Plastiki yakakosha zvekuti hatigone kurarama tisina.Inotanga kuwanikwa mu850 muChirungu.Anopfuura makore 100, iri kwese kwakatitenderedza pasirese.Kubva pamapakeji ezvekudya uye chengetedzo yemazuva ese kusvika kumakemikari nemishonga kurongedza, tinoishandisa kwese kwese.Ndiwo anonyanya kuwanikwa zvinhu muhupenyu hwedu hwezuva nezuva.Isu tinocherekedza zvakanakira mapurasitiki ayo nekuzviparadzanisa kwakanaka, uye kuoma, zvakachipa uye zvakanaka kugadzikana.Sezvo zvinotiunzira kurerukirwa kwakadaro, asi zvinokonzeresa matambudziko mazhinji ezvakatipoteredza.

 

  1. Mhando dzese dzepurasitiki dzakaoma kudzikisira zvakasikwa.Kunoita kuti marara awedzere panyika.Kunyanya kukanganisa maguta makuru kushandiswa kwevhu zvakare kuchasvibisa nyika.
  2. Iyo yegungwa ecosystem ichakanganiswa.Kana mapurasitiki akaenda kugungwa, achaita kuti mhuka dzemugungwa dzitore sechikafu nekukanganisa uye kukonzera chepfu uye asphyxia.
  3. Kupisa mapurasitiki kuchakonzera kusvibiswa kwemhepo.

 

Isu tinofanirwa kudzokorodza mapurasitiki nekodhi yekuzivikanwa resin.Kusiyana kwepurasitiki maitiro akasiyana.Uye kazhinji kudzokororwa kwemarara tinounganidza iwo mapurasitiki pamwechete.Ibasa rakaoma kwatiri kuronga mapurasitiki.Kazhinji isu tinofanirwa kuronga mapurasitiki nemanyore uye nemichina yakangwara.Mushure mezvo ichapwanyika uye yobva yageza uye yooma.Mushure mekuoma inogona kupetwa kune inotevera kugadzirwa, sengeHDPE mabhodhorokugeza inopisa uyepelletizing muchina.Iyo yakagezwa yakaoma zvinhu inogona kushandiswa zvakananga kushandiswa kwekugadzira, senge inopisa yakagezwa PET maflakes kune POY fiber.
