Alright, if you want to recycle it, just wash it in a sep funnel with some dilute HCl to remove any residual product, (which can then be basified and extracted, and gassed again) then wash the np with some dilute base to get rid of any acid you think might be there, (probably not necessary) then dry and distill. Easy.
