Usually the water is recycled by water treatment plants before it is discharged into rivers. Industries produce much more water that must be cleaned and recycled. They also use other liquids for cleaning and for making chemicals. These liquids cannot be discharged to streams and rivers and are expensive to recycle. There are other ways to clean things and to make useful chemicals, using carbon dioxide.
Carbon dioxide is produced by plants, and is found in many things, including soft drinks.
At high pressure carbon dioxide becomes a useful liquid that can be recycled and used to take the place of precious water. We are scientists and engineers that explore and invent new ways to make carbon dioxide useful. We work at different universities in two states. We work with scientists in industries and some of the things we have invented are already available for you to use. This web site is about our work and who we are.
