We are currently facing a climate emergency in which we have to take action to fight climate change. The impact of climate change will be far worse if we do not do anything now.


To tackle this problem, we need to curtail current emission levels and decrease the carbon dioxide (CO2) in our atmosphere with negative emission technology.


At Carbon Mining, we believe our patented Annulus Core Reactor (ACR) is the most effective way to treat captured CO2.  ACR locks captured CO2 in a reactant bicarbonate solution which is then pumped to a second reactor and mixed with other additives to create valuable commodities. 


ACR can be built to size to suit any CO2 emission volume that a facility emits. ACR requires minimal energy to run and only water and non-corrosive chemicals are needed in the process. ACR can be operated to produce different product outputs. This can be achieved by using different feedstocks of non-corrosive chemicals. 

So what is ACR? ACR is a patented chemical process that converts CO2 into useful products such as fertilizers and calcium carbonate. ACR can be built to size and attached to any facility that emits CO2. ACR requires a continuous flow of carbon dioxide emission which can be delivered directly from a production facility into the ACR reaction chamber. ACR can accept this input with other contaminants such as sulphur oxide and nitrous oxide present being the types of contaminants typically present in smoke-stack or combustion exhaust venting. These contaminants are chemically absorbed in the reaction chamber by a process of oxidation. Any increase in acidity created by this oxidation process is controlled automatically by the ACR array by correcting the PH.



Production commences with the CO2 emission gas stream being cooled and humidified before the introduction of anhydrous ammonia (NH3) into the emission gas stream as it enters the ACR reaction chamber. This vapour mix commences reacting as it flows into the ACR reaction chamber which is already charged with water at a pH of 9. The reacting gas mix is dispersed into the circulating solution via the ACR chamber.


The liquid is prop-driven to circulate continuously within the reaction chamber. The emission gas mix is dragged down through the draft tube dissolving the bubbles. The inflowing dissolving gas progressively increases in concentration in the reactor chamber.  


The reaction that is occurring in the ACR is:

 CO2 + NH3 + H2O --> NH4HCO3


Once the solution is fully saturated to an appropriate concentration of ammonium bicarbonate to manufacture the high-value commodities such as ammonium/carbon liquid fertilizer, this reactant solution is then pumped to a second reaction chamber to be mixed with another reactant to produce the end product of interest.

ACR operates as a continuous batching system.  Each installation is comprised of at least two ACR reactor chambers installed in series and alternating between each other in tandem.  The first chamber is in production mode while the other fills with water and remains on standby.  Upon completion of the production cycle, the first chamber commences a decanting process to upstream processes that yield the product defined by the additives chosen.  At that decanting changeover point, the second chamber commences receiving the modified exhaust flue emissions and the process commences anew. The first chamber is then refilled with water after decanting and stands ready to alternate with the second chamber when it has completed its cycle.


The reactant solution from the first reactor is then pumped to a second reactor where either the ammonium bicarbonate/ ammonium sulphate can be put through a crystallization plant or the base liquor can be used as a precursor for the manufacturing of liquid fertilizers. These two production choices are mutually exclusive.


There is no limitation on high grade products which ACR can create.  These products are highly valuable in today’s market.  They also require a lot of energy to manufacture.  We believe ACR can reduce the emissions of carbon dioxide greenhouse gas into the atmosphere as well as making the following commodities economically:

  • Bulk Liquid Ammonium Bicarbonate Fertiliser

  • Crystalline Ammonium Sulphate

  • NPK and Potassium Sulphate Fertilizer

  • Super-Hi-Grade, Super-White Pharmaceutical Grade Calcium Carbonate

  • Crystallized Ammonium Nitrate for use in Explosives

  • Ammonium Nitrate Solution as a Precursor for High-Grade Fertilizers

  • Hi-Grade Precipitated Calcium carbonate

  • Sodium Bicarbonate Precipitate

  • Super-Saline Water Conversion (Desalination) to yield

    • Sodium Bicarbonate

    • Ammonium Chloride
