Mbere ya byose ,. Michelin ntashaka gukora amapine gusa muri plastiki yongeye gukoreshwa. Plastike, kandi muriki gihe cyihariye, gukoresha PET (polyethylene terephthalate), polymer ya termoplastique ikoreshwa cyane muriyi minsi (kuva kumyenda kugeza kumacupa yamazi nibinyobwa bidasembuye), nikimwe mubintu byinshi bigize ipine - birenga 200 nk'uko byatangajwe na Michelin.
Mubisanzwe tuvuga ko ipine ikozwe muri reberi, ariko mubyukuri ntabwo aribyo. Ipine ntabwo ikozwe muri reberi karemano gusa, ahubwo ikora na reberi yubukorikori, ibyuma, ibikoresho byimyenda (synthique), polymers zitandukanye, karubone, inyongeramusaruro, nibindi.
Kuvanga ibicuruzwa, ntabwo byose byoroshye gukoreshwa cyangwa gukoreshwa, bituma ingaruka z’ibidukikije zipine cyane - no mugihe cyo kuyikoresha - bituma Michelin akurikirana intego yo kugira amapine arambye 100% muri 2050 (igice cyubukungu). ukoresheje gusa ibikoresho bishobora kuvugururwa no gutunganyirizwa mu musaruro wabyo, hamwe nintego yo hagati ya 40% yibikoresho bikoreshwa mumapine yayo biramba muri 2030.
PET
PET isanzwe ikoreshwa uyumunsi na Michelin hamwe nabandi bakora fibre mugukora amapine, ku gipimo cya toni ibihumbi 800 kumwaka (yose hamwe ninganda), ahwanye na miliyari 1.6 zakozwe.
Nyamara, gutunganya PET, nubwo byashobokaga hakoreshejwe uburyo bwa termo-mashini, byatumye habaho ibikoresho bitunganyirizwa ibintu bitemeza imitungo imwe n’isugi PET, bityo ntibyongera kwinjira murwego rwo gukora amapine. Aha niho hafashwe ingamba zikomeye zo kugera ku ipine rirambye kandi niho Carbios yinjira.
Carbios nintangarugero mubisubizo bya bioindustrial ishaka kuvugurura ubuzima bwubuzima bwa plastike n imyenda. Kubikora, ikoresha tekinoroji ya enzymatique yo gutunganya imyanda ya PET. Ibizamini byakozwe na Michelin byatumye bishoboka kwemeza Carbios 'yongeye gukoreshwa PET, izemerera kuyikoresha mu gukora amapine.
Inzira ya Carbios ikoresha enzyme ishoboye gutesha agaciro PET (ikubiyemo amacupa, tray, imyenda ya polyester), ikabora muri monomers (ibintu bisubirwamo muri polymer) iyo nyuma yo kuyinyuramo byongeye inzira ya polymerisation yemerera ibicuruzwa gukorwa muri 100% byongeye gukoreshwa hamwe na 100% byongeye gukoreshwa na PET ya plastike bifite ubuziranenge nkaho byakorewe hamwe na PET yisugi - nkuko Carbios ibivuga, inzira zayo zituma habaho gutunganya ibintu bitagira akagero.
Mu yandi magambo, Carbio yongeye gukoreshwa PET, yageragejwe na Michelin, yabonye imico imwe ikenewe kugirango ikore amapine yayo.
Iterambere ritemerera Michelin gusa kugera kuntego zayo zo gukora amapine arambye, ariko kandi rizafasha kugabanya umusaruro w’isugi PET, ishingiye kuri peteroli (nka plastiki zose) - ukurikije imibare ya Michelin, ikoreshwa rya miliyari eshatu Amacupa ya PET agufasha kubona fibre zose ukeneye.
