What are the advantages of using CO2 over traditional dry cleaning solvents?
How? Wet cleaning processes use water and detergent to clean clothes that typically require dry cleaning. Liquid carbon dioxide technology is non-toxic, non-combustible, and does not contribute to hazardous air pollutant (HAP) and volatile organic compound (VOC) emissions.
What is supercritical carbon dioxide used for?
Supercritical carbon dioxide is used to remove organochloride pesticides and metals from agricultural crops without adulterating the desired constituents from the plant matter in the herbal supplement industry.
What products contain perchloroethylene?
Tetrachloroethene is found in consumer products, including some paint and spot removers, water repellents, brake and wood cleaners, glues, and suede protectors.
