I-polyurethane ingenye yezinto zepulasitiki ezisetshenziswa kakhulu emhlabeni, kodwa ngokuvamile azinakwa ezimpilweni zethu zansuku zonke. Nokho kungakhathaliseki ukuthi usekhaya, emsebenzini noma emotweni yakho, ngokuvamile ayikude, kanye nokusetshenziswa okujwayelekile okusukela kumatilasi nefenisha yokunamathisela izinto zokwakha, izingxenye zemoto ngisho namathe ezicathulo.

Kepha njengamanye amapulasitiki ahamba kakhulu engasasebenzi kabusha, ukusetshenziswa okwandile kwei-polyurethaneidala ukukhathazeka ngomthelela wayo kwezemvelo. Ukuze kuqondwe kangcono amathuba okubuyisela i-polyurethane ukuze igaywe kabusha futhi ithathelwe indawo amakhemikhali asetshenziswa ekukhiqizweni kwawo ngezinye izindlela ezisekelwe ezitshalweni, abacwaningi boMnyango Wezamandla wase-US (DOE) Argonne National Laboratory, Northwestern University kanye neDow Chemical Company bahlanganyele ndawonye ukuze benze ukuhlola kokuqala okuphelele “Kwezinto Ezisetshenziswayo Ze-Polyurethane e-United States.” Ucwaningo lusanda kushicilelwa kujenaliIsayensi Yezemvelo Nobuchwepheshe.

"Inhloso bekuwukuqonda ukuthi ukusebenzisa kwethu i-polyurethanes kuyindilinga kanjani e-United States," kuchaza umbhali ohlanganyele uJennifer Dunn, ongumqondisi ohlangene weNorthwestern's Center for Engineering Sustainability and Resilience futhi oyilungu loHlelo Lwepulasitiki, Imvelo kanye Nezempilo Yomphakathi e-Institute for Sustainability and Energy at Northwestern (ISEN). "Besifuna futhi ukubona ukuthi akhona yini amathuba okuthuthukisa i-circularity kanye nokwandisa okuqukethwe kwe-bio-based polyurethanes."

Umnotho oqondile yilowo lapho kusetshenziswa izinto ezingavuthiwe ukwenza imikhiqizo bese zilahlwa ekugcineni kwezimpilo zabo. Emnothweni oyindilinga, lezo zinto ezifanayo ziyatholwa futhi ziphinde zisetshenziswe. Lokhu kunciphisa isidingo sokukhipha izinsiza zemvelo ezengeziwe, njengamafutha ezinto ezimbiwa phansi, kuyilapho kunciphisa inani lemfucuza ethunyelwa ezindaweni zokulahla imfucuza.

UDunn, ophinde abe nguprofesa osebenzisana naye wobunjiniyela bamakhemikhali nebhayoloji eMcCormick School of Engineering, eNorthwestern's McCormick School, uthe nakuba abacwaningi bekulindeleke ukuthi bathole uhlelo oluqondile lwama-polyurethanes, "belubona ngombono wokugeleza kwezinto, kusukela ezintweni zokuqala kuya ekupheleni kwempilo, belugqame ngokusobala."

Ngokusho kombhali osebenzisana naye u-Troy Hawkins, ohola i-Fuels and Products Group e-Argonne's Systems Assessment Center, lolu cwaningo lugqamise inani lezinto eziyinkimbinkimbi ezithinta indlela futhi nini i-polyurethanes ingatholakala futhi isetshenziswe kabusha.
