Plastic grocery bags Type 2 (high-density polyethylene film - HDPE) and
Type 4 (low density or linear-low density polyethylene film - LDPE/LLDPE)
can be recycled at your local supermarket and other locations. Once the
bags are recycled, they are made into lumber, trashcan liners or plastic
bags.

Instructions
STEP 1: Find out if your local curbside recycling program will accept plastic
grocery bags. STEP 2: Drop off plastic grocery bags Type 2 and Type 4 at
your local grocery store, if you cannot recycle them through your curbside
program. Most grocery stores will accept plastic bags and have recycling
bins inside the store. STEP 3: Exclude any plastic bags that are dark in
color or bags that have handles or drawstrings. Plastic food packaging and
plastic food wrap (Saran wrap) are also non-recyclable. STEP 4: Clean and
dry bags thoroughly before recycling, making sure they are empty of any
debris. This is important, since foreign objects will contaminate the plastic
as it is being recycled. STEP 5: Check with your county department of
public works to find out about local curbside recycling programs and
community drop-off centers, or look under "Recycling" in the Yellow Pages

Tips & Warnings
The type of plastic the bag is made from should be printed somewhere on
the bag.
Often plastic bags that are used for bread and other products are made
from Type 2 and Type 4 plastic, but are not marked. They can usually be
recycled with plastic grocery store bags unless they have the numeral 7
on them, which means they are definitely not recyclable.
