DIY Co2 generator?
 

I built the DIY Co2 genenerator thing with the yeast and stuff and so far, it worked fine for about 6 weeks. Now i need to empty the contents and redue it but my question is, how do i properly dispose the contents. I know its not good to simply dump it outside, and im pretty sure that dumping it down the sink isnt good either. So where do I dispose of the contents? toilet maybe? THANK YOU!

There is no difference between dumping it in a sink and dumping it in the toilet.

Just throw it away in the trash.

I just don't want to cause a hazard to the environment
