Chidule:Ndi European Green Deal, kufunikira kwa zinthu zobwezerezedwanso ndi zida zakula.Makamaka, pamabotolo a PET, zinthu zambiri zobwezerezedwanso (rPET) zimafunidwa ndi makampani ndi ogula.Kafukufukuyu adachitika m'malo a labotale omwe amatengera njira zamafakitale, kuti afufuze zomwe zingachitike pamtundu wa rPET pamalupu khumi ndi amodzi obwezeretsanso, ndicholinga chogwiritsa ntchito ma rPET ochulukirapo mobwerezabwereza.Kuzungulira kumaphatikizapo extrusion, solid state polycondensation (SSP), chowonjezera chachiwiri kutengera kupanga mabotolo, kutsuka kotentha ndi kuyanika.75% rPET ndi 25% namwali PET adatulutsidwa m'mizere khumi ndi imodzi kuti ayese kukonzanso ndi kupanga.Zitsanzo zinayesedwa ndi mankhwala, thupi ndi biologically.Ubwino wazinthu za rPET sunakhudzidwe moyipa.Ma parameters monga mtundu, ma viscosity amkati, kuchuluka kwa mankhwala ofunikira komanso kupezeka kwa zonyansa za mutagenic zitha kuyesedwa bwino.Ubwino wa zinthu zopangidwa mwina udatengera kukwezeka kwazinthu zomwe zidalowetsedwa.Njira yobwezeretsanso botolo la PET lotsekeka pogwiritsa ntchito rPET yofikira 75% idatheka potsatira zomwe akufuna, zomwe zikuwonetsa kuti mulingo uwu wazinthu zobwezerezedwanso ukhoza kusungidwa kwamuyaya popanda kusokoneza khalidwe;
