Kusvibiswa kwepurasitiki kutyisidzira kukuru kune zvakatipoteredza uye yava nyaya yekunetsa pasi rose. Mabhegi epurasitiki echinyakare ndiwo anonyanya kukonzera dambudziko iri, nemamiriyoni emabhegi anoguma azara mumarara nemakungwa gore rega rega. Mumakore achangopfuura, compostable uye biodegradable mabhegi epurasitiki akabuda semhinduro inogona kunetsa iyi.
Mabhegi epurasitiki anogadzirwa anogadzirwa kubva kumiti-yakavakirwa zvinhu, senge cornstarch, uye akagadzirirwa kuputsika nekukurumidza uye zvakachengeteka mucompost masisitimu. Mabhegi epurasitiki anogadzika, kune rumwe rutivi, anogadzirwa kubva kuzvinhu zvinogona kuputswa netupukanana mumhoteredzo, semafuta emiriwo uye starch yembatatisi. Mhando mbiri dzemabhegi dzinopa imwe yakasarudzika nharaunda kune echinyakare mabhegi epurasitiki.
Mishumo yenhau ichangoburwa yakaratidza dambudziko riri kukura rekusvibiswa kwepurasitiki uye kudiwa kwekukurumidzira kwemhinduro dzakasimba. Muchidzidzo chakaburitswa mupepanhau reScience, vaongorori vakafungidzira kuti pari zvino pane zvidimbu zvepurasitiki zvinodarika 5 miriyoni mumakungwa epasirese, uye inofungidzirwa kuti mamiriyoni masere ematani epurasitiki anopinda mugungwa gore rega rega.
Kurwisa nyaya iyi, nyika zhinji dzakatanga kumisa kurambidza kana mitero pamabhegi epurasitiki echinyakare. Muna 2019, New York yakava nyika yechitatu yeUS kurambidza mabhegi epurasitiki anoshandiswa chete, achibatana neCalifornia neHawaii. Saizvozvo, European Union yakazivisa hurongwa hwekurambidza-kushandisa chete zvigadzirwa zvepurasitiki, kusanganisira mabhegi epurasitiki, panosvika 2021.
Mabhegi epurasitiki anonyoroveswa uye anoodeka anopa mhinduro kudambudziko iri, sezvo akagadzirirwa kuputsika nekukurumidza kupfuura masaga epurasitiki echinyakare uye haana kukuvadza kune zvakatipoteredza. Zvinoderedzawo kuvimba kwedu nemafuta asingadzokerikezve anoshandiswa kugadzira mabhegi epurasitiki echinyakare. Zvichakadaro, tinofanira kuziva kuti mabhegi aya achiri kuda kuraswa kwakakodzera kuitira kuti zvinyatso kudzikisa kusvibiswa kwepurasitiki. Kungoakanda mumarara kunogona kukonzera dambudziko racho.
Mukupedzisa, compostable uye biodegradable epurasitiki mabhegi anopa imwe yakagadzikana imwe kune echinyakare masaga epurasitiki uye ane mukana wekubatsira kurwisa kusvibiswa kwepurasitiki. Sezvo isu tichiramba tichigadzirisa nyaya yekusvibiswa kwepurasitiki, zvakakosha kuti titsvage uye tigamuchire mhinduro dzakasimba.
