Green/Alternative Solvents

Solvents often cause the greatest environmental impacts of a process or product because the mass of solvent is greater than the mass of all other components combined. The greenest solvent is the solvent that makes the product or process have the least environmental impact over its entire life cycle. A solvent may be green for one application and not for another. Classes of solvents include water, organic solvents, supercritical fluids, gas-expanded liquids, ionic liquids, liquid polymers, deep eutectic solvents, and switchable solvents.
