Since 2010, we have worked to improve textile processing in specialty fabrics and garments. With our partners, we are working to improve garment production and care while reducing water consumption and waste streams. We strive to set the new standard for textile production. 

Our Mission

We seek to redefine textile processing by replacing water with recycled carbon dioxide. To do so, we provide a superior processing platform that enhances textile performance while decreasing the resources needed to produce and maintain them. With our partners, we will design solutions that produce the most ecologically responsible textiles and garments in the world. At CO2Nexus, we strive to raise the standard of textile processing. 

The Problem

Textile manufacturing and maintenance is a series of incredibly water-intensive processes with pervasive inefficiencies. These processes require access to fresh (sometimes ultra pure) water and demand infrastructure for wastewater treatment and disposal. In many places around the world, textile processing competes with local communities for access to water, usually industry wins. 

We believe that textile production and maintenance does not have to be at odds with communities. CO2Nexus is making this a reality by innovative with liquid carbon dioxide to replace water in traditional textile wet processing. 

Quite simply, processing textiles and apparel requires huge amounts of energy and water – and both are in crisis.

The solution

TERSUS platform

proprietary machinery + CO2 chemistry + programming

Better performance, fewer resources -

this is our vision for textiles and apparel. 


CO2Nexus's TERSUS Solutions is a platform that integrates our proprietary machine with CO2-based chemistry and unique programming into a turn-key package to manufacture and maintain technical textiles. The TERSUS Solution enables companies to produce high performance textiles while reducing the environmental inputs needed (water and energy) and significantly reduces the waste streams that are found throughout the textile supply chain.

The most viable replacement for water in textile wet processing is carbon dioxide. Carbon dioxide is abundant, inexpensive and interacts with textiles and garments more gently than water. The TERSUS platform uses carbon dioxide in the liquid state because it results in the following:

  • Reduced use of chemicals and less waste - no contaminated wastewater
  • No residual solvents -pure end-product
  • Reduced processing costs
    • Quick
    • Less energy 
    • CO₂ is inexpensive and recyclable
  • Mild process conditions
    • Low temperatures
    • No oxygen
  • Versatile and tunable - applicable in many different industries
  • Safe, non-toxic, colorless, odorless, non-flammable

Over the course of repeated processing with carbon dioxide, benefits include down loft enhancement, improved/restored water repellency, without degrading color, size, fit consistency and expectations. 

With our partners, the CO2Nexus team continues to work on garment and environmentally friendly chemistries for a variety of textiles leveraging the properties of carbon dioxide.
