Indima Yokugranula kubukhulu bokuvuselela amaphutha ne-“Circular Economy”

Ukuthi Amagranula Okuvuselela Amaphutha Kuyenza Yini Amaphutha Ukuba Yizinto Ezinqinisekile Zokuvuselela Kwase-PCR

Izindlela Zokusebenza: Ukunciphisa Isize, Ukususa Amasimbi, Nokulawula Ukuphakanyiswa Kwesikhundla Sokugranula

Isithuthukisi sezinkokhelo esisha esemoderni sasebenza izinyathelo ezintathu eziphambili ukwenza izinkokhelo ezisuka kwezinto ezenziwe ngabantu zibe yizinhlobo ezingenakwazi ukusebenza ngokuphelele. Okokuqala, ukunciphisa isize kususa izinto ezingabi ngezinye—njengamabhasi, amabhokisi, nokuthi amafilm—kubhokisi emincane neyinhlobo eyodwa yokubhokisi okanye izinkhokho. Lokhu kongena esibonakaleni sokunquma ukuzikhanda kwezinhlobo zokucwasha nokuhambisana kwesikhathi sokufaka. Okwesibili, izinhlobo zokususa izinto ezingahambisi zikhiqiza izilabel, izihlangothi, izilimi, namazwi okugcina ngokusebenzisa izinhlobo zokucwasha eziningi, izinhlobo zokuhlanganisa amagama, nezinhlobo zokususa izinto ngokulingana nomkhondo. Okwesithathu, ukulawula ngokuphelele kwezinhlobo zokubhokisa, ispeed yomshini wokubhokisa, nokuhlela kwamakhnife kuyasekela ukubhokisa ngokuphelele—okuyisisekelo sokubhokisa ngokuphelele kwezinhlobo zokufaka kwezinhlobo zokufaka kanye nezinhlobo zokufaka ngokuphelele. Izinhlobo zokubhokisa ezinamandla ayisisekelo yokubhokisa ngokuphelele kuyasusa izinhlobo zokubhokisa zokubhokisa ngokuphelele, kuyadonsa ukuvulwa kwezinhlobo, kanye kuyasiza ekubeni kubhekwe ngokuphelele kwezinhlobo zokubhokisa. Uma akukho leli hlobo lokubhokisa ngokuphelele, izinkokhelo ezisuka kwezinto ezenziwe ngabantu ziyakwenzela ukuba zibe nezinto ezingahambisi kanye nezinhlobo ezingahambisi okuyakubeka phansi kokuphakamisa, ukubona, nokubhekwa ngokuphelele kwezinhlobo zokubhokisa.

I-Granulator ne-Shredder: Kungani Ukugranulisa Ngokuphelele Kuyisisekelo Sokubuyisela Isibhakabhaka Esikhundleni Sesibhakabhaka

Ama-granulators ahluke ngokuyisisekelo kuma-shredders ngekhwalithi yokukhipha nenhloso yokusebenza. Izingxenye ezichotshozwayo zidiliza izinto zibe izingcezu ezinkulu, ezingalingani, ezinama-geometry angahambisani, ezilungele ukunciphisa ivolumu yokuqala kodwa ezinganele ukuvuselelwa kwezinto eziwusizo kakhulu. Ama-granulator asika ngommese ojikelezayo ngokumelene nommese obekwe embhedeni, akhiqize ama-granules ahlanzekile, alawulwa ubukhulu. Lokhu kucacisa kubalulekile ekuvuseleleni ibhodlela ngebhodlela, lapho i-PCR kufanele ihambisane nokusabalalisa kwesisindo samangqamuzana nokuziphatha kwe-rheological ye-virgin PET noma i-HDPE. Ukulawulwa kokubekezelelana okuqinile futhi kunciphisa izinhlayiya nothuli, okungase kuvimbe amaphakethe esikrini, kucekele phansi ngesikhathi sokuxosha, futhi kwenze kube khona amaphuzu okuqhumisa. Ukuma kwe-granule okuhambisanayo kunciphisa kakhulu ukufunwa kwamandla ngesikhathi sokuncibilika futhi kuthuthukisa ukuhlakazeka kwezithasiselo ezifana nama-stabilizers noma ama-colorants. Ngenxa yalokho, ama-MRF amaningi manje ahlanganisa amayunithi e-granulation ngqo ngemuva kokuhlunga nokuwashakudala i-loop evaliwe, elungele ukucutshungulwa impahla eluhlaza ehlangabezana nezindinganiso zokupakisha ukudla nemithi. Ukukhetha phakathi kokuchoboza nokwenza amagremu kunquma ukuthi izinto ezisetshenzisiwe zifanelekile yini ukusetshenziswa kwe-premiumnoma zihlala zisetshenziswa njengezimpahla ezisetshenzisiwe.

Amathuba Okuziphatha Kwesifunda Nokuziphatha Kwesigaba Sokuthuthukisa Ukusebenzisa Amasimu Okususa Isilwane Esithile

Amasimu Okusiza Kukhona, Amasimu Okususa Isilwane Esithile, Nokuthiwa Kokubhala Isilwane Esisuswa Ngokuphelele

