Says that the EK-CryoFuel mixtures are biodegradable and nontoxic.

Agreed. Most PC liquid cooling fluids are biodegradable and water-based, so they can be easily disposed of. Just do so in a location so pets or children do not have the ability to ingest - they typically are not toxic, but no point in taking that risk.
