I-Polyurethane yenye yezona zinto zisetyenziswa kakhulu kwiplastiki yeplastiki, kodwa ihlala ingahoywa kubomi bethu bemihla ngemihla.Nangona usekhaya, emsebenzini okanye kwisithuthi sakho, ihlala ingekho kude, kunye nosetyenziso oluqhelekileyo olususela koomandlalo kunye nefenitshala ekhuniweyo ukuya kwi-insulation yokwakha, iinxalenye zemoto kunye neepali zezihlangu.

Kodwa njengezinye iiplastiki ezihamba kakhulu zingasetyenziswanga, ukusetyenziswa okuxhaphakileyo kwei-polyurethaneidala inkxalabo malunga nefuthe layo kokusingqongileyo.Ukuqonda ngcono amathuba okufumana kwakhona i-polyurethane ukuze isetyenziswe ngokutsha kunye nokutshintsha iikhemikhali ezisetyenzisiweyo kwimveliso yayo nezinye ezisekelwe kwizityalo, abaphandi abavela kwiSebe lezaMandla lase-US (DOE) i-Argonne National Laboratory, iYunivesithi yaseNorthwestern kunye neDow Chemical Company badityanisiwe ukuze baqhube. Uvavanyo lokuqala olubanzi lwe "Material Flows of Polyurethane eUnited States."Uphononongo lusanda kupapashwa kwijenaliInzululwazi ngezokusiNgqongileyo kunye neTekhnoloji.

“Injongo ibikukuqonda indlela ehambelana ngayo nesetyhula ukusebenzisa kwethu i-polyurethanes e-United States,” ucacise watsho umbhali-mbhali uJennifer Dunn, ongumalathisi weZiko laseMntla-ntshona leZiko lobuNjineli bokuZinzisa kunye nokuZinzisa kunye nelungu leNkqubo yePlastiki. , I-Ecosystems kunye neMpilo yoLuntu kwiZiko lokuZinza kunye namandla eMntla-ntshona (ISEN)."Sikwafuna ukubona ukuba akhona na amathuba okuphucula ukujikeleza kunye nokunyusa umxholo we-bio-based polyurethanes."

Uqoqosho oluhambelanayo lolo apho kusetyenziswa izinto ezikrwada ukwenza iimveliso kwaye emva koko balahlwe kude ekupheleni kobomi babo.Kuqoqosho lwesetyhula, ezo zixhobo zifanayo zifunyanwa kwaye ziphinda zisetyenziswe.Oku kunciphisa imfuno yokukhupha imithombo yendalo eyongezelelweyo, njengamafutha efosili, ngelixa kuncitshiswa inani lenkunkuma ethunyelwa kwiindawo zokulahla inkunkuma.

UDunn, okwangunjingalwazi onxulumene nobunjineli beekhemikhali kunye nobunjineli bebhayoloji kwiMcCormick School of Engineering, uthe ngelixa abaphandi bebelindele ukufumana inkqubo enkulu ye-polyurethanes, "ukuyibona ngombono wokuhamba kwezinto, ukusuka kwizixhobo zokuqala ukuya esiphelweni. ubomi, yayiyinto nje ecacileyo.”

Ngokutsho kombhali-mbhali uTroy Hawkins, okhokela i-Fuels and Products Group kwi-Argonne's Systems Assessment Centre, uphando lubonise inani lezinto ezinzima ezichaphazela indlela kwaye nini i-polyurethanes inokufunyanwa ngayo kwaye isetyenziswe kwakhona.
