When growing algae that are 80% calcium carbonate as aragonite, what can be done with all the tonnes of material? Plenty. From building materials to additive manufacturing, aragonite can be used in ways that prevent the CO2 from getting back into the atmosphere. Calcium carbonate in general can be made into a carbon-negative cement for use in the construction industry. And there is also the 3D printing of calcium carbonate into a wide array of solid products.
What of the remaining 20%? The liquid extract contains naturally-produced chemicals that have already shown promise as antiviral and even anticancer compounds. We are seeking companies wishing to partner with us to develop out this resource. This would bring even more value to these algae, above and beyond that of calcium carbonate.
How many tonnes are possible? Have a look at the range map below to see where we could expand. Considering that cement is the most used product by weight in the world, there will surely be demand for more cement, and especially for its carbon-negative alternatives.
