Converting waste streams into valuable chemicals
We are redefining chemical manufacturing so that vital chemicals are produced on-site in our modular units at lower cost than legacy industries.
Rushnu’s thermochemical process captures industrial carbon emissions and waste heat to produce high purity chlorine and carbonated minerals directly on sites where they are used.
Rushnu’s technology makes chlorine cheaper, safer, and cleaner.
Why chlorine? Chlorine is one of the most strategically important chemicals in the global economy.
Chlorine is used everywhere.

Wastewater Treatment
We upgrade biogas into renewable natural gas for on-site heat generation. Simultaneously, we produce bleach and calcium carbonate supplying purification and alkalinity for use on site.

Steel
Steel production generates significant flue gas emissions. We capture the carbon dioxide from these emissions while supplying the hydrochloric acid used for steel pickling.

Semiconductor Fabrication
Every ton of polysilicon requires 4.5 tons of chlorine and generates 70 tons of carbon emissions. We produce chlorine without emissions and support a shift toward domestic semiconductor production.

Rare Earth Mining
The mining sector is set to expand dramatically by 2040 to meet energy transition demand. From rare earth minerals to lithium, we help mines cut carbon emissions while producing the hydrochloric acid needed for metal leaching.

Pulp and Paper
We produce hydrochloric acid for chlorine dioxide generation, enabling bright, high-purity paper. Our precipitated calcium carbonate (PCC) has been independently verified at greater than 98% purity by Imerys.

PVC Plastic
We partner with large carbon emitters across the Gulf Coast such as refineries and chlor-alkali facilities to supply the building blocks for polyvinyl chloride (PVC) plastic.
Building a cleaner future with domestic and global industrial leaders.
