try to react those products into known ones, e.g. with nitric acid or by calcining (just in case some sort of hydrated carbocyanide was made).

A good trick is to package it up into say ten lots and simply mail it back and forth to yourself repeatedly. Eventually it will all be lost.

put it, and all your other chemical waste somewhere where you will never have contact with it again. good ideas are: public toilets, neighbours toilets, other countries,... :P
But I prefer to put em in a glass jar, label it toxic and just put it down somewhere in a dumpyard. they will not know who it belongs to, and you don't need to pay

According to the chemists of Max Gergel's era, "The solution to pollution is dilution."

So for small amounts of material, I agree with the other above. If you have anything that is organic and nasty, you could mix it into some other related consumer household waste and take it to a local "Household Hazardous Waste collection" site (we have them here sometimes) and let them deal with it. For instance, our area collects mercury thermometers and other related items, so you could probably give them a few ounces of mercury no problem. But if you show up with a 80 pound bottle, they might get a bit worried.

But I have seen pesticides, pool chemicals, photographic chemicals, and others dropped off OK. So if you have used DCM, and you obtained it from a bottle of paint stripper, you could probably put it back into the empty original bottle and say it is used paint stripper. That would all be true, and they will likely burn it with other halogenated waste. My biggest problem is that I usually would like to haul away some of the stuff people have turned in for disposal. I have seen some very valuable chemicals disposed of that way.
Someone shows up with an 80 pound bottle of mercury at MY doorstep not only would I be beyond words( read: extremely happy) but that bottle isn't going anywhere so long as I draw breath on this earth. but I digress. IF the waste is yours follow the advice and entomb the sucker. mark the block if you wish but , if nothing else, make a very big mental note which concrete block is what.
