Milk cartons with plastic spouts can be recycled, but the process depends on your local facilities. Milk cartons are primarily made of paperboard, with a thin layer of plastic and sometimes aluminium to keep the liquid inside fresh. This mix of materials makes milk cartons challenging to recycle. While the paperboard is recyclable, the plastic lining must be separated, which some facilities can do and others cannot. If your local facilities can recycle milk cartons, you can recycle the entire carton without cutting out the plastic spout. However, it's important to empty and rinse the carton before recycling and to keep it unflattened to make it easier to sort.

What You'll Learn
Milk cartons are recyclable
While milk cartons are designed to be recyclable, it's important to check that your local facilities are equipped to process them. In the past, it was difficult to recycle cartons due to their mixed composition. However, advancements in recycling technology have made it possible for more communities to recycle milk cartons.
Currently, about 62% of communities in the United States can recycle milk cartons. If your community accepts milk cartons for recycling, simply empty and rinse the carton before placing it in the recycling bin. It's important to keep the carton unflattened and to secure any caps or straws to prevent them from becoming litter.
After collection, milk cartons are sent to Materials Recovery Facilities (MRFs) where they are sorted, baled, and sent to recycling plants or paper mills. At paper mills, the paper is separated from the plastic and aluminium through a process called hydropulping. The paper pulp is then used to create new paper products, while the plastic and aluminium can be made into building materials like construction board.
If your local facilities do not accept milk cartons for recycling, you can consider reusing them for various projects and crafts. For example, milk cartons can be cut, painted, and transformed into planters or storage containers for dry goods.

Plastic spouts don't need to be cut out
Milk cartons are recyclable, but the ability to recycle them depends on your local facilities. The majority of milk cartons are primarily made of paper, with a thin layer of plastic or, sometimes, aluminium. This composition means they can be broken down and turned into new paper products. However, not every recycling program accepts them.
If your local facilities do accept them, you do not need to cut out the plastic spout before recycling. Judie Miller, a recycling information supervisor, confirms this. Gable-top cartons (the peaked ones that milk and orange juice come in) are fine to recycle. Just don't flatten them because that makes them harder to sort. Also, empty and rinse them before recycling.
After you recycle your cartons, they are sent to a Materials Recovery Facility (MRF). The cartons are sorted, baled, and sent to paper mills and recycling plants. At paper mills, cartons are put in a hydro pulper, where the paper is separated from the plastic and aluminium. The pulp is sent directly to the mill's paper machine or dried into sheets that are turned into paperboard, tissue, and cardboard.
Cartons can also be packed together and sent to a paper mill, where they are put into a giant blender (called a Hydrapulper). That enables the paper to be separated from the plastic and aluminium. The resulting paper pulp is used to make paper towels, tissue, and printing paper. The plastic and aluminium can be made into ceiling tiles, wallboard, and other products.

Rinse and dry cartons before recycling
Milk cartons with plastic spouts can be recycled, but it's important to prepare them properly before sending them off to be processed. Rinsing and drying your milk cartons is an essential step in this process, ensuring that your cartons are free of residue and ready for their next journey. Here's a step-by-step guide to rinsing and drying your milk cartons:
Empty and Initial Rinse:
Start by emptying any remaining liquid from your milk carton. Give it an initial quick rinse to remove most of the residue. You don't need to use soap or scrub vigorously—a simple swish of water will do. This step ensures that your carton is mostly clean and helps keep the paper dry.
Drying:
After rinsing, let the carton dry. You can place it upside down in your dish rack or on a towel. It's important to ensure that the carton is dry before placing it in the recycling bin, as wet containers can cause issues during the recycling process.
Final Check:
Before placing your milk carton in the recycling bin, perform a final check to ensure it is completely dry and free of any sticky residue. If you notice any stubborn residue, you may need to give it an additional quick rinse or use a small amount of dish soap and a sponge to remove it. Remember, the goal is to have a clean, dry carton that won't cause contamination during the recycling process.
Recycling the Carton:
Once your milk carton is thoroughly rinsed and dried, you can recycle it. Check with your local guidelines to confirm if your community accepts milk cartons for recycling. If they do, you can place the carton in your recycling bin or take it to a designated drop-off location. If your local program doesn't accept milk cartons, you may need to explore other options, such as finding a facility that can handle the specific materials of the carton.
Remember, while rinsing and drying are essential steps, you don't need to make your milk cartons spotless or waste excessive water in the process. The goal is to remove most of the residue and create a clean, dry surface for successful recycling.

Check local recycling guidelines
Milk cartons with plastic spouts are recyclable, but the ability to recycle them depends on your local facilities. While milk cartons are designed to be recyclable, not all local facilities are equipped to process them.
To check if your local recycling program accepts milk cartons with plastic spouts, you can start by visiting your city or county's recycling webpage or giving their hotline a call. They can provide specific information on carton recycling in your area, including any drop-off locations for recycling cartons, which may differ from where you recycle plastic containers.
It is worth noting that milk cartons with plastic spouts are typically made of multiple materials, including paper, plastic, and sometimes aluminum. This mix of materials has historically posed a challenge for recycling, as not all facilities can separate and process these different components. However, advancements in recycling technology have made it possible for a growing number of communities to recycle milk cartons effectively.
If you find that your local community does not currently accept milk cartons with plastic spouts for recycling, you can take the initiative to educate them about the importance of starting a recycling program for these cartons. By advocating for carton recycling in your area, you can help increase the number of communities that are able to properly recycle these materials and positively impact the environment.
