Saib luv luv ntawm PCR
Ua ntej, paub tias PCR yog "muaj txiaj ntsig heev." Feem ntau, cov khib nyiab yas "PCR" tsim tom qab kev ncig, kev noj, thiab kev siv tuaj yeem hloov mus rau hauv cov khoom lag luam muaj txiaj ntsig zoo heev los ntawm kev siv lub cev los yog kev siv tshuaj rov ua dua tshiab kom paub txog cov peev txheej rov tsim dua tshiab thiab rov ua dua tshiab.
Cov khoom siv rov ua dua tshiab xws li PET, PE, PP, HDPE, thiab lwm yam los ntawm cov khoom siv pov tseg uas tsim los ntawm tib neeg kev noj txhua hnub. Tom qab rov ua dua, lawv tuaj yeem siv los ua cov khoom siv yas rau cov khoom ntim tshiab. Txij li PCR los ntawm tom qab noj, yog tias PCR tsis raug pov tseg, nws yuav muaj feem cuam tshuam ncaj qha rau ib puag ncig.Yog li, PCR tam sim no yog ib qho ntawm cov khoom siv rov ua dua tshiab tau pom zoo los ntawm ntau lub npe.
Raws li lub hauv paus ntawm recycled plastics, recycled plastics tuaj yeem muab faib uaPCR thiab PIR. Hais lus nruj me ntsis, txawm tias nws yog "PCR" lossis PIR yas, lawv yog cov khoom siv rov ua dua tshiab uas tau hais hauv lub voj voog zoo nkauj. Tab sis nyob rau hauv cov nqe lus ntawm recycling ntim, "PCR" muaj qhov kom zoo dua qhov kom muaj nuj nqis; nyob rau hauv cov nqe lus ntawm reprocessing zoo, PIR yas muaj qhov zoo tshaj plaws.
Yog vim li cas rau qhov nrov ntawm PCR
PCR yas yog ib qho ntawm cov lus qhia tseem ceeb los txo cov pa phem yas thiab pab "carbon neutrality".
Los ntawm kev siv zog tsis tu ncua ntawm ntau tiam neeg ntawm chemists thiab engineers, plastics uas tsim los ntawm roj av, thee, thiab natural gas tau dhau los ua cov ntaub ntawv tseem ceeb rau tib neeg lub neej vim lawv lub teeb yuag, durability, thiab zoo nkauj tsos. Txawm li cas los xij, kev siv ntau ntawm cov yas kuj ua rau cov khoom pov tseg ntau ntawm cov yas. Post-consumer recycling (PCR) plastics tau dhau los ua ib qho ntawm cov lus qhia tseem ceeb los txo cov pa phem ib puag ncig thiab pab kev lag luam tshuaj mus rau "carbon neutrality". Cov khoom siv yas rov siv dua yog sib xyaw nrog cov khoom siv nkauj xwb los tsim ntau yam khoom siv tshiab. Nyob rau hauv txoj kev no, tsis tsuas yog txo cov pa roj carbon dioxide emissions, tab sis kuj txo lub zog noj
Siv PCR Plastics: Pushing Plastic Waste Recycling Ntxiv Ntxiv.
Ntau lub tuam txhab uas siv PCR plastics, qhov kev thov ntau dua, uas yuav ua rau kom rov ua dua cov yas pov tseg ntxiv, thiab yuav maj mam hloov cov hom thiab kev lag luam ntawm cov khoom siv pov tseg rov ua dua tshiab, uas txhais tau hais tias cov khoom siv pov tseg tsawg dua yog landfilled, incinerated thiab khaws cia rau hauv. ib puag ncig ntuj.
Txoj cai thawb: Txoj cai qhov chaw rau PCR yas yog qhib.
Coj Europe ua piv txwv, EU plastics lub tswv yim, cov yas thiab ntim sekev cai lij choj ntawm lub teb chaws xws li Britain thiab Germany. Piv txwv li, British Revenue thiab Customs tau tshaj tawm "cov se ntim cov hnab yas", thiab cov nqi them se ntawm cov ntim tsawg dua 30% cov yas rov ua dua tshiab yog 200 phaus ib tuj. Qhov chaw thov rau PCR yas tau qhib los ntawm kev sau se thiab cov cai.
