Lingaliro la kuyika kwa biodegradable ngati njira yokhazikika limatha kumveka bwino m'lingaliro koma yankho la vuto lathu la pulasitiki lili ndi mbali yakuda ndipo limabweretsa zovuta.

Biodegradable ndi compostable monga mawu nthawi zambiri amagwiritsidwa ntchito mosinthana kapena kusokonezedwa wina ndi mzake.Iwo, komabe, ndi osiyana kwambiri momwe zinthu zimawonongera komanso malamulo omwe amawongolera.Miyezo yomwe imayang'anira ngati zoyikapo kapena zopangidwa ndi kompositi ndizokhwima komanso zofunikira koma izi sizili m'malo mwazinthu zomwe zimatha kuwonongeka ndi biodegradable, zomwe ndizovuta kwambiri.

Anthu akaona mawu akuti biodegradable pakuyika pamakhala malingaliro oti akusankha njira yomwe ili yabwino kwa chilengedwe, poganiza kuti zotengerazo zidzawonongeka popanda kukhudzidwa.Komabe, zinthu zomwe zimatha kuwonongeka ndi biodegradable nthawi zambiri zimatenga zaka kuti ziwonongeke, ndipo m'malo ena siziwonongeka nkomwe.

Nthawi zambiri, mapulasitiki owonongeka amawonongeka kukhala ma microplastics, omwe ndi aang'ono kwambiri moti sangathe kutsukidwa mokwanira.Ma microplastics amenewa amasakanikirana ndi chilengedwe ndipo amadyedwa ndi zamoyo za m'nyanja za m'nyanja kapena zinyama zina pamtunda ndipo zimathera m'mphepete mwa nyanja kapena m'madzi athu.Tinthu tating'onoting'ono tapulasitiki timeneti titha kutenga zaka mazana kapena masauzande kuti tiwonongeke ndikuwononga kwambiri pakadali pano.

Popanda malamulo okhwima omwe amazungulira zinthu zopangidwa ndi compostable mafunso amawuka omwe angaganizidwe kuti ndi owopsa.Mwachitsanzo, ndi mulingo wotani wa kuwonongeka komwe kumapanga chinthu chowonongeka ndi biodegradable?Ndipo popanda kuwongolera momveka bwino tingadziwe bwanji ngati mankhwala oopsa akuphatikizidwa mu kapangidwe kake kamene kamalowa m'chilengedwe pamene mankhwalawo akusweka?

Popitiriza kufufuza mayankho okhazikika pamapakedwe, makamaka mapulasitiki apulasitiki, kuyang'ana pa mayankho omwe kusweka kumabwera ndi kufunikira kosanthula ndikumvetsetsa zomwe zatsala pomwe mankhwalawo akuwonongeka.

Popanda malamulo okhwima omwe amatsogolera zomwe zimayikidwa muzoyikamo zowonongeka ndi momwe zimagwiritsidwira ntchito kuti zilole kuwonongeka koyenera, tiyenera kukayikira ngati ndi njira yabwino pazochitika zathu zamakono.

Mpaka titha kuwonetsa kuti zoyikapo zowononga zachilengedwe sizikuwononga chilengedwe, tiyenera kuyang'ana kwambiri kupeza njira zobwezeretsanso ndikugwiritsanso ntchito mapaketi apulasitiki athunthu.
