Ipulasitiki iyinye yezinto ezingenakuphikwa kakhulu empilweni yanamuhla, ngenxa yezakhiwo zayo ezizinzile nezomakhemikhali. Ithola uhlelo lokusebenza olusakazekile ekupakisheni, i-catering, impahla yasekhaya, ezolimo, nezinye izimboni ezahlukahlukene.
Lapho ulandela umlando wokuziphendukela kwemvelo kwepulasitiki, izikhwama zepulasitiki zidlala indima ebaluleke kakhulu. Ngo-1965, inkampani yaseSweden Company Compleplast enelungelo lobunikazi futhi yathola izikhwama zepulasitiki zasePolyethylene emakethe, zithola ukuthandwa ngokushesha eYurophu futhi zibuyise esikhundleni sezikhwama zamaphepha nezindwangu.
Ngokwemininingwane evela kuhlelo lweNhlangano YeziNational Nations, ngaphakathi kwenkathi engaphansi kweminyaka engu-15, ngo-1979, izikhwama zepulasitiki zithambekeze ama-80% e-European Bagging Market Share. Kamuva, babumba ngokushesha ukubusa phezu kwemakethe yokubhaja komhlaba yonke. Ekupheleni kuka-2020, inani lemakethe lomhlaba wonke lezikhwama zepulasitiki ezidlula ama- $ 300 billion, njengoba kuboniswe yi-GRAD View Research Data.
Kodwa-ke, kanye nokusetshenziswa kabanzi kwezikhwama zepulasitiki, ukukhathazeka kwemvelo kwaqala ukuvela ngezinga elikhulu. Ngo-1997, kwatholakala indawo kadoti kadoti wePacific, ngokuyinhloko okubandakanya imfucuza yepulasitiki elahla olwandle, kufaka phakathi amabhodlela epulasitiki nezikhwama.
Ihambelana nenani lemakethe eliyizigidi eziyizinkulungwane ezingama-300, isitoko semfucuza yepulasitiki olwandle sami emathangeni ayizigidi ezingama-150 ezandulela amathani angama-200, futhi sizokwanda ngamathani ayizigidi eziyi-11 ngonyaka.
Noma kunjalo, amapulasithi endabuko, ngenxa yokusetshenziswa kwawo okubanzi kanye nezinto ezithandekayo zomzimba nezamakhemikhali zokusebenzisa izicelo eziningi, okuhambisana namandla okukhiqiza nezinzuzo zezindleko, zibonisa inselelo yokufaka esikhundleni kalula.
Ngakho-ke, izikhwama zepulasitiki ze-biodegradable zinezakhiwo ezibalulekile zomzimba nezamakhemikhali ezifana nezimpawu zendabuko, zivumela uhlelo lwazo ezimweni zokusetshenziswa kwepulasitiki eziningi. Ngaphezu kwalokho, badelela ngokushesha ngaphansi kwezimo zemvelo, benciphisa ukungcoliswa. Ngenxa yalokho, izikhwama zepulasitiki ze-biodegramable zingabhekwa njengesisombululo esifanele njengamanje.
Kodwa-ke, ukuguqulwa kusuka kudala kuya kokusha kuvame ukuba yinqubo emangalisayo, ikakhulukazi lapho kubandakanya ukufaka okunye esikhundleni sendabuko egxilile kwendabuko, okubusa izimboni eziningi. Abatshalizimali abangayazi nale makethe bangahle babambe ukungabaza mayelana nokusizakala kwamapulasitiki angathandeki.
Ukuvela kanye nokuthuthukiswa komqondo wokuvikelwa kwemvelo Isiqu esidingayo ukubhekana nokunciphisa ukungcoliswa kwemvelo. Izimboni ezinkulu ziqale ukwamukela umqondo wokusimama kwemvelo, kanti imboni yezikhwama zepulasitiki ayifani.
