Ziyini ngempela izinto ze-PCR？
1. Ziyini izinto ze-PCR?
Izinto ze-PCR empeleni ziwuhlobo "lwepulasitiki ephinde yasetshenziswa", igama eliphelele yizinto eziphinde zasetshenziswa ngemuva komthengi, okungukuthi, izinto eziphinde zasetshenziswa ngemuva komthengi.
Izinto ze-PCR "zibaluleke kakhulu". Ngokuvamile, imfucuza yepulasitiki ekhiqizwa ngemva kokusakazwa, ukusetshenziswa kanye nokusetshenziswa ingaguqulwa ibe izinto zokusetshenziswa eziwusizo kakhulu zokukhiqiza izimboni ngokusebenzisa ukuphinda kusetshenziswe ngokomzimba noma ukuphinda kusetshenziswe amakhemikhali, okwenza kutholakale ukuvuselelwa kwezinsiza kanye nokuphinda kusetshenziswe.
Isibonelo, izinto ezisetshenziswe kabusha njenge-PET, i-PE, i-PP, ne-HDPE zivela kumapulasitiki angcolile akhiqizwa ngamabhokisi okudla kwasemini asetshenziswa njalo, amabhodlela e-shampoo, amabhodlela amanzi amaminerali, imiphongolo yomshini wokuwasha, njll. Ngemva kokucutshungulwa kabusha, zingasetshenziswa ukwenza izinto ezintsha zokupakisha.
Njengoba izinto ze-PCR zivela ezintweni ezisetshenziswe ngemuva kokusetshenziswa, uma zingacutshungulwa kahle, zizoba nomthelela oqondile kakhulu emvelweni. Ngakho-ke, i-PCR ingenye yepulasitiki ephinde yasetshenziswa enconywe yimikhiqizo ehlukahlukene njengamanje.
2. Kungani amapulasitiki e-PCR ethandwa kangaka?
•(1)Ipulasitiki ye-PCR ingenye yezindlela ezibalulekile zokunciphisa ukungcola kwepulasitiki futhi inegalelo "ekungathathi hlangothi kwekhabhoni".
Ngemva kwemizamo engapheli yezizukulwane eziningana zosokhemisi nonjiniyela, amapulasitiki akhiqizwa ngophethiloli, amalahle, kanye negesi yemvelo abe yizinto ezibalulekile empilweni yabantu ngenxa yesisindo sawo esincane, ukuqina kwawo, kanye nobuhle bawo. Kodwa-ke, ukusetshenziswa kabanzi kwamapulasitiki nakho kuholele ekukhiqizweni kwenqwaba yemfucuza yepulasitiki. Ipulasitiki yokuvuselela kabusha ngemuva komthengi (i-PCR) ibe ngenye yezindlela ezibalulekile zokunciphisa ukungcola kwemvelo kwepulasitiki nokusiza imboni yamakhemikhali ukuthi iqhubekele "ekungathathini uhlangothi kwekhabhoni".
Ama-pellet epulasitiki asetshenziswe kabusha axutshwa ne-virgin resin ukudala imikhiqizo emisha ehlukahlukene yepulasitiki. Le ndlela ayigcini nje ngokunciphisa ukukhishwa kwe-carbon dioxide, kodwa futhi inciphisa ukusetshenziswa kwamandla.
•(2)Sebenzisa ipulasitiki ye-PCR ukuze ukhuthaze kakhulu ukuphinda usebenzise ipulasitiki elahliwe
Uma izinkampani eziningi ezisebenzisa amapulasitiki e-PCR, kulapho isidingo siba sikhulu khona, okuzokwandisa kakhulu ukuphinda kusetshenziswe amapulasitiki angcolile futhi kushintshe kancane kancane imodeli kanye nokusebenza kwebhizinisi kokuphinda kusetshenziswe amapulasitiki angcolile, okusho ukuthi amapulasitiki angcolile ambalwa azogcwaliswa, ashiswe futhi agcinwe endaweni ezungezile.
