Used Solvent Testing and Reclamation, S Volume I: Cold-Cleaning Solvents by

Large amounts of waste solvent are generated each year at many Department of Defense (DOD) installations. Stand-ard practice at these sites has been to discard spent solvents. However, increasingly stringent environmental regulations, coupled with the soaring cost of waste dispor- ' and new solvent purchase, have led DOD to seek safe, cost-effective methods of managing waste solvent. Some DOD installations are reclaiming used solvents rather than discarding them. Reclamation is feasible be-cause the solvents usually do not break down chemically during the cleaning operations for which they are used. However, this type of recycling has seen limited success in the past due to thie lack of scientific tests and criteria for-I judging a solvent as spent.
