Binyuze mu mbaraga zidashira z’ibisekuru byinshi bya chimiste naba injeniyeri, plastiki ziva muri peteroli, amakara, na gaze karemano zahindutse ibikoresho byingirakamaro mubuzima bwa buri munsi kubera uburemere bwabyo, uburebure, ubwiza, nigiciro gito.Nyamara, mubyukuri nibyiza bya plastike nabyo biganisha kumyanda myinshi ya plastike.Ibicuruzwa bya plastiki nyuma y’abaguzi (PCR) byabaye imwe mu nzira zingenzi zo kugabanya umwanda w’ibidukikije no gufasha inganda n’inganda gukora "kutabogama kwa karubone".
Ibicuruzwa nyuma yumuguzi byongeye gukoreshwa (PCR) bikozwe mumyanda ya plastike yajugunywe nabaguzi.Pellet nshya ya pulasitike ikorwa mugukusanya imyanda ya plastike kumugezi wa recycling hanyuma ikanyura muburyo bwo gutondeka, gusukura, no gutondagura uburyo bwa sisitemu yo gutunganya imashini.Ibishishwa bishya bya plastike bifite imiterere imwe na plastiki mbere yo kuyitunganya.Iyo pellet nshya ya plastike ivanze nisugi yisugi, hakorwa ibicuruzwa bitandukanye bya plastiki.Ubu buryo, ntibugabanya gusa imyuka ihumanya ikirere, ahubwo binagabanya gukoresha ingufu.
——Dow yashyize ahagaragara ibikoresho birimo 40% PCR
Muri 2020, Dow (DOW) yateje imbere kandi igurisha ibicuruzwa bishya nyuma yumuguzi wongeye gukoreshwa (PCR) byateguwe kugirango bigabanuke ubushyuhe bwa firime mukarere ka Aziya ya pasifika.Ibisigarira bishya birimo 40% nyuma yumuguzi wongeye gukoreshwa kandi birashobora gukora firime zifite imitungo isa nisugi.Ibisigarira birashobora gukoreshwa 100% murwego rwo hagati rwa firime igabanuka yubushyuhe, kugirango ibikubiye mubikoresho bitunganijwe neza muburyo rusange bwa firime ishobora kugabanuka bishobora kugera kuri 13% ~ 24%.
Dow nshya nyuma yumuguzi yongeye gukoreshwa (PCR) yakozwemo resin itanga kugabanuka neza, gukomera no kuramba.Hamwe no gukenera ubucuruzi bwa e-ubucuruzi, burambye, bupakira neza burashobora kurinda ibicuruzwa murwego rwo gutanga no kugabanya imyanda kubakoresha.
Iyi PCR isubiramo ibikoresho byakozwe mugukoresha firime igabanya ubushyuhe itanga ingwate yo gupakira cluster hamwe nogutwara umutekano mubikorwa byo gupakira hamwe nigipimo cyiza cyo kugabanuka, gutunganya neza hamwe nibikoresho byiza bya mashini.
Byongeye kandi, igisubizo kirimo 40% nyuma y’ibicuruzwa byakoreshejwe nyuma y’ibicuruzwa, bishobora gukoreshwa mu gice cyo hagati cy’amafirime agabanuka, bishobora kugabanya neza imyuka ihumanya ikirere ndetse n’ingufu zikoreshwa mu gihe cyo gutunganya resin kandi bikagera ku ntego yo gutunganya firime.
Kuva mu mwaka wa 2019, hatangijwe igisubizo ku isi hose ku byangiza umwanda wa pulasitike, kandi amasosiyete akoresha plastike yiyemeje kwagura ku buryo bugaragara ikoreshwa rya plastiki itunganijwe neza cyangwa ngo yanduze plastike yakoreshejwe.Intego yashyizweho na Circular Plastics Alliance ni ukongera umubare wa plastiki itunganijwe neza ku isoko ry’ubumwe bw’ibihugu by’Uburayi ukagera kuri toni miliyoni 10 za metero mu mwaka wa 2025. Ibihangange bya peteroli nka Dow, Total Borealis, INEOS, SABIC, Eastman, na Covestro byose bigenda bitera intambwe nini mu nganda za plastiki zongeye gukoreshwa.
