Carbon Dioxide (CO2) Technology Platform

We Are Leaders in CO2 Applications.

The Tersus Solutions CO2 platform offers amazing capabilities - this is in large part due to the amazing nature of CO2. When pressurized, Carbon Dioxide (CO2) becomes a liquid (LCO2) and at even higher pressures become super-critical (scCO2). By leveraging these three phases of CO2, many processes once considered impossible can be achieved. However, due to the high pressures involved, the access to R&D is limited, so the applications are rare.

At Tersus Solutions we have found success using our platform to put Carbon Dioxide to work in many applications. R&D has been performed on many more use cases, and are in various stages of development. Many times just needing the right "go to market" partner.


Our R&D is different.

Our R&D is different. Most CO2 R&D is done on small "bench top" scale. With our existing platform available in various sizes we are able to perform tests at or closer to scale. Our many years of experience working with the medium gives us the ability to avoid challenges you would find in your first time harnessing the power of CO2.

At the heart of our platform is the abilty to recycle and purify CO2. The CO2 used is not created for the process but rather by-products of other industries. Our use of others waste gas funds the capture and prevents release into the environment.

Past & current R&D projects.

The proven CO2 platform along with know how of the team at Tersus Solutions can develop completely new methods to approach traditional process, as well as open doors to those once thought impossible.

Raw Fiber Production

Beyond down and feather recycling, we have integrated CO2 into Wool production to eliminate water in the process from raw wool to a ready to use yarn. The process not only produced excellent results but created a quality lanolin oil by-product. 


For Hemp fiber production we developed a CO2 degumming process, and demonstrated a break down of the lignin to allow easy seperation of the fibers.

Coating Application

Successfully applied Durable Water Repellant using CO2 in the absence water and the high temperatures normally needed. This creates the ability to apply DWR after contruction or re-apply after use.

Medical Applications

Successfully achieved set cytotoxicity standards on medical implantables prior to sterilization

Removing mill oils & other contaminants on medical products including sutures and implantables

Our CO2 Platform's Major Milestones.
