Ikharbon diokside isetyenziswa njani kwizinto zokuthambisa?

I-Nivea Men iza kukhupha iloshini enesithako esifunyenwe kwikharbon diokside

Ikharbhon dayoksayidi yaziwa njengerhasi esiyivelisayo xa siphefumla kwaye ingunobangela wokufudumala kwehlabathi, kodwa esingayaziyo kukuba sisithinteli-microbial esikhuselekileyo, i-antioxidant, anti-ukudumba, kunye nesivuseleli senkqubo yomzimba yokuzikhusela. Oku kuyenza ibe licandelo elisebenzisekayo kwiinkalo ezahlukeneyo, kubandakanywa necandelo lezithambiso.

Oku kubangele inkampani yaseJamani i-Beiersdorf, umenzi weempawu ezininzi ezidumileyo zokhathalelo lwezithambiso, kubandakanya i-Nivea, ukuba iqalise ikhrimu yokuqala yokhathalelo lwesikhumba equlethe i-carbon dioxide esetyenzisiweyo. Olu lutsha lwenziwa ukuba lwenzeke ngenxa yobuchwepheshe obubamba kwaye buphinde busebenzise ikharbon diokside, nto leyo eyenza kube lula ukuyifaka kwizithako zeNivea Men Climate Care Moisturizer yokhathalelo lwesikhumba samadoda.

Itekhnoloji ehambelana nokusingqongileyo:

Iimpawu ezininzi zamazwe ngamazwe zinika ingqwalasela eyongeziweyo ekuzinzeni nasekugcineni okusingqongileyo, nokuba kukukhetha izinto zokupakisha iimveliso zabo okanye izinto ezisetyenziswayo. Kwaye abanye baya phambili ngakumbi ngokusebenzisa iintlobo ezintsha zobugcisa ukuze bafeze olu sukelo. Oku koko kwenziwe liqela laseJamani iBeiersdorf, eliye lasebenza ukwenza into yokuthambisa eyenziwe ngekharbon diokside esetyenzisiweyo.

Obu buchwephesha bokusungula bunceda i-Nivea Men, eza kuphehlelela isithambiso sokuthambisa esinezithako ezifunyenwe kwikharbon diokside esetyenzisiweyo. Ngumceli mngeni iqela elijongene nawo ngokubanjwa kweCOXNUMX kunye nenkqubo yokurisayikilisha.

Ngokuqhelekileyo, ikharbon diokside yayiqokelelwa kwiindawo ezininzi, kuquka iitshimini zemizi-mveliso. Emva koko yacutshungulwa kwi-bioreactor kwaye yaguqulwa yaba yi-ethanol ye-cosmetic. I-Ethanol yenye yezinto ezisetyenziswa kakhulu kwizinto zokuthambisa, njengoko isebenza njenge-pore astringent kunye nesicoci solusu.Ikwanazo iimpawu zokukhusela ngenxa yesakhono sayo sokubulala i-microorganisms efana ne-bacteria, i-virus kunye ne-fungi. Oku kuyenza isetyenziswe ngokubanzi kuqulunqo lweemveliso zokhathalelo lomntu, iisepha, kunye neziqholo.

Imveliso yokuqala yohlobo lwayo:

Ukukhathazeka ngokuzinza kunye nokukhuselwa kokusingqongileyo kudlulela ekuqulunqweni kwemveliso, kodwa kunye nokupakishwa kwayo. Iqela le-Beiersdorf libhengezwe njengelingathathi hlangothi kwimozulu kwaye lenziwe kusetyenziswa umbane osuka kwimithombo ehlaziyekayo. Phantse ilawulwa ngokupheleleyo ngokwebhayoloji ngelixa ukupakishwa kwayo kunokuphinda isetyenziswe. Ngolu kuqaliswa, iqela laseJamani lifuna ukufezekisa iinjongo zalo zokunciphisa kakhulu ukukhutshwa kwekhabhoni ngo-2025.

Le mveliso iya kufumaneka kuhlelo olulinganiselweyo kwiimarike zaseJamani ukususela ngoJuni ozayo, kwaye iqulethe i-14 ekhulwini ye-ethanol ekhutshwe ngeendlela ezizezinye kwaye ayinayo i-particle yeplastiki, i-silicone, okanye i-oyile yamaminerali.

Ukuba le yimveliso yokuqala yokhathalelo lwesikhumba eyenziwe kwikhabhoni esetyenzisiweyo esetyenzisiweyo, ishishini leziqholo liceba ukuthatha ithuba lobu buchwepheshe ngokunjalo. UCoty, isigebenga saseMelika kwicandelo lokwenziwa kweziqholo, kutshanje uye wabhengeza ukuba uye wasebenzisa i-ethanol kwiifomyula zayo zesiqholo.

Kwenye indawo, i-California startup Newlight Technologies iphuhlise i-carbon-negative biomaterial eyaziwa ngokuba yi-Aircarbon, isebenzisa iigesi ze-greenhouse ekwenzeni iiglasi zamehlo kunye nempahla yesikhumba.