——Japan Nagase yatangije PET ya chimique ikoreshwa na tekinoroji ya PCR
PCR nyinshi kumasoko nizitunganyirizwa kumubiri, ariko gutunganya umubiri bifite intege nke, nko kugabanuka kwimiterere yimashini, kugabanya imikoreshereze yamabara, no kudashobora gutanga urwego rwibiryo.Ariko, hamwe niterambere ryikoranabuhanga, kugarura imiti PCR itanga amahitamo menshi kandi meza kumasoko, cyane cyane kumasoko yo murwego rwohejuru.
Ibyiza byo gutunganya imiti PCR irimo: ubuziranenge bumwe nibiranga ibikoresho byumwimerere;ibintu bifatika;ntibikenewe kubumba n'imashini;guhindura ibipimo, gukoresha mu buryo butaziguye;ibara rihuye na porogaramu;Irashobora kubahiriza REACH, RoHS, EPEAT ibipimo;gutanga ibicuruzwa byo mu rwego rwibiryo, nibindi
—— Gupakira ibintu byose byuzuye byo kwita kumisatsi ku isoko rya L'Oreal Ubushinwa bikozwe muri plastiki ya PCR 100%
Itsinda rya L'Oréal ryasabye igisekuru gishya intego z’iterambere rirambye 2030 "L'O éal ejo hazaza", iyi ntego y’intego ishingiye ku nkingi eshatu: kwihindura ku bijyanye n'imbibi z'isi;kongerera ubushobozi urusobe rw'ibidukikije;Tanga umusanzu wo gukora "moteri-ebyiri" yihutisha impinduka imbere kandi igaha urusobe rwibinyabuzima hanze.
L'Oreal yatanze amategeko arindwi yo kugabanya ibyuka bihumanya ikirere kuri buri gicuruzwa 50% muri 2030 ugereranije na 2016;muri 2025, ibikoresho byose bizakora bizamura ingufu zingufu, bikoreshe ingufu zisubirwamo 100%, hanyuma bigere kubutabogamye bwa karubone;Kugeza 2030, binyuze mu guhanga udushya, abaguzi bazagabanya gaze ya parike iterwa no gukoresha ibicuruzwa byacu 25% kuri buri gice cyibicuruzwa byarangiye ugereranije na 2016;muri 2030, 100% byamazi mubikorwa byinganda bizongera gukoreshwa Koresha;muri 2030, 95% byibigize mubitegura bizaba bishingiye kuri bio, biva mumabuye y'agaciro menshi cyangwa gutunganya ibicuruzwa;muri 2030, 100% bya plastike mubipfunyika byibicuruzwa bizakomoka mubikoresho bitunganijwe neza cyangwa bishingiye kuri bio (kugeza muri 2025, 50% bizagerwaho).
Mubyukuri, ibikorwa bijyanye "kubahiriza imipaka yisi" bimaze gushyirwa mubikorwa.Urebye ku isoko ry’Ubushinwa, gupakira ibintu bya L'Oreal Paris byita ku musatsi bimaze gukorwa muri plastiki ya PCR 100%;mubyongeyeho, L'Oreal yahinduye udushya two gupakira, ikoresheje uburyo bwo kuzuza cyangwa kwishyuza kugirango wirinde gupakira rimwe.
Twabibutsa ko, usibye ibicuruzwa bya L'Oreal byapakiye ibicuruzwa, itsinda ryanyujije kuri iki cyerekezo cyo gupakira ibidukikije ku zindi nzira.Ibikoresho bishya byo gupakira ibikoresho bya "green pack" byatangijwe kubufatanye na Tmall ni urugero rwingenzi.Mu Gushyingo 2018, iryo tsinda ryakoranye na Tmall gushyira ahagaragara uburyo bushya bwo gupakira ibikoresho byitwa "icyatsi kibisi" ku bicuruzwa byacyo byiza;muri 2019, L'Oreal yaguye "icyatsi kibisi" ku bicuruzwa byinshi, hamwe na miliyoni 20 zose zoherejwe A "icyatsi kibisi".
Ibicuruzwa bitandukanye bya PCR bya Somewang nibyerekanwe.
Reka tugire uruhare mu kurengera ibidukikije hamwe.Ibicuruzwa byinshi bya PCR, kuriinquiry@somewang.com
