3. Mutengi nyore
Sezvo vatengi vazhinji vachirarama hupenyu hunowedzera kubatikana uye hwakaoma, havana nguva yekutanga kubika kubva pakutanga, asi sarudza nzira yekudya iri nyore panzvimbo.Wakagadzirira kudya zvokudya pamwe cheteitsva flexible packagingvave chigadzirwa chinofarirwa nekushandisa zvizere maitiro azvino emagariro nehupfumi.
Panosvika 2020, kana zvichienzaniswa nezvigadzirwa zvekurima zvisina kurongedzerwa, kudyiwa kwenyama nyowani, hove nehuku kuchawedzera nekukurumidza.Iyi maitiro imhaka yekuda kwevatengi kwemhinduro dziri nyore uye kutonga kuri kukura kwemasupamaketi makuru anogona kupa chikafu chakaputirwa nehupenyu hurefu hwesherufu.
Mumakore gumi apfuura, nehuwandu huri kuwedzera hwezvitoro zvikuru uye hypermarkets, kunyanya misika iri kusimukira, uye kuwedzera kuri kuda kwevatengi kune zvigadzirwa zviri nyore sekubika, pre-simmering kana kufanocheka, kushandiswa kwechikafu chefiriji kwakawedzera.Kukura kwezvigadzirwa zve-pre-cut uye yakakwirira-yekupedzisira nhepfenyuro yakasimudzira kukura kweMAP kurongedza kudiwa.Kudiwa kwechikafu chakaomeswa nechando kunofambiswawo neakasiyana echikafu chekukurumidza, pasta nyowani, chikafu chemugungwa uye nyama, uye chimiro chekudya chiri nyore, chinotengwa nevatengi vanoziva nguva.
4. Biological derivation uye biodegradation tekinoroji
Mumakore mashoma apfuura, zvakawanda zvitsva zvigadzirwa zvebio basedpurasitiki kurongedzavabuda.Sezvo PLA, PHA nePTMT zviri izvo zvinonyanya kuvimbisa zvinhu mukuita kwechokwadi kwezvinhu uye TPS firimu mukutsiva petroleum, chiyero chebio based plastic film chicharamba chichiwedzera.
