SINGAPORE: Unogona kufunga kuti kuchinja kubva kune imwe chete-kushandisa mapurasitiki kune biodegradable epurasitiki dzimwe nzira kwakanakira zvakatipoteredza asi muSingapore, hapana "zvinobudirira misiyano", nyanzvi dzakati.
Vanowanzo guma munzvimbo imwechete - the incinerator, akadaro Associate Purofesa Tong Yen Wah kubva kuDhipatimendi reKemikari uye Biomolecular Engineering paNational University of Singapore (NUS).
Biodegradable plastiki tsvina inoita mutsauko kune zvakatipoteredza chete kana yavigwa mumarara, akawedzera.
“Mumamiriro ezvinhu aya, mabhegi epurasitiki aya anogona kuderera nekukurumidza kana zvichienzaniswa nesaga re polyethylene plastic bag uye haazokanganisa nharaunda zvakanyanya.Pakazere kuSingapore, zvingatonyanya kudhura kupisa mapurasitiki anogona kuparara,” akadaro Assoc Prof Tong.Akatsanangura kuti izvi imhaka yekuti dzimwe nzira dze biodegradable dzinotora zviwanikwa zvakawanda kugadzira, izvo zvinoita kuti dzidhure.
Mafungiro aya anoenderana nezvakataurwa naDr Amy Khor, Gurukota reNyika reZvemamiriro ekunze neMvura muParamende muna Nyamavhuvhu - kuti ongororo yehupenyu hwemabhegi anotakura anotakura uye anoraswa neNational Environment Agency (NEA) akawana kuti kutsiva. mapurasitiki ane mamwe marudzi e-single-use kurongedza zvinhu "hazvina hazvo nani kune zvakatipoteredza".
“MuSingapore, marara anopiswa uye haasiyirwi mumarashi kuti ashatise.Izvi zvinoreva kuti zviwanikwa zvinodikanwa zvemabhegi anoomeswa oxo akafanana neaya emabhegi epurasitiki, uye anewo maitiro akafanana ezvakatipoteredza kana apiswa.
"Uyezve, mabhegi anokanganisa oxo anogona kukanganisa nzira yekudzokorodza kana yakasanganiswa nemapurasitiki akajairwa," akadaro NEA kudzidza.
Oxo-anoora mapurasitiki anokurumidza kupatsanurwa kuita zvidimbu zvidiki uye zvidiki, zvinodaidzwa kuti microplastics, asi usapunzike pachikamu chemolecular kana polymer senge biodegradable uye compostable plastiki.
Iyo inoguma microplastics inosiiwa munharaunda nekusingaperi kusvika ivo pakupedzisira vaputsa zvizere.
iye European Union (EU) yakatofunga muna Kurume kurambidza zvinhu zvakagadzirwa nepurasitiki ine oxo-inoshatisa pamwe nekurambidzwa kwekushandisa mapurasitiki chete.
Mukuita sarudzo, EU yakati oxo-yakaora purasitiki "haiite zvakanaka biodegrade uye nekudaro inopa kusvibiswa kwemicroplastic munharaunda".
