Beneficial Co-Utilization of Agricultural, Municipal and Industrial by-Products

The potential for blending residuals to create valuable products that are publicly accepted is an example of recycling at its best. Previously, much of the research done on reuse of residuals has centered on potential negative effects. Generally, blending of materials has been done in a relatively haphazard fashion. There is a growing understanding that residuals can be deliberately mixed for specific end uses. This is the initial phase of transition from residuals disposal to product development. The XXII Annual Beltsville Symposium focused on the range of factors that need to be taken into account for any co-utilization program to be successful. The proceedings include research reports as well as reports from the private sector. Potential uses for co-utilization products as well as areas requiring more research are outlined.
