Most businesses use some type of battery. Most batteries meet the definition of dangerous waste, but are included in the definition of universal waste. If properly managed, most businesses can dispose of batteries as universal waste or under the lead-acid battery exclusion rather than the Dangerous Waste Regulations (WAC 173-303-520).
It’s important to properly store batteries as they can:
Start a fire.
Leak chemicals, such as mercury, lead, cadmium, and sulfuric acid.
Not a business?
If you are a household or individual, do not put batteries in curbside recycling bins or trash. Find recycling drop-off locations through 1-800-RECYCLE or Call2Recycle.
