Amacupa ya plastikibyahindutse igice cyingenzi mubuzima bwacu bwa buri munsi.Turabikoresha mukubika amazi, ibinyobwa, ndetse nogusukura urugo.Ariko wigeze ubona ibimenyetso bito byanditse munsi yaya macupa?Bafite amakuru yingirakamaro yubwoko bwa plastiki yakoreshejwe, amabwiriza yo gutunganya, nibindi byinshi.Muri iyi blog, tuzasesengura ibisobanuro biri inyuma yibi bimenyetso nakamaro kabyo mugusobanukirwa plastike dukoresha.
Amacupa ya plastiki yanditseho ikimenyetso cya mpandeshatu kizwi nka Resin Identification Code (RIC).Iki kimenyetso kigizwe numubare kuva 1 kugeza 7, ukikijwe no kwiruka imyambi.Buri mubare ugereranya ubwoko butandukanye bwa plastiki, bufasha abaguzi nibikoresho byo gutunganya kubimenya no kubitondekanya.
Reka duhere ku kimenyetso gikunze gukoreshwa, umubare 1. Yerekana Polyethylene Terephthalate (PET cyangwa PETE) - plastike imwe ikoreshwa mumacupa y’ibinyobwa bidasembuye.PET yemerwa cyane na progaramu ya recycling kandi irashobora gukoreshwa mumacupa mashya, fibre yuzuye amakoti, ndetse na tapi.
Tujya kuri numero 2, dufite Polyethylene Yinshi (HDPE).Iyi plastiki ikunze gukoreshwa mu nkono y’amata, amacupa yo kumesa, no mu mifuka y'ibiryo.HDPE nayo irashobora gukoreshwa kandi igahinduka ibiti bya pulasitike, imiyoboro, hamwe n’ibikoresho byo gutunganya.
Umubare 3 uhagarariye Polyvinyl Chloride (PVC).PVC ikunze gukoreshwa mu miyoboro y'amazi, gufata firime, no gupakira ibisebe.Nyamara, PVC ntabwo ishobora gukoreshwa byoroshye kandi itera ingaruka kubidukikije mugihe cyo kuyikora no kuyijugunya.
Umubare 4 ugereranya Polyethylene nkeya (LDPE).LDPE ikoreshwa mumifuka y'ibiryo, gupfunyika plastike, no kumacupa.Mugihe ishobora gutunganywa kurwego runaka, ntabwo gahunda zose zisubiramo zirabyemera.Imifuka ikoreshwa na firime ya pulasitike bikozwe muri LDPE yongeye gukoreshwa.
Polypropilene (PP) ni plastiki igaragazwa numubare 5. PP ikunze kuboneka mubikoresho bya yogurt, imipira yamacupa, hamwe nibikoresho bikoreshwa.Ifite ingingo yo hejuru yo gushonga, bigatuma iba nziza kuri kontineri itekanye.PP irashobora gukoreshwa kandi igahinduka amatara yerekana ibimenyetso, ububiko bwabitswe, hamwe na bateri.
Umubare 6 ni uwa Polystirene (PS), uzwi kandi nka Styrofoam.PS ikoreshwa mubikoresho byo gufata, ibikombe bikoreshwa, hamwe nibikoresho byo gupakira.Kubwamahirwe, biragoye gusubiramo kandi ntibyemewe na gahunda nyinshi zo gutunganya ibicuruzwa kubera agaciro kayo ku isoko.
Ubwanyuma, nimero 7 ikubiyemo izindi plastiki zose cyangwa imvange.Harimo ibicuruzwa nka polyakarubone (PC) bikoreshwa mumacupa y’amazi yongeye gukoreshwa, hamwe na plastiki ishobora kwangirika ikozwe mu bikoresho bishingiye ku bimera, hamwe n’ibikoresho bya Tritan biva muri Eastman, na Ecozen biva mu miti ya SK.Mugihe bimwe mubya plastiki 7 byasubirwamo, ibindi sibyo, kandi kubijugunya neza nibyingenzi.
Gusobanukirwa nibi bimenyetso hamwe na plastiki bihuye birashobora gufasha cyane mukugabanya imyanda no guteza imbere uburyo bwiza bwo gutunganya.Mu kumenya ubwoko bwa plastike dukoresha, turashobora gufata ibyemezo byuzuye bijyanye no kongera gukoresha, gutunganya, cyangwa kubijugunya neza.
Igihe gikurikira ufashe icupa rya plastiki, fata akanya urebe ikimenyetso munsi hanyuma urebe ingaruka zacyo.Wibuke, ibikorwa bito nka recycling birashobora guhuriza hamwe bigira uruhare runini mukurengera ibidukikije.Hamwe na hamwe, reka duharanire ejo hazaza heza kandi harambye.
