Some of the most rigid architectures built by nature, be it trees or coral reefs,
sequester an abundance of CO2 molecules in their environment and convert
them into the building blocks of complex organic structures. Second to water,
concrete is one of the most widely used resources on the planet, mainly in the
construction. The company Blue Planet mimics the mineralization process of
marine ecosystems to convert carbon dioxide into carbon-negative buildings and
infrastructure materials.
“We believe human contributions to Earth’s atmospheric CO2 levels is about 35
billion tonnes per annum, and growing. More than half of this CO2 (22 billon
tonnes) could be prevented from release into the atmosphere using the
production of limestone aggregate in place of the currently mined aggregate.”
