Chii chaizvo chinonzi zvinhu zvePCR?
1. Chii chinonzi PCR zvinhu?
Zvinhu zvePCR chaizvoizvo imhando ye "purasitiki yakadzokororwa", zita rakazara ndiro Post-Consumer Recycled Material, kureva, zvinhu zvakadzokororwa mushure mevatengi.
Zvinhu zvePCR "zvinokosha zvikuru". Kazhinji, marara epurasitiki anokonzerwa nekutenderera, kushandiswa uye kushandiswa anogona kushandurwa kuita zvinhu zvekugadzira zvemaindasitiri zvakakosha zvikuru kuburikidza nekudzokorodza kana kudzokorodza nemakemikari, zvichiita kuti pave nekudzokorodza uye kudzokorodza zviwanikwa.
Semuenzaniso, zvinhu zvakadzokororwazve zvakaita sePET, PE, PP, uye HDPE zvinobva mumapurasitiki anogadzirwa kubva mumabhokisi ekudya kwemasikati anoshandiswa kazhinji, mabhodhoro eshampoo, mabhodhoro emvura ine mineral, mabara emuchina wekuwachisa, nezvimwewo. Mushure mekugadziriswazve, zvinogona kushandiswa kugadzira zvinhu zvitsva zvekurongedza.
Sezvo zvinhu zvePCR zvichibva pazvinhu zvakamboshandiswa mushure mekushandiswa, kana zvikasagadziriswa zvakanaka, zvichakanganisa zvakanyanya nharaunda. Saka, PCR ndeimwe yemapurasitiki akadzokororwa anokurudzirwa nemakambani akasiyana-siyana parizvino.
2. Sei mapurasitiki ePCR achifarirwa?
•(1). PCR plastiki ndeimwe yenzira dzakakosha dzekuderedza kusvibiswa kwepurasitiki uye kubatsira mu "kusapindira kwekabhoni".
Mushure mekuedza kusingaperi kwezvizvarwa zvakati wandei zvevanyanzvi vemakemikari nemainjiniya, mapurasitiki anogadzirwa kubva mupetroleum, marasha, negasi rechisikigo ave zvinhu zvakakosha muhupenyu hwevanhu nekuda kwehuremu hwawo hushoma, kugara kwenguva refu, uye runako. Zvisinei, kushandiswa kwakanyanya kwemapurasitiki kwakaitawo kuti pave nekuwanikwa kwemarara akawanda epurasitiki. Mapurasitiki ekushandisa patsva mushure mekushandiswa kwepurasitiki (PCR) ave imwe yenzira dzakakosha dzekuderedza kusvibiswa kwezvakatipoteredza kwepurasitiki nekubatsira indasitiri yemakemikari kufambira mberi ku "carbon neutralite".
Mapurasitiki akagadziriswazve anosanganiswa ne virgin resin kugadzira zvigadzirwa zvitsva zvakasiyana-siyana zvepurasitiki. Nzira iyi haingoderedzi chete kuburitswa kwecarbon dioxide, asiwo inoderedza kushandiswa kwesimba.
•(2)Shandisa PCR plastic kukurudzira kudzokorodza marara epurasitiki
Makambani akawanda anoshandisa mapurasitiki ePCR, kudiwa kwacho kunowedzera, izvo zvichawedzera kudzokororwa kwemapurasitiki emarara uye zvishoma nezvishoma zvinochinja modhi nemabasa ebhizinesi ekudzokororwa kwemarara epurasitiki, zvichireva kuti mapurasitiki mashoma achazadzwa, kupiswa uye kuchengetwa munzvimbo yakasikwa.
• (3)Kukurudzira mutemo
Nzvimbo yepamutemo yemapurasitiki ePCR iri kuvhurwa.
Semuenzaniso, funga nezveEurope, hurongwa hweEU hwepurasitiki uye mutemo wemitero yepurasitiki nekuisa zvinhu mumapurasitiki munyika dzakadai seBritain neGermany. Semuenzaniso, UK Revenue and Customs yakaburitsa "Mutero wePlastic Packaging". Mutero wepurasitiki wekuisa zvinhu nemapurasitiki akadzokororwa asingasviki 30% i200 pounds patani. Mutero nemutemo zvakavhura nzvimbo yekudiwa kwemapurasitiki ePCR.
3. Ndeapi makuru eindasitiri ari kuwedzera mari yavo muPCR plastics munguva pfupi yapfuura?
Parizvino, ruzhinji rwezvigadzirwa zvepurasitiki zvePCR zviri pamusika zvichiri kushandiswa pakugadzirisa zvinhu. Makambani akawanda emakemikari epasi rose ari kutevera kugadzirwa nekushandiswa kwezvigadzirwa zvepurasitiki zvePCR zvakagadziriswazve zvine makemikari. Vanotarisira kuona kuti zvinhu zvakagadziriswazve zvine mashandiro akafanana nemidziyo, uye zvinogona "kuderedza kabhoni".
•(1). BASF'Zvinhu zvakadzokororwa zveUltramid zvinowana chitupa cheUL
BASF yakazivisa svondo rino kuti polymer yayo yeUltramid Ccycled yakagadziriswazve yakagadzirwa pafekitori yayo yeFreeport, Texas, yakagamuchira chitupa kubva kuUnderwriters Laboratories (UL).
