Kuongorora kwenguva pfupi kwePCR
Chekutanga, ziva kuti PCR "inokosha zvikuru." Kazhinji, marara epurasitiki "PCR" anowanikwa mushure mekutenderera, kushandiswa, uye kushandiswa anogona kushandurwa kuita zvinhu zvakakosha zvikuru zvekugadzira maindasitiri kuburikidza nekudzokorodza kana kudzokorodza makemikari kuti pave nekudzokorodza uye kudzokorodza zviwanikwa.
Zvinhu zvakadzokororwazve zvakaita sePET, PE, PP, HDPE, nezvimwewo zvinobva mumapurasitiki anogadzirwa nevanhu zuva nezuva. Mushure mekugadziriswazve, zvinogona kushandiswa kugadzira zvinhu zvepurasitiki zvekushandisa pakurongedza zvitsva. Sezvo PCR inobva mushure mekudyiwa, kana PCR ikasaraswa zvakanaka, ichave nemhedzisiro yakananga kunharaunda.Saka, PCR parizvino ndeimwe yemapurasitiki akadzokororwa anokurudzirwa nemakambani akasiyana-siyana.
Zvichienderana nekwakabva mapurasitiki akadzokororwa, mapurasitiki akadzokororwa anogona kukamurwa kuitaPCR uye PIRKutaura chokwadi, ingave iri "PCR" kana kuti PIR plastic, ese mapurasitiki akadzokororwa akambotaurwa mudenderedzwa rerunako. Asi maererano nehuwandu hwekudzokororwa, "PCR" ine mukana wakakwana muhuwandu; maererano nemhando yekugadzirisa, PIR plastic ine mukana wakakwana.
Zvikonzero zvekuzivikanwa kwePCR
PCR purasitiki ndeimwe yenzira dzakakosha dzekuderedza kusvibiswa kwepurasitiki uye kubatsira "kusapindirana kwekabhoni".
Kuburikidza nekuedza kusingaperi kwezvizvarwa zvakati wandei zvevanyanzvi vemakemikari nemainjiniya, mapurasitiki anogadzirwa kubva mupetroleum, marasha, uye gasi rechisikigo ave zvinhu zvakakosha muhupenyu hwevanhu nekuda kwehuremu hwawo hushoma, kugara kwenguva refu, uye chitarisiko chakanaka. Zvisinei, kushandiswa kwakanyanya kwepurasitiki kunotungamirawo mukuumbwa kwemarara epurasitiki akawanda. Mapurasitiki ekushandisa patsva mushure mevatengi (PCR) ave imwe yenzira dzakakosha dzekuderedza kusvibiswa kwezvakatipoteredza kwepurasitiki uye kubatsira indasitiri yemakemikari kufambira mberi ku "carbon neutral". Zvidimbu zvepurasitiki zvinodzokororwa zvinosanganiswa ne virgin resin kugadzira zvigadzirwa zvitsva zvakasiyana-siyana zvepurasitiki. Nenzira iyi, kwete chete kuderedza kuburitswa kwecarbon dioxide, asiwo kuderedza kushandiswa kwesimba.
Kushandisa PCR Plastiki: Kusimudzira Kudzokorodza Marara ePurasitiki.
Makambani anoshandisa mapurasitiki ePCR akawanda, kudiwa kwacho kunowedzera, izvo zvichawedzera kudzokororwa kwemapurasitiki emarara, uye zvichachinja zvishoma nezvishoma maitiro nekushanda kwebhizinesi rekudzokororwa kwemapurasitiki emarara, zvichireva kuti mapurasitiki mashoma anozadzwa, anopiswa uye anochengetwa munzvimbo yechisikigo.
Kurudziro yemutemo: Nzvimbo yemutemo yemapurasitiki ePCR iri kuvhurwa.
Semuenzaniso, funga nezveEurope, hurongwa hweEU hwemapurasitiki, mapurasitiki nemutero wekurongedza.mitemo yenyika dzakadai seBritain neGermany. Semuenzaniso, British Revenue and Customs yakaburitsa "mutero wekurongedza mapurasitiki", uye mutero wekurongedza wepurasitiki yakadzokororwa iri pasi pe30% i200 pounds patani. Nzvimbo yekudiwa kwemapurasitiki ePCR yakavhurwa kuburikidza nemitero nemitemo.
