Why You Shouldn’t Crush an Aluminum Can Before Recycling It

Crushing aluminum cans is more than just fun—it means the can will take up less space, right? Not so fast—it turns out crushing aluminum cans is actually worse for the environment because it can muck up the sorting process.

“Crushed aluminum cans may fall through the spaces of the sorting equipment and can either be lost entirely or improperly sorted,” Matt Meenan, the senior director of public affairs at the Aluminum Association, recently told Lifehacker. That means crushed cans may end up being sorted as paper or other products, says Meenan, which ends up contaminating the entire batch of recyclables. Keeping cans as intact as possible is best for recycling. Plastic bottles, on the other hand, are best recycled crushed—and with the caps on. Here’s why.

There is an exception to Meenan’s advice, however: If your city or town uses a multi-stream or dual-stream recycling method, you can crush away. Multi-stream means that you separate your recyclables, and since all the cans go together, they can’t contaminate other products.

So, keep the can crushing contests to a minimum going forward, for the sake of the environment. And if you’re confused about what’s recyclable, check out the 15 things you should never put in the recycle bin.

Will Cicadas Destroy Your Garden? 10 Things You Need to Know

So it’s understandable that questions like, “Will cicadas eat my plants?” immediately spring to mind. But cicadas are also pretty fascinating and play important roles in the ecosystem. “Cicadas inspire wonder in our world!” says Jennifer Hopwood, senior pollinator conservation specialist at the Xerces Society for Invertebrate Conservation. “They spend most of their life underground next to the same plant roots. Somehow, these creatures are able to track the years that pass by and time their emergence with other periodical cicadas in the region to overwhelm predators. They are amazing little critters.” Here’s a rundown of what to know about cicadas, good and bad, including whether or not they eat plants and how to protect your trees during an emergence.
