The zaka makumi ochepa anthu yatulusa zinyalala banja mwaunyinji. Mu mzinda wamakono m'chaka anapeza pafupifupi 300 makilogalamu zinyalala pa munthu, kotero processing zinyalala - mmodzi wa m'magazini kukanikiza wa lero.
Kuchotsa ndi kutaya zinyalala ndi ntchito zenizeni kwambiri, amafuna kugwiritsa ntchito luso lapadera. processing n'kofunika osati kuwayang'anira kukhazikitsa malamulo ambiri ndi malamulo, komanso kugwiritsa ntchito njira ndi zipangizo. Nthawi zambiri, zinyalala mafakitale lili zoipa zinthu anthu - zitsulo, dioxins, fluoride. Onse a iwo ndi owopsa kwambiri thanzi la munthu. zinthu zovulaza ndi madzi a mvula mu nthaka, mpweya lalikulu zedi anamasulidwa woipa sulfure ndi dziko. Zinyalala mu landfills pakubwera ngozi kuyaka lachibadwa. Komanso, lotayako oletsedwa ndi kuswana pansi tizilombo ndi makoswe.
njira zamakono vuto - kutaya zinyalala banja ndi kuthekera ntchito zawo zina. Kuthera nthawi, mphamvu ndi ndalama kuwononga chiwonongeko wolowerera. Komabe, zamakono amalola osati kwa bwinobwino akonzanso zinyalala, komanso kupeza madalitso a. Kutaya zinyalala amafuna inayake processing, zotsatira zake zidzakhala itengedwe ndi kuthekera zingagwiritsidwenso ntchito zawo.
Zinyalala pepala, zitsulo zotha ntchito, ndi galasi akhoza mwachindunji ntchito. zinyalala zomangamanga, amene sasintha katundu wawo, angathe kuikidwa m'manda mu nthaka. zinyansi olimba kwenikweni ntchito mafuta. Analandira pambuyo zinyalala mafuta khalidwe lofanana bulauni khala ndi peat. Asayansi amakhulupirira kuti mphamvu akamagwira kutembenuka zinyalala mu mphamvu ndi mafuta, adzatha kuphimba gawo limodzi mwa zosowa za chuma cha dziko. mtundu wina wa magwiritsidwe zinyalala olimba - ndi umapezeka ndi kutembenuka mtima kwawo kwa zomangira. Mwachitsanzo, wosweka ndi ting'onoting'ono basi pulasitiki ali osokonezeka ndi phula ndi mafuta resins ndi ntchito yomanga msewu. Komanso ong'ambika pulasitiki ntchito kubala mafilimu, zipangizo denga ndi zidole.
Kutaya zinyalala kuti ayenera kukumana processing wapakatikati - ndi soda, asidi, mafuta ntchito. Part slop zinthu dewatered ndi zouma. Gawo la mankhwala kuyaka, monga mafuta zinyalala ndi mapulasitiki - kutenthedwa. Mu zinyalala mankhwala amakono zomera akhazikitsidwa yobwezeretsanso wa banja ndi zinyalala mafakitale, umisiri wapadera amakulolani mtundu, udzaphwanya ndi kuzindikira zinyalala nusu, owopsa kwa chilengedwe ndi thanzi la munthu. The padziko lonse lonse kusalankhula kudzikundikira banja ndi mafakitale zinyansi zimabweretsa kusintha kuopseza mpweya bwino ndi mpweya mu chikhalidwe, kuchepetsa kuchuluka kwa madzi akumwa. Iwo zikuphatikizapo kuipitsa nthaka ndi kuwononga matupi madzi, kusintha kwa nyengo. Ntchito yaikulu kwambiri ya chuma cha padziko lonse kwagona kuti yobwezeretsanso zinyalala banja wadutsa angapo zoopsa zingapo umisiri.
