Soda tshauv, tseem hu ua sodium carbonate, yog ib qho tseem ceeb ntawm cov ntaub ntawv raw khoom, dav siv nyob rau hauv ntau yam lag luam xws li iav, detergents, metallurgy, textiles, roj av, thiab tshuaj. Tuam Tshoj yog tus tsim khoom loj tshaj plaws hauv ntiaj teb thiab cov neeg siv khoom ntawm soda tshauv, suav txog li 50% ntawm lub ntiaj teb kev tsim khoom thiab kev thov¹. Txawm li cas los xij, Tuam Tshoj txoj kev lag luam soda tshauv tseem ntsib ntau yam teeb meem thiab cov hauv kev hauv cov ntsiab lus ntawm kev tiv thaiv ib puag ncig, kev sib tw ua lag luam, thiab kev tsim kho thev naus laus zis.
Ib qho kev sib tw tseem ceeb rauTuam Tshoj cov dej qab zib tshauv kev lag luamyog lub zog noj ntau thiab cov pa roj carbon emissions ntawm cov txheej txheem hluavtaws soda tshauv. Synthetic soda tshauv yog tsim los ntawm kev siv limestone thiab ntsev ua raw cov ntaub ntawv, uas yuav tsum tau ib tug loj npaum li cas ntawm cov thee thiab hluav taws xob. Raws li tsab ntawv ceeb toom los ntawm International Energy Agency (IEA), kev lag luam hluavtaws soda tshauv hauv Suav teb tau siv txog 70 lab tons ntawm cov thee thiab 140 billion kWh ntawm hluav taws xob hauv xyoo 2020, sib npaug rau 190 lab tons ntawm CO2 emissions². Qhov no ua rau muaj kev hem thawj loj rau ib puag ncig thiab kev nyab xeeb, nrog rau kev ua kom cov nqi tsim khoom thiab txo qhov kev sib tw ntawm Suav soda tshauv khoom.
Txhawm rau daws qhov kev sib tw no, Tuam Tshoj txoj kev lag luam dej qab zib tshauv tau tshawb nrhiav lwm txoj hauv kev tsim khoom uas siv hluav taws xob ntau dua thiab zoo ib puag ncig. Ib qho ntawm cov txheej txheem no yog cov txheej txheem tsim cov dej qab ntsev ntuj, uas siv trona, ib txwm muaj cov ntxhia uas muaj sodium carbonate, ua cov khoom siv raw. Natural soda tshauv ntau lawm muaj ntau yam zoo dua li hluavtaws soda tshauv ntau lawm, xws li kev siv hluav taws xob qis, qis carbon emissions, cov khoom zoo dua, thiab cov nqi qis dua. Txawm li cas los xij, natural soda tshauv ntau lawm kuj muaj qee qhov kev txwv, xws li qhov tsis txaus thiab tsis sib xws ntawm trona cov peev txheej, cov peev txheej siab thiab cov kev xav tau rau kev ua mining thiab ua trona, thiab tej zaum ib puag ncig cuam tshuam ntawm trona mining.
Lwm qhov kev sib tw rau Tuam Tshoj txoj kev lag luam dej qab zib tshauv yog qhov hloov pauv thiab tsis paub tseeb ntawm kev xav tau ntawm kev lag luam hauv tsev thiab thoob ntiaj teb. Soda tshauv xav tau yog ze rau kev txhim kho kev lag luam thiab kev lag luam ntawm ntau lub teb chaws thiab cheeb tsam. Piv txwv li, iav kev lag luam yog cov neeg siv khoom loj tshaj plaws ntawm dej qab zib tshauv hauv Suav teb, suav txog li 60% ntawm tag nrho cov kev thov. Txawm li cas los xij, cov iav xav tau cuam tshuam los ntawm cov khoom xws li kev tsim vaj tsev, kev tsim kho vaj tse, kev tsim tsheb, kev teeb tsa lub hnub ci, thiab lwm yam. Yog li ntawd, ib qho kev hloov pauv ntawm cov khoom no yuav muaj kev cuam tshuam loj rau cov dej qab zib tshauv xav tau thiab tus nqi. Ntxiv mus, Tuam Tshoj txoj kev lag luam soda tshauv tseem ntsib kev sib tw los ntawm lwm cov tuam txhab loj soda tshauv hauv ntiaj teb, xws li Tebchaws Meskas, Qaib Cov Txwv, Is Nrias teb, Russia, thiab lwm yam, uas muaj qhov sib txawv ntawm cov khoom siv ntuj tsim, cov cuab yeej tsim khoom, cov khoom zoo, thiab kev ua lag luam.
