Is antifreeze toxic to the environment?
Potential Environmental Impacts: Antifreeze can pollute groundwater, surface water, and drinking water supplies if dumped, spilled or leaked, and is harmful to marine and aquatic life.
Antifreeze with propylene glycol, which is less toxic, and is marketed as nontoxic, is recommended for use..
Is there a non toxic antifreeze?
Propylene glycol is considerably less toxic than ethylene glycol and may be labeled as “non-toxic antifreeze”. It is used as antifreeze where ethylene glycol would be inappropriate, such as in food-processing systems or in water pipes in homes where incidental ingestion may be possible.
Are there any alternatives to antifreeze?
ASTM International recently announced standards wherein the use of Glycerin within antifreeze and engine coolant products is seen as a much more environmental friendly and cost-effective alternative than Ethylene Glycol, which is the most prevalent component today.
Is there a pet safe antifreeze?
SIERRA® Antifreeze/Coolant is formulated with PG rather than ethylene glycol – the base for traditional antifreeze. Because of its PG formula, SIERRA® Antifreeze is less toxic and therefore safer for people, pets, and wildlife than conventional antifreeze.
Can I dump antifreeze on the ground?
Antifreeze has a sweet taste that can attract pets and small children. So do not pour antifreeze on the ground outdoors and do not put it in the garbage. Also, never dump antifreeze down a household drain or toilet if you have a septic system.
Does antifreeze breakdown over time?
In general, coolants degrade over time as the ethylene glycol breaks down into primarily glycolic and formic acids. … Glycol breakdown products are acidic and contribute to a drop in pH. Once a coolant has degraded, due to glycol breakdown and pH drop, engine metals are at risk for corrosion.
