Polyurethane ndeimwe yeanonyanya kushandiswa pasi rose epurasitiki zvinhu, asi inowanzo furatirwa muhupenyu hwedu hwezuva nezuva.Asi kunyangwe iwe uri kumba, kubasa kana mumotokari yako, kazhinji hakusi kure, nekushandiswa kwakajairwa kubva kumamatiresi uye fenicha cushioning kusvika pakuvharisa zvivakwa, zvikamu zvemotokari uye kunyange pasi peshangu.

Asi semamwe mapurasitiki anoenda zvakanyanya asina kushandiswa, kushandiswa kwakapararira kwepolyurethaneiri kuunza kushushikana pamusoro pekukanganisa kwayo kwezvakatipoteredza.Kuti tinzwisise zviri nani mikana yekudzoreredza polyurethane yekudzokorodza uye yekutsiva makemikari anoshandiswa mukugadzirwa kwayo nezvinomera-zvinomera, vaongorori kubva kuUS Department of Energy's (DOE) Argonne National Laboratory, Northwestern University neThe Dow Chemical Company vakabatana kuti vaite. yekutanga kuongororwa kwakazara kwe "Material Flows yePolyurethane muUnited States."Chidzidzo ichi chakabudiswa munguva pfupi yapfuura mujenariEnvironmental Science & Technology.

"Chinangwa chaive chekunzwisisa kuti mutsara unopesana sei nemashandisiro atinoita polyurethanes muUnited States," akatsanangura mumwe munyori Jennifer Dunn, anove director director weNorthwestern's Center for Engineering Sustainability uye Resilience uye nhengo yeChirongwa chePlastiki. , Ecosystems uye Hutano Hwevanhu paInstitute for Sustainability uye Energy kuNorthwestern (ISEN)."Taidawo kuona kana paine mikana yekusimudzira kutenderera uye kuwedzera bio-based content ye polyurethanes."