Sekureva kweUL 2809, ma polymer eUltramid Ccycled anodzokororwa kubva kumapurasitiki anodzokororwa mushure mekushandiswa (PCR) anogona kushandisa sisitimu yekuenzanisa huwandu kuti asangane nezvinodiwa zvekushandisa zvakadzokororwa. Mhando ye polymer ine hunhu hwakafanana nehwezvinhu zvakagadziriswa uye haidi kugadziriswa kune nzira dzechinyakare dzekugadzirisa. Inogona kushandiswa muzvishandiso zvakaita semafirimu ekurongedza, makapeti nefenicha, uye inzira inogara iripo pane zvinhu zvakagadziriswa.
BASF iri kutsvaga maitiro matsva emakemikari kuti irambe ichishandura mamwe mapurasitiki emarara kuita zvinhu zvitsva, zvinokosha. Nzira iyi inoderedza kuburitswa kwemagasi anodziya pasi uye zvinhu zvinopinda muzvinhu zvakasara uku ichichengetedza mhando yezvigadzirwa uye mashandiro azvo.
Randall Hulvey, Mutungamiriri weBhizinesi reBASF North America:
"Giredhi redu idzva reUltramid Ccycled rinopa simba repamusoro remakanika, kuomarara uye kugadzikana kwekupisa kwakafanana negiredhi rekare, uye zvichabatsira vatengi vedu kuzadzisa zvinangwa zvavo zvekuchengetedza hupenyu.""
•(2). Mengniu: Isa Dow PCR resin
Musi wa11 Chikumi, Dow naMengniu vakazivisa pamwe chete kuti vakabudirira kutengesa firimu rinopisa rinogadziriswazve resin mushure mevatengi.
Zvinonzwisisika kuti iyi ndiyo nguva yekutanga muindasitiri yezvekudya zvemumba kuti Mengniu isanganise simba rayo rezvezvakatipoteredza muindasitiri uye ibatane nevatengesi vezvinhu zvepurasitiki, vagadziri vemapakeji, vanodzokorodza zvinhu pamwe chete nedzimwe nhengo dzeindasitiri kuti vaone kudzokorodza nekushandisazve mapurasitiki, vachishandisa zvizere mapurasitiki akadzokororwa mushure mevatengi sefirimu remapakeji ezvigadzirwa.
Chikamu chepakati chefirimu rechipiri rinopisa rinopwanyika rinoshandiswa nezvigadzirwa zveMengniu chinobva kufomura yeresin yeDow's PCR. Fomura iyi ine 40% yezvinhu zvakadzokororwa mushure mekushandiswa uye inogona kuunza zviri mukati mefirimu rakadzokororwa kusvika 13%-24%, zvichiita kuti mafirimu akwanise kugadzirwa zvakaenzana neresin yakavimbika. Panguva imwe chete, inoderedza huwandu hwemarara epurasitiki munharaunda uye inoita kuti pave nekushandiswa kwakavharwa kwekugadzirisa pakugadzira.
•(3). Unilever: Yava kushandisa rPET kuti iwane zvinonhuhwirira zvayo, yova UK'mhando yekutanga yechikafu chePCR 100%
Muna Chivabvu, kambani yeUnilever inonzi Hellmann's yakachinja kuita 100% mushure mekushandiswa kwePET (rPET) yakazoshandiswazve mushure mekutengesa ndokuiburitsa muUK. Unilever yakati kana zvese izvi zvikatsiviwa ne rPET, zvaizochengetedza matani angangoita 1,480 ezvekushandisa gore rega rega.
Parizvino, inenge hafu (40%) yezvigadzirwa zveHellmann zvatove kushandisa mapurasitiki akadzokororwa uye zvakatotanga kushandiswa muna Chivabvu. Kambani iyi inoronga kushandisa mapurasitiki anogona kudzokororwa ezvigadzirwa izvi panosvika kupera kwa2022.
Andre Burger, mutevedzeri wemutungamiri wezvekudya kuUnilever UK neIreland, akati:"Hellmann wedu'Mabhodhoro ezvinwiwa ndiwo ekutanga muUK kushandisa mapurasitiki akadzokororwa 100% mushure mekushandiswa, kunyangwe mukuchinja uku kwave nematambudziko, asi ruzivo urwu ruchatibatsira kukurumidzisa kushandiswa kwepurasitiki yakadzokororwa muUnilever.'mamwe marudzi ezvekudya.""
PCR yave zita rekushandisaECO-zvinhu zvine hushamwari. Nyika zhinji dzekuEurope dzakashandisa PCR pakurongedza chikafu kuti ive nechokwadi chekuti chikafu chakazara.ECO-hushamwari.
Tiri vagadziri vane hunyanzvi mukugadzira mabhegi ekurongedza kofi kwemakore anopfuura makumi maviri. Tava mumwe wevagadziri vakuru vemabhegi ekofi muChina.
Tinoshandisa mavharuvhu eWIPF emhando yepamusoro kubva kuSwiss kuti kofi yenyu igare yakachena.
Tagadzira mabhegi asingakuvadzi nharaunda, akadai semabhegi anogadziriswa manyowa nemabhegi anogona kudzokororwa,uye zvinhu zvitsva zvePCR zvakaunzwa.
Ndidzo sarudzo dzakanakisisa dzekutsiva mabhegi epurasitiki echinyakare.
Tabatanidza katarogu yedu, ndapota titumirei rudzi rwebhegi, zvinhu, saizi uye huwandu hwamunoda. Kuti tikwanise kukutengerai.
