Phau Ntawv Qhia Qhov Kawg rau Compostable Ntim Cov Khoom

Npaj siv lub ntim compostable? Nov yog txhua yam koj yuav tsum paub txog cov khoom siv compostable thiab qhia koj cov neeg siv khoom li cas txog qhov kawg ntawm-

Dab tsi yog bioplastics?

Bioplastics yog cov yas uas yog bio-based (ua los ntawm cov khoom siv txuas ntxiv dua tshiab, zoo li zaub), biodegradable (muaj peev xwm tawg tau ib txwm muaj) lossis ob qho tib si ua ke. Bioplastics pab txo peb txoj kev cia siab rau cov roj fossil rau kev tsim cov yas thiab tuaj yeem ua los ntawm pob kws, taum pauv, ntoo, siv roj ua noj, algae, qab zib thiab lwm yam. Ib qho ntawm feem ntau siv bioplastics hauv ntim yog PLA.

PLA yog dab tsi?

PLA sawv cev rau polylactic acid. PLA yog ib qho thermoplastic compostable tau los ntawm cov nroj tsuag rho tawm xws li pob kws los yog qab zib thiab yog carbon-neutral, edible thiab biodegradable. Nws yog lwm txoj hauv kev zoo tshaj plaws rau fossil fuels, tab sis nws kuj yog cov khoom siv nkauj xwb (tshiab) uas yuav tsum tau muab rho tawm los ntawm ib puag ncig. PLA disintegrates tag nrho thaum nws tawg es tsis crumbling rau hauv micro-plastics puas.

PLA yog tsim los ntawm kev cog qoob loo ntawm cov nroj tsuag, zoo li pob kws, thiab tom qab ntawd tawg mus rau hauv cov hmoov txhuv nplej siab, protein thiab fiber ntau los tsim PLA. Thaum qhov no yog cov txheej txheem rho tawm tsis zoo dua li cov yas yas, uas yog tsim los ntawm fossil fuels, qhov no tseem muaj peev xwm siv tau thiab ib qho kev thuam ntawm PLA yog nws tshem tawm thaj av thiab cov nroj tsuag uas siv los pub tib neeg.

Xav siv cov ntim ntim compostable? Muaj ob qhov zoo thiab qhov tsis zoo ntawm kev siv cov khoom siv no, yog li nws them nyiaj rau qhov zoo thiab qhov tsis zoo rau koj lub lag luam.

Pros

Compostable ntim muaj cov pa roj carbon me me dua li cov yas yas. Cov bioplastics siv nyob rau hauv compostable ntim yuav ua rau tsawg tsawg lub tsev xog paj gasses nyob rau hauv lawv lub neej tshaj li niaj hnub fossil-roj ua cov yas. PLA raws li bioplastic siv 65% tsawg zog los tsim dua li cov yas yas thiab tsim 68% tsawg dua lub tsev cog khoom gasses.

Bioplastics thiab lwm hom kev ntim khoom ntim tau tawg sai heev thaum piv rau cov yas ib txwm siv, uas tuaj yeem siv sijhawm ntau dua 1000 xyoo los decompose. Noissue's Compostable Mailers yog TUV Austria certified kom tawg tsis pub dhau 90 hnub hauv kev lag luam compost thiab 180 hnub hauv tsev compost.

Nyob rau hauv cov nqe lus ntawm ncig, compostable ntim lov mus rau hauv cov khoom uas muaj nplua nuj nyob rau hauv uas yuav siv tau raws li ib tug fertilizer nyob ib ncig ntawm lub tsev los txhim kho av noj qab haus huv thiab ntxiv dag zog rau ib puag ncig ecosystems.
