2. Pay attention to all of those complicated symbols.
All plastic containers are labeled with a resin identification code (RIC) that tells you which grade of plastic you’re dealing with, and how well it can be recycled.
According to environmental research blog Greenopedia, plastics labeled 1 and 2 can be recycled at almost every recycling center, but numbers 3, 6 and 7 usually cannot be recycled and can go directly in the trash. Some recycling centers can process plastics labeled 4 and 5, so call your local center to see if they accept those containers.