• (3). Ukukhuthazwa kwenqubomgomo
Isikhala senqubomgomo yamapulasitiki e-PCR siyavuleka.
Thatha iYurophu njengesibonelo, isu lepulasitiki le-EU kanye nomthetho wentela yepulasitiki kanye nokupakisha emazweni afana neBrithani neJalimane. Isibonelo, i-UK Revenue and Customs ikhiphe "iNtela Yokupakisha Yepulasitiki". Izinga lentela lokupakisha ngepulasitiki esetshenziswe kabusha engaphansi kuka-30% lingamakhilogremu angu-200 ngethani. Intela kanye nezinqubomgomo zivule isikhala sokufunwa kwamapulasitiki e-PCR.
3. Yiziphi izinkampani ezinkulu ezikhulisa ukutshalwa kwezimali kwazo kumapulasitiki e-PCR muva nje?
Njengamanje, iningi lemikhiqizo yepulasitiki ye-PCR emakethe isasekelwe ekusetshenzisweni kabusha ngokomzimba. Izimboni eziningi zamakhemikhali zamazwe ngamazwe zilandela ukuthuthukiswa nokusetshenziswa kwemikhiqizo yepulasitiki ye-PCR esetshenziswe kabusha ngamakhemikhali. Banethemba lokuqinisekisa ukuthi izinto ezisetshenziswe kabusha zisebenza ngendlela efanayo nezinto zokusetshenziswa, futhi zingafinyelela "ukunciphisa ikhabhoni".
•(1). I-BASF'Izinto ezisetshenziswe kabusha ze-Ultramid zithola isitifiketi se-UL
I-BASF imemezele kuleli sonto ukuthi i-polymer yayo ephinde yasetshenziswa i-Ultramid Ccycled ekhiqizwe esitshalweni sayo iFreeport, eTexas, ithole isitifiketi esivela ku-Underwriters Laboratories (UL).
Ngokusho kwe-UL 2809, ama-polymer e-Ultramid Ccycled aphinde asetshenziswe kusukela kumapulasitiki aphinde asetshenziswa ngemuva komthengi (PCR) angasebenzisa uhlelo lokulinganisela isisindo ukuze ahlangabezane nezindinganiso zokuqukethwe okuphinde kwasetshenziswa. Ibanga le-polymer linezakhiwo ezifanayo nezinto zokusetshenziswa futhi alidingi ukulungiswa ezindleleni zokucubungula zendabuko. Lingasetshenziswa ezicelweni ezifana namafilimu okupakisha, amakhaphethi kanye nefenisha, futhi liyindlela eqhubekayo yokuthatha izinto zokusetshenziswa.
I-BASF icwaninga izinqubo ezintsha zamakhemikhali ukuze iqhubeke nokuguqula amanye amapulasitiki angcolile abe izinto zokusetshenziswa ezintsha neziyigugu. Le ndlela inciphisa ukukhishwa kwamagesi okushisa ukushisa kanye nezinto zokusetshenziswa kwezinto zasendulo ngenkathi igcina ikhwalithi kanye nokusebenza komkhiqizo.
URandall Hulvey, uMqondisi Webhizinisi LaseNyakatho Melika we-BASF:
"Ibanga lethu elisha le-Ultramid Ccycled linikeza amandla aphezulu okusebenza, ukuqina kanye nokuzinza kokushisa okufanayo namazinga endabuko, futhi kuzosiza amakhasimende ethu ukufeza imigomo yawo yokuzinza."
•(2). Mengniu: Faka i-resin ye-Dow PCR
Ngomhlaka-11 Juni, uDow noMengniu bamemezele ngokubambisana ukuthi baphumelele ekuthengiseni ifilimu encibilikisa ukushisa ye-resin ephinde yasetshenziswa ngemuva komthengi.
