Nkwakọ ngwaahịa na-emebi emebi na-ezo aka na usoro mmepụta ka ịgbakwunye ụfọdụ ihe mgbakwunye (dịka starch, starch gbanwetụrụ ma ọ bụ cellulose ọzọ, photosensitizer, onye na-ahụ maka biodegradative, wdg), nke mere na nkwụsi ike nke akpa nkwakọ ngwaahịa rọba, wee jiri ya tụnyere mfe iji mebie na gburugburu ebe obibi. Akpa nkwakọ ngwaahịa na-emebi emebi na-ezo aka na akpa nkwakọ ngwaahịa rọba na-emebi kpamkpam n'ime mmiri na carbon dioxide. A na-edozi isi ihe a na-emebi emebi n'ụzọ zuru ezu ka ọ bụrụ lactic acid, ya bụ PLA, site na ọka na akpụ.

Polylactic acid (PLA) bụ ụdị mkpụrụ ndụ ọhụrụ na ihe nwere ike imegharịgharị.

Ka ọ dị ugbu a, ihe ndị bụ isi nke bio-based nke akpa nkwakọ ngwaahịa na-emebi emebi bụ nke PLA + PBAT, nke nwere ike imebi kpamkpam n'ime mmiri na carbon dioxide n'ime ọnwa 3-6 n'okpuru ọnọdụ nke composting (60-70 degrees), na-enweghị mmetọ na gburugburu ebe obibi.
