Failures that Succeeded: Waste Management Treatability Studies

To select, design, and estimate costs for the best site-specific approach to remediate hazardous waste or convert waste to resources, treatability testing can be essential.  While at Michigan State University, I initiated the Anaerobic Digestion Research and Education Center to conduct laboratory proof-of-concept studies and bench-scale testing to obtain design data.  An example of a failure that succeeded from that facility entailed a biochemical methane potential assay on an industrial waste that appeared to be well suited for treatment using anaerobic digestion.  Digestion failed to significantly treat this waste due to its glycol content.  The result was success in preventing further efforts on this ineffective approach.  An example from my research at the EPA entails a treatability study on DDT contaminated soil.  Land treatment seeded with Phanerochaete sordida initially appeared to have potential.  However, DDT removal was determined to be the adsorption of DDT to humic material.
