Inkxalabo yehlabathi malunga nongcoliseko lweplastiki sele ikhona ixesha elide. Ukusukela ngo-2021, i-EU iya kuzivala ngokupheleleyo zonke iimveliso zeplastiki ezisetyenziswa kanye kuphela ezinokuthi ziveliswe kwezinye izinto ezizezinye ezifana nekhadibhodi, kubandakanywa iitafile zeplastiki, iindiza, iintonga zebhaluni, i-cotton Sticks, kunye neengxowa kunye nokupakishwa kwangaphandle okwenziwe ngeplastiki enokubola.
Nokuba iikomityi engagqunywanga inokumelana okuthile nokungena, isafuna umaleko wokugquma ukufezekisa le njongo xa isetyenziswa njengemveliso yokuphela njengetafile. Iphepha lesiseko elilahlayo le-cupstock elifakwe kwi-PP okanye ifilimu ye-PE kwelinye okanye kumacala omabini ukuhlangabezana neemfuno zokungangeni kwamanzi kunye ne-oyile. Ukuphunyezwa kokuvinjelwa kweeplastiki kuye kwakhawulezisa ukukhuthazwa kokugquma ngaphandle kweplastiki. Ke yintoni ukusebenza kweekomityi zokugquma ezingenaplastiki? Ngaba inokutshintsha ngokupheleleyoIikomityi zokwaleka ze-PE?
Emva kovavanyo kunye nothelekiso, xa iqondo lobushushu lengubo engeyiyo eyeplastiki linyuka liye kutsho kumaqondo angama-60 ngokukaCelsius, umphezulu wokugquma ubancangathi, kwaye okukhona umkhulu isixa sokugquma, kokukhona ubushushu obuphezulu, kokukhona bukhula ukufuma, kwaye kokukhona kucaca ngakumbi. imeko encangathi. Ezinye izinto zokugquma ezingezizo ezeplastiki zineempawu zokutywinwa kobushushu, eziqhubeka nokunyusa izinga lobushushu lokutywinwa kunye nokwandisa ixesha lokutywinwa kobushushu kuya kuba nefuthe elithile ekutywinweni, kodwa iphepha liya kuba tyheli kwaye libe brittle xa lishushu. ayifanelekanga.
Okwangoku, ingxaki enkulu ejongene neengubo zeplastiki ezingenazo iiplastiki zeikomityi yingxaki yokuncamathela xa kushushu. Undoqo wokuncamathela kufuneka ube kukuba isambatho sithambe ngenxa yobushushu. Emva koko, galela amanzi abilayo kwikomityi yephepha, kwaye ubushushu bamanzi buya kuthambisa isambatho kwaye siyenze incangathi, nto leyo eya kwenza umsebenzisi azive engonwabanga, kwaye abuze nokhuseleko lweekomityi zephepha. Nangona kunjalo, ukwandisa ukushisa okuthambileyo kwengubo kuya kuchaphazela ngokuqinisekileyo umsebenzi wayo wokuthotywa, eyona njongo yokuqala yokuphunyezwa kokuvinjelwa kweeplastiki.
