ʻO ka Polyurethane kekahi o nā mea i hoʻohana nui ʻia ma ka honua, akā ʻike pinepine ʻia i ko mākou ola i kēlā me kēia lā. Akā inā ʻoe ma ka home, i ka hana a i kāu kaʻa paha, ʻaʻole mamao loa ia, me ka hoʻohana maʻamau mai nā moena a me nā mea e hoʻopili ai i ke kūkulu hale, nā ʻāpana kaʻa a me nā wāwae o nā kāmaʻa.

Akā e like me nā plastics ʻē aʻe i hele nui ʻole ʻia, ka hoʻohana nui ʻana opolyurethaneke hoʻopuka nei i nā hopohopo e pili ana i kona hopena kaiapuni. No ka hoʻomaopopo maikaʻi ʻana i nā manawa kūpono no ka hoʻihoʻi ʻana i ka polyurethane no ka hana hou ʻana a no ka hoʻololi ʻana i nā kemika i hoʻohana ʻia i kāna hana ʻana me nā mea kanu ʻē aʻe, ua hui pū nā mea noiʻi mai ka US Department of Energy's (DOE) Argonne National Laboratory, Northwestern University a me The Dow Chemical Company e alakaʻi. ka loiloi piha mua o "Material Flows of Polyurethane in the United States."
