Ziyini ngempela izinto ze-PCR?
1. Yiziphi izinto ze-PCR?
Izinto ze-PCR empeleni ziwuhlobo "lwepulasitiki egaywe kabusha", igama eligcwele liyi-Post-Consumer Recycled material, okungukuthi, izinto ezigaywe kabusha zangemuva komthengi.
Izinto ze-PCR "zibaluleke kakhulu".Imvamisa, amapulasitiki alahlwayo akhiqizwa ngemuva kokuhanjiswa, ukusetshenziswa kanye nokusetshenziswa kungaguqulwa kube izinto ezingasetshenzisiwe zokukhiqiza ezibaluleke kakhulu ezimbonini ngokugaywa kabusha okungokoqobo noma ukugaywa kabusha kwamakhemikhali, ngokubona ukuvuselelwa kabusha kwensiza nokugaywa kabusha.
Isibonelo, izinto ezigaywe kabusha ezifana ne-PET, i-PE, i-PP, ne-HDPE zivela kumapulasitiki alahlwayo akhiqizwa ngamabhokisi esidlo sasemini asetshenziswa kakhulu, amabhodlela e-shampoo, amabhodlela amanzi amaminerali, imiphongolo yomshini wokuwasha, njll. Ngemva kokucubungula kabusha, angasetshenziswa ukwenza okusha. izinto zokupakisha..
Njengoba izinto ze-PCR zivela ezintweni ezisetshenziswa ngemva komthengi, uma zingacutshungulwa kahle, nakanjani zizoba nomthelela oqondile emvelweni.Ngakho-ke, i-PCR ingenye yamapulasitiki agaywe kabusha njengamanje anconywa yimikhiqizo ehlukahlukene.
2. Kungani amapulasitiki e-PCR ethandwa kangaka?
•(1).Ipulasitiki ye-PCR ingenye yezinkomba ezibalulekile zokunciphisa ukungcoliswa kwepulasitiki futhi ibe nomthelela "ekungathathi hlangothi kwekhabhoni".
Ngemva kwemizamo engapheli yezizukulwane eziningana zosokhemisi nonjiniyela, amapulasitiki akhiqizwa nge-petroleum, amalahle, negesi yemvelo asephenduke izinto ezibalulekile ekuphileni komuntu ngenxa yesisindo sazo esilula, ukuqina nobuhle bazo.Kodwa-ke, ukusetshenziswa kakhulu kwamapulasitiki kuye kwaholela ekukhiqizeni imfucumfucu yepulasitiki.Ipulasitiki ye-Post-consumer recycling (PCR) isiphenduke enye yezinkomba ezibalulekile zokunciphisa ukungcoliswa kwemvelo kwepulasitiki nokusiza imboni yamakhemikhali iqhubekele "ekungathathi hlangothi kwekhabhoni".
Amapulastiki asenziwe kabusha ahlanganiswe ne-virgin resin ukuze kwakhiwe imikhiqizo emisha yepulasitiki ehlukahlukene.Le ndlela ayigcini nje ukunciphisa ukukhishwa kwe-carbon dioxide, kodwa futhi inciphisa ukusetshenziswa kwamandla.
•(2).Sebenzisa ipulasitiki ye-PCR ukuze uqhubeke nokugqugquzela ukugaywa kabusha kwepulasitiki
Uma izinkampani eziningi ezisebenzisa amapulasitiki e-PCR, kukhula isidingo, okuzoqhubeza ukwandisa ukugaywa kabusha kwamapulasitiki angcolile futhi kancane kancane kuguqule imodeli nokusebenza kwebhizinisi lokugaywa kabusha kwepulasitiki, okusho ukuthi amapulasitiki amancane azolahlwa, ashiswe futhi agcinwe endaweni ezungezile.endaweni yemvelo.
• (3).Ukunyuswa kwenqubomgomo
Isikhala senqubomgomo yamapulasitiki e-PCR siyavuleka.
Thatha iYurophu njengesibonelo, isu lepulasitiki le-EU kanye nepulasitiki kanye nomthetho wentela wokupakisha emazweni afana neBrithani neJalimane.Isibonelo, i-UK Revenue and Customs ikhiphe "i-Plastic Packaging Tax".Izinga lentela lokupakishwa ngepulasitiki egaywe kabusha engaphansi kuka-30% ngamaphawundi angama-200 ngethani ngalinye.Intela nezinqubomgomo zivule isikhala sokufunwa kwamapulasitiki e-PCR.
3. Yiziphi izikhondlakhondla zemboni ezandisa utshalomali lwazo kumapulasitiki e-PCR muva nje?
Njengamanje, iningi lemikhiqizo yepulasitiki ye-PCR emakethe isasekelwe ekugayweni kabusha okungokoqobo.Izimboni zamakhemikhali zamazwe ngamazwe ziya ngokwanda zilandela ukuthuthukiswa kanye nokusetshenziswa kwemikhiqizo yepulasitiki ye-PCR egaywe kabusha ngamakhemikhali.Bathemba ukuthi bazoqinisekisa ukuthi izinto ezigaywe kabusha zinokusebenza okufanayo nokwezinto ezingavuthiwe., futhi ingafinyelela "ukunciphisa i-carbon".
•(1).BASF'Izinto ezisetshenziswe kabusha ze-Ultramid zithola isitifiketi se-UL
I-BASF imemezele kuleli sonto ukuthi i-Ultramid Ccycled recycled polymer ekhiqizwa endaweni yayo yaseFreeport, eTexas, isithole isitifiketi kwa-Underwriters Laboratories (UL).
