Seattle residents are being asked to take part in a friendly recycling competition June 22-26 to help their neighborhood be dubbed the “Greenest Seattle Neighborhood.”

Call2Recycle, North America’s first and largest consumer battery stewardship and recycling program, is partnering with The Seattle Public Library to put battery collection boxes at six different branches, including the Capitol Hill branch at 425 Harvard Ave. E. The neighborhood whose box weighs the most will be crowned the greenest in Seattle. Boxes will be weighed at Call2Recycle’s collection event June 28 at Westlake Park with the help of local celebrity John Curley.

“We want to know which Seattle neighborhood can gather the most batteries,” says Jennifer Childress, director of marketing and communications for Call2Recycle. “After you drop off batteries, make sure to tweet us at @Call2Recycle so we can say thank you.”

Drop batteries and cell phones to the Capitol Hill library June 22-26.

Call2Recycle will accept all types of household batteries (weighing up to 11 pounds each), including both single-use batteries and rechargeable batteries commonly found in laptops and digital cameras. Old cell phones can also be dropped off at the library for recycling.

“The Seattle Public Library is happy to be involved,” says Chance Hunt, assistant director of community partnerships and government relations. “We’re excited to see how many batteries Seattleites can donate for recycling, and to find out which neighborhood truly is the greenest.”
