Most Little League Baseball groups have taken steps to ban metal baseball bats in games because they can cause extreme head injuries to players. And like most antiquated sporting equipment, these bats may be collecting dust in the basement or in the storage spaces of athletic groups. The good news? They are easily recyclable, since the majority of a metal bat is aluminum. To recycle them, all you have to do is remove the grip, which is likely to be plastic. Then toss the bat into your curbside recycling bin.
