Kodi madzi a m'botolo la chakumwa ndi abwino?
Kutsegula botolo la madzi amchere kapena chakumwa ndi chinthu chofala, koma kumawonjezera botolo lapulasitiki lotayidwa ku chilengedwe.
Chigawo chachikulu cha phukusi la pulasitiki la zakumwa za carbonated, madzi amchere, mafuta odyera ndi zakudya zina ndi polyethylene terephthalate (PET).Pakadali pano, kugwiritsa ntchito mabotolo a PET kumakhala koyambirira pantchito yonyamula zakudya zamapulasitiki.
Monga phukusi lazakudya, ngati PET palokha ndi chinthu choyenera, iyenera kukhala yotetezeka kwambiri kuti ogula azigwiritsa ntchito nthawi zonse ndipo sizingawononge thanzi.
Kafukufuku wa sayansi wasonyeza kuti ngati mabotolo apulasitiki amagwiritsidwa ntchito mobwerezabwereza kumwa madzi otentha (oposa 70 digiri Celsius) kwa nthawi yaitali, kapena amatenthedwa mwachindunji ndi ma microwaves, zomangira za mankhwala m'mabotolo apulasitiki ndi mapulasitiki ena zidzawonongeka, ndi mapulasitiki opangira pulasitiki. ndipo ma antioxidants amatha kusamutsidwa kupita ku chakumwa.Zinthu monga oxidants ndi oligomers.Zinthu zimenezi zikasamuka mochulukirachulukira, zimakhudza thanzi la omwa.Chifukwa chake, ogula ayenera kuzindikira kuti akamagwiritsa ntchito mabotolo a PET, ayesetse kuti asawadzaze ndi madzi otentha ndikuyesera kuti asawaike mu microwave.
Kodi pali ngozi iliyonse yobisika m'kutaya mutamwa?
Mabotolo apulasitiki amatayidwa ndikumwazika m'misewu ya mizinda, malo oyendera alendo, mitsinje ndi nyanja, komanso mbali zonse za misewu yayikulu ndi njanji.Sikuti amangoyambitsa kuipitsidwa ndi maso, komanso amavulaza.
PET ndi inert kwambiri ndi mankhwala komanso zinthu zosawonongeka zomwe zimatha kukhala m'chilengedwe kwa nthawi yayitali.Izi zikutanthauza kuti ngati mabotolo apulasitiki otayidwa sagwiritsidwanso ntchito, apitiliza kuwunjikana m'chilengedwe, kusweka ndi kuwonongeka kwa chilengedwe, zomwe zimapangitsa kuti madzi amtunda, nthaka ndi nyanja ziwonongeke kwambiri.Zinyalala zambiri za pulasitiki zomwe zimalowa m'nthaka zingasokoneze kwambiri zokolola za nthaka.
Zidutswa za pulasitiki zomwe zimadyedwa mwangozi ndi nyama zakuthengo kapena nyama zam'madzi zimatha kuvulaza nyama ndikuyika chitetezo cha chilengedwe.Malinga ndi bungwe la United Nations Environment Programme (UNEP), 99% ya mbalame zikuyembekezeka kudya pulasitiki pofika 2050.
Kuphatikiza apo, mapulasitiki amatha kuwola kukhala tinthu tating'onoting'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'onoting'ono, tomwe titha kulowetsedwa ndi zamoyo ndipo pamapeto pake zimakhudza thanzi la munthu kudzera muzakudya.Bungwe la United Nations Environment Programme linanena kuti zinyalala zambiri za pulasitiki m'nyanja zikuwopseza chitetezo cha zamoyo zam'madzi, ndipo kuyerekezera kosamala kumapangitsa kuti chuma chiwonongeke mpaka 13 biliyoni ya US dollars chaka chilichonse.Kuwonongeka kwa pulasitiki m'madzi kwalembedwa kuti ndi imodzi mwazinthu khumi zofunika kwambiri za chilengedwe zomwe ziyenera kukhudzidwa m'zaka 10 zapitazi.
