Gịnị bụ compostable ihe?

Mbibi nke Compostable bụ njedebe nke mbibi, nhazi nke gburugburu ebe obibi microbial, oge mbibi, ọkọlọtọ na mmetụta na gburugburu ebe obibi. European Union nwere nkọwa maka nke a, nke a kọwara dị ka "ihe compostable". Dabere na EN13432, ihe ndị a na-emepụta compost ga-egosiputa njirimara nke biodegradability, ya bụ, ikike nke ihe ndị na-emepụta ihe iji gbanwee CO2 n'okpuru ọrụ nke microorganisms. Eziri ihe a site na usoro nyocha usoro nyocha: en14046 (gosiputara dị ka iso14855: biodegradability under achịkwa composting ọnọdụ). Iji gosipụta mbibi biodegradability zuru oke, opekata mpe 90% nke larịị biodegradation ga-eru na ihe na-erughị ọnwa isii.


EU nyere iwu banyere ihe ndị na-emebi emebi

Mbibi a tụrụ na ule compost pilot (en14045), ya bụ mpekere na ọnwụ nke ọhụụ (enweghị mmetọ a na-ahụ anya) na compost ikpeazụ. A na-eji ihe mkpofu na-egbu egbu jupụta ihe nlere nke ihe nyocha. A na-atụzi compost ikpeazụ site na sieve 2 mm. Ihe odide fọdụrụ nke ihe nnwale nwere nha> 2mm ga-erughị 10% nke ihe mbụ ahụ.


Usoro usoro ihe compostable

Enweghị mmetụta na-adịghị mma na usoro ịkọpụta ala, nke nyocha ule compost na-enyocha. Obere ala nke ọla di ala (n'okpuru ihe kacha enye) na enweghi mmetụta na-adịghị mma na ịkọchasị ikpeazụ (ntụgharị mbelata ụkpụrụ agronomic na ọnụnọ nke mmetụta ecotoxicological na uto osisi). A na-etinye ule na-eto eto (oecd208 gbanwere) na nyocha ndị ọzọ na physicochemical na compost ebe nbibi nke ule ule mere.
