How to Read a Recycling Symbol (And What Actually Gets Recycled)
Those chasing arrows on the bottom of a container aren't a promise. They're a code — and most people have never learned to read it.
The symbol doesn't mean what you think
The little triangle of arrows stamped into plastic isn't a recycling guarantee. It's called a resin identification code, and it was created by the plastics industry in 1988 to tell sorting facilities what type of plastic they're looking at — not whether anyone will actually recycle it.
That's a big difference. Some of these seven codes are recycled at real scale nationwide. Others almost never make it past a landfill, no matter which bin you put them in.
The 7 codes, decoded
The rule of thumb: #1 and #2 are your safe bets almost everywhere in the U.S. Everything else depends heavily on your specific city's program — recycling rules are hyperlocal, and "your neighbor's town" is not "your town."
What actually gets recycled, by the numbers
Here's where it gets interesting: even materials that can be recycled don't all get recycled at the same rate. This chart shows real U.S. recovery rates by material — the gap between "recyclable" and "actually recycled" is bigger than most people expect.

Three free habits that actually move the needle
1. Check the number, not the arrows. A triangle doesn't mean recyclable. A #1 or #2 usually does.
2. Rinse it out. A greasy peanut butter jar can contaminate an entire batch at the sorting facility, sending recyclable material to the landfill along with it.
3. Look up your actual city's list. Every municipality's program is different. Five minutes on your city's waste management website will tell you more than any general rule ever could.
Good enough, not perfect
You don't need to memorize all seven codes. Just remember: #1 and #2 are almost always safe, everything else is a "check your city" situation, and rinsing your containers matters more than most people realize.
