Zvinoenderana nenhamba kubva kuDhipatimendi Rekuchengetedza Kwemamiriro ekunze reHong Kong SAR Government muna 2022, matani mazana maviri nemakumi maviri nenomwe epurasitiki uye styrofoam tableware anoraswa muHong Kong mazuva ese, inova huwandu hukuru hwematani anopfuura zviuru makumi masere nemaviri gore rega rega. Kuti tigadzirise dambudziko rezvakatipoteredza rinokonzerwa nezvigadzirwa zvepurasitiki zvinoraswa, hurumende yeSAR yakazivisa kuti mitemo ine chekuita nekudzora kwekuraswa epurasitiki tableware uye zvimwe zvigadzirwa zvepurasitiki ichaitwa kubva Kubvumbi 22, 2024, zvichiratidza kutanga kwechitsauko chitsva muHong. Zviito zvekuchengetedza zvakatipoteredza zveKong. Nekudaro, nzira yekuenda kune dzimwe nzira dzakasimba haisi nyore, uye zvinhu zvinoodza biodegradable, nepo zvichivimbisa, zvinosangana nematambudziko akaomarara. Muchirevo chechinyorwa chino, tinofanira kuongorora zvine hungwaru nzira dzese, kudzivirira “girinhi musungo”, uye kusimudzira mhinduro dzinoenderana nenharaunda.
Musi waApril 22, 2024, Hong Kong yakatanga nhanho yekutanga yekumisikidzwa kwemitemo ine chekuita nekutonga kwekuraswa epurasitiki tableware nezvimwe zvigadzirwa zvepurasitiki. Izvi zvinoreva kuti hazvibvumidzwe kutengesa nekupa mhando 9 dzetafura yepurasitiki inoraswa idiki muhukuru uye yakaoma kudzokorodza (inovhara yakawedzera polystyrene tableware, mashanga, stirrers, makapu epurasitiki uye midziyo yechikafu, nezvimwewo), pamwe nedonje swabs. , zvivharo zveamburera, mahotera, nezvimwewo. Zvigadzirwa zvakajairika sezvimbuzi zvinoraswa. Chinangwa chekufambisa kwakanaka uku ndechekugadzirisa kukuvadzwa kwezvakatipoteredza kunokonzerwa ne-single-kushandisa zvigadzirwa zvepurasitiki, uku uchishingairira kukurudzira vanhu nemabhizinesi kuti vachinje kune dzimwe nzira dzine hushamwari uye dzakasimba.
Zviratidziro zviri pamhenderekedzo yegungwa yeHong Kong zvinoridza nyevero yekuchengetedzwa kwezvakatipoteredza. Tinoda chaizvoizvo kugara mumhoteredzo yakadaro here? Nei pasi riripo? Nekudaro, chiri kunyanya kunetsa ndechekuti Hong Kong's plastiki recycling rate yakaderera zvakanyanya! Zvinoenderana nedata ra2021, chete 5.7% yemapurasitiki akadzokororwa muHong Kong akagadziriswazve. Iyi nhamba inokatyamadza inokurumidza inoda kuti titore matanho nekukurumidza kutarisana nedambudziko remarara epurasitiki uye nekushingairira kusimudzira shanduko yemagariro kune kushandiswa kwezvimwe zvakatipoteredza uye zvinogara zvichigadziriswa.
Saka ndedzipi dzimwe nzira dzakasimba?
Kunyange zvazvo maindasitiri akasiyana-siyana ari kushingaira kuongorora zvinhu zvinoparara zvakadai sepolylactic acid (PLA) kana bagasse (fibrous material yakatorwa kubva padzinde renzimbe) semwaranzi wetariro yekugadzirisa dambudziko rekusvibiswa kwepurasitiki, dambudziko nderekuti. chaizvoizvo vane ushamwari hwezvakatipoteredza. Ichokwadi kuti biodegradable zvinhu zvichaputsika uye kushatisa nokukurumidza, nokudaro kuderedza ngozi yekusingaperi kusvibiswa kwezvakatipoteredza kubva mumarara epurasitiki. Nekudaro, chatisingafanire kufuratira ndechekuti huwandu hwemagasi egreenhouse anoburitswa panguva yekushatiswa kwezvinhu izvi (senge polylactic acid kana bepa) muHong Kong's landfills akakwira zvakanyanya kupfuura emapurasitiki echinyakare.
Muna 2020, iyo Life Cycle Initiative yakapedzisa meta-kuongorora. Ongororo iyi inopa pfupiso yehutsananguro yehupenyu hwekutenderera ongororo mishumo pazvinhu zvakasiyana-siyana zvekurongedza, uye mhedziso inoodza moyo: bio-based mapurasitiki (biodegradable mapurasitiki) akagadzirwa kubva kune zvakasikwa zvinhu zvakaita secassava nechibage zvine huipi hunokanganisa nharaunda Kuita mukukanganisa. dimension haisi nani pane fossil-based plastics sezvataitarisira
Masikati mabhokisi akagadzirwa ne polystyrene, polylactic asidhi (chibage), polylactic asidhi (tapioca starch)
Bio-based mapurasitiki haakodzeri nani pane fossil-based mapurasitiki. Sei izvi?
Chimwe chikonzero chakakosha ndechekuti chikamu chekugadzira zvekurima chinodhura: kugadzira bio-based plastics (biodegradable plastics) kunoda nzvimbo dzakakura dzevhu, yakawanda yemvura, uye makemikari ekushandisa senge mishonga yezvipembenene nefetereza, izvo zvisingadzivisiki Emissions kuvhu, mvura nemhepo. .
