The premise for Carbon Cycle’s technology is to permanently capture large amounts of CO2 in a process that produces precipitated calcium carbonate (PCC) and ammonium sulphate fertilizer. With a new technology, Carbon Cycle’s process uses dramatically less energy and creates a carbon-negative outcome rather than the current carbon-positive methods currently used. With low energy use and high efficiency capabilities, CO2 is reduced in a process that creates valuable products for both paper and agricultural industries.

The process created by Carbon Cycle utilizes otherwise-wasted CO2 and permanently mineralizes it into PCC during the process of creating ammonium sulphate fertilizer. It replaces two carbon-intensive processes into a single carbon-negative process. The PCC can then be used in a variety of applications, including the paper products industry, while the fertilizer can be used in the agriculture industry.
