Mumakore achangopfuura, kusimudzira kwave kutarisisa kwakakosha kune vatengi nemaindasitiri zvakafanana. Nekunetseka kuri kukura pamusoro pekusvibiswa kwepurasitiki, mabhegi e polyethylene (PE) auya pasi pekuongororwa. Muchinyorwa chino, isu tichaongorora eco-hushamwari hwemabhegi ePE, kukanganisa kwavo kwezvakatipoteredza, uye kana vachigona kutorwa sesarudzo inoenderera.
Chii chinonzi PE Bag?
Mabhegi ePE anogadzirwa kubva ku polyethylene, ipurasitiki inonyanya kushandiswa pasi rose. Ivo vanozivikanwa nekusimba kwavo, kuchinjika, uye kuramba hunyoro, zvichiita kuti vazivikanwe mukurongedza, kutenga, uye kuchengetedza. Mabhegi ePE anouya nenzira dzakasiyana siyana, anosanganisira ziplock mabhegi, mabhegi egirosari, uye zvekurongedza zvinhu, uye anofarirwa nekuda kwekuita kwavo mutengo uye nyore.
Environmental Impact yePE Bags
Kukanganisa kwezvakatipoteredza kwemabhegi ePE kunotanga nekugadzirwa kwavo. Polyethylene inotorwa kubva kumafuta asingadzokerikezve, kunyanya crude oiri kana gasi rechisikigo. Maitiro ekugadzira anoshandisa simba rakakosha uye anokonzeresa kuburitsa kabhoni, zvichikonzera kudziya kwepasirese. Nekudaro, mabhegi ePE akareruka uye anoda zvinhu zvishoma pane dzimwe nzira dzakawanda, kuderedza kushandiswa kwesimba rose zvichienzaniswa nekukora, zvigadzirwa zvinorema senge mabhegi emapepa kana mabhegi emachira anogona kushandiswa zvakare.
Decomposition Rate uye Ecosystem Impact
Chimwe chezvakanyanya kunetseka nemabhegi ePE kurarama kwavo kwenguva refu munzvimbo. PE mabhegi haakurumidzi kuora; mumarashi, anogona kutora mazana emakore kuti aputsike nekuda kwekushaikwa kwechiedza chezuva uye oxygen. Munzvimbo dzechisikigo, dzakadai semakungwa nemasango, dzinogona kupatsanuka kuita microplastics, zvichiisa njodzi kumhuka dzesango dzinogona kumedza kana kunyura mune izvo. Uku kuderera kunononoka kunokonzera kusvibiswa kwepurasitiki, iyo inyaya huru yezvakatipoteredza.
Kugadziriswazve kwePE Mabhegi
PE mabhegi anogona kushandiswazve, asi mwero wekudzokorodza wakaderera kana uchienzaniswa nezvimwe zvinhu. Mapurogiramu mazhinji eku curbside ekudzokorodza haagamuchire mabhegi ePE nekuda kwemaitiro avo ekuvharisa michina yekuronga. Nekudaro, zvitoro zvakawanda nenzvimbo dzakanyanya kudzokorodza dzinogamuchira mabhegi aya kuti adzokororwe, kwaanogona kudzoserwa kuita zvigadzirwa zvepurasitiki zvitsva zvakaita semapuranga akaumbwa kana mabhegi matsva. Kuwedzera kuziva uye kuvandudzwa kwezvivakwa zvekudzokorodza zvinogona kuderedza zvakanyanya mutoro wezvakatipoteredza wemabhegi ePE.
Mabhegi ePE Anofananidzwa Sei Nemamwe Mabhegi?
Kana tichienzanisa kukanganiswa kwezvakatipoteredza kwemabhegi ePE kune dzimwe nzira senge bepa kana mamwe marudzi epurasitiki, mhedzisiro inosanganiswa. Mabhegi emapepa, nepo biodegradable, inoda simba rakawanda uye mvura kugadzira. Zvidzidzo zvinoratidza kuti mabhegi emapepa ane yakakwira kabhoni tsoka nekuda kwezviwanikwa zvinodiwa pakurima kwemiti, kugadzira, uye kutakura. Kune rimwe divi, mabhegi epurasitiki akakora anogona kushandiswa zvakare (anowanzo gadzirwa kubva ku polypropylene) uye mabhegi emachira anoda kushandiswa kwakawanda kudzikamisa maitiro avo epamusoro ekugadzira. Mabhegi ePE, kunyangwe akadzikira, ane diki yekutanga tsoka asi haana eco-hushamwari kana akaguma ari munharaunda pane kuti ashandiswezve.
Tsvakurudzo uye Nhamba
Chidzidzo che2018 neDanish Ministry of Environment uye Chikafu chakaenzanisa kuongororwa kwehupenyu hwemhando dzakasiyana dzemabhegi ekutenga. Yakaona kuti PE mabhegi aive neyakadzikira kwezvakatipoteredza maererano nekushandiswa kwemvura, kushandiswa kwesimba, uye kuburitsa gasi regreenhouse kana rakashandiswazve kakawanda kana kudzokororwa. Zvisinei, chidzidzo chacho chakaratidzawo kukosha kwekurasa kwakakodzera kuderedza njodzi yekusvibiswa. Idzi data rinoratidza kuti nepo mabhegi ePE asiri zvachose asina mutengo wezvakatipoteredza, anogona kuve sarudzo yakatsiga pane dzimwe nzira mune mamwe mamiriro, kunyanya kana akashandiswazve.
Mhedziso
PE mabhegi, senge chero chigadzirwa chepurasitiki, ane zvakatipoteredza zvakanakira uye zvakaipira. Mutengo wavo wakaderera wekugadzira, kudzokorodza, uye kuita zvakasiyana-siyana zvinoita kuti zvive zvakakosha, asi nguva yavo yekuparara kwenguva refu uye mupiro ungangoita mukusvibiswa kwepurasitiki zvinonetsa. Nekuwedzera mareti ekudzokorodza, kukurudzira kuraswa zvine mutoro, uye kusarudza eco-inoshamwaridzika dzimwe nzira pazvinogoneka, vatengi vanogona kubatsira kudzikisira kukanganisa kwezvakatipoteredza kwemabhegi ePE. Sezvinoita chero chinhu, kiyi yekugarisa iri mukunzwisisa kutenderera kwehupenyu hwakazara uye kuita sarudzo dzine ruzivo.
Kuti uwane rumwe ruzivo nezve kukanganiswa kwezvakatipoteredza kwepurasitiki uye maitiro ekudzikisa tsvina yepurasitiki, funga kuverenga zviwanikwa kubva kuEnvironmental Protection Agency.
