Description:
The catalog of Industrial Process Profiles for Environmental Use was developed as an aid in defining the environmental impacts of industrial activity in the United States. Entries for each industry are in consistent format and form separate chapters of the study. The gypsum and wallboard industry comprises operations which mine gypsum deposits and process the mined gypsum rock into crushed or pulverized uncalcined gypsum, pulverized calcined gypsum and a diversity of prefabricated gypsum-core board products. One chemical tree, one process flow sheet and nine process descriptions have been prepared to characterize the industry. Within each process description available data have been presented on input materials, operating parameters, utility requirements and waste streams. Data related to the subject matter, including company, product and raw material data, are included as appendices.
