CO2 Mineralization

Presented by: Victoria

co2 bicarbonate
CO2 Bicarbonate
  • Calcium Bicarbonate
  • Ca(OH)2 + CO2 → CaCO3 + H2O
  • CO2 + H2O «-» H+ + HCO3-
  • Or Sodium bicarbonate
  • CO2 + 2NaOH → Na2CO3 + H2O
implementation
Implementation
  • 1. The bacteria need to uptake CO2 (or it can use it’s own waste CO2)
  • 2. the bacteria need to be able to convert CO2  CaCO3
  • 3. The CaCO3 needs to leave the bacteria (so that you don’t have to kill the bacteria to collect the precipitate)
    • Would the bacteria get rid of the precipitate on its own?
breaking it down
Breaking it down
  • Maximizing CO2 uptake by bacteria (1 person)
  • Trying different methods of CO2 CaCO3
    • Make the bacteria produce a CO2CaCO3 converter enzyme (2 people)
    • Make the bacteria produce Ca(OH)2  (Ca + NaOH) so that when the CO2 was absorbed the calcium carbonate would just precipitate out. (2 people)
      • Can the bacteria survive with NaOH everywhere?
      • Make bacteria that can survive with NaOH everywhere.
co 2 solution sort of did it already

  • “The company has genetically engineered E. coli bacteria to produce an enzyme that converts carbon dioxide into bicarbonate. The enzyme sits at the core of a bioreactor technology that could be scaled up to capture carbon-dioxide emissions from power plants that run on fossil fuels.”
