Polyurethane ni kimwe mu bikoresho bya pulasitiki bikoreshwa cyane ku isi, ariko akenshi birengagizwa mu mibereho yacu ya buri munsi. Nyamara waba uri murugo, kukazi cyangwa mumodoka yawe, mubisanzwe ntabwo ari kure, hamwe nibisanzwe bikoreshwa kuva kuri matelas hamwe no kwisiga ibikoresho byo mu nzu kugeza kubaka inyubako, ibice by'imodoka ndetse n'inkweto.

Ariko kimwe nizindi plastiki zigenda ahanini zidakoreshwa, ikoreshwa ryinshipolyurethaneni ugutera impungenge kubyerekeye ingaruka z’ibidukikije. Kugira ngo dusobanukirwe neza amahirwe yo kugarura polyurethane yo gutunganya no gusimbuza imiti ikoreshwa mu musaruro wayo n’ubundi buryo bushingiye ku bimera, abashakashatsi bo muri Minisiteri y’ingufu muri Amerika (DOE) muri Laboratwari y’igihugu ya Argonne, muri kaminuza y’Amajyaruguru y’Uburengerazuba hamwe n’isosiyete ikora imiti ya Dow bifatanije gukora isuzuma ryambere ryuzuye ryerekeye “Ibikoresho bitemba bya Polyurethane muri Amerika.” Ubushakashatsi buherutse gusohoka mu kinyamakuruUbumenyi bwibidukikije & Ikoranabuhanga.

Jennifer Dunn, umuyobozi wungirije w'ikigo cy’amajyaruguru gishinzwe uburinganire bw’imyubakire n’imyororokere, akaba n'umwe mu bagize gahunda ishinzwe plastike, urusobe rw’ibinyabuzima n’ubuzima rusange mu kigo cy’amajyambere n’ingufu mu majyaruguru y’iburengerazuba (ISEN) yabisobanuye agira ati: “Icyari kigamijwe kwari ukumva uburyo umurongo ugereranije n’uburyo tuzenguruka dukoresha polyurethanes muri Amerika.” Ati: “Twifuzaga kandi kureba niba hari amahirwe yo kuzamura uruziga no kongera ibinyabuzima bishingiye kuri bio ya polyurethanes.”

Ubukungu buringaniye ni bumwe mubikoresho bikoreshwa mugukora ibicuruzwa hanyuma bikajugunywa nyuma yubuzima bwabo. Mu bukungu buzenguruka, ibyo bikoresho biragarurwa kandi bigakoreshwa. Ibi bigabanya gukenera kongera umutungo kamere, nkibicanwa bya fosile, mugihe bigabanya imyanda yoherejwe mumyanda.

Dunn, na we wungirije umwarimu w’ubuhanga bw’ibinyabuzima n’ibinyabuzima mu Ishuri ry’Ubwubatsi rya McCormick ry’Amajyaruguru y’Uburengerazuba, yavuze ko mu gihe abashakashatsi bari biteze ko bazabona uburyo bunini bw’umurongo wa polyurethanes, “kubibona binyuze mu bikoresho bigenda neza, uhereye ku bikoresho byatangiye kugeza ku iherezo ry’ubuzima, byari umurongo ugaragara.”

Nk’uko byatangajwe n’umwanditsi witwa Troy Hawkins uyobora itsinda ry’ibicanwa n’ibicuruzwa mu kigo cya Argonne's Systems Assessment Centre, ubushakashatsi bwerekanye ibintu byinshi bigoye bigira ingaruka ku gihe n’igihe polyurethanes ishobora kugarurwa no kuyitunganya.
