SAGE is an expert system for selecting alternative materials and processes for cleaning of metals, electronics, plastics, and stripping of paint. SAGE recommends solvent replacements in cleaning and degreasing operations. It leads the user through a question-and-answer session. The user's responses allow the system to develop a list of alternative chemistries and processes. The user may then review brief descriptions of the alternatives on the computer screen. If any of the alternatives are of interest, the user may request SAGE to generate a detailed report for each. The report includes general information, safety/environmental concerns, industrial case studies for the selected alternative, and information on state technical assistance programs in the user's geographical location that can provide additional information.
