Choyamba, ndi Michelin safuna kupanga matayala okha ndi pulasitiki zobwezerezedwanso. Pulasitiki, ndipo pankhani iyi, kugwiritsa ntchito PET (polyethylene terephthalate), polima ya thermoplastic yomwe imagwiritsidwa ntchito kwambiri masiku ano (kuchokera ku zovala kupita ku mabotolo amadzi ndi zakumwa zozizilitsa kukhosi), ndi chimodzi mwazinthu zambiri zomwe zimapanga tayala - zambiri 200 malinga ndi Michelin.
Nthawi zambiri timati tayala ndi labala, koma zoona zake sizili choncho. Tayala silimangopangidwa ndi mphira wachilengedwe, komanso mphira wopangira, chitsulo, nsalu (zopanga), ma polima osiyanasiyana, kaboni, zowonjezera, ndi zina zambiri.
Kusakanikirana kwazinthu, zomwe siziri zonse zomwe zimatha kubwezeretsedwanso kapena kugwiritsidwanso ntchito, kumapangitsa kuti matayala awonongeke kwambiri - komanso panthawi yomwe amagwiritsidwa ntchito - kutsogolera Michelin kukwaniritsa cholinga chokhala ndi 100% matayala okhazikika pofika chaka cha 2050 (gawo la chuma chozungulira), mwachitsanzo. kugwiritsa ntchito zinthu zongowonjezedwanso komanso zobwezerezedwanso popanga, ndi chandamale chapakati cha 40% yazinthu zomwe zimagwiritsidwa ntchito m'matayala ake kukhala okhazikika pofika 2030.
zobwezerezedwanso PET
PET imagwiritsidwa ntchito kale masiku ano ndi Michelin ndi ena opanga ma fiber popanga matayala, pamlingo wa matani 800,000 pachaka (chiwerengero chamakampani), chofanana ndi matayala 1.6 biliyoni opangidwa.
Komabe, kubwezeretsanso kwa PET, ngakhale kuti kunali kotheka ndi njira za thermomechanical, kunapangitsa kuti zinthu zobwezerezedwanso zomwe sizinatsimikizire zamtundu womwewo wa namwali PET, kotero sizinalowenso mumayendedwe opangira matayala. Apa ndipamene gawo lofunikira lachitika kuti tipeze tayala lokhazikika ndipo apa ndipamene Carbios imalowa.
Carbios ndi mpainiya mu mayankho a bioindustrial omwe akufuna kubwezeretsanso moyo wa ma polima apulasitiki ndi nsalu. Kuti achite izi, amagwiritsa ntchito ukadaulo wa enzymatic wobwezeretsanso zinyalala zapulasitiki za PET. Mayesero opangidwa ndi Michelin adapangitsa kuti zitsimikizire kuti Carbios 'recycled PET PET, yomwe ingalole kuti igwiritsidwe ntchito popanga matayala.
Njira ya Carbios imagwiritsa ntchito puloteni yomwe imatha kuwononga PET (yomwe ili m'mabotolo, ma tray, zovala za poliyesitala), ndikuyiyika kukhala ma monomers ake (zinthu zomwe zimabwerezedwanso mu polima) zomwe pambuyo podutsamonso njira yopangira polymerization imalola zinthu. kuti ipangidwe ndi 100% yopangidwanso ndi 100% yobwezeretsanso pulasitiki ya PET yokhala ndi khalidwe lomwelo ngati kuti anapangidwa ndi namwali PET - malinga ndi Carbios, njira zake zimalola kukonzanso kosatha.
Mwanjira ina, Carbio's recycled PET, yoyesedwa ndi Michelin, idapeza mikhalidwe yokhazikika yofunikira popanga matayala ake.
Kupita patsogolo komwe sikungolola Michelin kuti akwaniritse cholinga chake chopanga matayala okhazikika, komanso kumathandizira kuchepetsa kupanga kwa namwali PET, mafuta opangidwa ndi mafuta (monga mapulasitiki onse) - malinga ndi kuwerengera kwa Michelin, kubwezeretsanso kwa pafupifupi mabiliyoni atatu. Mabotolo a PET amakulolani kuti mupeze ulusi wonse womwe mukufuna.
