Carbon Cycle Process


The Carbon Cycle process reacts gypsum, ammonia and carbon dioxide captured from industrial sources to produce precipitated calcium carbonate and ammonium sulphate. It incorporates an innovative new low capital cost technology that allows the reaction to occur at ambient temperature and pressure by efficiently containing sorbent vapour within a flowing gas stream. We hold the Intellectual Property rights to this technology. Other elements of our process are based on established low-risk turnkey solutions.


Our process takes low cost inputs and otherwise-wasted carbon dioxide and makes important global commodities. It costs less and uses less energy than existing production methods. It replaces two existing carbon intensive processes with a single carbon negative process and delivers economic benefits at the same time as tackling climate change. The unique vapour containment technology that sits at the core of the process will have range of other applications in the future.


The main products are valuable global commodities with growing markets and a wide range of applications. Precipitated calcium carbonate is used in the paper, plastics and pharmaceuticals industries. Ammonium sulphate is used as a fertiliser in locations with alkaline soils. In addition some jurisdictions provide a supplementary revenue stream in the form of credits or avoided payments for the capture of carbon dioxide that would otherwise have been released into the atmosphere.
