Flammable liquid is how I’ve shipped the saturated solution.

Subject: [DCHAS-L] saturated picric acid solution
I discovered a bottle of saturated picric acid solution (opened in 1998) in a plastic-capped plastic bottle our chemical inventory. There is about 1-L of the solution left in the bottle. No-one needs it for staining, and I’d like to get
rid of it.
It looked like there was some drippage around the neck and cap, so I rinsed it for about 30 minutes under a stream of DI water until all of the material was gone. Then I opened the cap and wiped with a sponge around the cap and rinsed thoroughly
with DI water so that there was no apparent presence of material in the vicinity of the cap. After thoroughly cleaning the exterior of the bottle, I recapped it and put it back on the shelf until I can figure out what to do with it.
In the saturated solution form (I believe this means 1.2%), is there an inexpensive and acceptable way to dispose of it?
I have found dramatically conflicting reports of dangers associated with solutions of picric acid in my web searches.
Thanks,
Kyle Strode
