Crest Foam - Elimination of Methylene Chloride Use in Manufacturing Process. OTA 1997.

Crest Foam of Newburyport, Massachusetts recently embarked on an ambitious program to eliminate the use of volatile organic compounds (VOCs) in the firm's polyurethane foam process. The company eliminated the use of 190,000 lbs./year of methylene chloride by installing an innovative foam manufacturing process called the "Cardio Process". The Cardio Process uses CO2 instead of methylene chloride or CFC-11 as the auxiliary blowing agent. By making this change, Crest Foam avoided the need to install costly air pollution control equipment or reduce its production of foam products, either of which would have threatened the long-term survival of the facility.
