Disposal of bottle tumbling waste water/foam

[Haldy]

I just began tumbling with a new machine that a bottle-collector friend put together for me. My question deals with the safe/proper way to dispose of the "waste water/sludge/foam" that is a by-product of the process. I live in a development, so I can't just dump the stuff anywhere I want. I see the Jar Doctor states in his literature that it is OK to flush the stuff down the drain, but my wife would kick my butt if I did any damage to our plumbing and I wouldn't be too happy myself! Is anyone currently washing the stuff down their drain? Will this stuff kill my grass, if I pour it onto the ground? Is it considered toxic? Any advice from the experienced tumblers out there will be greatly appreciated. Thank you in advance for your help!

Aluminum oxide is considered a hazardous material but most of the risk seems to be in breathing it.

Carbide is pretty inert.

Not sure about cesium based polishes.

I dump mine down the septic system! I used to do it in the unused bath tub, but it reaves a ring that is VERY hard to clean. Now I do it in the kitchen sink (stainless steel) and no clean up problems. I have had no pipe problems or septic troubels, That's my 2 cents
