Ua ntej tshaj plaws, lub Michelin nws tsis xav ua cov log tsheb tsuas yog los ntawm cov yas rov ua dua tshiab. Yas, thiab hauv qhov tshwj xeeb no, kev siv PET (polyethylene terephthalate), thermoplastic polymer siv ntau niaj hnub no (los ntawm khaub ncaws mus rau lub fwj dej thiab dej qab zib), tsuas yog ib qho ntawm ntau cov khoom xyaw uas ua rau lub log tsheb - ntau dua 200. raws li Michelin.
Peb feem ntau hais tias lub log tsheb yog ua los ntawm roj hmab, tab sis qhov tseeb nws tsis zoo li ntawd. Lub log tsheb tsis yog tsuas yog ua los ntawm cov roj hmab ntuj, tab sis kuj yog cov roj hmab hluavtaws, hlau, cov ntaub ntawv textile (synthetic), ntau yam polymers, carbon, additives, thiab lwm yam.
Kev sib xyaw ntawm cov khoom, tsis yog txhua yam ntawm lawv yooj yim rov ua dua lossis rov siv dua, ua rau ib puag ncig cuam tshuam ntawm cov log tsheb siab - thiab thaum lawv siv - ua rau Michelin mus nrhiav lub hom phiaj kom muaj 100% cov log tsheb ruaj khov los ntawm 2050 (ib feem ntawm kev lag luam ncig), piv txwv li. tsuas yog siv cov khoom siv rov ua dua tshiab thiab siv dua tshiab hauv nws cov khoom tsim, nrog rau lub hom phiaj nruab nrab ntawm 40% ntawm cov khoom siv hauv nws cov log tsheb kom ruaj khov los ntawm 2030.
Recycled PET
PET tau siv niaj hnub no los ntawm Michelin thiab lwm cov tuam txhab fiber ntau hauv kev tsim cov log tsheb, ntawm tus nqi ntawm 800 txhiab tons hauv ib xyoos (tag nrho rau kev lag luam), qhov sib npaug ntawm 1.6 billion log tsheb tsim.
Txawm li cas los xij, kev rov ua dua tshiab ntawm PET, txawm tias ua tau los ntawm thermomechanical txhais tau tias, tau ua rau cov khoom siv rov ua dua tshiab uas tsis tau lees tias cov khoom zoo ib yam li PET nkauj xwb, yog li nws tsis rov nkag mus rau cov log tsheb ntau lawm. Nws yog nyob rau ntawm lub sijhawm no uas ib kauj ruam tseem ceeb tau ua rau kev ua tiav lub log tsheb ruaj khov thiab qhov no yog qhov uas Carbios tuaj txog.
Carbios yog ib tug pioneer nyob rau hauv bioindustrial kev daws teeb meem uas xav kom reinvent lub neej voj voog ntawm yas thiab textile polymers. Ua li no, nws siv cov tshuab enzymatic recycling ntawm PET yas pov tseg. Cov kev sim ua los ntawm Michelin ua rau nws muaj peev xwm ua tau zoo Carbios 'rov siv PET, uas yuav tso cai rau nws siv los tsim cov log tsheb.
Carbios 'cov txheej txheem siv cov enzyme uas muaj peev xwm depolymerizing tus tsiaj (muaj nyob rau hauv lub raj mis, tais, polyester khaub ncaws), decomposing nws mus rau hauv nws cov monomers (cov ntsiab lus uas tau rov qab nyob rau hauv lub polymer) uas tom qab dhau los ntawm nws dua ib tug txheej txheem polymerization tso cai rau cov khoom. yuav tsum tau ua los ntawm 100% recycled thiab 100% recyclable PET yas nrog zoo tib yam li yog hais tias lawv tau raug tsim nrog nkauj xwb PET - raws li Carbios, nws cov txheej txheem tso cai rau infinite recycling.
Hauv lwm lo lus, Carbio's recycled PET, kuaj los ntawm Michelin, tau txais tib lub zog zoo uas xav tau rau kev tsim nws cov log tsheb.
Kev ua ntej uas tsis tsuas yog tso cai rau Michelin kom ncav cuag nws lub hom phiaj ntawm kev tsim cov log tsheb ruaj khov, tab sis tseem yuav tso cai rau txo qis kev tsim cov PET nkauj xwb, roj av (zoo li txhua yam yas) - raws li Michelin cov kev suav, kev rov ua dua ntawm kev xyaum peb billion. PET fwj tso cai rau koj kom tau txais tag nrho cov fibers uas koj xav tau.
