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 nedzimwe nzira dzekudyara, vaongorori kubva kuUS Department of Energy's (DOE) Argonne National Laboratory, Northwestern University neThe Dow Chemical Company vakabatana kuita ongororo yekutanga yakazara ye "Material Flows of Polyurethane muUnited States." Chidzidzo ichi chakabudiswa munguva pfupi yapfuura mujenariEnvironmental Science & Technology.

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

Upfumi hwemutsara ndeuyo umo zvigadzirwa zvinoshandiswa kugadzira zvigadzirwa uye zvino zvinozoraswa pakupera kwehupenyu hwavo. Muhupfumi hwedenderedzwa, izvo zvinhu zvakafanana zvinodzoserwa uye kushandiswa zvakare. Izvi zvinodzikamisa kudiwa kwekubvisa zvimwe zviwanikwa, semafuta efossil, uku uchidzikisa huwandu hwemarara anotumirwa kunoraswa.

Dunn, anove zvakare purofesa anoshamwaridzana wemakemikari uye biological engineering kuNorthwestern McCormick Chikoro cheUinjiniya, akataura kuti nepo vaongorori vaitarisira kuwana yakanyanya mutsara sisitimu ye polyurethanes, "vachiiona kuburikidza neyekuyerera kwezvinhu, kubva kune yekutanga zvinhu kusvika kumagumo ehupenyu, yaingove mutsara."

Sekureva kwemunyori pamwe chete Troy Hawkins, anotungamira Fuels uye Zvigadzirwa Boka muArgonne's Systems Assessment Center, chidzidzo ichi chakaratidza huwandu hwakaoma hunokanganisa kuti uye riini polyurethanes inogona kudzoserwa uye kushandiswazve.
