Facts:

About biorock or mineral accretion technology

  • Biorock is the substance formed by electro-accumulation of minerals dissolved in seawater.
  • The technology works by passing a small amount of electrical current through electrodes in the water
  • As a result of the process, calcium carbonate is formed and coral larvae adhere to the CaCO3 and grow quickly.
