Ibikoresho byangirika birashobora kugabanywa mubyiciro bine: plastiki ishobora gufotorwa, plastiki ibora, ifoto / ibinyabuzima byangiza ibidukikije hamwe na plastiki yangirika.Amashanyarazi ya Photodegradable ni fotosensiseri ivanze muri plastiki.Munsi yumucyo wizuba, plastiki zirabora buhoro buhoro.Ariko ibibi byayo ni uko igihe cyo kwangirika kigira ingaruka ku zuba ndetse n’ikirere, bityo ntigishobora kugenzurwa.Ibinyabuzima byangiza ibinyabuzima bivuga plastiki zishobora kubora mo molekile nkeya hamwe na mikorobe ibaho muri kamere, nka bagiteri, ibumba, na algae mu bihe bimwe na bimwe.Bene plastike ziroroshye kubika no gutwara, kandi zifite uburyo bwinshi bwo gusaba.Umucyo / ibinyabuzima byangiza plastike ni plastiki ihuza ibintu bibiri biranga plastiki yangirika n’umucyo na plastiki ibora.Kugeza ubu, plastiki ya biodegradable yakozwe mu gihugu cyanjye ni cyane cyane biopolyester nka aside polylactique (PLA), polyhydroxyalkanoate (PHA), copolymer ya karuboni (PPC) nibindi.Acide Polylactique (PLA) ikorwa na polymerisation ya monomers ya lactide ikurwa mu isukari y’ibimera, kandi irashobora kwangirika rwose mu mazi na dioxyde de carbone munsi y’ifumbire mvaruganda.Polyhydroxyalkanoates (PHA) ni kopi ya alifatique ifite imiterere itandukanye ikomatanyirizwa hamwe no gusembura amasoko atandukanye ya karubone na mikorobe.Ntibishobora gukoreshwa gusa mubikoresho byo gupakira, firime yubuhinzi, nibindi, ariko birashobora no gukoreshwa cyane mubuvuzi, kwisiga, no kugaburira amatungo nizindi nzego.Amashanyarazi yangirika ni plastiki zishobora gushonga mumazi kubera kongeramo ibintu bikurura amazi.Hamwe niterambere ryibinyabuzima bigezweho, plastiki yibinyabuzima yahindutse ahantu hashyushye mubushakashatsi niterambere.
Mubushinwa, tekinoroji yibikoresho bigezweho ntabwo ikuze bihagije, kandi hazaba harimo inyongeramusaruro.Niba ibyo byongeweho byongeweho, ibikoresho bya plastiki ntabwo bizagera ku ngaruka za biodegradation.Niba itongeyeho, ibi bikoresho bya pulasitike bizangirika mubihe byose, cyane cyane ahantu h'ubushyuhe bwo hejuru, kubwibyo biragoye kubika cyane.
Mubyongeyeho, gukoresha ibikoresho biodegradable kugirango ukore ibicuruzwaibishushanyobisaba guhinduka byihariye.
