How to Recycle Plastic Bags

Of course, the goal is to not using plastic bags in the first place. However nobody is perfect and even the most eco-friendly minded can get caught in the situation of not having a reusable handy. The confusion over what we can and cannot recycle continues to confound consumers. Plastics are especially troublesome, as different types of plastic require different processing to be reformulated and re-used as raw material. Some municipalities accept all types of plastic for recycling, while others only accept jugs, containers and bottles with certain numbers stamped on their bottoms.

Plastic grocery bags come in two types: Type 2: High-density polyethylene film - HDPE. Type 4: Low density or linear-low density polyethylene film - LDPE/LLDPE

Recycling by the Numbers

The symbol code we’re familiar with—a single digit ranging from 1 to 7 and surrounded by a triangle of arrows—was designed by The Society of the Plastics Industry (SPI) in 1988 to allow consumers and recyclers to differentiate types of plastics while providing a uniform coding system for manufacturers.

The numbers, which 39 U.S. states now require to be molded or imprinted on all eight-ounce to five-gallon containers that can accept the half-inch minimum-size symbol, identify the type of plastic. According to the American Plastics Council, an industry trade group, the symbols also help recyclers do their jobs more effectively.

Easy Plastics to Recycle

The easiest and most common plastics to recycle are made of polyethylene terephthalate (PETE) and are assigned the number 1. Examples include soda and water bottles, medicine containers, and many other common consumer product containers. Once it has been processed by a recycling facility, PETE can become fiberfill for winter coats, sleeping bags and life jackets. It can also be used to make bean bags, rope, car bumpers, tennis ball felt, combs, cassette tapes, sails for boats, furniture and, of course, other plastic bottles.

Number 2 is reserved for high-density polyethylene plastics. These include heavier containers that hold laundry detergents and bleaches as well as milk, shampoo and motor oil. Plastic labeled with the number 2 is often recycled into toys, piping, plastic lumber and rope. Like plastic designated number 1, it is widely accepted at recycling centers.

Plastics Less Commonly Recycled

Polyvinyl chloride, commonly used in plastic pipes, shower curtains, medical tubing, vinyl dashboards, and even some baby bottle nipples, gets number 3. Like numbers 4 (wrapping films, grocery and sandwich bags, and other containers made of low-density polyethylene) and 5 (polypropylene containers used in Tupperware, among other products), few municipal recycling centers will accept it due to its very low rate of recyclability.

Another Useful Plastic to Recycle

Number 6 goes on polystyrene (Styrofoam) items such as coffee cups, disposable cutlery, meat trays, packing “peanuts” and insulation. It is widely accepted because it can be reprocessed into many items, including cassette tapes and rigid foam insulation.

Hardest Plastics to Recycle

Last, but far from least, are items crafted from various combinations of the aforementioned plastics or from unique plastic formulations not commonly used. Usually imprinted with a number 7 or nothing at all, these plastics are the most difficult to recycle and, as such, are seldom collected or recycled. More ambitious consumers can feel free to return such items to the product manufacturers to avoid contributing to the local waste stream, and instead put the burden on the makers to recycle or dispose of the items properly.

Put it into Action

- 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.

- 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.

- 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.
