Muna Ndira gore rapfuura, Mafungiro eKuwedzera Kusimbisa Plastic Pollution Control yakapihwa neNational Development and Reform Commission uye Ministry of Ecology and Environment yakanzi "yakasimba kwazvo epurasitiki muganhu munhoroondo". Beijing, Shanghai, Hainan nedzimwe nzvimbo dzakamhanyisa kuita kweiyo yeplastic muganho. Chengdu vhezheni ye "Iyo Yakasimba Plastic Restriction Order muNhoroondo"- "Chengdu Action Plan yekusimbisa Plastic Pollution Control" ichapindawo muhupenyu hwemunhu wese pamwe ne2021.
"Asi mwero wacho wati wedzerei, unonzwa uchinetsekana, uye hapana zano parizvino." Muyero wakataurwa naVaYang, uyo ari kuita basa rekugadzira zvigadzirwa zvepurasitiki, unoreva chiyero chemabhegi epurasitiki anoparara. Mukuwedzera kuna VaYang, vagari vazhinji vanovhiringidzika pamusoro peyero ye "plastic limit order". "Ini ndinotsigira zvakanyanya kuganhurwa kwepurasitiki, asi handizive kuti ndeipi bhegi repurasitiki rinoparara."
Ndeupi rudzi rwebhegi repurasitiki rinoparara, uye chiyero chinofanira kucherechedzwa? Mutori wenhau akabvunza nezve akakodzera zviyero uye akabvunzurudza masangano ekuyedza.

Mabhegi epurasitiki anoparara ane zviyero zvakasiyana, uye zvigadzirwa zvine handfeel yakasiyana
Mutori wenhau akashanyira saiti iyi ndokuona kuti zviyero zvemabhegi epurasitiki anoparara anoshandiswa nezvitoro zvikuru zvisingaenderane.
Iyo biodegradable purasitiki yekutenga bhegi inoshandiswa mufamilymart yakanyorwa neGB/T38082-2019. Sekureva kwemugadziri, iyi ndiyo chiyero chinoshandiswa zvakanyanya mumabhegi epurasitiki anoparara muindasitiri.
Nekudaro, mabhegi ekutenga epurasitiki anoshandiswa muzvitoro zveWOWO anongova nemazwi ekuti "mabhegi ekuchengetedza nharaunda anoshatisa", pasina kumaka zviyero zvekugadzira kana marudzi epurasitiki. Iri bhegi repurasitiki rinonzwa rakati siyanei nerefamilymart, rinonzwa kukora uye rine nzvimbo yakatsetseka.
Uye zvakare, chiyero pamabhegi epurasitiki emasupamaketi matatu ndeye Plastic Shopping Mabhegi (GB/T21661-2008). Mamwe mabhegi epurasitiki anoita chiyero ichi anodhindwa aine sirogani yekuti “bhegi rekudzivirira kwezvakatipoteredza” kuenda kumba”. Ko rudzi urwu rwepurasitiki bhegi rinoparara here? Vatengesi vakataura kuti haasi mabhegi epurasitiki anoparara, uye mashoko okuti "kuchengetedzwa kwezvakatipoteredza" akanyorwa mune tariro yokuti munhu wose anogona kuashandisa kakawanda.
Pamusoro pekushanyira Shangchao, mutori wenhau akaona munzvimbo yekutengesa muErxianqiao kuti kune marudzi maviri emabhegi epurasitiki akaparara anotengeswa pano. Imwe yakafanana neiri muWOWO chitoro, ine nzvimbo yakatsetseka, uye imwe yakafanana nebhegi repurasitiki rinoparara rinoshandiswa mufamilymart, rine huremu hwakareruka.

