Abstract
ABSTRACT
The Hewlett-Packard Company, Colorado Springs Division, operates a twelve-hundred-square-foot per day printed circuit board manufacturing facility to supply the local divisions with the necessary boards to build their products. The original manufacturing processes were extremely chemical intensive, and resulted in the emission, or potential emission, of pollutants into all environmental media. As concerns grew about worker safety, chemical disposal costs and liabilities, and keeping up with the state-of-the-art manufacturing technologies, many of these chemical-intensive processes were replaced by processes that used less toxic chemicals, or chemicals that produced fewer by-products for disposal. The specific examples selected for this paper represent a broad spectrum of approaches to waste reduction, including improved waste treatment processes, chemical substitutions, equipment substitutions, and totally new concepts in printed circuit board manufacturing technology.
