I am by no means a Tree-Hugger but you need to dispose of used fluids properly, and dumping it in the sink/toilet is not one of them.

From Prestone.com: "Disposal of used antifreeze/coolant: Follow local laws and regulations. If required, dispose at facilities licensed to accept household hazardous waste. If permitted, dispose in sanitary sewer systems. Do not discard into storm sewers, septic systems or onto the ground."
So it's not safe to drink, it's not safe to pour into a septic tank, it's not safe to pour onto the ground, and if you take it somewhere, that place must be "licensed to accept hazardous waste." But it's okay to dump it down the toilet.
WTF?

The EPA, state, and local environmental agencies regulate a number of vehicular related waste streams including spent antifreeze. Used antifreeze has the potential to be a hazardous waste if lead content exceeds 5 parts per million.
Most states have regulations for the management and disposal of waste antifreeze, regardless of whether it is a hazardous waste. These regulations vary by state. Please contact the appropriate agency in your state for more information.
The federal government has enacted a number of environmental laws to protect the environment including The Superfund Amendments and Reauthorization Act (SARA) and The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).
Under the CERCLA regulations, spills of even small amounts of listed materials are reportable to local, state, and federal agencies. Ethylene glycol is regulated as a toxic material.
Call the Resource Conservation and Recovery Act (RCRA) Hotline at 1-800-424-9346 for information on determining if your antifreeze is hazardous."
