According to Earth911, household batteries contain toxic heavy metals, and nearly 180,000 tons of batteries are thrown away each year. Help reduce that number this holiday season; don’t ask for and avoid purchasing gifts that require batteries. Alternatively, a set of rechargeable batteries with a charger would make a great gift! You can even purchase solar-powered battery chargers. Rechargeable batteries can be recycled at Best Buy, Home Depot, Lowe's, and Mom's Market. Household batteries must be disposed of either at a Delaware County Household Hazardous Waste collection event or in the trash.
