Milk cartons with plastic spouts are recyclable, but whether or not they can be recycled 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 is what makes milk cartons a unique challenge when it comes to recycling. While the paperboard is recyclable, the plastic lining must be separated, which some facilities can do, but others might not.

What You'll Learn
Milk cartons are recyclable but local facilities may vary
Milk cartons are technically recyclable, but whether or not they can be recycled in your local area depends on the facilities available to you.
Milk cartons are typically made up of layers of plastic, paper, and sometimes aluminum. Gable-top cartons, found in the refrigerated section, are generally made of 80% paper and 20% plastic, with a plastic layer on the outside and inside. Aseptic cartons, also known as "shelf-stable" cartons, are made of paper, plastic, and aluminum liners and do not need to be kept cold.
The recyclability of milk cartons depends on the ability of local facilities to separate and process these different materials. While the paperboard is recyclable, the plastic lining must be separated, which some facilities may not be equipped to do. Approximately 62% of communities in the United States are capable of recycling milk cartons.
It is important to check with your local guidelines to determine if milk cartons are accepted for recycling in your area. If your community does not accept milk cartons for recycling, you can advocate for the implementation of carton recycling programs or find alternative ways to reuse or repurpose them.
When recycling milk cartons, it is generally recommended to empty and rinse them without flattening, and to tuck in any straws or screw on the cap to prevent them from becoming litter.

Plastic spouts do not need to be cut out
Milk cartons with plastic spouts can be recycled, and you do not need to cut out the plastic spout before recycling. However, it is important to check your local guidelines as recycling programs and facilities differ across regions.
In the United States, about 62% of communities are capable of recycling milk cartons. This is a significant improvement due to advancements in recycling technology. However, it is essential to note that not all recycling programs accept milk cartons, so it is advisable to check with your local facilities to ensure they can process them.
The recyclability of milk cartons depends on their composition. Milk cartons are typically made of paperboard with a thin layer of plastic and, in some cases, aluminum. The paperboard provides structure and strength, while the plastic and aluminum layers create a liquid-tight seal, preserving the liquid inside.
While the paperboard is recyclable, the challenge lies in separating the different materials, especially in cartons with plastic spouts. However, specific facilities can handle these mixed materials. At recycling plants, the entire carton is often turned into building materials like construction boards, and the separated materials are used for other products.
To recycle milk cartons with plastic spouts, ensure they are empty and rinse them before recycling. It is recommended to keep the cartons unflattened as it makes them easier to sort. If the carton has a cap, screw it back on to prevent it from becoming litter during the recycling process.

Gable-top cartons are recyclable
While gable-top cartons are recyclable, the ability to recycle them depends on your local facilities. Before recycling, it is important to empty and rinse the carton and screw the cap back on to prevent it from becoming litter. It is also recommended to not flatten the carton as this makes it harder to sort.
The recyclability of gable-top cartons has improved in recent years due to advancements in recycling technology. Today, about 62% of communities in the U.S. are capable of recycling milk cartons. This is a significant improvement from previous years when various types of cartons were difficult to recycle because of their mix of materials. Now, the whole carton can be turned into building materials such as construction board.
Gable-top cartons can also be reused instead of being recycled. For example, they can be washed and used for storing dry items such as sugar, rice, or sprinkles. They can also be cut and used as planters.

Aseptic cartons are also recyclable
Milk cartons with plastic spouts are recyclable, but the process and availability of recycling methods depend 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 is what makes milk cartons a unique challenge when it comes to recycling.
Aseptic cartons are recycled by being sent to a Materials Recovery Facility (MRF). Here, the cartons are sorted, baled, and sent to paper mills and recycling plants. At paper mills, the cartons are put in a Hydrapulper, which separates the paper from the plastic and aluminium. The resulting paper pulp is then used to make new paper products such as paper towels, tissue, and printing paper. The plastic and aluminium are used to create other products such as ceiling tiles and wallboard.
It is important to note that before recycling aseptic cartons, they should be emptied, not flattened, and any straws or caps should be tucked or screwed back on, respectively, to prevent them from becoming litter. Additionally, they should be rinsed before recycling.

Cartons are made from a mix of materials
Milk cartons are made from a mix of materials, typically paperboard, and a thin layer of plastic and/or aluminum. This multi-layered composition is what makes milk cartons liquid-tight and able to keep their contents fresh. The paperboard gives the carton its structure and strength, while the plastic and aluminum act as a moisture barrier.
The two main types of milk cartons are gable top and aseptic. Gable-top cartons are generally found in the refrigerated section of supermarkets and are made of paper and a plastic liner. Aseptic cartons, also known as shelf-stable cartons, are made of paper, plastic, and sometimes aluminum liners. They are designed to sit on a shelf and do not need to be refrigerated.
The mix of materials in milk cartons has historically posed a challenge to recyclers. The biggest challenge is separating the different components. However, advancements in recycling technology have made it possible for many communities to now recycle milk cartons.
At recycling plants, the whole carton is typically turned into building materials like construction board, rather than separating the paper and plastic components. In some cases, the paper is separated from the plastic and aluminum through a process called hydrapulping. The resulting paper pulp is used to make new paper products, while the plastic and aluminum are made into other products like ceiling tiles and wallboard.
It's important to note that the ability to recycle milk cartons depends on the local facilities and their capabilities. While most types of milk cartons are designed to be recyclable, not every recycling program accepts them. Before recycling, it's important to check with your local guidelines and prepare the cartons accordingly, such as by emptying and rinsing them and keeping the caps on to prevent them from becoming litter.
