Nigute gupakira plastike bishobora gukoreshwa? Ni ubuhe buryo bw'ikoranabuhanga bukwiye kwitabwaho?
Muriyi mpeshyi, gupakira plastike byibasiye amakuru buri gihe! Ubwa mbere, icupa ry’icyatsi kibisi 7 mu Bwongereza ryahinduwe ripakirwa mu mucyo, hanyuma Mengniu na Dow bamenya inganda za firime zigabanuka ubushyuhe burimo ibikoresho bya PCR. Nibwo bwa mbere Mengniu agerageza gukoresha PCR mubipfunyika bwa kabiri.
Hariho kandi uruganda rukora ice cream mpuzamahanga foneri (umushinga uhuriweho na Finch na RR) watumije miriyoni 100 Z Zisubiramo polypropilene ice cream ibikombe. Ice cream ipakiwe muri polypropilene itunganijwe izagurishwa mu Butaliyani.
Igitekerezo cyibanze cyo guhanga udushya twa tekinoroji ya plastike muri ibi byiciro bitandukanye ni kimwe: gusubiramo ibicuruzwa ntibikiri intero, ahubwo ni umurwanashyaka "ufite ishingiro". Ibipapuro bisubirwamo birashobora kugira uruhare runini.
Nk’uko repot na dat zibitangaza, isoko ryo gupakira ibintu bya pulasitiki rirambye ku isi biteganijwe ko rizagera kuri miliyari 127.5 z'amadolari ya Amerika mu 2028, hamwe n’ubwiyongere bw’umwaka buri mwaka bwa 6%, muri byo hakaba hashobora gutunganywa ibicuruzwa byinshi.
Nigute gupakira plastike bishobora gukoreshwa? Ni ubuhe buryo bw'ikoranabuhanga bukwiye kwitabwaho?
01 ibikoresho bimwe bitezimbere cyane agaciro koroheje ko gupakira gutunganya
Mu myaka yashize, igisubizo kimwe cyibikoresho byo gupakira hamwe nigiciro cyiza cyo gutunganya cyashyizwe ahagaragara, kandi cyageze ku gusimbuza ibikoresho bitandukanye byahujwe mubisabwa bimwe. Ugereranije nibikoresho byinshi bigize ibikoresho, ibikoresho bya pulasitiki bipfunyika ntibikeneye kwamburwa nyuma yo kubikoresha, kandi agaciro gakoreshwa neza kanozwa cyane. Haba mubipfunyika bikomeye cyangwa bipfunyitse byoroshye, ibikoresho bimwe birubahwa cyane.
Kurugero: demetallised yuzuye PE pompe umutwe
Mubikoresho bya buri munsi bipakira imiti, umutwe wa pompe gakondo urashobora kuba urimo ibikoresho bitandukanye, kandi rimwe na rimwe, birashobora no kugora inzira yo gutunganya. Ubu bwoko bwa pompe ifite plastike nicyuma kivanze byongera ubunyangamugayo bwo gupakira no gutunganya.
Undi urugero: ibiryo byose bya PE byoroshye gupakira ni ogisijeni irwanya kandi itangiza amazi
Mu rwego rwibiryo byoroshye gupakira, gupakira ibintu byinjiye buhoro buhoro mubiribwa byabana n’ibikomoka ku mata. Kurugero, uruganda rwa Garbo rutanga ibikoresho bimwe byabana bipfunyika ibiryo byigitoki kama mango puree. Mugereranije, gupakira firime hamwe nibikoresho bimwe byoroshye gusubiramo.
02 icupa rya PET icupa kumena icupa ryamabara icupa biragoye
Mugutunganya amacupa ya PET, amacupa yamabara ya PET bizongera ingorane zo gutunganya nyuma kandi bigabanye agaciro kayo, mugihe amacupa ya PET abonerana aroroshye kubyongera. Mubyongeyeho, amacupa ya PET abonerana nayo yoroshye kuzamura ubwiza bwibicuruzwa.
Kubwibyo, amacupa ya transparent et et yarushijeho kumenyekana mumyaka ibiri ishize. Coca Cola yahinduye icupa ryayo ryurubura rimaze imyaka 50 riva mubyatsi rihinduka umucyo mumyaka ibiri ishize, naho barindwi mubwongereza nabo bazatangira muriyi mpeshyi kugirango bahindure ibipaki 375m, 500m na 600ml FET kuva mubara ryambere ryambere kugirango babone gukorerwa nyuma. Usibye Coke Sprite hamwe no gupakira ibintu birindwi bisobanutse, uruganda rukora amata ya agenlian mastelene HNOS ruzanatangira gukoresha icupa rya PET risobanutse ryakozwe na Amcor kugirango ryuzuze amata mashya.
03 ongera ukoreshe PCR uhindure imyanda mubutunzi
Izina ryuzuye rya PCR ni posita umuguzi wongeyeho, bivuze ko umuguzi yongeye gukoreshwa mu gishinwa, cyangwa PCR mugihe gito. Ubusanzwe ikozwe mubice bishya bya pulasitike nyuma yo gutunganya imyanda ya plastike no gutondeka, gusukura nuduce twumuhanda na sisitemu yo gutunganya. Iyi plastike ya plastike ifite imiterere imwe na plastiki mbere yo kuyitunganya. Iyo ibice bishya bya pulasitike bivanze na resin yumwimerere, ibicuruzwa bitandukanye bya plastiki birashobora gukorwa. Ubu buryo ntibugabanya gusa imyuka ya karuboni, ahubwo binagabanya gukoresha ingufu. PCR irashobora gukoreshwa mubikoresho byamatungo, PE, PP, HDPE, nibindi
Amabwiriza y’ubumwe bw’ibihugu by’Uburayi ashishikariza ibigo kunoza imikoreshereze ya PCR
Amabwiriza y’ubumwe bw’ibihugu by’Uburayi arasaba ko igipimo cy’ibikoresho bya pulasitiki bitunganyirizwa mu icupa ry’ibikoresho bya kabiri bigomba kongerwa kugera kuri 25% guhera mu 2025. Kuva mu 2030, igipimo cy’ibikoresho bya pulasitiki byongeye gukoreshwa mu macupa y’ibinyobwa bya pulasitike bigomba kugera kuri 30%, ibikoresho bya PCR muri gupakira bingana na 30%, nibikoresho bya PCR hamwe nintego ya Groupe ya Eurasia ni 40%.
Kongera igipimo cyibikoresho bya PCR mubipfunyika byabaye imwe mungamba zingenzi zinganda za FMCG kugirango zigere ku cyerekezo 2025 cyangwa icyerekezo 2030. Unilever irateganya kugera kuri 25% byibikoresho bya PCR mubipfunyika bitarenze 2025, naho itsinda rya Mars rirateganya kugera kubipfunyika muri 2025. Muri Kamena uyu mwaka, Coca Cola yakomeje kwagura imiterere irambye i Burayi kandi iteza imbere umusaruro no gukoresha amacupa ya PET mu Butaliyani no mu Budage. Mbere, yatangaje ko izatanga buhoro buhoro amacupa y’amatungo 100% mu Buholandi, Noruveje, Suwede n'ahandi.
