Musi waZvita 7, 2022, masangano matanhatu ekuchengetedza kwezvakatipoteredza, akabatana akapa "Chikumbiro chekurambidza kugadzirwa uye kushandiswa kwemapurasitiki anoora oxo", achidaidzira makambani kuti arege kugadzira nekutenga zvigadzirwa zvine mapurasitiki anoshatisa, uye asisazvisimudzire zvisirizvo. zvigadzirwa zvegirini uye zvine hushamwari kwezvakatipoteredza; uye inokurudzira kuti madhipatimendi ehurumende akakodzera ape mitemo yekurambidza kugadzirwa, kutengesa uye kushandiswa kwezvigadzirwa zvepurasitiki zvinoshatisa.
Munguva ino yekureruka uye nyore, mapurasitiki ave chikamu chakakosha chehupenyu hwevanhu vazhinji.Takeaway lunch boxes, express packages, shopping plastic bags... Izvi zvigadzirwa zvepurasitiki zvinoraswa hazvingounze vanhu zviri nyore, asiwo zvinokonzeresa mutoro mukuru pane zvakatipoteredza.Kana isina kuraswa zvakanaka, tsvina yepurasitiki inodonhedza mukati menzvimbo uye yova "kusvibiswa kwakachena".
Sechiyero chakakosha chebudiriro yegirinhi yenyika yangu, kudzivirira kusvibiswa uye kutonga kwakateererwa.Mukupindura dambudziko rekusvibiswa kwepurasitiki, muna Ndira 2020, National Development and Reform Commission uye Ministry of Ecology and Environment vakabatana vakapa "Maonero eKuwedzera Kusimbisa Plastic Pollution Control", inozivikanwa seyakanyanya kuomesesa "plastic restriction order". " munhoroondo.Nekudaro, zvigadzirwa zvepurasitiki zvakapinda mune zvese zvehupenyu hwevanhu.Sechikamu chedzimwe nzira dzezvigadzirwa zvepurasitiki zvisingaparare, izwi rekuti "purasitiki inoparara" rinowanikwa mu "Maonero Ekuwedzera Kusimbisa Plastic Pollution Control", "14th Five-Year Plan Plastic Mu "Pollution Control Action Plan" nemamwe magwaro, mabhizinesi nemabhizinesi atangawo kutsiva kushandiswa kwemapurasitiki anoparara.
Oxidative degradation yemapurasitiki inoreva kuwedzerwa kwephotosensitizers kana oxidation catalysts kumapurasitiki asina kuparara (akadai se polyethylene PE) kuti akurumidze kushatisa kwavo munzvimbo dzakajeka kana dzine oxygen.Nekudaro, zvigadzirwa zvayo zvekushatisa zvinosanganisira zvigadzirwa zvechisikigo senge kabhoni dhaidhirosi nemvura, pamwe nezvinowedzerwa senge microplastics uye plasticizers.Zvinowedzera zvinosvibisa nharaunda, uye zvidzidzo zvakawana kuti microplastics inogona kuvapo munharaunda kwenguva yakareba.Kwete izvozvo chete, microplastics inogona kutora zvinosvibisa kubva kune zvakatipoteredza, uye nekuunganidza kwenguva refu uye kumhanya kwekufamba muvhu repamusoro, ivo vanozopedzisira vasvibisa kuita microplastics kana kunyange nanoplastics ine diki diki saizi, kutamira kumvura yepasi, uye inogona kupinda mumunhu. muviri.
Mumakore achangopfuura, nyika zhinji nematunhu akarambidza kutenderera uye kushandiswa kwemapurasitiki anoora oxo.European Commission yakapasa "Directive (EU) 2019/904" muna Chikumi 2019, iyo inorambidza zviri pachena zvese oxidative degradation zvigadzirwa zvepurasitiki, zvinosanganisira zvekushandisa chete zvigadzirwa zvepurasitiki, uye yakaitwa muna Chikunguru 2021. Mutemo wakagamuchirwa neIceland muna Chikunguru 2020 unorambidza kuiswa pamusika wezvigadzirwa zvakagadzirwa nemapurasitiki zvinogona kuderedzwa neoxidation kana anonzi mapurasitiki eokisijeni, uye ichaitwa muna Chikunguru 2021. Mitemo (FOR-2020-12-18- 3200) yakatenderwa neNorwegian Ministry of Climate and Environment kurambidza oxo-inoshatisa zvigadzirwa zvepurasitiki uye zvimwe zvinoraswa zvepurasitiki zvigadzirwa zvakapihwa muna Ndira 2021 uye zvakatanga kushanda muna Chikunguru wegore rimwe chetero.
Muna Zvita 2020, Hainan yakaita zviri pamutemo "Mitemo paKurambidzwa kweZvisizvo Zvisingaparare Zvigadzirwa zvePlastiki muHainan Special Economic Zone".Plastics uye thermo-oxo-degradable plastics ane zvinhu zvepurasitiki zvakajairika.Izvi zvinoreva kuti mapurasitiki ane oxidatively degradable haachabvumirwi kushandiswa muHainan Province, uye Hainan yave purovhinzi yekutanga munyika kuita kurambidzwa kwepasirese kwepurasitiki (kusanganisira oxidatively degradable plastics).
Kuita kwaHainan kwekutanga kurambidza kuderedzwa kweoxidative yemapurasitiki kwakapa masangano mazhinji ekuchengetedza nharaunda mukana.Vakanganiswa neizvi, masangano matanhatu ekuchengetedza kwezvakatipoteredza akatanga chirongwa che "kurambidza kugadzirwa nekushandiswa kwemapurasitiki anoshatisa ane oxidatively", achidana kune dzimwe hurumende dzemuno muChina kuti dzitaure nezvekuita kwaHainan, kutarisana nekujekesa dambudziko remapurasitiki anokanganisa oxidatively, uye bvisa kukanganiswa kweoxidatively degradable mapurasitiki munyika yedu nekukurumidza sezvinobvira.Kukuvadza kune ecological nharaunda uye hutano.
No oxo-degradable mapurasitiki, chengetedza pasi redu.
Huya kuWorldChamp Enterprises, wakoECO zvigadzirwa mutengesi, mapiyona anoronga, kugadzira, uye kushandisa zvigadzirwa zvakasvibirira zvinotsiva zvechinyakare mapurasitiki zvinhu, kusanganisiramagirovhosi anogadzirwa nemafuta, bhegi rekubuda, bhegi rekutumira, bhegi rekutenga, bhegi remarara, bhegi rembwa, apron, nezvimwewo.
