Mapurasitiki ekurongedza angadzokororwe sei? Ndeapi tekinoroji mafambiro anofanirwa kutariswa?
Zhizha rino, kurongedza kwepurasitiki kunorova nhau nguva dzose! Chekutanga, bhodhoro regirini reUK nomwe rakachinjirwa kuita pachena, uye Mengniu naDow vakaziva maindasitiri efirimu rinopisa rinopisa rine PCR zvinhu. Uku ndiko kuedza kwekutanga kwaMengniu kushandisa PCR mupakeji yechipiri.
Kune zvakare nyika dzakawanda inogadzira ice cream foneri (mubatanidzwa pakati peFinch neRR) uyo akaraira 100million Z inovandudzwa polypropylene ice cream makapu. Ice cream yakaputirwa mu polypropylene yakadzokororwa ichatengeswa muItaly.
Iwo epasi pepfungwa yekugadzira epurasitiki yekurongedza tekinoroji muzvikamu izvi zvakasiyana zvakafanana: recyclepalagging haisisiri sirogani, asi "yakavakirwa" muratidziri. Recyclable packaging iri kuita basa rinowedzera kukosha.
Zvinoenderana nerepot uye dat, musika wepasi rose wekurongedza epurasitiki unotarisirwa kusvika pamadhora zana nemakumi maviri neshanu nemazana mashanu emadhora panosvika 2028, nehuwandu hwekukura kwepagore hwe6%, iyo inogona kudzokororwa kurongedza account chikamu chikuru.
Mapurasitiki ekurongedza angadzokororwe sei? Ndeapi tekinoroji mafambiro anofanirwa kutariswa?
01 single material inovandudza zvakanyanya kukosha kwakapfava kwekurongedza kudzokorodza
Mumakore achangopfuura, imwe chete yekurongedza mhinduro ine yakanaka kukosha yekudzokorodza yakafumurwa, uye yakawana kutsiviwa kweakasiyana ezvinyorwa zvinoumbwa mune mamwe maapplication. Kuenzaniswa neakawanda-layer composite zvinhu, imwe chete yepurasitiki yekurongedza haidi kubviswa mushure mekushandiswa, uye kukosha kudzokororwa kunovandudzwa zvakanyanya. Kungave mukurongedza kwakaoma kana kurongedza zvinyoro, zvinhu zvega zvinoremekedzwa zvakanyanya.
Semuenzaniso: demetallized yakazara PE pombi musoro
Mumazuva ese kemikari yakaoma kurongedza, iyo yechinyakare pombi musoro inogona kunge iine zvakasiyana zvinhu, uye mune dzimwe nguva, inogona kutoomesa maitiro ekudzokorodza. Iyi mhando yemusoro wepombi ine epurasitiki uye simbi yakasanganiswa chimiro inowedzera huchokwadi hwekuzorongedza uye kudzokorodza zvakare.
Imwe muenzaniso: zvese PE chikafu chinochinjika kurongedza chinopokana neokisijeni uye hunyoro-uchapupu
Mumunda wekurongedza zvinyoro zvechikafu, kurongedza kwechinhu chimwe kwakapinda zvishoma nezvishoma muchikafu chevana uye zvigadzirwa zvemukaka. Semuyenzaniso, kambani yeGarbo inopa chinhu chimwe chete chevana chikafu chekurongedza bhegi kune yayo organic banana mango puree. Kuburikidza nekuenzanisa, kurongedza firimu nechinhu chimwe chete kuri nyore kudzokorodza.
02 pachena PET bhodhoro rinopaza ruvara bhodhoro kudzokorodza kwakaoma
Mukudzokorodzazve kwemabhodhoro ePET, mabhodhoro ePET ane mavara anozowedzera kuoma kwekuzodzokorodza uye kuderedza kukosha kwekudzokorora, nepo mabhodhoro ePET akajeka ari nyore kudzokorodza. Pamusoro pezvo, mabhodhoro ePET akajeka zvakare ari nyore kusimudzira kukwezva kwemasherufu ezvigadzirwa.
Naizvozvo, mabhodhoro akajeka et ave achinyanya kufarirwa mumakore maviri apfuura. Coca Cola yakashandura bhodhoro rayo rechando remakore makumi mashanu kubva pagirinhi kuenda pamhene makore maviri apfuura, uye manomwe kumusoro kuUK achatangawo zhizha rino kushandura 375m, 500m uye 600ml FET kurongedza kubva paruvara rwekutanga kumucheto kuti ruve pachena kuitira kudzokorodza gare gare. Pamusoro peCoke Sprite uye nomwe kumusoro kwakajeka kurongedza, agenlian mugadziri wemukaka mastelene HNOS achatangawo kushandisa bhodhoro rakajeka rePET rakagadzirwa neAmcor kuzadza mukaka waro mutsva.
03 shandisazve PCR uye shandura marara kuita pfuma
Iro zita rakazara rePCR is post consumerreydedmateral, zvinoreva kuti post mutengi yakadzokororwa resin muChinese, kana PCR kwenguva pfupi. Inowanzo gadzirwa nezvidimbu zvepurasitiki zvitsva mushure mekugadzirisa zvakare tsvina mapurasitiki uye kuronga, kuchenesa uye zvidimbu zvemugwagwa nehurongwa hwekudzokorora. Ichi chepurasitiki chine chimiro chakafanana nepurasitiki isati yadzokororwa. Kana zvimedu zvepurasitiki zvitsva zvasanganiswa neresin yekutanga, zvigadzirwa zvepurasitiki zvitsva zvakasiyana zvinogona kugadzirwa. Iyi nzira haisi kungoderedza carbon dioxide emissions, asiwo inoderedza kushandiswa kwesimba. PCR inogona kudzokororwa zvinhu zvechipfuyo, PE, PP, HDPE, nezvimwe.
Mitemo yeEU inokurudzira mabhizinesi kuvandudza PCR application
IEuropean Union's disposable plastics Directive inoda kuti chikamu chezvikamu zvepurasitiki zvakadzokororwa mumabhodhoro echipiri eP PE zvinofanira kuwedzerwa kusvika 25% kubva muna 2025. Kubva 2030, chikamu chezvikamu zvepurasitiki zvakashandiswa zvakare mumabhodhoro epurasitiki ezvinwiwa zvinofanira kusvika 30%, PCR zvinhu mukati. kurongedza account ye30%, uye PCR zvinhu uye chikamu chinangwa cheEurasia Group i40%.
Kuwedzera chikamu chePCR zvinhu mukurongedza kwave imwe yenzira dzakakosha dzemakambani eFMCG kuti awane vision 2025 kana vision 2030. Unilever inoronga kuwana 25% yePCR zvinhu mukurongedza panosvika 2025, uye boka reMars rinoronga kubudirira kurongedza panosvika 2025. Muna Chikumi gore rino, Coca Cola yakaramba ichiwedzera chimiro chayo chakasimba muEurope uye yakasimudzira kugadzirwa uye kushandiswa kwemabhodhoro ePET muItari neGermany. Pakutanga, yakazivisa kugadzira zvishoma nezvishoma 100% pet mabhodhoro muNetherlands, Norway, Sweden nedzimwe nzvimbo.
