Abstract:NeEuropean Green Deal, kukosha kwezvigadzirwa zvakadzokororwa uye zvinhu zvakawedzera.Kunyanya, kumabhodhoro ePET, yakakwira yezvinhu zvakadzokororwa zvinhu (rPET) inodiwa neindasitiri nevatengi.Chidzidzo ichi chakaitwa munharaunda yerabhu inodzokorora maitiro ehupenyu hwemaindasitiri, kuongorora zvingangoitika pamhando yerPET pamusoro pegumi nerimwe zvishwe zvekudzokorodza, nechinangwa chekushandisa huwandu hwakanyanya hwerPET uchidzokororwa.Kutenderera kwaisanganisira extrusion, solid state polycondensation (SSP), yechipiri extrusion kutevedzera kugadzirwa kwebhodhoro, kugeza inopisa uye nhanho yekuomesa.75% rPET uye 25% mhandara PET yakasimudzwa mumatenderedzwa gumi nerimwe kutevedzera kudzokorodza uye kugadzira maitiro.Samples dzakaitwa ongororo yemakemikari, yemuviri uye yebhayoloji.Hunhu hweiyo rPET zvinhu hauna kukanganiswa.Maparamita akadai seruvara, intrinsic viscosity, kusangana kwemakemikari akakosha uye kuvapo kwe mutagenic zvinosvibisa zvinogona kuongororwa zvakanaka.Hunhu hwezvinhu zvakagadzirwa hunogona kunge hwakakonzerwa neiyo yekupinza yemhando yepamusoro.Iyo yakavharwa loop PET bhodhoro recycling process uchishandisa rPET yemukati inosvika 75% yaigoneka pakutevera maitiro akarongwa, zvichiratidza kuti iyi nhanho yezvakadzokororwa zvemukati inogona kuchengetedzwa nekusingaperi pasina kukanganisa kunaka;
