Source reduction would be a reduction in the amount of solvent used; in this case, no changes are made to eliminate or reduce the use of the solvent. An example of out‐of‐process recycle would be to send the solvent off‐site to be recycled. End‐of‐pipe treatment would consist of treating the solvent to make it less toxic before disposing of it. In this case, the solvent is filtered and returned to the same equipment that created the dirty solvent. Therefore, this is in‐process recycling.
