Iingcali zenzululwazi zihlola indlela yokusebenzisa i-asbestos kwinkunkuma yasemigodini ukugcina isixa esikhulu sekharbon diokside emoyeni ukunceda ukujongana nengxaki yemozulu.
I-Asbestos yiminerali yendalo eyayifudula isetyenziswa ngokubanzi njengendawo yokugquma ubushushu kunye nokunqanda umlilo kwizakhiwo.Olu setyenziso lwaziwa kakhulu ngeempawu zalo zomhlaza, kodwa lusetyenziswe kwiziqhoboshi zeemoto ezithile kunye nesilingi kunye neethayile zophahla kushishino lweklorine.Nangona ngoku amazwe angama-67 ekuthintela ukusetyenziswa kwefiber materials, iUnited States ayikho enye yazo.
Ngoku, abaphandi bagxininise kwiintlobo ezithile ze-asbestos ene-fibrous, eziyimveliso yenkunkuma evela kwimigodi.Ngokutsho kwe-Eos, umgangatho ophezulu kakhulu owenza i-asbestos ibe yingozi ekuphefumleleni nayo iyenza ixhobe kakuhle ukubamba amasuntswana ekharbhon diokside edada emoyeni okanye inyibilikiswe yimvula.Ingxelo inika iinkcukacha zokuba indawo ephezulu yeefayibha izenza "zisebenze kakhulu kwaye kulula ukuziguqula" zibe ziikhabhoni ezingeyongozi xa zixutywe necarbon dioxide.Le nkqubo yenzeka ngokwemvelo xa i-asbestos ibonakaliswe kwiigesi ze-greenhouse.
Ngokuka-MIT Technology Review, ezi zinto zizinzileyo zinokuvala iigesi ze-greenhouse kangangezigidi zeminyaka kwaye zibonakalise ukuba lukhetho olusebenzayo lokufunxa izixa ezikhulu zekharbon diokside emoyeni.Izazinzulu zinethemba lokuphelisa ukukhutshwa kwekhabhoni "enkulu" kwimisebenzi yezemigodi kuqala, kwaye emva koko zandise iinzame zokunciphisa ukukhutshwa kwegesi ye-greenhouse.
UGregory Dipple, umphandi okhokelayo kwintsimi, uxelele I-MIT Technology Review: "Kwiminyaka elishumi ezayo, imigodi ye-decarbonizing iya kusinceda ukuba sakhe ukuzithemba kunye nobuchule ukwenzela ukunciphisa ukukhutshwa.Kwaye imigodi yokwenyani iyenziwa. ”
NgokukaKottke Ride Home Podcast host uJackson Bird (Jackson Bird) unike ingxelo yokuba xa ezi zinto zingena elwandle ngokubaleka, ukugaywa kwezimbiwa nako kuyenzeka.Izinto eziphilayo zaselwandle zisebenzisa ezi ion ukwenza amaqokobhe kunye namathambo azo ekugqibeleni abe yi-limestone kunye nokunye okubanjwayo.Ilitye lekhabhoni.
Ukugcinwa kwekhabhoni yindlela efunekayo yokunciphisa umthamo we-carbon dioxide emoyeni.Ngaphandle kwayo, akunakwenzeka ukuba sifezekise "iinjongo zethu zekhabhoni" kwaye siphephe iziphumo ezimbi kakhulu zengxaki yemozulu.
Iingcali zenzululwazi zikwaphonononga indlela yokusebenzisa inkunkuma evela kwamanye amashishini emigodi afana nenickel, ikopolo, idayimani kunye neplatinam ukubamba ikhabhoni.Baqikelela ukuba kusenokubakho izinto ezaneleyo zokuphelisa yonke ikharbon diokside ekhe yakhutshwa ngabantu, nokungakumbi, unikela ingxelo yeNtaka.
