Kutsvaga Sustainable Solutions: Biodegradable kana Recyclable Plastics?

Kusvibiswa kwepurasitiki kunokonzeresa njodzi kunharaunda yedu, nematani anopfuura mabhiriyoni mapfumbamwe epurasitiki akagadzirwa kubva kuma1950s, uye anoshamisa 8.3 miriyoni matani anopera mumakungwa edu pagore.Zvisinei nekuedza kwepasi rose, 9% chete yepurasitiki inodzokororwa, zvichisiya ruzhinji kusvibisa magariro edu kana kugara mumarara kwemazana emakore.

Chimwe chakanyanya kukonzeresa dambudziko iri inyaya yekuwanda kwemidziyo yepurasitiki inoshandiswa kamwe chete semabhegi epurasitiki.Aya mabhegi, anoshandiswa kweavhareji yemaminetsi gumi nemaviri chete, anosimudzira kuvimba kwedu nemapurasitiki anoraswa.Maitiro avo ekuora anogona kutora makore anopfuura 500, achiburitsa microplastics inokuvadza munzvimbo.

 

Nekudaro, pakati pezvinetso izvi, biodegradable mapurasitiki anopa mhinduro inovimbisa.Yakagadzirwa kubva ku20% kana zvimwe zvinogonekazve, bio-plastiki inopa mukana wekudzikisa kutsamira kwedu pamafuta emafuta uye kuderedza kabhoni tsoka yedu.PLA, inotorwa kubva muzvirimwa zvakaita sechibage starch, uye PHA, inogadzirwa netupukanana, ndiwo maviri emhando dzekutanga dzebio-plastiki ane mashandiro akasiyana.

Nepo biodegradable mapurasitiki achipa imwe eco-inoshamwaridzika imwe nzira, zvakakosha kuti titarise maitiro avo ekugadzira.Kugadziriswa kwemakemikari uye maitiro ekurima ane chekuita nekugadzirwa kwebioplastic anogona kubatsira mukusvibisa uye nyaya dzekushandisa ivhu.Pamusoro pezvo, zvivakwa zvekurasa zvakafanira zvebio-plastiki zvinoramba zvakaganhurirwa, zvichiratidza kukosha kwemaitiro akakwana ekugadzirisa marara.

Kune rimwe divi, mapurasitiki anogona kudzokororwa anopa mhinduro inomanikidza ine yakaratidza kushanda.Nekusimudzira kudzokorodza nekudyara muzvivakwa kuti zvitsigire, tinogona kutsausa marara epurasitiki kubva mumarara uye kuderedza kukanganisa kwedu kwezvakatipoteredza.Nepo mapurasitiki anogona kucheneswa achiratidza chivimbiso, shanduko yakananga kuhupfumi hwakatenderedzwa, uko zvinhu zvinoshandiswazve nekudzokororwa, zvinogona kupa mhinduro yakasimba yenguva refu kudambudziko rekusvibiswa kwepurasitiki.
