Ka ho sebelisa mekhoa e tsoetseng pele ea ho thatafatsa CO2, taolo e tiileng ea boleng, le mekhoa e tšoarellang, re fana ka molekane ea tšepahalang oa phepelo bakeng sa katleho ea hau ea nako e telele.
Na u se u ikemiselitse ho ntlafatsa phepelo ea hau ea thepa?
Haeba u na le lits'oants'o tsa tekheniki kapa litlhoko tse ikhethang, sehlopha sa rona sa boenjiniere se ikemiselitse ho fana ka tlhahlobo e hlakileng ea ho khoneha le khotheishene ea tlholisano. Re sebetsa ka thata ho fetolela mehopolo ea hau ea moralo ho likarolo tsa tšepe tsa boleng bo holimo, tse bolokang chelete e ngata.
Ikopanye le rona kajeno ho buisana ka litlhoko tsa projeke ea hau le ho fumana hore na tharollo ea rona ea sodium silicate casting e ka ntlafatsang tšebetso ea sehlahisoa sa hau joang.
