Eminyakeni yamuva nje, kube nokwanda okusheshayo kwezinto ezintsha ekucubunguleni ipulasitiki okushukumiswe yizinkinga zemvelo, izinguquko emithethweni, kanye nesidingo semakethe semikhiqizo eqhubekayo. Ukuqhubeka kobuchwepheshe bokugaywa kabusha, ukuthuthukiswa kwamapholima amasha, kanye nezinqubo ezintsha zokuguqula zishintsha indlela abakhiqizi abasondela ngayo ekwakhiweni, ukukhiqizwa, namasu okugcina impilo. Lezi zinguquko zithinta yonke imisebenzi ekuxhumaneni, kusukela kumsebenzi wokucubungula ipulasitiki esitolo kuya emaqenjini e-R&D ahlola izindlela zokukhiqiza ipulasitiki ngokungeziwe. Njengoba izinkampani zifuna ukubuyisana nezindleko, ukusebenza, nokuqhubeka, imboni ihamba ngohlelo oluhlanganisiwe oluhlanganisa ukugaywa kabusha ngomshini, ukutholwa kwamakhemikhali, nezixazululo ezisekelwe emvelweni. Lesi sethulo sichaza izihloko eziyinhloko ezilandelayo: ukugaywa kabusha okuthuthukisiwe, amakhemikhali amasha amapholima, imiklamo yemikhiqizo ye-circular-economy, kanye nezindlela zemvelo nezokushisa zokuphathwa kukadoti.

Izindlela zokucubungula ezintsha zinika amandla ukukhiqiza okukhulu nokusebenza okungcono kwezinto ngenkathi kuncishiswa ukusetshenziswa kwezinsiza kanye nokukhishwa. Ukubumba nge-extrusion kuhlala kubalulekile ekukhiqizeni okukhulu, kodwa kuthuthukiswa ngezinhlelo zokulawula ezihlakaniphile, izinzwa ezisebenza ngokuqondile, kanye nemiklamo ye-die eyenziwe ngezifiso ehambisana nokunciphisa udoti nokuthuthukisa ukungaguquguquki. Phakathi naleso sikhathi, ukukhiqizwa kwezinto zokupulasitiki ngezindlela zokwengeza kuyanda ngaphandle kokwenza amamodeli kuya ekukhiqizeni izingxenye ezincane, eziyinkimbinkimbi ezinciphisa ukusetshenziswa kwezinto nezigaba zokuhlanganisa. Izakhiwo zepulasitiki ze-thermosetting nazo ziyabuyekezwa: abakhiqizi manje baklama izinhlelo ezingalungiswa kalula noma zicubungulwe kabusha ngamakhemikhali, zixazulula imikhawulo yangaphambili ekusingatheni ukuphela kwempilo. Lezi zinguquko zobuchwepheshe zidinga ukuthuthukiswa kwamakhono abasebenzi kanye nonjiniyela bezenqubo kanye nokucatshangelwa kabusha kwezindlela zokugcinwa kanye nokuqinisekiswa kwekhwalithi ukuze kuzuze ngokugcwele izinzuzo zokuzinza.
