If you have kids, you probably have LEGO® bricks. A lot of them. But what do you do with them when your kids are done with them? While you can’t recycle them, you can donate them for REUSE.
Here are two options:
1) Donate them to friends, schools, or your local thrift store. (Call first to make sure they’ll accept them.)
2) Send them back to LEGO for free. The LEGO® Replay program is a simple-to-use platform that allows you to pass forward your much-loved LEGO bricks and share the power of play with kids in need. This program has already collected over 720,000 pounds of bricks to redistribute. Just follow the instructions on their website to print a free shipping label, box up your LEGO bricks, and send them in.
