Regenerating "green" kubva mumabhodhoro epurasitiki
PET (PolyEthylene Terephthalate) imwe yemapurasitiki anoshandiswa zvakanyanya. Iine yakanaka ductility, yakakwirira pachena, uye kuchengeteka kwakanaka. Inowanzo shandiswa kugadzira mabhodhoro ezvinwiwa kana zvimwe zvinhu zvekurongedza chikafu. . Munyika yangu, rPET (yakadzokororwa PET, yakadzokororwa PET plastiki) yakagadzirwa kubva kumabhodhoro echinwiwa akadzokororwa anogona kushandiswa zvakare mumotokari, makemikari ezuva nezuva nemimwe minda, asi parizvino haibvumidzwe kushandiswa mukurongedza chikafu. Muna 2019, huremu hwechinwiwa PET mabhodhoro akadyiwa munyika yangu akasvika 4.42 miriyoni matani. Nekudaro, PET inotora angangoita mazana emakore kuti iparare zvachose pasi pemamiriro echisikigo, izvo zvinounza mutoro mukuru kune zvakatipoteredza uye hupfumi.
Kubva pakuona kwehupfumi, kurasa mapurasitiki epurasitiki mushure mekushandisa imwe nguva icharasikirwa ne95% yekushandiswa kwayo; kubva pamaonero ezvakatipoteredza, zvinozotungamira mukuderedza goho rezvirimwa, kusvibiswa kwegungwa uye mamwe matambudziko mazhinji. Kana akashandiswa PET mabhodhoro epurasitiki, kunyanya mabhodhoro ezvinwiwa, akadzokororwa kuti adzokororwe, zvichave zvakakosha mukuchengetedza kwezvakatipoteredza, hupfumi, nzanga uye zvimwe zvinhu.
Dhata inoratidza kuti mwero wekudzokorodza wemabhodhoro echinwiwa chePET munyika mangu unosvika 94%, ayo anopfuura makumi masere muzana erPET anopinda muindasitiri yefiber yakadzokororwa uye inoshandiswa kugadzira zvinodikanwa zvezuva nezuva semabhegi, zvipfeko, uye parasols. Muchokwadi, kugadzirisa mabhodhoro echinwiwa ePET kuita giredhi-giredhi rPET hakungogone kuderedza kushandiswa kwemhandara PET uye kuderedza kushandiswa kwezvinhu zvisingadzokerikezve sepetroleum, asi zvakare kuwedzera huwandu hwekutenderera kwerPET kuburikidza nesainzi uye yakasimba kugadzirisa maitiro, kuita kuchengeteka kwayo Yakatove yakaratidza kune dzimwe nyika.
Pamusoro pekupinda muhurongwa hwekudzokorodza, mabhodhoro ezvinwiwa zvePET emunyika yangu anonyanya kuyerera achienda kumafekitari emarara echikafu, marara, zvidyarwa zvemagetsi ekupisa marara, mabhichi nedzimwe nzvimbo. Nekudaro, kuzara kwevhu uye kupisa kunogona kukonzera kusvibiswa kwemhepo, ivhu uye pasi pevhu. Kana tsvina ikaderedzwa kana marara akawanda akashandiswazve, mitoro yezvakatipoteredza uye mari inogona kuderedzwa.
Yakagadzirwazve PET inogona kuderedza carbon dioxide emissions ne59% uye kushandiswa kwesimba ne76% zvichienzaniswa nePET yakagadzirwa nepetroleum.
Muna 2020, nyika yangu yakaita kuzvipira kwepamusoro pakuchengetedza kwezvakatipoteredza uye kuderedza kusvibiswa kwemhepo: kuzadzisa chinangwa chepamusoro-soro kabhoni pamberi pe2030 uye kuve nekabhoni isina kwayakarerekera pamberi pe2060. kushandurwa kwehupfumi nehupfumi hwevanhu. Seimwe yenzira dzinoshanda dzekudzorerazve mapurasitiki emarara, rPET inogona kuita basa mukusimudzira kuongororwa nekuvandudzwa kwemararamiro emararamiro, uye inokosha zvikuru mukusimudzira kubudirira kwe "double carbon" chinangwa.
Kuchengeteka kwerPET kurongedza chikafu kwakakosha
Parizvino, nekuda kwehushamwari hwezvakatipoteredza zvivakwa zverPET, nyika zhinji nematunhu pasirese zvakabvumira kushandiswa kwayo mukurongedza chikafu, uye Africa iri kuwedzerawo kuwedzera kwayo kugadzirwa. Nekudaro, munyika yangu, rPET plastiki haigone kushandiswa mukurongedza chikafu.
Iko hakuna kushomeka kwechikafu-giredhi rPET mafekitori munyika yedu. Muchokwadi, nyika yedu ndiyo hombe pasi rose kudzokorodza uye kugadzirisa epurasitiki nzvimbo. Muna 2021, nyika yangu yePET chinwiwa bhodhoro rekudzokorodza vhoriyamu ichave pedyo nemamiriyoni mana ematani. rPET plastiki inoshandiswa zvakanyanya muzvizoro zvepamusoro-soro, kurongedza chigadzirwa chemunhu, mota nemimwe minda, uye chikafu-giredhi rPET Inotengeswa kunze kwenyika.
Iyo "Chirevo" inoratidza kuti 73.39% yevatengi vanotora danho rekudzokorodza kana kushandisa zvakare mabhodhoro ezvinwiwa zvakaraswa muhupenyu hwavo hwezuva nezuva, uye 62.84% yevatengi vanotaura zvinangwa zvakanaka zvePET kudzokorora kushandiswa mukudya. Vanopfuura 90% yevatengi vakaratidza kushushikana nezve kuchengetedzeka kwerPET inoshandiswa mumidziyo yekurongedza chikafu. Zvinogona kuonekwa kuti vatengi veChinese vanowanzove nemafungiro akanaka ekushandiswa kwe rPET mukurongedza chikafu, uye kuve nechokwadi chekuchengetedza chinhu chinodiwa.
Iko kushandiswa kwechokwadi kwe rPET mumunda wekudya kunofanirwa kuve kwakavakirwa pakuchengetedza ongororo uye pre- uye mushure mechiitiko chekutarisa kune rumwe rutivi. Kune rumwe rutivi, zvinotarisirwa kuti nzanga yose ichashanda pamwe chete kusimudzira kushandiswa kwepamusoro-kukosha kwerPET uye nekusimudzira kusimudzira hupfumi hwedenderedzwa.
