facturing ceramic substrates replaced methanol with deionized water. The estimated impact is a savings of $739,000 for every 100,000 pounds of glass frit, a raw material, used in production, a reduction in methanol emissions of 6,000 pounds, and improved cycle time of 30%.Copley Square Hotel A prominent hotel, it created an aggressive environmental program that provides a foundation for ISO 14001 registration.
