[Text] How to dispose of bad pickle juice and herbs?

I made some homemade pickles, and a couple of the "empty" jars (they still have garlic, dill, pepper, spices, and onions in them) have gone bad. The jars are starting to grow mold so it's time to toss them.

Every post or web page I find online talking about this says the same thing: reuse reuse reuse! (Unless they've gone bad) but none actually tell me about a safe alternative to just pouring this down the sink or toilet because of this.

Does anyone know? Is safe to toss outside due to being mostly if not completely natural or do I need to strain the old stuff out and throw it out?

Please help!!!
