Fact: Recycling one aluminum can saves enough energy to run a TV for three hours. So, yes, it pays off. Here’s how to do it right wherever you live.

Collect newspapers in a paper grocery bag or in tied bundles, depending on your community’s guidelines, and set them out on pickup day. (It takes up to 75,000 trees to produce one Sunday edition of the New York Times.)

Don’t recycle wet cardboard. It can clog sorting machines. Throw it away to keep it from contaminating the rest of the load.

Don’t recycle bottle tops; they’re not made from the same plastic as recyclable bottles. But if you forget, don’t sweat it. They’ll be sorted down the line. (The energy saved by recycling one plastic bottle can power a computer for 25 minutes.)

Rinse cans, but crushing isn’t necessary. The aluminum can is the most recycled item in the United States, as well as the most valuable. It can be recycled again and again, and so efficiently that a can is regenerated and back on the shelf in as little as 60 days.

Don’t fret if you can’t get the lime out of the beer bottle or the last of the peanut butter from the jar. The recycler’s machinery will zap all contaminants. But do empty and rinse glass jars and containers.
