Waste Recyling Information
Antifreeze
Antifreeze is
most commonly composed of ethylene glycol, with corrosion inhibitors
and foam controllers added. Some antifreeze is composed of propylene
glycol because it is less toxic to humans and animals. During use,
antifreeze can pick up contaminants. If dissolved metal levels, such
as lead or cadmium, are high enough, used antifreeze may be hazardous
waste.
-
When
good antifreeze must be removed for repairs only, save it and return
it to the system after the repairs have been completed.
-
Separate spent antifreeze from other wastes.
-
Consider keeping antifreeze in two separate closed containers: one
marked “waste antifreeze only” for antifreeze that cannot be reused,
and one marked “usable antifreeze only” for antifreeze that can be
reused.
-
Recycle
your antifreeze through a recycling service.
|
-
Don’t
mix waste antifreeze with any other waste.
-
Don’t
mix propylene glycol and ethylene glycol – it’s harder to recycle.
-
Don’t
ever dispose of antifreeze in a storm drain, septic tank, or dry
well.
-
Don’t
ever pour antifreeze on the ground.
-
Don’t
discharge to a city sewer system without prior approval.
