I guess if you just keep them wet all the time - till the final disposal - the ignition will not occur.
For waste management try to explore the regulations of that particular country where you at, and/or to look for experiences in similar plants.

What is the process? I am very familiar with amines in refineries and have never seen this. I would ask your carbon supplier to do a thorough analyses of the spent material to determine why it is bursting into flames. I would review the change out procedures to see if the vessel is being purged properly prior to dumping.

Matter seems to me of

contamination with some pyrophoric materials (Zuberberg's keeping water wet guidance is pertinent)

either produced during the reactions un-noticeablely

or finding their way (from some other upstream sources) into the charcoal bed
Another possibility is that CS2(Carbon Disulphide generation and retention in the bed)

Since all the Pyrophoric materials are susceptible to very slow un-noticed oxidation in ambient air contact at temperatures as low as around 54 Celsius.
