These objects were grown under water in a chemical process that parallels nature.

From 2022-present, I have been developing a process to create limestone from industrial waste and solar energy. The system is zero waste, circular, and follows principles of biomimicry. Because it sequesters carbon dioxide from the air and water, the limestone is potentially carbon negative.

The original process was developed by architect Dr. Wolf Hilbertz in the 1970s to mine the ocean. I am modifying it to avoid the ocean entirely and use industrial leftovers such as waste concrete.

By using local water obtained from rain, air, or tap, the end result is literally colored by the region in which it is created.

Limestone has fantastic potential for carbon capture on a mass scale.

The material can also be used for architecture and objects, potentially replacing mortar and concrete.

We will be experimenting with further uses and publishing our results.
