Ukubuka okufushane kwe-PCR
Okokuqala, yazi ukuthi i-PCR "ibaluleke kakhulu." Ngokuvamile, i-"PCR" yepulasitiki elahliwe ekhiqizwa ngemva kokusakazwa, ukusetshenziswa, kanye nokusetshenziswa ingaguqulwa ibe izinto zokusetshenziswa eziwusizo kakhulu zokukhiqiza izimboni ngokusebenzisa ukuphinda kusetshenziswe ngokomzimba noma ukuphinda kusetshenziswe amakhemikhali ukuze kufezwe ukuvuselelwa nokuvuselelwa kwezinsizakusebenza.
Izinto ezisetshenziswe kabusha njenge-PET, i-PE, i-PP, i-HDPE, njll. zivela kumapulasitiki angcolile akhiqizwa ukusetshenziswa kwabantu nsuku zonke. Ngemva kokucutshungulwa kabusha, zingasetshenziswa ukwenza izinto zokusetshenziswa zepulasitiki zezinto ezintsha zokupakisha. Njengoba i-PCR ivela ngemva kokusetshenziswa, uma i-PCR ingalahlwanga kahle, izoba nomthelela oqondile kakhulu emvelweni.Ngakho-ke, i-PCR okwamanje ingenye yamapulasitiki aphinde asetshenziswa anconywe yimikhiqizo ehlukahlukene.
Ngokusho komthombo wepulasitiki ephinde yasetshenziswa, ipulasitiki ephinde yasetshenziswa ingahlukaniswa ibeI-PCR kanye ne-PIR. Empeleni, kungakhathaliseki ukuthi yi-"PCR" noma ipulasitiki ye-PIR, konke kuyipulasitiki ephinde yasetshenziswa okukhulunywa ngayo embuthanweni wobuhle. Kodwa maqondana nomthamo wokusetshenziswa kabusha, i-"PCR" inenzuzo enkulu ngobuningi; maqondana nekhwalithi yokucubungula kabusha, ipulasitiki ye-PIR inenzuzo enkulu.
Izizathu zokuthandwa kwe-PCR
Ipulasitiki ye-PCR ingenye yezindlela ezibalulekile zokunciphisa ukungcola kwepulasitiki nokusiza "ukungathathi hlangothi kwekhabhoni".
Ngemizamo engapheli yezizukulwane eziningana zosokhemisi nonjiniyela, amapulasitiki akhiqizwa ngophethiloli, amalahle, kanye negesi yemvelo abe yizinto ezibalulekile empilweni yabantu ngenxa yesisindo sawo esincane, ukuqina kwawo, kanye nokubukeka kwawo okuhle. Kodwa-ke, ukusetshenziswa kabanzi kwamapulasitiki kuholela nasekukhiqizweni kwenqwaba yemfucuza yepulasitiki. Amapulasitiki okuvuselela kabusha ngemva komthengi (i-PCR) abe ngenye yezindlela ezibalulekile zokunciphisa ukungcoliswa kwemvelo kwepulasitiki nokusiza imboni yamakhemikhali ukuthi iqhubekele "ekungathathini i-carbon". Izinhlayiya zepulasitiki ezisetshenzisiwe zixutshwa ne-resin emsulwa ukudala imikhiqizo emisha ehlukahlukene yepulasitiki. Ngale ndlela, akugcini nje ngokunciphisa ukukhishwa kwe-carbon dioxide, kodwa futhi kunciphisa ukusetshenziswa kwamandla
Ukusebenzisa Amapulasitiki e-PCR: Ukuqhubekisela Phambili Ukuphinda Kusetshenziswe Imfucuza Yepulasitiki.
Uma izinkampani eziningi zisebenzisa amapulasitiki e-PCR, kulapho isidingo siba sikhulu khona, okuzokwandisa kakhulu ukuphinda kusetshenziswe amapulasitiki angcolile, futhi kuzoshintsha kancane kancane indlela yokusebenza kwebhizinisi lokuphinda kusetshenziswe amapulasitiki angcolile, okusho ukuthi amapulasitiki angcolile ambalwa agcwaliswa, ashiswe futhi agcinwe endaweni yemvelo.
I-policy push: Isikhala se-policy se-PCR plastics siyavuleka.
Thatha iYurophu njengesibonelo, isu lepulasitiki le-EU, ipulasitiki kanye nentela yokupakishaimithetho yamazwe afana neBrithani neJalimane. Isibonelo, i-British Revenue and Customs ikhiphe "intela yokupakisha yepulasitiki", kanti izinga lentela yokupakisha elingaphansi kuka-30% wepulasitiki ephinde yasetshenziswa lingamakhilogremu angu-200 ngethani. Indawo yokufunwa kwamapulasitiki e-PCR ivuliwe ngentela kanye nezinqubomgomo.
