European Bioplastics ntseeg hais tias nws yog ib qho tseem ceeb uas cov kev cai tshiab xav txog thiab txhawb nqa qhov tseem ceeb ntawm cov hnab ntim khoom, uas tuaj yeem nqa tau ntau yam txiaj ntsig rau composting thiab organic pov tseg.
Lub hom phiaj txhawm rau txheeb xyuas cov xwm txheej rau av kev noj qab haus huv thiab kev kho av. Av yog ib qho tseem ceeb uas tsis yog rov tsim dua tshiab uas ua lub luag haujlwm tseem ceeb hauv peb lub neej los ntawm kev muab zaub mov noj qab haus huv thiab cov khoom siv ruaj khov rau cov pej xeem hauv ntiaj teb.
Cov hnab yas compostable pab cais cov biowaste collections thiab tseem tuaj yeem khaws cov khoom noj uas khi rau hauv lub ntim, uas yuav muab pov tseg yog tias lub ntim tau sieved los ntawm cov dej khib nyiab. Lawv kuj txo cov pa phem ntawm cov khoom siv hauv cov khoom sib xyaw, txo cov dej noo thiab ua kom cov khoom loj tuaj, uas yuav pab tau thaum cov khoom noj khib nyiab composted.
Tus nqi ntawm industrially compostable plastics (tso ntawv pov thawj raws li kev sib haum xeeb nyob sab Europe tus qauv EN 13432) yog tias lawv tuaj yeem rov ua dua tshiab raws li kev xaiv pov tseg ntxiv thiab muab txoj hauv kev zoo dua rau kev cais cov khoom noj hauv tsev. Ib qho piv txwv tseem ceeb yog compostable plastics hauv ltalis, qhov twg compostable ntim tau dav txhawb thiab siv. Hauv xyoo 2018, tus neeg rov ua dua tus nqi ntawm cov khib nyiab hauv tsev mus txog 80%.
Los ntawm kev txhim kho cov khoom sib cais ntawm cov organic pov tseg, cov khoom siv hauv cov khoom siv compostable kuj pab txo cov pa phem ntawm cov khib nyiab pov tseg los ntawm cov khoom siv niaj hnub thiab thaum kawg txo cov microplastics hauv fossil-based polymers hauv compost. Vim hais tias biodegradable polymers tsis tawg mus rau hauv cov microplastics mus tas li thaum lawv degrade, cov kab mob uas muaj peev xwm ntawm metabolizing cov polymers no muaj nyob rau hauv ib puag ncig ntuj. Yog li ntawd, biodegradable plastics pab txo qhov cuam tshuam ib puag ncig thiab txo qis cov khoom ntawm microplastic hauv ntau qhov chaw.
Cov av biodegradable mulch yog ib qho piv txwv zoo ntawm kev lag luam siv biodegradable plastics. Lawv tau nyob rau hauv kev ua lag luam tau ntau xyoo thiab ua lub luag haujlwm tseem ceeb hauv kev ua liaj ua teb niaj hnub no vim lawv pab ua kom cov qoob loo nce ntxiv, txhim kho qoob loo zoo, txhim kho kev tswj cov nroj tsuag, thiab txo cov dej thiab tshuaj tua kab. Piv rau cov pa yas (PE) mulch, av biodegradable mulch tag nrho biodegrades hauv tsawg dua ob xyoos thiab tsis sib sau hauv av. Qhov zoo piv nrog cov tsoos mulch kuj tau lees paub los ntawm United Nations. Av kev noj qab haus huv kuj tseem muaj kev tiv thaiv los ntawm cov txheej txheem ntawv pov thawj nruj. Cov txheej txheem European EN 17033 tau teeb tsa cov kev xav tau meej rau biodegradation ntawm mulch films siv hauv kev ua liaj ua teb thiab horticulture.
Thaum tsim txoj cai lij choj tshiab kev noj qab haus huv hauv av, European Commission yuav tsum xav txog cov pa roj carbon monoxide uas organic recycling tsim. Qee cov pa roj carbon khaws cia hauv bio-kua pov tseg hloov mus rau hauv cov chiv los ntawm kev siv cov organic tuaj yeem hloov mus rau ib daim ntawv ruaj khov thiab nyob hauv av tau ntau xyoo. Vim tias cov khoom siv hauv cov khoom siv compostable pab xa ntau cov biowaste rau hauv cov organic recycling, lawv pab tsim cov pa roj carbon monoxide thiab pab txo cov pa roj carbon dioxide.