Ngokuya nge-UL 2809, ama-polymers e-Ultramid Ccycled aphinde agaywa kabusha kusukela kumapulasitiki agaywe kabusha ngabathengi (PCR) angasebenzisa isistimu yebhalansi enkulu ukuze ahlangabezane nezindinganiso zokuqukethwe ezigaywe kabusha.Ibanga le-polymer linempahla efanayo nempahla eluhlaza futhi ayidingi ukulungiswa ezindleleni zokucubungula zendabuko.Ingasetshenziswa ezinhlelweni ezifana namafilimu okupakisha, okhaphethi kanye nefenisha, futhi iyindlela eqhubekayo yokuthatha izinto zokusetshenziswa.
I-BASF icwaninga izinqubo zamakhemikhali ezintsha ukuze iqhubeke nokuguqula amanye amapulasitiki alahlwayo abe yizinto ezintsha, ezibalulekile zokusetshenziswa.Le ndlela inciphisa ukukhishwa kwegesi ebamba ukushisa kanye nezinto ezisetshenziswayo zefosili ngenkathi igcina ikhwalithi nokusebenza komkhiqizo.
U-Randall Hulvey, uMqondisi Webhizinisi we-BASF eNyakatho Melika:
“Ibanga lethu elisha le-Ultramid Ccycled linikeza amandla afanayo aphezulu emishini, ukuqina kanye nokuzinza okushisayo njengamamaki endabuko, futhi kuzosiza amakhasimende ethu ukufeza izinhloso zawo zokusimama.”
•(2).I-Mengniu: Faka i-Dow PCR resin
NgoJuni 11, u-Dow noMengniu bamemezele ngokuhlanganyela ukuthi sebehwebe ngempumelelo ifilimu enciphayo yokushisa kweresin eshibhile yangemva komthengi.
Kuyaqondakala ukuthi kungokokuqala embonini yokudla yasekhaya ukuthi i-Mengniu ihlanganise amandla ayo emvelo yezimboni futhi ihlanganiswe nabahlinzeki bezinto zokusetshenziswa zepulasitiki, abakhiqizi bokupakisha, abahlaziyi kanye nezinye izinhlangano zamaketango embonini ukuze babone ukugaywa kabusha nokusetshenziswa kabusha kokupakishwa kwepulasitiki, ngokugcwele. ukusebenzisa amapulasitiki agaywe kabusha ngemuva komthengi njengefilimu yokupakisha yoMkhiqizo.
Isendlalelo esimaphakathi sefilimu yesibili enciphayo yokushisa esetshenziswa imikhiqizo ye-Mengniu sivela kufomula yenhlaka ye-Dow's PCR.Le fomula iqukethe u-40% wezinto ezigaywe kabusha zangemuva komthengi futhi ingaletha okuqukethwe okubalulekile okugaywe kabusha kusakhiwo sefilimu eshwabene iyonke ku-13% -24%, okuvumela ukukhiqizwa kwamafilimu anokusebenza okuqhathaniswa ne-virgin resin.Ngesikhathi esifanayo, inciphisa inani lemfucuza yepulasitiki endaweni futhi ibona ngempela ukusetshenziswa kwe-loop evaliwe yokugaywa kabusha kwamaphakheji.
•(3).I-Unilever: Ishintshela ku-rPET ngochungechunge lwayo lwe-condiment, iba yi-UK'uhlobo lokuqala lokudla lwe-PCR oluyi-100%.
NgoMeyi, uhlobo lwe-condiment yakwa-Unilever i-Hellmann's yashintshela ku-100% i-PET (rPET) egaywe kabusha ngabathengi futhi iyethula e-UK.I-Unilever ithe uma lonke lolu chungechunge lungathathelwa indawo i-rPET, izokonga cishe amathani angu-1,480 ezinto ezingavuthiwe minyaka yonke.
Okwamanje, cishe ingxenye (40%) yemikhiqizo ka-Hellmann isivele isebenzisa ipulasitiki egaywe kabusha futhi ishaya amashalofu ngoMeyi.Inkampani ihlela ukushintshela kupulasitiki ongasetshenziswa kabusha kulolu chungechunge lwemikhiqizo ekupheleni kuka-2022.
U-Andre Burger, iphini likamongameli wezokudla e-Unilever UK nase-Ireland, ubeke amazwana:“UHellmann wethu'Amabhodlela e-condiment awumkhiqizo wethu wokuqala wokudla e-UK ukusebenzisa u-100% wepulasitiki osetshenziswe kabusha wangemuva komthengi, nakuba kulolu shintsho Kube nezinselelo, kodwa ulwazi luzosenza sikwazi ukusheshisa ukusetshenziswa kwepulasitiki egaywe kabusha kakhudlwana kuyo yonke i-Unilever.'s ezinye izinhlobo zokudla.”
I-PCR isiyilebula leI-ECO-izinto ezinobungane.Amazwe amaningi ase-Europe asebenzise i-PCR ekufakweni kokudla ukuze aqinisekise u-100%I-ECO-enobungane.
Singumkhiqizi onguchwepheshe ekukhiqizeni izikhwama zokupakisha zekhofi iminyaka engaphezu kwengu-20.Sesibe ngomunye wabakhiqizi abakhulu bezikhwama zekhofi eChina.
Sisebenzisa amavalvu ekhwalithi angcono kakhulu e-WIPF avela eSwitzerland ukuze sigcine ikhofi lakho lilisha.
Senze izikhwama ezilungele imvelo, njengezikhwama ezivundisiwe kanye nezikhwama ezigaywa kabusha,kanye nezinto zakamuva ezethulwe ze-PCR.
Ziyizinketho ezingcono kakhulu zokushintsha izikhwama zepulasitiki ezivamile.
Kunamathiselwe ikhathalogi yethu, sicela usithumelele uhlobo lwesikhwama, impahla, usayizi kanye nenani elidingayo.Ngakho singakucaphuna.
