Izikhwama zepulasitiki ezibolayo zisengakwazi ukuthwala ukuthenga eminyakeni emithathu ngemuva kokushiywa endaweni yemvelo.
Izinto ezinhlanu zezikhwama zepulasitiki ezitholwe ezitolo zase-UK zahlolwa ukubona ukuthi kwenzekani kuzo ezindaweni lapho zingavela khona uma zilahliwe.
Zonke zahlakazeka zaba yizicucu ngemva kokuchayeka emoyeni izinyanga eziyisishiyagalolunye.
Kodwa ngemva kweminyaka engaphezu kwemithathu emhlabathini noma olwandle, izinto ezintathu, kuhlanganise nezikhwama ezibolayo, zazingaphelele.
Izikhwama ezivundisiwe zitholakale zinobungane kancane emvelweni - okungenani olwandle.
Ngemva kwezinyanga ezintathu endaweni yasolwandle base benyamalele, kodwa base bengase batholakale emhlabathini ngemva kwezinyanga ezingu-27.
Ososayensi eNyuvesi yasePlymouth bahlola izinto ezihlukene ngezikhathi ezithile ukuze babone ukuthi zaphuka kanjani.
Bathi lolu cwaningo luphakamise imibuzo mayelana nemikhiqizo ebolayo edayiswa abathengi njengenye yezindlela ezihlukile kunopulasitiki ongasetshenziswa kabusha.
"Ukuze izikhwama ezibolayo zikwazi ukwenza lokho kwakumangalisa kakhulu," kusho u-Imogen Napper, owayehola ucwaningo.
“Uma ubona into ebhalwe ngaleyo ndlela ngicabanga ukuthi uvele ucabange ukuthi izokwehla ngokushesha kunezikhwama ezijwayelekile.
"Kodwa ngemuva kweminyaka emithathu okungenani, ucwaningo lwethu lukhombisa ukuthi lokho kungenzeka kungabi njalo."
Biodegradable v compostable
Uma into ibola ibola ingabhidlizwa yizinto eziphilayo ezifana namagciwane kanye nesikhunta.
Cabanga ngesithelo esisele otshanini - sinikeze isikhathi futhi sizobonakala sesinyamalele ngokuphelele.Empeleni nje “igaywe” ama-microorganisms.
Kwenzeka ezintweni zemvelo ngaphandle kokungenelela komuntu okunikezwe izimo ezifanele - njengezinga lokushisa nokutholakala komoyampilo.
Ukwenza umquba yinto efanayo, kodwa kulawulwa abantu ukwenza inqubo isheshe.
I-Co-op'sizikhwama zepulasitiki ezivundisiweenzelwe ukumosha ukudla, futhi ukuze afakwe esigabeni esivundisiwe kufanele aphuke engakapheli amasonto ayi-12 ngaphansi kwezimo ezithile.
Ososayensi basePlymouth baphinde babuza ukuthi izinto ezibolayo ezingaboli zisebenza kanjani njengesixazululo sesikhathi eside senkinga yamapulasitiki asetshenziswa kanye.
“Lolu cwaningo luphakamisa imibuzo eminingi mayelana nokuthi umphakathi ungalindelani uma ubona into ebhalwe ukuthi i-biodegradable.
“Sikhombisa lapha ukuthi izinto ezihloliwe azizange ziveze inzuzo engaguquki, enokwethenjelwa nefanelekile kumongo kadoti wasolwandle.
“Kuyangikhathaza ukuthi lezi zincwadi zamanoveli nazo zinezinselelo ekusetshenzisweni kabusha,” kusho uSolwazi Richard Thompson, inhloko ye-International Marine Litter Research.
Ocwaningweni, ososayensi bacaphuna umbiko we-European Commission ka-2013 owawuphakamisa ukuthi zilinganiselwa ku-100 billion izikhwama zepulasitiki ezikhishwa unyaka ngamunye.
Ohulumeni abahlukahlukene, kubandakanya ne-UK, selokhu bethula izindlela ezifana nezimali zokunciphisa inani elisetshenziswayo.
