Kedu ihe bụ akpa nwere ike imebi

1.Biodegradation akpa ， Biodegradation akpa bụ akpa ike nke na-decomposed site bacteria ma ọ bụ ndị ọzọ ntule. About 500 ijeri 1 trillion plastic akpa na-eji kwa afọ. Akpa biodegradation bụ akpa nwere ike imebi site na nje bacteria ma ọ bụ ihe ndị ọzọ dị ndụ. A na-eji ihe dị ka ijeri 500 ruo 1 trillion akpa rọba kwa afọ.
2.Distinuish n'etiti "biodegradable" na "compostable"
Na-ahụkarị okwu, okwu biodegradable nwere a dị iche iche pụtara karịa compost.Biodegradable nanị pụtara na ihe nwere ike decomposed site bacteria ma ọ bụ ndị ọzọ ntule, na "compost" na plastic ụlọ ọrụ na-akọwara dị ka ike decompose na aerobic gburugburu ebe obibi nọgidere na-na kpọmkwem. a na-achịkwa ọnọdụ okpomọkụ na ọnọdụ iru mmiri.Compospost bụ ikike nke biodecompose na ubi compost, na-eme ka ihe ndị a na-ahụ anya na-enweghị ike ịmata ma mebie n'ime carbon dioxide, mmiri, ogige inorganic na biomass na ọnụego kwekọrọ.

Ntinye nke "ihe inorganic" wepụrụ ngwaahịa ikpeazụ ka a na-ewere ya dị ka compost ma ọ bụ humus, nke bụ naanị ihe ndị dị ndụ. N'ezie, ọkọlọtọ xxx chọrọ maka plastik ka a na-akpọ compost n'okpuru nkọwa ASTM bụ na ọ ga-apụ n'anya n'otu oge ahụ. tụọ dị ka ihe ọzọ nke mmadụ maraworị ka compost n'okpuru nkọwa ọdịnala. Enwere ike ime akpa rọba site na polymer plastik nkịtị (ya bụ, polyethylene) ma ọ bụ polypropylene wee gwakọta ya na mgbakwunye nke na-akpata mbibi polymer (polyethylene) wee mebie biodegradable n'ihi.
3.Material maka akpa biodegradable

"Ndị ọha na eze na-ahụ biodegradable bụ ihe anwansi," ọ bụ ezie na a na-ejikarị okwu ahụ eme ihe, dị ka RamaniNarayan, onye injinia kemịkalụ na East Lansing Michigan State University na onye ndụmọdụ sayensị na Institute for Biodegradable Plastics si kwuo. na okwu ezighi ezi n'ime akwụkwọ ọkọwa okwu anyị. N'ime mpaghara mkpofu nke Greater Pacific, plastic biodegradable na-akụda n'ime obere iberibe nke nwere ike ịbanye n'usoro nri ngwa ngwa site na iri ya.
4.Mwegharị nke akpa ndị na-emebi emebi.
Enwere ike ịmegharị ihe mkpofu n'ime osisi, ma ọ na-esiri ike ịhazi ma megharịa ya mgbe e risịrị ya. Polymers dabeere na bio nwere ike imerụ ihe eji eme ihe nke polymers ndị ọzọ na-emekarị. ndị na-emegharị ihe agaghị anabata ha n'ihi na ọ dịghị ọmụmụ ogologo oge na-enwe ike ịmegharị ngwaahịa ndị nwere ihe mgbakwunye ndị a. Tụkwasị na nke ahụ, Institute for Biodegradable Plastics (BPI) kwuru na nhazi nke ihe mgbakwunye na ihe nkiri oxidized dịgasị iche iche, nke na-ewebata mgbanwe ndị ọzọ. n'usoro imegharị ihe.
