Kupambana kwaposachedwa kwaukadaulo woletsa moto wa polyurethane (PU) kukonzanso miyezo yachitetezo chazinthu m'mafakitale onse. Makampani aku China amatsogola ndi zovomerezeka zatsopano: Gulu la Jushi lidapanga PU yoyendetsedwa ndi madzi ya nano-SiO₂, ndikukwaniritsa index ya okosijeni ya 29% (kukana moto kwa Gulu A) kudzera mu mgwirizano wa phosphorous-nitrogen, pomwe Guangdong Yurong adapanga chotchinga chamoto chomwe chimalumikizana ndi ma molekyulu a PU, kuonetsetsa kuti chitetezo chikuyenda bwino. Kunming Zhezitao adaphatikizira ma phosphate-modified carbon fibers mu PU elastomers, kukulitsa kukhazikika kwamafuta komanso kupanga char pakuyaka.
Momwemonso, kafukufuku wapadziko lonse lapansi amapititsa patsogolo mayankho ogwirizana ndi chilengedwe. Kafukufuku wa 2025 ACS Sustainable Chemistry adawunikira machitidwe a phosphorous/silicon opanda halogen omwe nthawi imodzi amathandizira kukana lawi lamoto komanso anti-kudontha mu PU yamadzi. Mankhusu opangidwa ndi nano-silica opangidwa ndi mankhusu ophatikizana ndi osagwiritsa ntchito halogen retardants amalonjeza kukhazikika kwa thovu la PU, kukulitsa zotchinga zotentha popanda utsi wapoizoni.
Motsogozedwa ndi malamulo okhwima otetezedwa pamoto-monga EU REACH ndi California TB 117-msika wapulasitiki wosagwiritsa ntchito moto ukuyembekezeka kukwera kuchokera pa $ 3.5 biliyoni (2022) mpaka $ 5.2 biliyoni pofika 2030, pomwe Asia-Pacific ikulamulira 40% ya zofuna zapadziko lonse lapansi. Zatsopano zimayika patsogolo kusanja chitetezo, kulimba, komanso kukhudzidwa kwa chilengedwe, kuwonetsa kusintha kwa magawo a zomangamanga, zamagalimoto, ndi zamagetsi.
