NASHVILLE, Tenn. (AP) - Tennessee State Parks have expanded recycling with interior recycling bins added at all 56 state parks.

The Tennessee Department of Environment and Conservation said in a news release that more than 400 exterior recycling receptacles were placed in August.

The release says the state has received all of the new Recycle Away Triple Recycling Station receptacles. The bins are made with 97 percent pure recycled plastic from milk jugs. Each bin uses about 1,000 milk jugs.

The bins are designed to last decades but can also be recycled when they are no longer usable.

They're part of a state parks sustainability initiative called Go Green With Us.
