Ongororo yakawana mabhegi achiri kukwanisa kutakura kutenga kunyangwe zvainzi zvakatipoteredza
Mabhegi epurasitiki anoti anogona kuparara anga achiri akasimba uye achikwanisa kutakura kutenga makore matatu mushure mekuratidzwa kune zvakasikwa, ongororo yakawana.
Tsvagiridzo kekutanga yakayedza mabhegi ane compostable, maviri mabhegi e biodegradable bhegi uye akajairwa mabhegi ekutakura mushure mekuratidzwa kwenguva refu kugungwa, mhepo uye pasi.Hapana kana masaga akaora zvizere munzvimbo dzese.
Iro compostable bhegi rinoratidza kuti rakafamba zviri nani pane rinodaidzwa kuti biodegradable bag.Sample yebhegi recompostable yanga yanyangarika zvachose mushure memwedzi mitatu iri munzvimbo yegungwa asi vaongorori vanoti basa rakawanda rinodiwa kuona kuti zvigadzirwa zvakaparara ndezvipi uye kufunga chero zvingangoitika kwezvakatipoteredza.
Pashure pemakore matatu mabhegi e“biodegradable” akanga avigwa muvhu negungwa akakwanisa kutakura kutenga.Iyo compostable bhegi yaivepo muvhu 27 mwedzi mushure mekuvigwa, asi payakaedzwa nekutenga haina kukwanisa kubata chero huremu pasina kubvarura.
Vatsvagiri vekuUniversity yePlymouth's International Marine Litter Research Unit vanoti ongororo iyi - yakaburitswa mupepanhau reEnvironmental Science and Technology - inomutsa mubvunzo wekuti maumbirwo anogona kuvimbwa nawo anogona kuvimbwa nawo kuti ape mwero wepamusoro wekuderera uye nekudaro mhinduro yechokwadi kune dambudziko remarara epurasitiki.
Imogen Napper, akatungamira chidzidzo ichi, akati:“Pashure pemakore matatu, ndakashamiswa zvikuru kuti mabhegi api naapi aigona kuchengeta mutoro wokutenga.Kuti mabhegi ebiodegradable akwanise kuita izvo zvakanyanyo shamisa.Ukaona chimwe chinhu chakanyorwa nenzira iyoyo, ndinofunga unobva wafunga kuti chichadzikisira nekukurumidza kupfuura mabhegi akajairwa.Asi, mushure memakore matatu angangoita, tsvagiridzo yedu inoratidza kuti zvingave zvisiri izvo. ”
Inenge hafu yepurasitiki inoraswa mushure mekushandiswa kumwe chete uye yakawanda inopera semarara.
Kunyangwe kuunzwa kwekubhadharisa mabhegi epurasitiki kuUK, masupamaketi achiri kugadzira mabhiriyoni gore rega rega.Akuongororwa kwepamusoro pemasupamaketi gumineGreenpeace yakaratidza kuti vaigadzira 1.1bn mabhegi epurasitiki anoshandiswa kamwe chete, epurasitiki 1.2bn anogadzira mabhegi emichero nemiriwo uye 958m anogona kushandiswa zvakare "mabhegi ehupenyu" pagore.
Chidzidzo chePlymouth chinoti muna 2010 zvakafungidzirwa kuti 98.6bn mabhegi epurasitiki anotakura akaiswa pamusika weEU uye anenge 100bn mamwe mabhegi epurasitiki akaiswa gore rega kubva.
Kuziva nezvedambudziko rekusvibiswa kwepurasitiki uye kukanganisa kwezvakatipoteredza kwakakonzera kukura kwezvinonzi biodegradable uye compostable sarudzo.
Tsvagiridzo iyi inoti zvimwe zvezvigadzirwa izvi zvinotengeswa padivi pezvirevo zvinoratidza kuti zvinogona "kudzokororwa kudzoka muzvisikwa nekukurumidza zvakanyanya kupfuura zvakajairika plastiki" kana "zvinomera-zvakavakirwa dzimwe nzira dzepurasitiki".
Asi Napper akati mhedzisiro yakaratidza kuti hapana rimwe remabhegi rinogona kuvimbwa naro kuratidza kuderera kwakanyanya mukati memakore matatu munzvimbo dzese."Saka hazvina kujeka kuti maoxo-biodegradable kana biodegradable formulations anopa mwero wepamusoro wekushata kuti ubatsire mukuderedza marara emugungwa, zvichienzaniswa nemabhegi akajairwa," tsvakurudzo yakawana.
Tsvagiridzo yakaratidza kuti nzira yekuraswa mabhegi ecompostable yaive yakakosha.Vanofanirwa kuoresa muhurongwa hwekuita manyowa kuburikidza nekuita kwezvipembenene zvinongoitika zvega.Asi chirevo chakataura kuti izvi zvinoda tsvina yakatsaurirwa kumarara inosanganiswa - iyo UK isina.
Vegware, iyo yakagadzira iyo compostable bhegi yakashandiswa mukutsvagisa, yakati chidzidzo ichi chiyeuchidzo chakakodzera nguva chekuti hapana zvinhu zvaive zvemashiripiti, uye zvinogona kungodzokororwa munzvimbo yayo chaiyo.
"Zvakakosha kuti unzwisise mutsauko uripo pakati pemazwi akadai se compostable, biodegradable uye (oxo) -degradable," akadaro mutauriri.“Kurasa chigadzirwa mumhoteredzo kuchiri kuita tsvina, kuita compost kana neimwe nzira.Kuviga hakusi kuita manyowa.Zvishandiso zvinogadzirwa zvinogona kuita manyowa nemamiriro mashanu akakosha - hutachiona, okisijeni, hunyoro, kudziya uye nguva. "
Mhando shanu dzakasiyana dzepurasitiki inotakura bhegi dzakaenzaniswa.Izvi zvaisanganisira mhando mbiri dzehomwe yeoxo-biodegradable bag, bhegi rimwechete rinogona kuparara, rimwe bhegi rinoita compostable, uye high-density polyethylene bag - bhegi repurasitiki rakajairika.
Chidzidzo ichi chakawana kushaikwa kwehumbowo hwakajeka hwekuti zvinhu zvinoora, oxo-biodegradable uye compostable zvinhu zvinopa mukana wezvakatipoteredza kupfuura mapurasitiki akajairwa, uye mukana wekupatsanurwa kuita microplastics wakakonzera kumwe kunetseka.
Mukuru webazi iri, Prof Richard Thompson, vanoti tsvakiridzo iyi yamutsa mibvunzo yekuti veruzhinji vari kurasika here.
“Isu tinoratidza pano kuti zvinhu zvakaedzwa hazvina kupa mukana wakafanana, wakavimbika uye wakakodzera mumamiriro emarara emugungwa, "akadaro.“Zvinondinetsa kuti zvinyorwa zvitsva izvi zvinopawo matambudziko mukudzokorodza.Chidzidzo chedu chinosimbisa kudiwa kwezviyero zvine chekuita nezvinhu zvinoparara, zvichinyatso tsanangura nzira yakakodzera yekurasa uye mwero wekuparara unogona kutarisirwa.
