Qhov Kev Sib Tw Ntawm Cov Nqi Siv Rov Qab Tsawg: Raws li lub ntiaj teb thib rau - hom yas loj tshaj plaws, polyurethane tau raug kev txom nyem ntev los ntawm kev rov ua dua tshiab ntawm tsawg dua 30%. Nws txoj kev sib txuas, kev sib txuas ntawm cov qauv sib txuas ua rau nws yooj yim rau yooj yim yaj thiab rov zoo li cov thermoplastics, uas ua rau cov khib nyiab loj heev thaum kawg raug xa mus rau qhov chaw pov tseg lossis cov chaw tua hluav taws.
Tshuaj Recycling raws li qhov tseem ceeb Breakthrough: Tsis zoo li lub cev sib tsoo- uas txwv cov khoom siv rau "downcycling"- cov txheej txheem siv tshuaj (xws li glycolysis thiab alcoholysis) tuaj yeem rhuav tshem cov khoom pov tseg polyurethane rau hauv siab - cov khoom muaj nqis xws li polyols, ua rau "upcycling." Qhov no yog txoj hauv kev tseem ceeb rau kev lag luam kom ua tiav kaw -loop ntsuab ntau lawm thiab hauv paus daws teeb meem ib puag ncig.
Hloov Kev Xav Tau Tsav Tsheb: Lub hom phiaj ntawm kev lag luam kev loj hlob tau hloov los ntawm cov kev lag luam ib txwm muaj xws li kev tsim cov rwb thaiv tsev thiab cov rooj tog zaum mus rau cov chaw tawm tshiab xws li lub zog tshiab tsheb (nrog qhov kev thov loj hlob ntawm kwv yees li 17%) thiab hluav taws xob. Cov ntawv thov tshiab, suav nrog cov khoom siv tsheb sib sib zog nqus thiab formaldehyde-dawb engineered ntoo, kuj tseem nthuav dav kev lag luam.
Los ntawm Scaling Up To Strengthening: Thaum muaj kev sib tw sib tw, kev pom zoo ntawm kev lag luam yog kom txav deb ntawm qhov qis -qhov kawg muaj peev xwm nthuav dav thiab nqi kev tsov kev rog, tsom mus rau qhov siab - tus nqi- ntxiv cov ntu kev lag luam thiab siab - kawg daim ntawv thov. Piv txwv suav nrog kev tsim kho siab -kev ua tau zoo polyurethane sib xyaw rau cov cua turbine hniav thiab cov chaw tsim khoom hauv hiav txwv kom coj mus rau hauv "xiav dej hiav txwv" tshiab txoj hauv kev loj hlob.