Kuyaqondakala ukuthi lokhu kungokokuqala embonini yokudla yasekhaya ukuthi iMengniu ihlanganise amandla ayo emvelo yezimboni futhi ihlangane nabaphakeli bezinto zokusetshenziswa zepulasitiki, abakhiqizi bokupakisha, abasebenzisa kabusha kanye nabanye abathintekayo embonini ukuze baqaphele ukuphinda kusetshenziswe futhi ukuphinda kusetshenziswe ukupakisha kwepulasitiki, besebenzisa ngokugcwele amapulasitiki asetshenziswe kabusha ngemuva komthengi njengefilimu yokupakisha yomkhiqizo.
Ingqimba ephakathi yefilimu yesibili yokufutha encibilikayo esetshenziswa yimikhiqizo yeMengniu ivela kwifomula ye-resin ye-Dow's PCR. Le fomula iqukethe izinto ezisetshenziswe kabusha ezingama-40% ngemuva komthengi futhi ingaletha okuqukethwe kwezinto ezisetshenziswe kabusha esakhiweni sefilimu yokuncibilika iyonke ku-13%-24%, okuvumela ukukhiqizwa kwamafilimu ngokusebenza okufana ne-resin eyi-virgin. Ngesikhathi esifanayo, inciphisa inani lemfucuza yepulasitiki emvelweni futhi ifezekisa ngempela ukusetshenziswa okuvaliwe kokuphinda kusetshenziswe amaphakheji.
•(3). I-Unilever: Ishintshela ku-rPET ukuze ithole uchungechunge lwayo lwezinongo, yaba yi-UK'Uhlobo lokuqala lokudla lwe-PCR oluyi-100%
NgoMeyi, uhlobo lwe-Unilever lwe-Hellmann's lwashintshela ku-100% ngemuva kokusetshenziswa kabusha kwe-PET (rPET) futhi lwayiqalisa e-UK. I-Unilever ithe uma lonke lolu chungechunge lungathathelwa indawo yi-rPET, luzosindisa cishe amathani ayi-1,480 ezinto zokusetshenziswa minyaka yonke.
Njengamanje, cishe ingxenye (40%) yemikhiqizo kaHellmann isivele isebenzisa ipulasitiki ephinde yasetshenziswa futhi ifika emashalofini ngoMeyi. Le nkampani ihlela ukushintshela kupulasitiki ephinde yasetshenziswa kulolu chungechunge lwemikhiqizo ekupheleni kuka-2022.
U-Andre Burger, iphini likamongameli wezokudla e-Unilever UK nase-Ireland, uphawule kanje:"I-Hellmann yethu'Amabhodlela ezinongo ayindlela yethu yokuqala yokudla e-UK ukusebenzisa ipulasitiki ephinde yasetshenziswa ngo-100% ngemuva kokuthengwa, yize kulokhu kube nezinselelo, kodwa ulwazi luzosisiza ukuthi sisheshise ukusetshenziswa kwepulasitiki ephinde yasetshenziswa kakhulu kulo lonke elase-Unilever.'ezinye izinhlobo zokudla."
I-PCR isibe ilebula le-I-ECO-izinto ezinobungane. Amazwe amaningi aseYurophu asebenzise i-PCR ekupakisheni ukudla ukuqinisekisa ukuthi ukudla kuphephile.I-ECO-enobungane.
Singumkhiqizi ogxile ekukhiqizeni izikhwama zokupakisha ikhofi iminyaka engaphezu kwengu-20. Sesibe ngomunye wabakhiqizi abakhulu bezikhwama zekhofi eShayina.
Sisebenzisa ama-valve e-WIPF asezingeni eliphezulu avela eSwitzerland ukuze sigcine ikhofi yakho isha.
Sithuthukise izikhwama ezinobungani nemvelo, njengezikhwama ezifakwa umquba kanye nezikhwama ezingasetshenziswa kabusha,kanye nezinto zakamuva ze-PCR ezethulwe.
Yizona zinketho ezinhle kakhulu zokushintsha izikhwama zepulasitiki ezivamile.
Sinamathisele ikhathalogi yethu, sicela usithumelele uhlobo lwesikhwama, izinto zokwakha, usayizi kanye nenani olidingayo. Ukuze sikucaphunele.