Ngoku, izinto ezininzi zimiliselwe kumatye aqinileyo angazange abonakale emoyeni, nto leyo eya kuqalisa ezo ntshukumo zemichiza.Yiyo loo nto izazinzulu ezifunda ukususwa kwekhabhoni zizama ukufumana iindlela zokonyusa utyhileko kunye nokukhawulezisa le mpendulo idla ngokucothayo ukuze kuguqulwe inkunkuma yasezimayini ibe ngumkhuthazi onamandla wokuchasana nengxaki yemozulu.
Ingxelo ye-MIT inika iinkcukacha ukuba mangaphi amangenelelo avavanyiweyo ngokugrumba izinto, ukuzigaya zibe ngamasuntswana acolekileyo, emva koko asasazeke abe ziingqimba ezicekethekileyo, emva koko asasazeke ngomoya ukonyusa ukuvezwa Indawo yokusabela kumphezulu we-carbon dioxide.Abanye bafuna ukufudumeza okanye ukongeza iasidi kwikhompawundi.U-Eos unikela ingxelo yokuba abanye bade basebenzise iimethi zebhaktheriya ukuqalisa ukusabela kwemichiza.
"Sijonge ukukhawulezisa le nkqubo kwaye siyiguqule kwimfumba yenkunkuma ye-asbestos ibe yidiphozithi ye-carbonate engenabungozi ngokupheleleyo," watsho i-geomicrobiologist uJenine McCutcheon, ozinikele ekuguquleni i-asbestos tailings eshiywe ibe yi-Magnesium carbonate engenabungozi.Iigymnasts kunye nabakhweli bamatye basebenzisa izinto ezimhlophe zomgubo ukuphucula ukubamba.
URoger Aines, umlawuli weNkqubo yeCarbon eLawrence Livermore National Lab, uxelele I-MIT Technology Review: "Eli liThuba elikhulu, elingaphuhliswanga, linokuphelisa i-carbon dioxide eninzi."
Ingxelo iqhubeka ithi abaxhasi besi sicwangciso esitsha banenkxalabo malunga neendleko kunye nezithintelo zomhlaba.Xa kuthelekiswa nezinye iindlela zokucutheka ezifana nokutyala imithi, le nkqubo ineendleko ezinkulu.Kusenokufuna umhlaba omkhulu ukusasaza izinto ezintsha ezaneleyo ezivunjululweyo zokunciphisa kakhulu ukukhutshwa kwekhabhoni, nto leyo eyenza kube nzima ukunyusa.
Intaka iphinde yabonisa ukuba yonke inkqubo ingadla amandla amaninzi, kwaye ukuba ayilinganiswanga ngokucokisekileyo, inokucima izibonelelo zokubamba ikhabhoni ezama ukuyidala.
Ekugqibeleni, kukho iinkxalabo ezininzi ezijikeleze ubutyhefu bezi zinto kunye nokhuseleko lokuphatha.Uphononongo lweTekhnoloji yeMIT lubonise ukuba ukusabalalisa uthuli lwe-asbestos emhlabeni kunye / okanye ukusabalalisa eluthulini ukunyusa ukujikeleza komoya kubangele ubungozi bokhuseleko kubasebenzi abasondeleyo kunye nabahlali.
U-Bird ugqibe kwelokuba ngaphandle koku, inkqubo entsha inokuba "lukhetho oluthembisayo lokongeza ezinye izisombululo ezininzi, kuba sonke siyazi ukuba akusayi kubakho nyango yengxaki yemozulu."
Kukho amawaka eemveliso phaya.Abantu abaninzi baya kwenza kanye into efanayo, okanye phantse ifane, kodwa ngokwahlukana okufihlakeleyo.Kodwa ezinye iimveliso zineekhompawundi eziyityhefu ezinokusenzakalisa thina okanye abantwana bethu.Kwanomsebenzi olula wokukhetha intlama yamazinyo unokusenza sizive sixhalabile!