Shandisa zviyero zvakasiyana, uye zviyero zvinosiyana munzvimbo nenzvimbo
Mushure mekupinda "mabhegi epurasitiki anoshatisa" pawebhusaiti yekutenga, mutori wenhau akabvunza zvitoro zvishanu kana zvitanhatu zvine huwandu hwekutengesa, uye akadzidza kuti mabhegi epurasitiki akaparara anotengeswa pamhepo anosanganisira mapoka matatu: biodegradation, starch-based degradation uye kuomeswa kwemifananidzo.
Pakati pawo, mabhegi epurasitiki anoomeswa anowanzo kunzi akazara biodegradable mabhegi epurasitiki, uye chiyero chekushandisa ndeye GB/T38082-2019. Musanganiswa wePBAT+PLA nePBAT+PLA+ST unogamuchirwa, uye mwero wekuparara unopfuura 90%. Zvinhu zvakapfava, bhegi rinopenya, kushatiswa kwechisikigo, uye mutengo unodhura.
Starch-based inoshatisa mabhegi epurasitiki ane bio-based chibage starch ST30 inoshatisa zvinhu, uye chiyero chekushandisa ndeye GB/T38079-2019. ST30 yekudyara chibage starch musanganiswa inogamuchirwa, uye bio-based content i20% -50%. Zvinhu zvacho zvakapfava zvishoma, bhegi rine mukaka uye yero, iyo inogona kuvigwa uye yakaderedzwa, uye mutengo uri pakati nepakati.
Iyo photodegradable bhegi repurasitiki rakagadzirwa nephotodegradable mineral uye inorganic poda MD40, uye chiyero chekushandisa ndeye GB/T20197-2006. Iko kusanganiswa kwePE uye MD40 zvimedu zvinoparara zvinogamuchirwa, uye chiyero chekuora chinodarika makumi matatu muzana. Izvo zvinhu zvakaoma kubata, bhegi jena remukaka, rinogona kupiswa kuita upfu, kuvigwa uye foto-oxidized, uye mutengo unodhura uye unoshanda.
Kunze kwezviyero zvitatu zviri pamusoro, mutori wenhau haana kuona GB/T21661-2008 mumushumo wekuongorora wakapihwa nevatengesi.
Vamwe vatengesi vakati mitemo yakawanda yemunharaunda yakasiyana, zvichienderana nekwairi kushandiswa. “Biodegradation inowanzo shandiswa munzvimbo dziri mumahombekombe, uye inodiwa kuti iwane 100% kuparara kwemvura. Parizvino, Hainan inoda kuzara kwebiodegradation, uye kuderedzwa kwesitashi uye kuomeswa kwemifananidzo kunogona kushandiswa mune dzimwe nzvimbo.

Chiyero chakaburitsa pachena kuti chinomaka sei: "chimaka pachigadzirwa kana kurongedza kwekunze"
Zviyero zvemabhegi epurasitiki anoparara zvinoyevedza. Mipimo iri pamusoro apa inoshanda here? Mutori wenhau akabvunza nezve iyi nyaya muyedzo yenyika yakazara-zvinyorwa kuburitsa system uye ane hukama mawebhusaiti eindastiri. Kunze kwekuti "GB/T21661-2008 mabhegi epurasitiki ekutenga" akabviswa muna Zvita 31, 2020 uye akatsiviwa ne "GB/T 21661-2020 mabhegi epurasitiki ekutenga", mamwe ese mazinga aripo parizvino.
Izvo zvakakosha kucherechedza kuti GB/T 20197-2006 inotsanangura tsananguro, kupatsanura, kumaka uye kushatisa kuita zvinodiwa zvemapurasitiki anoparara. Zvinoenderana nechiyero ichi, pasi pezvakatsanangurwa mamiriro ezvakatipoteredza, mushure menguva yenguva uye kusanganisira nhanho imwe kana anopfuura, chimiro chemakemikari yezvinhu chinoshanduka zvakanyanya uye zvimwe zvivakwa zvicharasika, kana mapurasitiki achaputswa kuita mapurasitiki akaora. Zvinoenderana nedhizaini yayo, nzira dzekupedzisira dzekushatisa dzemapurasitiki anoparara anosanganisira mapurasitiki anoodza, mapurasitiki anogadzirwa, mapurasitiki anogona kuomeswa uye thermooxidative inoparara.
Panguva imwecheteyo, zvinokurudzirwa mune iyi chiyero kuti kana uchishandisa zviratidzo zvezvakaora zvigadzirwa zvepurasitiki, zvinofanirwa kucherechedzwa pane zvigadzirwa kana ekunze kurongedza. Iyo fotodegradable polypropylene epurasitiki sheet inogadzirwa zvinoenderana neiyi chiyero ine 15% yemamineral poda uye 25% yegirazi faibha nekuwanda, uye 5% photosensitizer inowedzerwa. Kureba, hupamhi uye ukobvu i500mm, 1000mm uye 2mm zvakateerana, iyo inoratidzwa seGB/T20197/ photodegradable plastic plastic PP-(GF25+MD15)DPA5.
