Plastiki pasina mubvunzo ndechimwe chezvinhu zvakatekeshera muhupenyu hwazvino, nekuda kwekugadzikana kwayo kwemuviri nemakemikari zvinhu. Inowana kushandiswa kwakapararira mukurongedza, chikafu, midziyo yemumba, zvekurima, uye mamwe maindasitiri akasiyana.
Kana uchitsvaga nhoroondo yekushanduka kwepurasitiki, mabhegi epurasitiki anoita basa rakakosha. Muna 1965, kambani yeSweden Celloplast yakaita patent uye yakaunza polyethylene mabhegi epurasitiki kumusika, nekukurumidza kuwana mukurumbira muEurope uye kutsiva mapepa nemabhegi emachira.
Zvinoenderana nedata kubva kuUnited Nations Environment Programme, mukati menguva isingasviki makore gumi nemashanu, pakazosvika 1979, mabhegi epurasitiki akange atora inoshamisa 80% yemusika weEuropean bagging. Zvadaro, vakakurumidza kusimbisa hutongi pamusoro pemusika wepasi rose webhegi. Pakupera kwa2020, kukosha kwemusika wepasi rose kwemabhegi epurasitiki kwakapfuura madhora mazana matatu emadhora, sezvakaratidzwa neGrand View Research data.
Zvisinei, pamwe chete nekushandiswa kwakapararira kwehombodo dzepurasitiki, zvinetso zvezvakatipoteredza zvakatanga kubuda pamwero mukuru. Muna 1997, Pacific Garbage Patch yakawanikwa, kunyanya inosanganisira tsvina yepurasitiki yakakandwa mugungwa, kusanganisira mabhodhoro epurasitiki nemabhegi.
Zvichienderana neiyo $300 bhiriyoni yemusika kukosha, kuunganidzwa kwemarara epurasitiki mugungwa kwakamira pakukatyamadza kwemamiriyoni zana nemakumi mashanu ematani pakupera kwa2020, uye kuchawedzera nematani gumi nerimwe pagore mushure meizvozvo.
Zvakangodaro, mapurasitiki echinyakare, nekuda kwekushandisa kwawo kwakakura uye kunaka kwemuviri uye makemikari zvimiro kune akawanda maapplication, akabatanidzwa nehunyanzvi hwekugadzira uye mutengo wakanakira, zvinoratidza zvinonetsa kutsiva nyore.
Naizvozvo, mabhegi epurasitiki anoodza ane akakosha emuviri uye makemikari zvimiro zvakafanana nemapurasitiki echinyakare, achibvumira kushandiswa kwawo mune mazhinji aripo ekushandisa epurasitiki mamiriro. Uyezve, vanoderedza nokukurumidza pasi pemamiriro echisikigo, kuderedza kusvibiswa. Nekuda kweizvozvo, biodegradable epurasitiki mabhegi anogona kutorwa seyakanyanya mhinduro parizvino.
Nekudaro, shanduko kubva kune yekare kuenda kune itsva kazhinji inzira inoshamisa, kunyanya kana ichisanganisira kutsiva akadzika midzi mapurasitiki, ayo anotonga maindasitiri mazhinji. Vanoisa mari vasina kujairana nemusika uyu vanogona kuve nekusahadzika nezvekukwanisika kwemapurasitiki anoora.
Kubuda nekusimudzirwa kwepfungwa yekuchengetedzwa kwezvakatipoteredza kunobva pakudiwa kwekugadzirisa uye kuderedza kusvibiswa kwezvakatipoteredza. Maindasitiri makuru atanga kugamuchira iyo pfungwa yekuchengetedzeka kwezvakatipoteredza, uye indasitiri yemabhegi epurasitiki ndizvowo.
