaj ntau hom kev ntim khoom ntim thiab biodegradable, nrog rau cov ntawv kraft, ntawv nplej, thiab polylactic acid (PLA), uas yog tsim los ntawm cov hmoov txhuv nplej siab.
