Juice cartons are primarily made of paper, but they also contain layers of plastic and, in some cases, aluminium. This combination of materials makes juice cartons a hybrid of paper and plastic. The layers of paper, plastic, and aluminium in cartons can be difficult to separate, traditionally making them challenging to recycle. However, advancements in recycling technology have made it easier to recycle juice cartons, and many recycling centres now accept them.

Juice cartons are primarily made of paper
The paper carton was invented in the early 20th century and is designed to keep the product inside fresh by blocking out light and air that may cause spoilage. The colourful labelling on the outside is printed on the thin plastic layer. When recycled, this layer is removed to leave behind valuable paper fibres that can be used to make new paper products.
Recycling cartons can be challenging due to the layers of different materials, but it is becoming easier. The Carton Council was formed in 2009 to increase recycling capabilities for aseptic and gable-top cartons in the United States. Some countries, like Mexico and Brazil, have found ways to recycle cartons, such as turning them into pellets for building materials.
In the recycling process, the paper fibre is separated from the other materials and can be transformed into new products like tissues, office paper, and building materials. The plastic and aluminium materials are also collected and repurposed separately. For example, the plastic can be used for shipping crates and building materials, while the aluminium can be used to generate energy.

They also contain thin layers of plastic and aluminium
Juice cartons are primarily made of paper. However, they also contain thin layers of plastic and, in some cases, aluminium. Gable-top or refrigerated cartons, for example, typically have an 80% paper and 20% plastic composition. This combination helps to keep the liquid inside while blocking out light and air that could cause spoilage.
The plastic layer in juice cartons is typically made of polyethylene, a type of plastic known for its flexibility and durability. This thin layer of plastic also serves as the canvas for the colourful labelling often seen on juice cartons. While it is recyclable, the plastic layer can be challenging to separate from the paper during the recycling process. This challenge has traditionally resulted in cartons being sent to landfills. However, advancements in recycling technology and the emergence of specialised facilities, such as the Carton Council, are making it easier to recycle these hybrid packages.
The aluminium layer is found in aseptic or shelf-stable cartons. These cartons are designed to be stored at room temperature and have an average composition of 74% paper, 22% plastic, and 4% aluminium. The aluminium layer provides additional protection against oxygen and light, enhancing the shelf life of the packaged product.
Recycling juice cartons can be a complex process due to the combination of materials. The layers of paper, plastic, and aluminium must be separated, and each material has different recycling requirements. Some recycling centres may not have the necessary technology to separate and process these materials effectively. However, recycled juice cartons can be transformed into valuable new products. The paper fibres can be used for tissues, office paper, or building materials, while the plastic can be repurposed for shipping crates or combined with aluminium to create energy for industrial facilities.

Cartons are difficult to recycle due to their layers of material
Cartons are primarily made of paper, but they also have thin layers of plastic and, in some cases, aluminium. Gable-top (refrigerated) cartons contain additional layers of plastic, while aseptic (shelf-stable) cartons contain additional layers of plastic and aluminium.
These layers of different materials can be difficult to separate, making cartons challenging to recycle. The process of separating the layers to recycle them can be complex and time-consuming. In the past, cartons were often not accepted by recycling plants and ended up in landfills. However, recycling technology has improved, and many recycling centres in the United States and other countries are now able to accept and recycle cartons.
The process of recycling cartons typically begins at a materials recovery facility, where cartons are separated from other waste and types of recyclables. From there, the cartons are shipped to paper mills, where they are mixed with water in a hydra-pulper to separate the paper fibres from the plastic and aluminium. The paper fibres can then be used to make new paper products, such as tissues, office paper, and building materials.
The plastic and aluminium materials collected during the hydra-pulping process can also be recycled separately. The plastic can be used for shipping crates and building materials, while the aluminium can be combined with the plastic to create a poly/al mix used for energy generation. However, the poly/al mix has limited secondary use markets.
While recycling cartons is becoming easier, it is important to check with local recycling guidelines, as different areas may have specific requirements or limitations. Some places may require cartons to be separated from other recyclables, while others may accept them as part of a single-stream recycling program. Additionally, some recycling programs may have specific preparation requirements, such as rinsing or flattening cartons before placing them in the recycling bin.

Carton recycling is improving, with 62% of US households now able to do so
Cartons are primarily made of paper, with a thin layer of polyethylene or plastic. Gable-top or refrigerated cartons, often used for milk, contain additional layers of plastic, while aseptic or shelf-stable cartons have layers of plastic and aluminium. The colourful labelling on the outside is printed on the thin plastic layer.
Due to the multiple layers of materials, cartons have traditionally been difficult to recycle. However, recycling cartons is becoming easier. The Carton Council, formed in 2009, has played a crucial role in increasing recycling capabilities for aseptic and gable-top cartons in the United States. The council's efforts have resulted in a significant increase in carton recycling access, with 62% of US households now able to recycle cartons through curbside and drop-off programs. This marks a remarkable improvement from 2009, when only 18% of US households had access to carton recycling.
The Carton Council has attributed this progress to several factors, including an expanded market for recycled carton materials, technological advancements, and collaborations with organisations promoting recycling. For instance, robotic sorters have been introduced to remove cartons from the recycling stream efficiently. Additionally, the council has launched educational campaigns to raise awareness about carton recycling among communities and companies.
Despite the progress, challenges remain in some cities with advanced recycling programs, such as Austin, where cartons are still not accepted for recycling. Furthermore, while recycling plants can strip the fibre from cartons for recycling, they may not always recycle the plastic or aluminium components. Nevertheless, companies like ReWall Co. are finding innovative ways to recycle cartons, such as shredding and smashing them into boards for roofing and siding.

Plastic milk cartons can be melted down and turned into new products
Cartons are made from a combination of paper, plastic, and sometimes aluminum. Gable-top or refrigerated cartons are primarily made of paper with additional layers of plastic. On the other hand, aseptic or shelf-stable cartons contain extra layers of plastic and aluminum. The colorful labeling on the carton is printed on the thin plastic layer.
Plastic milk cartons, along with other types of cartons, can be recycled and turned into new products. However, the layers of different materials in cartons can be challenging to separate, which has traditionally made them difficult to recycle. The Carton Council was formed in 2009 to address this issue and increase recycling capabilities for aseptic and gable-top cartons in the United States.
The recycling process for plastic milk cartons involves sending the cartons to a Materials Recovery Facility (MRF) after they have been collected from consumers. At the MRF, the cartons are sorted, baled, and then sent to paper mills and recycling plants. The whole cartons are shredded and smashed into boards that can be used for roofing, siding, and other building projects.
At the paper mills, the cartons are put into a hydra-pulper, which separates the paper fibers from the plastic and aluminum. The paper pulp is then used to create new paper products such as tissues, office paper, and building materials. The plastic and aluminum materials collected during the hydra-pulping process are used for various purposes, such as shipping crates and building materials. In some cases, the plastic and aluminum are combined to create a poly/al mix, which can be used to generate energy for facilities.
