Nekuenderera mberi kwekuvandudzwa kwekuziva kwezvakatipoteredza, indasitiri yezvizorwa yakaunzawo shanduko yakasvibira mukurongedza. Traditional petroleum-based plastic packaging haingopedzi zviwanikwa zvakawanda panguva yekugadzira, asi zvakare inokonzeresa kusvibiswa kwezvakatipoteredza panguva yekurapa mushure mekushandisa. Naizvozvo, kuongorora zvakagadzika zvekurongedza zvinhu zvave nyaya yakakosha muindasitiri yezvizoro.
Petroleum-based plastics
Petroleum-based plastics imhando yemidziyo yepurasitiki yakagadzirwa nemafuta emafuta akadai sepetroleum. Iine plastiki yakanaka uye mechanical properties, saka inoshandiswa zvakanyanya munzvimbo dzakasiyana-siyana. Kunyanya, petroleum-based mapurasitiki anosanganisira anotevera akajairika marudzi:
Polyethylene (PE)
Polypropylene (PP)
Polyvinyl chloride (PVC)
Polystyrene (PS)
Polycarbonate (PC)
Petroleum-yakavakirwa mapurasitiki anotonga zvekushongedza kurongedza nekuda kwehuremu hwavo, kusimba uye mutengo-kushanda. Petroleum-based mapurasitiki ane simba rakakwirira uye kuoma, zvirinani makemikari kuramba uye zvirinani processability kupfuura echinyakare mapurasitiki. Zvisinei, kugadzirwa kwechinhu ichi kunoda zviwanikwa zvakawanda zvepetroleum, zvichiwedzera kuderera kwezviwanikwa zvepasi. Iyo CO2 emissions inogadzirwa panguva yekugadzira kwayo yakakwira uye ine imwe mhedzisiro pane zvakatipoteredza. Panguva imwecheteyo, kuputirwa kwepurasitiki kunowanzoraswa zvisizvo mushure mekushandiswa uye zvakaoma kusvibisa mushure mekupinda munzvimbo yakasikwa, zvichikonzera kukuvadza kwakakomba kune ivhu, zvitubu zvemvura uye mhuka dzesango.
Innovative dhizaini mhinduro kune inogoneka kurongedza
Purasitiki yakadzokororwa
Purasitiki yakadzokororwa rudzi rutsva rwezvinhu zvakagadzirwa kubva mumarara epurasitiki kuburikidza nemaitiro akadai sekupwanya, kuchenesa, uye kunyungudutsa. Iine zvimiro zvakafanana kune virgin plastic, asi inoshandisa zviwanikwa zvishoma mukugadzirwa kwayo. Kushandisa mapurasitiki akadzokororwa sezvizoro zvekurongedza zvinhu hazvingodzikisi kuvimba nezviwanikwa zvepetroleum, asi zvakare kuderedza kuburitsa kabhoni panguva yekugadzira.
Bioplastics
Bioplastic ipurasitiki zvinhu zvakagadziriswa kubva kubiomass zviwanikwa (senge starch, cellulose, nezvimwewo) kuburikidza nekuvirisa kwebiological, synthesis uye mamwe maitiro. Iine zvinhu zvakafanana nemapurasitiki echinyakare, asi inogona kushatisa nekukurumidza munzvimbo yechisikigo uye inoshamwaridzana nenharaunda. Izvo zvigadzirwa zvebioplastics zvinobva kwakasiyana siyana, kusanganisira mashanga ezvirimwa, tsvina yehuni, nezvimwewo, uye zvinogoneka kuvandudzwa.
Alternative packaging materials
Pamusoro pemapurasitiki akadzokororwa uye bioplastics, kune zvimwe zvakawanda zvakatsiga zvekutakura zvinhu zviripo. Semuyenzaniso, mapepa ekurongedza zvinhu zvine zvazvakanakira zvekureruka, zvidzokororwe uye zvinoshatisa, uye zvakakodzerwa kushandiswa mukati mekurongedza kwezvizoro. Kunyangwe magirazi ekurongedza zvinhu zvichirema, zvine kusimba kwakanyanya uye kudzoreredza uye anogona kushandiswa kurongedza yakakwirira-yekupedzisira zvizoro. Pamusoro pezvo, kune zvimwe zvitsva zvebio-based composite zvinhu, simbi inoumba zvinhu, nezvimwewo, izvo zvinopawo mamwe sarudzo dzekushongedza kwekurongedza.
Brands uye vatengi pamwe chete kuwana budiriro inoenderera
Kuwana kusimudzira kwakasimba kwezvizoro kurongedza kunoda kuedza kwakabatana kwema brand nevatengi. Panyaya yemabhureki, zvigadziriso zvekurongedza uye matekinoroji zvinofanirwa kuongororwa uye kushandiswa kudzikisa kukanganisa kwakashata kwekurongedza pane zvakatipoteredza. Panguva imwecheteyo, mabhureki anofanirwawo kusimbisa dzidzo yezvakatipoteredza kune vatengi uye kutungamira vatengi kuti vamise pfungwa dzekushandisa dzakasvibirira. Vatengi vanofanirwa kutarisisa kurongedza zvinhu zvezvigadzirwa uye kupa pamberi kune zvigadzirwa zvine kurongedza kwakasimba. Panguva yekushandiswa, huwandu hwekuputira hunoshandiswa hunofanirwa kudzikiswa zvakanyanya sezvinobvira, uye marara ekurongedza anofanirwa kurongeka nenzira kwayo uye kuraswa.
Muchidimbu, shanduko yakasvibira yezvizoro zvekurongedza inzira yakakosha yekuti indasitiri yezvizorwa iwane budiriro inoenderera. Nekutora zvakagadzika zvekutakura zvinhu uye matekinoroji uye kusimbisa dzidzo yezvakatipoteredza, mabhureki nevatengi vanogona kubatsira pamwe kune ramangwana repasi.