Nhanho yekugadzira uye uremu hwechigadzirwa pachayo zvakare zvinhu zvisingagoni kuregererwa. Tora mabhokisi emasikati akagadzirwa nebagasse semuenzaniso. Sezvo bagasse pachayo isingabatsiri kubva-chigadzirwa, kukanganisa kwayo kune zvakatipoteredza panguva yekurima kwekurima kudiki. Nekudaro, iyo inotevera bleaching process yebagasse pulp uye kuyerera kwemvura yetsvina kwakagadzirwa mushure mekugeza pulp kwakave nemhedzisiro yakaipa munzvimbo dzakawanda dzakadai semamiriro ekunze, hutano hwevanhu uye huturu hwezvakatipoteredza. Kune rumwe rutivi, kunyange zvazvo kubudiswa kwezvinhu zvakasvibiswa uye kugadzirwa kwepolystyrene foam boxes (PS foam boxes) zvinosanganisirawo nhamba yakawanda yemakemikari uye maitiro emuviri, sezvo bagasse ine uremu hukuru, inowanzoda zvimwe zvinhu, izvo zvakaoma zvikuru. Izvi zvinogona kutungamirira kuhuwandu hwehuwandu hwehuwandu hwehuwandu hwehuwandu hwehupenyu hwose. Nokudaro, tinofanira kuziva kuti kunyange zvazvo nzira dzekugadzira uye kuongororwa kwezvigadzirwa zvakasiyana-siyana zvakasiyana-siyana, zvakaoma kugumisa zviri nyore kuti ndeipi "sarudzo yakanakisisa" yeimwe nzira yekushandisa imwe chete.
Saka izvi zvinoreva here kuti tinofanira kudzokera kupurasitiki?
Mhinduro ndeyekuti kwete. Zvichienderana nezviwanikwa zvazvino, zvinofanirwa kuve pachena kuti dzimwe nzira dzepurasitiki dzinogona kuuya zvakare nekukanganisa nharaunda. Kana idzi sarudzo dzekushandisa kamwe chete dzikasapa mhinduro dzakasimba dzatinotarisira, saka tinofanira kuongorora zvakare kukosha kwezvigadzirwa zvekushandisa kamwe chete uye kuongorora zvingangogona kuita kuderedza kana kudzivirira kushandiswa kwazvo. Matanho ehurumende yeSAR akawanda ekuita, akadai sekumisikidza nguva dzekugadzirira, kusimudzira dzidzo yeveruzhinji uye kushambadza, uye kumisa chikuva cheruzivo chekugovana dzimwe nzira dzekushandisa chete zvigadzirwa zvepurasitiki, zvese zvinoratidza chinhu chakakosha chisingagoni kufuratirwa chinokanganisa "purasitiki" yeHong Kong. -yemahara” maitiro, ari kuti vagari vekuHong Kong varikuda Gamuchira dzimwe nzira idzi, sekupa kuunza bhodhoro rako remvura nemidziyo. Kuchinja kwakadaro kwakakosha mukusimudzira mararamiro ane hushamwari.
Kune avo vagari vanokanganwa (kana vasingade) kuunza midziyo yavo, kuongorora nzira yekukwereta nekudzorera yemidziyo inogona kushandiswa zvakare yave mhinduro uye inogoneka. Kuburikidza nehurongwa uhu, vatengi vanogona kukwereta zviri nyore midziyo inogona kushandiswa zvakare voidzosera kunzvimbo dzakatarwa mushure mekushandisa. Zvichienzaniswa nezvinhu zvinoraswa, kuwedzera chiyero chekushandisazve midziyo iyi, kutora nzira dzekuchenesa dzakasimba, uye kuenderera mberi nekugadzirisa dhizaini yekukwereta nekudzorera system inogona kushanda pachiyero chepakati chekudzoka (80%, ~5 cycles) Kuderedza kuburitsa gasi regreenhouse ( 12-22%), kushandiswa kwezvinhu (34-48%), uye zvakakwana kuchengetedza kushandiswa kwemvura ne16% kusvika 40%. Nenzira iyi, BYO kapu uye inogona kushandiswazve chikwereti chemidziyo uye masisitimu ekudzoka anogona kuve sarudzo yakatsiga mukutora uye kuburitsa mamiriro.
Kurambidzwa kweHong Kong kwekushandisa kamwe chete zvigadzirwa zvepurasitiki pasina mubvunzo idanho rakakosha mukugadzirisa dambudziko rekusvibiswa kwepurasitiki uye kushatiswa kwezvakatipoteredza. Kunyange zvazvo zvisingaiti kubvisa zvachose zvigadzirwa zvepurasitiki muupenyu hwedu, tinofanira kuziva kuti kungokurudzira dzimwe nzira dzinoraswa haisi mhinduro inokosha uye zvinogona kukonzera matambudziko matsva ezvakatipoteredza; pane zvakasiyana, tinofanira kubatsira pasi kubvisa husungwa hwe "plastiki" Chinokosha ndechekusimudzira ruzivo rwevanhu: rega munhu wose anzwisise kupi kudzivisa zvachose kushandiswa kwepurasitiki uye kurongedza, uye nguva yekusarudza zvigadzirwa zvekushandisa zvakare, apo uchiedza kuderedza kushandiswa kwezvigadzirwa zvekushandisa kamwe chete kusimudzira girinhi, mararamiro akasimba.
