The Design Internship in Pollution Prevention at The University of Tennessee is an honors capstone design course in which source reduction is incorporated into the design of industrial processes. In this activity pollution prevention through basic flowsheet development and equipment selection is emphasized rather than conventional treatment of the effluent waste streams. This activity was begun in 1990 and has involved 128 students and 32 projects. The number of projects per year has varied from 1 to 8. The output of each of these activities is a design report. An important benefit of these activities is an intensive process design experience for the students that emphasize pollution prevention concepts. The paper summarizes accomplishments and lessons learned.
