Plastic recycling is a confusing process, and with good reason: there are so many types of plastic, and some types are not accepted by community recycling programs. The U.S. Environmental Protection Agency estimates that over 30% of all plastic waste is recycled, but this figure could be much higher. Plastic recycling helps to reduce the amount of waste sent to landfills and conserve natural resources, so it is important to know how to recycle plastic properly.

What You'll Learn
Plastic bag recycling
Plastic bags are among the most common sources of marine debris, often mistaken as food by birds and fish. They do not biodegrade, meaning they will take hundreds of years to decompose in a landfill. Recycling plastic bags is therefore essential to reducing waste and helping the environment.
Firstly, it is important to ensure that any plastic bags you wish to recycle are clean and dry. This is because clean plastics can be recycled effectively without contaminating other materials. A light wipe with a dry cloth to remove any residue should suffice. You should also tear off any sticky labels where possible.
Secondly, you should check that the plastic bags have a #2 or #4 plastic symbol on them. If they do not, you cannot be sure what plastic resin the bag is made from, and so you should consider reusing it before eventually throwing it away. Most retail and grocery plastic bags are made from #2 (High-Density Polyethylene – HDPE) or #4 (Low-Density Polyethylene – LDPE) plastic. LDPE and HDPE resins are created using fossil fuels, so recycling plastic bags helps to reduce the amount of fossil fuels needed for the manufacturing of virgin resin.
Thirdly, you should gather your plastic bags in bulk for more efficient drop-off. Bringing large amounts of plastic bags supports better recycling practices.
Finally, you should take your plastic bags to a recycling collection point. Plastic bags cannot be recycled in most curbside recycling bins as they are soft plastics that can get caught in machinery at large recycling facilities. Instead, you should take them to a participating retail store with a store drop-off program. Many large retailers, including Target and Walmart, collect plastic bags from consumers. These retailers back-haul the plastic film to multiple businesses that recycle it into new products.

Plastic film recycling
Plastic film is one of the fastest-growing packaging formats. It is also one of the most common sources of marine debris, with plastic bags taking hundreds of years to decompose in a landfill. However, recycling a ton of plastic bags saves 11 barrels of oil.
Recycling plastic film saves anywhere from 8 to 23% of greenhouse gas emissions when compared to manufacturing new plastic. Recycled plastic films become products like lumber, decking, stormwater management systems, construction materials, and new flexible plastic films.
To recycle plastic film, it is important to ensure that the plastic is clean and free of food. Sticky labels should be torn off where possible. Plastic films can be recycled at retail and grocery stores, with some retailers offering bag recycling collections in their stores. National grocery retailers such as Kroger, Safeway, Target, and Walmart offer bag recycling collections in their stores, with bins usually located near the front entrance.
Before bringing plastic film to a store, it is important to verify that the store accepts the specific type of plastic film for recycling. Plastic films that can stretch and have an equilateral triangle with resin codes 2 or 4 on them can be recycled.

Plastic bottle recycling
Plastic bottles are among the most common sources of marine debris and can take hundreds of years to decompose in a landfill. Recycling plastic bottles is an easy way to protect the environment.
Before recycling, it is important to clean, dry, and remove any labels or packaging from your plastic bottles. You should also rinse the bottle and remove the cap. The bottle doesn't need to be perfectly clean, but no residue should be inside. Most recycling programs ask that you rinse your bottles before recycling. You should also check with your local program whether to keep the caps on the bottles, as some programs want the cap on to prevent loose caps from falling out during transportation, while others want them off to ensure the bottle is empty and because their machinery may be damaged when trying to crush a capped bottle. You can also crush your bottles to save space, but be aware that some plastics, such as yogurt containers or butter tubs, will crack and be difficult to bale.
Most bottles are made from #1 plastic (PET) or #2 plastic (HDPE), which are accepted by most curbside recycling programs and can be recycled by any recycling company. You can check the number etched into the bottom of the bottle to see what kind of plastic it is. If your bottle has a number other than 1 or 2, you should double-check that your recycling center can take it. When recycling, toss your clean bottles into a designated recycling bin or container if they are stamped with the number 1 or 2. You can sign up for a weekly recycling curbside program, or drop off your recyclables at a recycling center near you.
If you have questions about plastic bottle recycling in your area, you can contact your county recycling coordinator or visit their website.

Plastic container recycling
Plastic containers are hard to recycle, and they cannot be put in your curbside recycling bin. However, there are still ways to recycle or reuse them.
Firstly, check with your local recycling program to see if they accept plastic containers. Some local programs do, and they will be able to tell you where to take them. You can also check with your local government to see if there are any drop-off locations for plastic containers.
If your plastic containers are in good condition, you could donate them to thrift stores, local charities, child care centers, senior centers, or schools. You could also give them away on websites such as Freecycle or online material exchanges in your area.
If you want to recycle plastic bags, make sure they have a #2 or #4 plastic symbol on them. If they don't, reuse them before throwing them away. Plastic bags can be recycled at most national grocery retailers, such as Kroger, Safeway, Target, and Walmart, and many smaller retailers.
When it comes to other plastic containers, it depends on the type of plastic they are made of and whether your local program accepts that type. Items with food debris cannot be recycled. Plastic utensils and compostable plastics also cannot be recycled.

Compostable plastic recycling
Compostable plastic is designed to biodegrade into soil-conditioning material, also known as compost. It is not intended to be recycled and can contaminate and disrupt the recycling process if mixed with non-compostable plastics. Therefore, it is important to separate compostable plastics from non-compostable plastics.
Compostable plastics can be divided into two categories: home compostable and industrial compostable. Home compostable plastics can be placed in a home composting bin or heap, but they require specific conditions, including high heat sustained over a long period. Industrial compostable plastics are designed to break down in commercial or industrial composting facilities with the right mixture of heat, microbes, and time. These facilities are typically run by cities or counties and may be available in some areas.
If your community does not have a composting program that accepts compostable plastic, you can contact your local government or recycling company to inquire about drop-off locations for compostable plastic items. It is important to check the labels on compostable plastic items, as they should specify whether they are home or industrially compostable.
When it comes to plastic bags, it is important to note that they are a significant source of contamination in recycling programs. Plastic bags are often not accepted in curbside recycling and can cause issues for machinery at recycling centers. Retailers often offer bag recycling collections in their stores, providing dedicated bins for plastic bag recycling. Additionally, some communities have implemented bag bans or taxes to reduce plastic bag waste and encourage the use of reusable bags.
To recycle large amounts of plastic, it is essential to separate the plastics by type and check with your local recycling program to determine which types of plastic they accept. Some plastics, such as styrofoam, may not be accepted by curbside recycling programs. You can also look for products made from recycled plastic materials to support the recycling process and reduce waste.
