Na Maachị 2022, Mgbakọ gburugburu gburugburu UN nke ise gara n'ihu gafere "Mkpebi Mmetọ Plastic (Draft)" na Nairobi, isi obodo Kenya. Na nzukọ ahụ, onye isi ala, minista gburugburu ebe obibi na ndị nnọchiteanya ndị ọzọ sitere na mba 175 bịanyere aka na akụkọ ihe mere eme a. Mkpebi a bụ ịkwalite ọchịchị zuru ụwa ọnụ nke ibelata mmetọ rọba ma nwee olileanya ịkwụsị mmetọ rọba n'afọ 2024.
Nlebara anya nke ihe ndị na-emebi emebi
Dị ka akụkọ gburugburu ebe obibi gara aga nke OECD (Organization for Economic Co-operation and Development) wepụtara, na 2019, mmepụta nke ngwaahịa rọba ụwa kwa afọ bụ ihe dị ka nde tọn 460, na mkpofu plastik kwa afọ eruola nde 353. Ngwaahịa mmepụta, gụnyere nkwakọ ngwaahịa rọba (40%), ngwongwo ndị ahịa rọba (12), akwa (11%), wdg.
Site na mmepe nke amụma, ihe ndị nwere ike imebi ihe ga-aga n'ihu na-abawanye.
Asọmpi ike nke mmepụta
Ka ọ dị ugbu a, plastic na-emebi emebi n'ahịa nwere ike kewaa ụzọ abụọ: "base petroleum" na "base biological base". A na-ekewa ihe dị iche n'etiti abụọ ahụ na mmepụta akụrụngwa. A na-emepụta rọba na-emebi emebi nke sitere na mmanụ ala dabere na ike fosil, ọkachasị gụnyere PBS (polynoxylxylxylxyl glycol), PBAT (glycolic glycolic glycolin na phenyl -dysteenol (polima nkịtị), PCL (polycopide), wdg. na ọka, ahịhịa na ihe ndị ọzọ dị ndụ, gụnyere PLA (polylactic acid) na PHA (polyxide alkyl).
N'ime ihe ndị dị n'elu a kpọtụrụ aha n'elu, ma e jiri ya tụnyere ihe ndị ọzọ na-emebi emebi, PLA (polyal acid) na ọnụ ahịa PBAT dị ntakịrị, na usoro mmepụta ahụ tozuru oke. Isi ihe ọzọ nke plastik omenala.
Ngwa ngwa nke PLA bụ ọka na ahịhịa. Mgbe ejiri ya mee ihe, enwere ike imebi ya ngwa ngwa n'ime carbon dioxide, mmiri na nnu inorganic n'okpuru ọnọdụ compost (compost ụlọ ọrụ). Mmepụta (PLA) na-etolite okirikiri carbon.
