Biodegradability

Biodegradability na-ezo aka n'ikike ihe onwunwe nwere imebi mmebi ndu, na-emepụta CO₂, H₂O, methane, biomass na nnu ịnweta. Microorganisms, bụ isi nke ihe mkpofu organic na-enye nri, na-akwalite usoro a. Otú ọ dị, okwu ahụ enweghị nkọwapụta, dịka ihe niile na-emecha biodegrade, na-emesi ike mkpa ọ dị ịkọwapụta gburugburu ebe a chọrọ maka biodegradation.

Compostability

Compost na-agụnye mgbaze microbial iji kwatu ihe mkpofu organic ka ọ bụrụ compost, bara uru maka nkwalite ala na fatịlaịza. Okpomọkụ kacha mma, mmiri na ikuku oxygen dị mkpa maka usoro a. N'ime ikpo ihe mkpofu organic, ọtụtụ ụmụ irighiri ihe na-eri ihe, na-eme ka ha ghọọ compost. Compostability zuru oke chọrọ ịgbaso ụkpụrụ siri ike dị ka European Norm EN 13432 na US Standard ASTM D6400, na-eme ka ire ere zuru oke na-enweghị ihe fọdụrụ na-emerụ ahụ.

Ụkpụrụ mba ụwa

Ewezuga European Standard EN 13432, mba dị iche iche nwere ụkpụrụ nke ha, gụnyere US Standard ASTM D6400 na Australian norm AS4736. Ụkpụrụ ndị a na-arụ ọrụ dị ka ihe nrịbama maka ndị na-emepụta ihe, ndị na-ahụ maka nhazi, akụrụngwa compost, ụlọ ọrụ asambodo, na ndị na-azụ ahịa.

Nkarịrị maka akụrụngwa Compostable

Dị ka European Standard EN 13432 si kwuo, ihe ndị nwere ike imebi ga-egosipụta:

• Biodegradability nke opekata mpe 90%, na-atụgharị na CO₂n'ime ọnwa isii.
• Mgbasa, na-ebute ihe na-erughị 10% fọdụrụnụ.
• Ndakọrịta na usoro compposting.
• Ọkwa dị ala nke ọla dị arọ, na-emebighị ogo compost.

Biodegradability naanị adịghị ekwe nkwa compostability; ihe ga-agbajikwa n'ime otu okirikiri composting. N'aka nke ọzọ, ihe ndị na-ekewa n'ime obere mkpirisi na-abụghị ihe ndị na-emebi ihe n'ime otu okirikiri anaghị ewere dị ka ihe na-agbakọta.
