Marka hore, Michelin ma rabo inuu taayirro ka sameeyo balaastiig dib loo warshadeeyay oo keliya. Caaga, iyo kiiskan gaarka ah, isticmaalka PET (polyethylene terephthalate), polymer thermoplastic ah oo aad loo isticmaalo maalmahan (dharka ilaa dhalooyinka biyaha iyo cabitaannada fudud), waa mid ka mid ah maaddooyinka badan ee ka kooban taayirka - in ka badan 200 sida uu sheegay Michelin.
Caadi ahaan waxaynu nidhaahnaa in taayirka uu ka samaysan yahay caag, laakiin dhab ahaantii sidaas maaha. Taayirka ma aha oo kaliya ka samaysan caag dabiici ah, laakiin sidoo kale caag synthetic, birta, alaabta dharka (synthetic), polymers kala duwan, carbon, daro, iwm.
Isku darka alaabooyinka, dhammaantood maaha kuwo si fudud dib loo warshadeyn karo ama dib loo isticmaali karo, waxay ka dhigaysaa saameynta deegaanka ee taayirada mid sarreeya - sidoo kale inta lagu jiro isticmaalkooda - taasoo horseedaysa Michelin inay raacdo hadafka ah in 100% taayir waara 2050 (qayb ka mid ah wareegtada dhaqaalaha), ie. iyada oo la isticmaalayo kaliya agab dib loo cusboonaysiin karo oo dib loo warshadeeyey wax-soo-saarkeeda, iyada oo bartilmaameedka dhexe ee 40% ee agabka loo isticmaalo taayirkiisa uu yahay mid waara marka la gaadho 2030ka.
PET dib loo warshadeeyay
PET waxaa horeyba u isticmaalay maanta Michelin iyo soosaarayaasha kale ee fiber-ka soo saarista taayirada, oo ah heerka 800 kun oo tan sanadkii (wadarta guud ee warshadaha), oo u dhiganta 1.6 bilyan oo taayir ah oo la soo saaray.
Si kastaba ha ahaatee, dib-u-warshadaynta PET, inkasta oo ay suurtogal tahay hab-thermomechanical, waxay keentay walxo dib loo warshadeeyay oo aan dammaanad qaadin hanti la mid ah tan bikradaha PET, sidaas darteed dib uma gelin silsiladdii wax soo saarka taayirka. Waa wakhtigan in tallaabo muhiim ah loo qaaday sidii loo gaari lahaa taayir waara waana meesha uu ka soo galo Carbios.
Carbios waa hormuudka xalalka warshadaha bioindustrial kaas oo raba inuu dib u soo nooleeyo meertada nolosha ee caagagga iyo polymers-ka dunta. Si taas loo sameeyo, waxay isticmaashaa tignoolajiyada dib-u-warshadaynta enzymatic ee qashinka caagga ah ee PET. Tijaabooyin uu sameeyay Michelin ayaa suurtageliyay in la ansixiyo Carbios ee dib loo warshadeeyay PET, taas oo u oggolaan doonta isticmaalkeeda soo saarista taayirrada.
Habka Carbios 'wuxuu isticmaalaa enzim awood u leh inuu ka saaro PET (oo ku jira dhalooyin, saxaarad, dharka polyesterka), isaga oo u kala googooya monomers-kiisa (cutubyada ku soo noqnoqda polymer-ka) kaas oo ka dib marka uu mar kale marayo habka polymerization u ogolaanaya alaabta. in laga sameeyo 100% dib loo warshadeeyay iyo 100% dib loo warshadayn karo oo PET caag ah oo tayadeedu la mid tahay in lagu soo saaray bikrad PET - sida uu qabo Carbios, hababkeedu waxay ogol yihiin dib u warshadayn aan xad lahayn.
Si kale haddii loo dhigo, Carbio's PET ee dib loo warshadeeyay, oo ay tijaabisay Michelin, ayaa heshay tayada adkaysiga la mid ah ee looga baahan yahay soo saarista taayirkeeda.
Horudhac aan kaliya u oggolaan Michelin inuu si dhakhso ah u gaaro yoolka soo saarista taayirrada waara, laakiin sidoo kale wuxuu u oggolaanayaa inuu yareeyo wax soo saarka PET bikrad ah, batroolka ku saleysan (sida dhammaan balaastikada) - marka loo eego xisaabinta Michelin, dib-u-warshadaynta ku dhawaad saddex bilyan Dhalooyinka PET waxay kuu oggolaanayaan inaad hesho dhammaan fiilooyinka aad u baahan tahay.
