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 ngeendlela ezizezinye ezisekwe kwizityalo, abaphandi abasuka kwiSebe lezaMandla lase-US (DOE) i-Argonne National Laboratory, iYunivesithi yaseNorthwestern kunye neDow Chemical Company badityaniswe kunye ukwenza uvavanyo lokuqala olubanzi "lokuMququza kwezinto zePolyurethane eUnited States." Uphononongo lusanda kupapashwa kwijenaliInzululwazi ngezokusiNgqongileyo kunye neTekhnoloji.

"Injongo yayikukuqonda indlela ehambelana ngayo nesetyhula ukusetyenziswa kwethu kwe-polyurethanes e-United States," kuchaza umbhali-mbhali uJennifer Dunn, ongumlawuli odibeneyo weZiko leMntla-ntshona yeZiko lobuNjineli bokuZinzisa kunye nokuQiniseka kunye nelungu leNkqubo yePlastiki, i-Ecosystems kunye neMpilo yoLuntu kwiZiko lokuZinza kunye namandla eNyakatho-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 imfuneko yokukhupha imithombo yendalo eyongezelelweyo, njengamafutha efosili, ngelixa kuncitshiswa inani lenkunkuma ethunyelwa kwiindawo zokulahla inkunkuma.

UDunn, okwangunjingalwazi onxulumene nobunjineli bemichiza kunye nebhayoloji kwiMcCormick School of Engineering, uthe ngelixa abaphandi bebelindele ukufumana inkqubo enkulu ye-polyurethanes, "beyibona ngombono wokuhamba kwemathiriyeli, ukusuka kwizixhobo zokuqala ukuya esiphelweni sobomi, ibiyimigca 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.