Kodi ma microplastics alowa m'miyoyo yathu?
Ma Microplastics, mozama kunena za tinthu tating'ono ta pulasitiki, ulusi, zidutswa, ndi zina zambiri m'malo osakwana 5 mm kukula kwake, ndizomwe zimayang'ana kwambiri popewa komanso kuwongolera kuipitsidwa kwa pulasitiki padziko lonse lapansi.The "Action Plan for Plastic Pollution Control in the 14th 5-year Plan" yoperekedwa ndi dziko langa imatchulanso ma microplastics monga gwero latsopano la kuipitsa kwa nkhawa yaikulu.
Gwero la ma microplastics atha kukhala mapulasitiki achilengedwe, kapena amatha kutulutsidwa ndi zinthu zapulasitiki chifukwa cha kuwala, nyengo, kutentha kwambiri, kuthamanga kwa makina, ndi zina zambiri.
Kafukufuku akuwonetsa kuti ngati anthu amadya ma gramu owonjezera a 5 a microplastics pa sabata, ma microplastics ena sangatulutsidwe mu chopondapo, koma adzaunjikana m'ziwalo za thupi kapena magazi.Kuphatikiza apo, ma microplastics amatha kulowa mu nembanemba ya cell ndikulowa m'thupi la munthu, zomwe zitha kusokoneza magwiridwe antchito a cell.Kafukufuku wapeza kuti ma microplastic poyesa nyama awonetsa zovuta monga kutupa, kutseka kwa maselo ndi metabolism.
Mabuku ambiri a m’nyumba ndi akunja amanena kuti zipangizo zogulitsira zakudya, monga matumba a tiyi, mabotolo a ana, makapu a mapepala, mabokosi a chakudya chamasana, ndi zina zotero, zingatulutse mamicroplastic masauzande kapena mamiliyoni mazanamazana a kukula kosiyanasiyana m’zakudya zikamagwiritsidwa ntchito.Komanso, derali ndi losawona bwino ndipo liyenera kuperekedwa chisamaliro chapadera.
Kodi mabotolo apulasitiki obwezerezedwanso angagwiritsidwenso ntchito?
Kodi mabotolo apulasitiki obwezerezedwanso angagwiritsidwenso ntchito?
Mwachidziwitso, kupatula mabotolo apulasitiki oipitsidwa kwambiri, mabotolo onse a zakumwa amatha kubwezeretsedwanso.Komabe, panthawi yomwe mabotolo a chakumwa cha PET amamwa komanso kukonzanso makina, zowononga zina zakunja zimatha kuyambitsidwa, monga mafuta a chakudya, zotsalira za zakumwa, zoyeretsa m'nyumba, ndi mankhwala ophera tizilombo.Zinthu izi zitha kukhalabe mu PET yobwezerezedwanso.
PET yobwezerezedwanso yomwe ili ndi zinthu zomwe zili pamwambapa ikugwiritsidwa ntchito pazakudya, zinthuzi zimatha kusamukira m'zakudya, motero kuwopseza thanzi la ogula.European Union ndi United States zikunena kuti PET yobwezeretsanso iyenera kukwaniritsa zofunikira zachitetezo kuchokera komwe imachokera isanagwiritsidwe ntchito popakira chakudya.
Ndikusintha kwa chidziwitso cha ogula pakubwezeretsanso mabotolo a zakumwa, kukhazikitsidwa kwa njira yoyeretseranso, komanso kuwongolera mosalekeza kwa zobwezeretsanso ndi kuyeretsa zopangira mapulasitiki amtundu wa chakudya, makampani ochulukirachulukira tsopano akutha kukwaniritsa kukonzanso koyenera komanso kukonzanso koyenera kwa ma pulasitiki. mabotolo a zakumwa.Mabotolo a zakumwa omwe amakwaniritsa zofunikira pachitetezo cha chakudya amapangidwa ndikugwiritsiridwa ntchitonso pakuyika chakumwa.
