Ko te Polyurethane tetahi o nga rawa kirihou e whakamahia nuitia ana i te ao, engari ka warewarehia i roto i o tatou oranga o ia ra.Heoi ahakoa kei te kainga koe, kei te mahi, kei roto ranei i to waka, kaore i te matara atu, he maha nga whakamahinga mutunga mai i nga mokete me te urunga taonga ki te whakamaarama whare, nga waahanga motuka me nga kapu hu.

Engari ka rite ki etahi atu kirihou e kore e hangaruatia, te whakamahi whanuipolyurethanekei te whakaputa i nga awangawanga e pa ana ki te paanga o te taiao.Kia pai ake ai te mohio ki nga whai waahi ki te whakaora i te polyurethane mo te hangarua me te whakakapi i nga matū e whakamahia ana i roto i tana mahi ki nga momo tipu, i hono tahi nga kairangahau mai i te US Department of Energy's (DOE) Argonne National Laboratory, Northwestern University me The Dow Chemical Company ki te whakahaere. te aromatawai matawhānui tuatahi o “Material Rere o Polyurethane i te United States.”Ko te rangahau i whakaputaina tata nei i roto i te hautakaPūtaiao Taiao me te Hangarau.

"Ko te whainga ko te maarama he pehea te raina me te porohita o te whakamahi i nga polyurethanes i Amerika," ta Jennifer Dunn te kaituhi-kaituhi, ko ia te kaiwhakahaere tuarua o Northwestern's Center for Engineering Sustainability and Resilience me tetahi mema o te Papatono on Plastics. , Ecosystems and Public Health i te Institute for Sustainability and Energy at Northwestern (ISEN)."I hiahia ano matou ki te kite mena he waahi ki te whakarei ake i te porowhita me te whakanui ake i te ihirangi koiora o te polyurethanes."

Ko te ohanga raina tetahi e whakamahia ai nga rawa mata hei hanga hua katahi ka maka atu i te mutunga o to ratau oranga.I roto i te ohanga porohita, ka whakahokia mai aua rawa, ka whakamahia ano.Ka whakawhäitihia te hiahia ki te tango i etahi atu rauemi taiao, penei i te kora matatoka, me te whakaiti i te nui o nga para ka tukuna ki nga waahi whenua.

I kii a Dunn, he ahorangi tuarua mo te hangarau matū me te hangarau koiora i te Northwestern's McCormick School of Engineering, ahakoa i tumanako nga kairangahau ki te kimi i tetahi punaha raina mo te polyurethanes, "ma te kite mai i te tirohanga rerenga rauemi, mai i nga rauemi timatanga ki te mutunga. o te ora, he maamaa noa."

E ai ki te kaituhi a Troy Hawkins, te kaiarahi i te Roopu Fuels and Products i Argonne's Systems Assessment Center, i kitea e te rangahau he maha nga uaua e pa ana ki te pehea me te wa e taea ai te whakaora me te hangarua nga polyurethanes.
