Ososayensi bahlola indlela yokusebenzisa i-asbestos emfucumfucwini yasezimayini ukuze kugcinwe inani elikhulu le-carbon dioxide emoyeni ukuze lisize ukubhekana nenkinga yesimo sezulu.
I-Asbestos iyiminerali yemvelo eyake yasetshenziswa kabanzi njengokuvikela ukushisa kanye ne-flame retardant ezakhiweni. Lokhu kusetshenziswa kwaziwa kakhulu ngezakhiwo zabo ze-carcinogenic, kodwa kusetshenziswe kumabhuleki emoto athile kanye nosilingi namathayela ophahleni embonini ye-chlorine. Nakuba amazwe angu-67 okwamanje evimbela ukusetshenziswa kwezinto ze-fiber, i-United States ayilona elinye lawo.
Manje, abacwaningi bagxile ezinhlotsheni ezithile ze-asbestos ene-fibrous, okuyimikhiqizo ewudoti evela ezimayini. Ngokuka-Eos, ikhwalithi ephezulu kakhulu eyenza i-asbestos ibe yingozi ekuhogeleni iphinde ikwenze ikuhlomele kahle ukubamba izinhlayiya ze-carbon dioxide ezintanta emoyeni noma ezincibilike emvuleni. Umbiko uchaza ukuthi indawo ephezulu yamafayibha iwenza “asebenze kakhulu futhi kube lula ukuwaguqula” abe amakhabhoni angenabungozi uma ehlanganiswe nesikhutha. Le nqubo yenzeka ngokwemvelo lapho i-asbestos ibhekene namagesi abamba ukushisa.
Ngokusho kwe-MIT Technology Review, lezi zinto ezizinzile zingavala amagesi abamba ukushisa izigidi zeminyaka futhi zibonise ukuthi ziyindlela esebenzayo yokumunca inani elikhulu le-carbon dioxide emkhathini. Ososayensi banethemba lokuqeda ukukhishwa kwekhabhoni “enkulu” evela emisebenzini yezimayini kuqala, bese andisa imizamo yokunciphisa ukukhishwa kwesisi esibamba ukushisa.
UGregory Dipple, umcwaningi oholayo kulo mkhakha, utshele I-MIT Technology Review: “Eshumini leminyaka elizayo, izimayini zokususa ikhabhoni zizosisiza kuphela sakhe ukuzethemba kanye nobuchwepheshe ukuze sinciphise ukungcola. Nezimayini zangempela ziyenziwa.”
Ngokusho komsakazi we-Kottke Ride Home Podcast uJackson Bird (Jackson Bird) ubike ukuthi uma lezi zinto zingena olwandle ngokugeleza, ukuchithwa kwamaminerali nakho kwenzeka. Izilwane zasolwandle zisebenzisa la ma-ion ukuze zenze amagobolondo azo namathambo ekugcineni abe yi-limestone nokunye okubanjwayo. Itshe lekhabhoni.
Ukugcinwa kwekhabhoni kuyindlela edingekayo yokunciphisa inani le-carbon dioxide emkhathini. Ngaphandle kwayo, mancane amathuba okuthi sifinyelele “izinjongo zethu zekhabhoni” futhi sigweme imiphumela emibi kakhulu yenhlekelele yesimo sezulu.
Ososayensi bahlola nokuthi isetshenziswa kanjani imfucuza evela kwezinye izimboni zezimayini njenge-nickel, ithusi, idayimane neplatinamu ukuze kuthathwe ikhabhoni. Balinganisela ukuthi kungase kube nezinto ezanele zokumisa isikhutha esike sakhishwa abantu, nokunye okwengeziwe, kubika i-Bird.
Manje, izinto eziningi zimi emadwaleni aqinile angakaze abonakale emoyeni, okuzoqala lokho kusabela kwamakhemikhali. Kungakho ososayensi abafunda ukukhishwa kwekhabhoni bezama ukuthola izindlela zokwandisa ukuchayeka nokusheshisa le mpendulo evame ukunensa ukuze baguqule imfucuza yasezimayini ibe umgqugquzeli onamandla wokumelana nenkinga yesimo sezulu.
Umbiko we-MIT uchaza ukuthi kungakanani ukungenelela okuhloliwe ngokumba izinto zokwakha, ukuzigaya zibe yizinhlayiya ezicolekile, bese zisakazwa zibe izendlalelo ezincanyana, bese zisatshalaliswa emoyeni ukuze kwandiswe ukuvezwa kwendawo yokusabela ye-carbon dioxide material. Ezinye zidinga ukushisa noma ukwengeza i-asidi ku-compound. I-Eos ibika ukuthi abanye baze basebenzise amacansi amagciwane ukuze baqalise ukusabela kwamakhemikhali.
"Sibheke ukusheshisa le nqubo futhi siyiguqule isuka enqwabeni yemfucumfucu ye-asbestos ibe idiphozithi ye-carbonate engenangozi ngokuphelele," kusho isazi se-geomicrobiology uJenine McCutcheon, ozibophezele ekuguquleni imsila ye-asbestos elahliwe ibe yi-Magnesium carbonate engenabungozi. Ama-Gymnasts nabaqwali bamadwala basebenzisa impahla yempushana emhlophe ukuze bathuthukise ukubamba.
URoger Aines, umqondisi woHlelo LweCarbon eLawrence Livermore National Lab, utshele iMIT Technology Review: “Leli yiThuba elikhulu, elingathuthukisiwe, elingaqeda isikhutha esiningi.”
Umbiko uqhuba uthi abasekeli balelisu elisha bakhathazeke ngezindleko nemikhawulo yomhlaba. Uma kuqhathaniswa nezinye izindlela ezinciphayo njengokutshala izihlahla, le nqubo ibiza kakhulu. Kungase futhi kudinge inani elikhulu lomhlaba ukuze kusatshalaliswe izinto ezintsha ezanele ezingambiwe ukuze kuncishiswe kakhulu ukukhishwa kwekhabhoni, okwenza kube nzima ukukhuphuka.
U-Bird uphinde waveza ukuthi yonke le nqubo ingase idle amandla amaningi, futhi uma ingakalwa ngokucophelela, ingase isuse izinzuzo zokubamba ikhabhoni ezama ukuyidala.
Okokugcina, kunezinto eziningi ezikhathazayo ezizungeze ubuthi balezi zinto kanye nokuphepha kokuzisingatha. I-MIT Technology Review yabonisa ukuthi ukusabalalisa uthuli lwe-asbestos emhlabathini kanye / noma ukulusakaza othulini ukuze kwandiswe ukujikeleza komoya kubangele izingozi zokuphepha kubasebenzi abaseduze nezakhamuzi.
U-Bird uphethe ngokuthi ngaphandle kwalokhu, uhlelo olusha lungaba "inketho ethembisayo yokwengeza ezinye izixazululo eziningi, ngoba sonke siyazi ukuthi ngeke kube khona ikhambi lenkinga yesimo sezulu."
Kunezinkulungwane zemikhiqizo laphaya. Abantu abaningi bazokwenza into efanayo ncamashi, noma icishe ifane ncamashi, kodwa ngokuhlukana okucashile. Kodwa eminye imikhiqizo iqukethe izinto ezinobuthi ezingase zilimaze thina noma izingane zethu. Ngisho nomsebenzi olula wokukhetha umuthi wokuxubha ungasenza sikhathazeke!
Eminye imiphumela yesimo sezulu esibi kakhulu ingabonakala-ngokwesibonelo, ingxenye yommbila oyisicaba e-Iowa yasala ngemuva kokuthi i-Midwestern United States ishaywe kanzima ngo-August 10.
