Nyanzvi mugadziri wemichina ye thermoforming.
Midziyo inoraswa, inonyanya kugadzirwa kubva mupurasitiki nemapepa, inokonzeresa matambudziko ezvakatipoteredza. Midziyo yepurasitiki, inowanikwa kwose kwose mukushandiswa kwayo, inobatsira kumatambudziko epasi rose ekusvibiswa kwepurasitiki. Hunhu hwavo husina-biodegradable hunoreva kuti vanoramba vari mumhoteredzo kwemazana emakore, vachisvibisa nzira dzemvura, kuisa mhuka dzesango munjodzi, uye kutyisidzira hutano hwevanhu kuburikidza nekupinzwa kwema microplastics.
Nepo midziyo yemapepa ichigoneka, kugadzirwa kwayo kunosanganisira kushandiswa kwakanyanya kwezviwanikwa, kusanganisira mvura, simba, uye pulp yehuni. Kutemwa kwemasango, tsika yakajairika mukugadzirwa kwemapepa, kunotungamirira kukurasikirwa kwenzvimbo yekugara, kuparara kwezvipenyu zvakasiyana-siyana, uye kuwedzera kubudiswa kwekabhoni, zvichiwedzera kuchinja kwemamiriro ekunze.
Pakati pekunetseka kuri kukura pamusoro pekukanganisa kwezvakatipoteredza kwemidziyo yechinyakare inoraswa, zvimwe zvinhu zvakabuda semhinduro dzinogona kuitika:
a. Bamboo:
Midziyo ye bamboo inopa imwe yakagadzikana imwe kune epurasitiki nemapepa. Bamboo chinhu chiri kukurumidza kuvandudzwa chinoda mvura shoma uye pasina mishonga yekuuraya zvipembenene kana fetereza yekurimwa. Pamusoro pezvo, midziyo yemushenjere inogara yakasimba, inoora, uye isina huremu, zvichiita kuti ive yakakodzera kushandiswa-kamwe chete.
b. Nhumbe Bagasse:
Nhumbe, iyo nzimbe inogadzirwa nenzimbe, inogona kuumbwa kuva midziyo, ndiro, uye midziyo. Kushandisa bagasse sechinhu chisina kubikwa kunoderedza marara kubva mukugadzirwa kwenzimbe uye kunopa imwe biodegradable imwe nzira kune yechinyakare midziyo inoraswa.
c. PLA (Polylactic Acid):
Polylactic Acid (PLA) inotorwa kubva kune yakaviriswa chirimwa starch (kazhinji chibage) uye inomiririra inogona kuvandudzwa, biodegradable imwe nzira kune petroleum-based mapurasitiki. Kugadzirwa kwePLA kunoburitsa magasi egreenhouse mashoma uye kunoda simba shoma kana zvichienzaniswa nemapurasitiki echinyakare. Zvisinei, haisiriyo chete kwakabva PLA inoita kuti inakidze asiwo sarudzo dzayo dzekuguma kwehupenyu; PLA inogona kugadzirwa muindasitiri, ichiputsika kuita zvinhu zvakasikwa pasi pemamiriro akakodzera, mukana wakakura pane akajairwa mapurasitiki.
Kugadzirwa kwemidziyo yePLA kunosanganisira hunyanzvi hwekuvandudza tekinoroji, kunyanyaPLA thermoforming michina uyePLA epurasitiki mukombe kugadzira michina. Thermoforming inzira iyo mapepa ePLA anopisa uye obva aumbwa kuva maumbirwo chaiwo-akadai semahwendefa, cutlery, kana makapu-uchishandisa molds. Iyi tekinoroji haingotsigire chete kusikwa kwezvakaomarara uye zvakasiyana-siyana zvigadzirwa zvekugadzira asi inozviita nekushanda kwakanyanya uye kushomeka kwesimba rekushandisa. Aya maitiro anoita kuti midziyo yePLA iite zvese zvakatipoteredza uye zvehupfumi.
Paunenge uchiongorora zvinhu zvakaita sepolystyrene, polyethylene, uye compostable bepa, PLA inowanzomira pachena nekuda kwekushomeka kwayo kwezvakatipoteredza. Kusiyana nepolystyrene uye polyethylene, PLA haibvi kubva kune inogumira zvisaririra zvezviwanikwa uye inozvikudza zviri nani biodegradability kupfuura aya mapurasitiki. Kunyangwe bepa recompostable richikwikwidza zvakasimba, kugadzirwa kwezvigadzirwa zvemapepa kunowanzobatanidza kushandiswa kwemvura yakakwirira uye simba, uye zvigadzirwa zvekupedzisira hazvina kusimba kana kuita zvakasiyana-siyana sezvakaitwa kubva kuPLA.
Mabhizinesi mazhinji ari kuchinjika kuenda kuPLA midziyo yekusimudzira maprofiles avo. Kune vatengi, kusarudzira PLA-yakavakirwa midziyo inoraswa inogona kuve nhanho inoshanda yekudzikisa kukanganiswa kwezvakatipoteredza. Kuziva uye kudiwa kubva kuvatengi kunogona kukanganisa zvakanyanya zvinopihwa pamusika, zvichikurudzira makambani mazhinji kuti atarise maitiro akasimba mukushanda kwawo. Pakupedzisira, maitiro evatengi anoita basa rakakosha mukusimudzira kuchengetedza kwezvakatipoteredza:
a. Dzidzo uye Kuziva:
Kusimudza ruzivo pamusoro pekukanganisa kwezvakatipoteredza kwemidziyo inoraswa uye zvakanakira kusarudza zvinogoneka. Kudzidzisa vatengi nezve nzira dzakakodzera dzekurasa uye kukosha kwekudzikisa-yekushandisa mapurasitiki anogona kutyaira shanduko yehunhu.
b. Kuchinja maitiro:
Kukurudzira vatengi kuti vasarudze midziyo inogona kushandiswazve pese pazvinogoneka uye kusarudza zvinoraswa zvine hushamwari kana zvichidikanwa. Nekuita sarudzo dzekuziva panguva yekutenga, vatengi vanogona kudzikisa tsoka yavo yezvakatipoteredza uye kubatsira kune shanduko yakanaka.
c. Policy uye Regulation:
Kuita marongero anokurudzira kushandiswa kwezvinhu zvakagadzikana uye kusimudzira kuvandudzwa kwezvivakwa zvekurasa kwakaringana nekudzokorodza. Mitemo yehurumende, zviyero zveindasitiri, uye zvirongwa zvemakambani zvinogona kufambisa hunyanzvi uye kuzvidavirira mukugadzira uye kushandiswa kwemidziyo inoraswa.
Kusarudza chinhu chakakodzera chemidziyo inoraswa isarudzo ine mativi mazhinji inoda kutariswa kwemamiriro ekunze, kushandiswa kwezviwanikwa, uye kufambira mberi kwetekinoroji. PLA inobuda sesarudzo inotungamira nekuda kweiyo bviro inogona kuvandudzwa, biodegradability, uye yakaderera kabhoni tsoka. Sezvo tekinoroji ichifambira mberi uye kuziva kwevatengi kuchikura, kutorwa kwemidziyo yePLA kunogona kuita basa rakakosha mukudzikamisa nyaya dzezvakatipoteredza dzine chekuita nemapurasitiki anoraswa. Kufambira mberi, zvakakosha kuti hutsva hurambe huchikwenenzvera nekuwedzera mashandisirwo ePLA, kuve nechokwadi chekuti kugadzikana hakukanganisi kushanda kana kuwanikwa.
