Mu June 2022, boma la China lidalengeza kuti lidzakhazikitsa "Replace Plastic with Bamboo" ntchito yachitukuko padziko lonse lapansi ndi International Bamboo and Rattan Organization kuti achepetse kuipitsidwa kwa pulasitiki popanga zinthu zatsopano za nsungwi m'malo mwa pulasitiki, ndikulimbikitsa njira zothetsera chilengedwe ndi chilengedwe. nkhani zanyengo.
Ndiye, tanthauzo la "kulowetsa nsungwi m'malo mwa pulasitiki" ndi chiyani?
Choyamba, nsungwi zimangowonjezedwanso, kakulidwe kake ndi kochepa, ndipo zimatha kukhwima pakatha zaka 3-5.Malingana ndi deta, kutulutsa kwa nkhalango ya nsungwi m'dziko langa kudzafika 4.10 biliyoni mu 2021, ndi 4.42 biliyoni mu 2022. Pulasitiki ndi mtundu wa An zinthu zopangira zotengedwa ku mafuta osakanizika, ndipo mafuta amafuta ndi ochepa.
Kachiwiri, nsungwi zimatha kupanga photosynthesis, kutulutsa mpweya pambuyo pokoka mpweya woipa, ndi kuyeretsa mpweya;mapulasitiki alibe phindu kwa chilengedwe.Kuphatikiza apo, njira zazikulu zochizira mapulasitiki a zinyalala padziko lapansi ndi kutayira, kutenthedwa, kung'ung'udza pang'ono kwa granulation ndi pyrolysis, kutayira zinyalala za pulasitiki kuwononga madzi apansi pamlingo wina, ndipo kuwotcha kudzaipitsanso chilengedwe.Mwa matani 9 biliyoni a zinthu zapulasitiki zomwe zimagwiritsidwa ntchito pokonzanso, ndi matani 2 biliyoni okha omwe amagwiritsidwa ntchito.
Kuphatikiza apo, nsungwi zimachokera ku chilengedwe ndipo zimatha kuonongeka mwachangu m'malo achilengedwe osayambitsa kuipitsidwa kwachiwiri.Malingana ndi kafukufuku ndi kusanthula, nthawi yayitali kwambiri yowonongeka kwa nsungwi ndi zaka 2-3 zokha;pomwe zinthu zapulasitiki zimatayidwa.Kuwonongeka kumatenga zaka makumi angapo mpaka mazana.
Pofika chaka cha 2022, mayiko opitilira 140 adapanga momveka bwino kapena apereka malamulo oletsa pulasitiki ndi malamulo oletsa pulasitiki.Kuonjezera apo, misonkhano yambiri ya mayiko ndi mabungwe a mayiko akugwiranso ntchito kuti athandize mayiko kuti achepetse ndi kuthetsa zinthu zapulasitiki, kulimbikitsa kupanga njira zina, ndi kusintha ndondomeko za mafakitale ndi zamalonda kuti achepetse kuwonongeka kwa pulasitiki.
Mwachidule, "kulowetsa pulasitiki ndi nsungwi" kumapereka njira yothetsera chitukuko chokhazikika pazochitika zapadziko lonse monga kusintha kwa nyengo, kuwonongeka kwa pulasitiki, ndi chitukuko chobiriwira, komanso kumathandizira kwambiri chitukuko chokhazikika cha dziko lapansi.perekani.