Amagovernment ethu yonke ayabeka amandla kumthetho ukuthuthukisa ukubuyela kwesilwane esithile—futhi amasimu okususa asihlukaniswa ngokusebenza njengomkhakha wokuziphatha. Amasimu Okusiza Kukhona (EPR) ayashintsha umlando wokuphatha nokuziphatha kwezinto zokugcina kokuphela kubazalisi, futhi ayavuma ukuthenga izinto ezinokususwa ngokuphelele kanti isikhundla sokuphatha ngokuphelele sokususa isilwane esithile. Amasimu okususa isilwane esithile kuzinto zokufaka izinto ezingaphansi—njengaleso kwe-UK nase-Spain—ayakhula umhlakelo wokuphatha phakathi kwezinto zokufaka izinto ezingaphansi nezinto zokufaka izinto ezingasuswa, okwenza i-PCR ibe yinkambo yokuqondisa. Ngakumbi, amandla okuthiwa kokubhala isilwane esisuswa ngokuphelele—njengaleso kwe-EU yokuthiwa kokubhala kwe-30% kwezinto zokufaka izinto ezingaphansi zokudla ngokuphela ngo-2030—ayadala umlando wokuthenga okuphelele wezinto zokufaka izinto ezingasuswa, okunamathuba okuthenga okuphelele, okungafani noma okungasuswa. Lezi zimithetho azizange ziyakhula kuphela amanani ayo aya kususa isilwane esithile; ziyakhula isibalo sokuthi ikhwalithi amakhampani akhangelela manje ukwamukela izinkokhelo eziningi—izilinganiso zokulawula ziyadinga izinkokhelo ezingaphansi kwezilinganiso ezikhulu zokubonwa ngokwesibonelo, zokuphatha, nokuthi zingakhathali imithombo. Lokhu kuyabavuma ukusebenza okusheshayo kwezinkokhelo zokuvuselela izinkokhelo eziyenzelwe ku-Europe, North America, kunye ne-Southeast Asia.

Isisekelo Sokuqhubeka Kwamanqubu: Ukugxekwa Kwamakhampani Okuvuselela Izinkokhelo Emagumbini Yokuzilungiselela Kunye Nezihub Zokuvuselela Izinkokhelo Zokusebenzisa Kabusha

Ngaphandle kokulawula, izinguquko zesimiso esakhiweni semfucuza zifaka ukufakelwa kwamagranula emnyombweni wamaketanga okuphakelayo ajikelezayo. Izindawo zanamuhla zokuvuselela izinto (MRFs) ngokuya zifaka imigqa ekhethekile yokuhlunga phansi kokuhlunga nokuwasha ukuguqula ama-balles ahlukanisiwe abe yi-granulate efanayo, elungele i-extruder. Lokhu kuhlanganiswa kuqeda ukuphathwa kabili, kunciphisa ukuwohloka okuhlobene nokuthutha, futhi kunciphise isikhathi sokuthengiswa kwe-PCR. Ngokufanayo, izikhungo ze-PCR eziphakathi nendawo ngokuvamile ezihlala ndawonye namanethiwekhi okuqoqa izifunda zisebenzisa amayunithi okuqoqa ama-granulation aphezulu ukuze zisebenzele ama-converter amaningi, zehlise imali etholwe ngethani ngalinye nezindleko zokusebenza. Ukuguquguquka kwemigomo yenqubomgomo kanye nokuguquguquka kwengqalasizinda kudala umjikelezo wokuziqinisa: imigomo yokulawula iqhuba ukufunwa kwe-PCR eqinisekisiwe, edinga ukunikezwa okuqhubekayo kwe-granulate, okubuye kuqinisekise ukutshalwa kwezimali ezinhlelweni ezihlanganisiwe zokuk Ngenxa yalokho, ukugaya izinto ezincane kusuke kungesona isinyathelo sokuqeda esiyimfuneko kube yikhono eliyisisekelo esakhiweni sokuphinda sisebenzise izinto ezincane.

Ukuphatha Ngokuphelele Nokuthanda Kwezindlela Zokusebenza Zebhokisi Zokugrana Kwamanzi Okwamanje

Ukuphatha Ngokuphelele, Ukuvumela Ukuthi Kwenzeke Ngokuphelele, Nokunciphisa Isibalo Sokulwa Kwesikhundla Sokuthengisa I-PCR

Amathuluzi anamuhla okuvuselela amapulasitiki anikeza amandla okuphila okuqhubekayo kanye nezinzuzo zokusebenza. Amandla amasha okuqhuba imoto, izinhlelo ezihlelwe kahle ze-hydraulic, nokuhlanganiswa kokubuyiselwa kokushisa kunciphise ukusetshenziswa kwamandla athile ngo-20%-30% uma kuqhathaniswa namamodeli amadalaehlisa ngqo izindleko zokusebenza kanye nomfutho wekhabhoni wokukhiqiza i-PCR. Umthamo nawo ukhuphuke kakhulu: amayunithi anamandla amakhulu manje asecubungula ngokuthembekile amathani angaphezu kwe-1 ngehora ngenkathi egcina ukuyekelela okuqinile kobukhulu, okwenza izikhungo zikwazi ukukhulisa umkhiqizo we-PCR ngaphandle kokwanda okuhambisanayo ekusetshenzisweni kukagesi noma endaweni ephansi. Ngokuphathelene nokuthuthwa kwezinto, ukubeka ama-granulation units eduze kwama-MRF, izikhungo zokuqoqa, noma ngisho namapaki ezimboni kunciphisa uchungechunge lokuthengwa kwezinto, kususa ukuthuthwa kwezinto ezincane ezincane, ezinesisindo esikhulu. Izinhlelo zokugaya ezihambayo nezingaguquguquki zandisa le nzuzo, zivumela ukucutshungulwa endaweni ezitolo ezinkulu, ezitshalweni zokugcwalisa amabhodlela noma ezindaweni zokugcina izinto zomasipala. Uma zihlanganiswa nokuklanywa kohlelo oluvuliwe nokubhekwa kwenqubo ngesikhathi sangempela, la madivayisi asiza ukuguqula i-PCR isuke ekubeni umkhiqizo osheshayo ibe yinto ebikezelayo, esebenza kahle kakhuluyenza ukuvuselelwa kwepulasitiki kungadingeki nje kuphela emvelweni, kodwa futhi kube namandla kwezomnotho
