Ob qho tib si compostable thiab biodegradable koom nrog ntuj degradation los yog tawg ntawm cov organic teeb meem rau hauv av los ntawm microbial digestion, txawm hais tias ob lo lus tsis sib hloov.
1. Dab tsi yog "compostable"?
Yog hais tias cov khoom yog compostable, nws txhais tau hais tias nyob rau hauv composting tej yam kev mob (kub, humidity, oxygen, thiab muaj cov kab mob) nws yuav decompose rau hauv CO2, dej, thiab as-ham compost nyob rau hauv ib lub sij hawm tshwj xeeb.
2. Vim li cas "compostable" zoo dua "biodegradable"?
Yog tias koj lub hnab ntim tau sau tias "Compostable," koj tuaj yeem paub tseeb tias nws yuav tawg mus txog 180 hnub hauv cov xwm txheej compostable. Qhov no zoo ib yam li cov zaub mov thiab vaj pov tseg tau tawg los ntawm cov kab mob, tawm hauv cov khoom tsis muaj tshuaj lom.
3. Vim li cas compostability tseem ceeb?
Cov hnab ntim cov hnab yas yooj yooj yim feem ntau muaj paug cov khoom noj uas tsis tuaj yeem rov ua dua tshiab thiab xaus rau hauv incineration lossis landfill. Yog vim li cas compostable ntim tuaj rau hauv lub neej. Tsis tsuas yog nws tsis txhob muab pov tseg thiab incineration, tab sis lub resulting compost rov qab organic teeb meem rau cov av. Yog tias ntim cov khib nyiab tuaj yeem muab tso rau hauv cov khoom siv pov tseg thiab siv los ua compost (cov av nplua nuj) rau lwm tiam ntawm cov nroj tsuag, ces cov pov tseg yog rov siv dua thiab siv tau rau kev ua lag luam, tsis tsuas yog "khoom khib nyiab", tab sis muaj nyiaj txiag ntau. tus nqi.
4. Dab tsi yog qhov txawv ntawm lub tsev thiab lub thawv ntim khoom lag luam lossis kev lag luam?
Cov thawv ntim hauv tsev muaj peev xwm me dua thiab feem ntau raug rau qhov kub thiab txias. Hauv qhov no, cov khoom siv compostable yuav decompose hauv 180 hnub.
Commercial lossis industrial composting ntim muaj peev xwm loj dua, yog li ntawd, ntau qhov cua sov yog tsim nyob rau hauv industrial composting ntim (45-60 degree), uas accelerates biodegradation. Tib cov khoom siv compostable feem ntau tawg hauv kev lag luam compost nyob rau hauv 90 hnub, txog ib nrab ntev li ntawm tsev neeg compost.
