Umwanda wa plastike ubangamiye ibidukikije, hamwe na toni zisaga miliyari 9 za plastiki zakozwe kuva mu myaka ya za 1950, na toni miliyoni 8.3 zitangirira mu nyanja zacu buri mwaka.Nubwo hashyizweho ingufu ku isi, 9% gusa bya plastiki byongera gukoreshwa, bigasigara ibyinshi byangiza urusobe rwibinyabuzima cyangwa bigatinda kumyanda mu binyejana byinshi.
Umwe mu bagize uruhare runini muri iki kibazo ni ubwinshi bwibintu bya pulasitiki bikoreshwa rimwe gusa nkimifuka ya pulasitike.Iyi mifuka, ikoreshwa mugihe cyiminota 12 gusa, ikomeza kwishingikiriza kuri plastiki ikoreshwa.Inzira yabo yo kubora irashobora gufata imyaka irenga 500, ikarekura microplastique yangiza ibidukikije.
Ariko, muri izo mbogamizi, plastiki ibora ibinyabuzima itanga igisubizo cyiza.Bikozwe muri 20% cyangwa byinshi bishobora kuvugururwa, bio-plastike itanga amahirwe yo kugabanya kwishingikiriza ku bicanwa by’ibinyabuzima no kugabanya ikirere cyacu.PLA, ikomoka kumasoko y'ibimera nka krahisi y'ibigori, na PHA, ikorwa na mikorobe, ni ubwoko bubiri bwibanze bwa bio-plastiki hamwe nibikorwa byinshi.
Mugihe ibinyabuzima byangiza ibinyabuzima byerekana ibidukikije byangiza ibidukikije, ni ngombwa gusuzuma ingaruka zabyo.Gutunganya imiti nibikorwa byubuhinzi bifitanye isano n’umusaruro wa bioplastique birashobora kugira uruhare mu guhumana no ku kibazo cy’imikoreshereze y’ubutaka.Byongeye kandi, ibikorwa remezo bikwiye byo guta bio-plastiki bikomeza kuba bike, byerekana ko hakenewe ingamba zuzuye zo gucunga imyanda.
Kurundi ruhande, plastiki zisubirwamo zitanga igisubizo gikomeye hamwe nibikorwa byagaragaye.Mugutezimbere gutunganya no gushora imari mubikorwa remezo kugirango tuyishyigikire, turashobora kuvana imyanda ya plastike mumyanda no kugabanya ingaruka kubidukikije.Mugihe plastiki ishobora kwangirika yerekana amasezerano, ihinduka ryubukungu bwizunguruka, aho ibikoresho bikoreshwa kandi bigakoreshwa neza, birashobora gutanga igisubizo kirambye kirambye kubibazo by’umwanda.
