Imininingwane ewusizo epulasitiki

El upulasitiki Namuhla kungenye yezinto ezisetshenziswa kakhulu ezinkulungwaneni zezinhlelo zokusebenza kwansuku zonke nasembonini amashumi eminyaka ambalwa.

Ipulasitiki yadalwa cishe ngonyaka we-1860, kepha ukusetshenziswa kwayo kwaqala ngawo-1930.

Amapulasitiki okwenziwa anezici ezenze ukuthi le nto ithandwe: kushibhile ukukhiqiza, inamanani aphansi, ayinamanzi, iyaguquguquka, iyavikela ngogesi, ayizweli futhi iyavumelana nazo zonke izinhlobo zokusetshenziswa.

Ukukhiqizwa kwepulasitiki kungcolisa kakhulu ikakhulukazi uma kushiswa, ezinye izinhlobo zepulasitiki kulula ukuzisebenzisa kabusha kodwa ezinye.

  • Ukusetshenziswa kweplastiki emhlabeni jikelele ngo-2010 kwakungamathani ayizigidi ezingama-250 futhi kuyaqhubeka nokwanda.
  • Ipulasitiki ejwayelekile ithatha phakathi kuka-100, 500 kuya eminyakeni eyi-1000 ukwehlisa isithunzi kuye ngohlobo lwezinto ezisetshenziswayo lapho zenziwa.
  • Ukusetshenziswa kwepulasitiki kwendabuko i-petroleum nemikhiqizo evela ekwakhiweni kwayo ngakho kungcolisa kakhulu, ngaphezu kwalokho okuningi kusetshenzisiwe amandla ekuchazeni kwayo.
  • Imfucuza yaseplastiki imele udoti ongu-60 kuya ku-80% otholakala olwandle nasemabhishi emhlabeni jikelele.
  • Kulinganiselwa ukuthi kudliwa izikhwama zepulasitiki eziyizigidi eziyizinkulungwane unyaka nonyaka emhlabeni, bese kuthi iningi lazo liphendulwe udoti, ngoba okubolayo yilawo manzi.
  • Kunezinhlobonhlobo zepulasitiki ezisetshenziswa kakhulu kuzo zonke izinhlobo zezinto. Ezinye zezinto ezisetshenziswa kakhulu yiPolystyrene, iPolypropylene, iPolyurethane, i-PVC, i-PET, i-polyamide, phakathi kwabanye.
  • Amapulasitiki endabuko angaba nokuthungwa okuhlukile, ubulukhuni nesimo somzimba ngoba kungaba yigwebu, impahla eqinile, ithambile, njll.

Ekuphetheni, ipulasitiki yake yathathwa njengezinto zesimanje ezixazulula izinkinga ezahlukahlukene futhi inezinkulungwane zezicelo. Kepha ngokudlula kwamashumi eminyaka linikeze izinzuzo kepha futhi likhiqiza ukungcola okukhulu futhi lenza udoti omningi emhlabeni wonke.

Njengamanje, amapulasitiki endabuko awasabhekwa njengempahla enhle kakhulu ngenxa yemiphumela yawo empilweni yabantu nasemvelweni.
