But here’s the good news – are milk cartons recyclable, and more people are getting access to carton recycling than ever before! In this guide, we’ll break down everything you need to know about milk carton recyclability, how to dispose of them properly, and how small actions can make a significant impact on our environment. Let’s dive in and explore the many ways you can help the planet by recycling your milk cartons!

Understanding Milk Cartons

Milk cartons come in different types and materials, and understanding the composition of each can help us better understand how to recycle them.

• What Makes Up a Milk/Juice Carton?
  Milk cartons are typically made from layers of paper, plastic, and sometimes aluminum. These layers are combined to create durable packaging that protects the product inside. There are two primary types of milk cartons:
  
  • Gable-Top Cartons: These are the traditional cartons you will often find in the refrigerated section of your grocery store. They are made of paperboard and are coated with a thin layer of plastic on the inside to make them waterproof. Gable-top cartons are commonly used for refrigerated beverages like milk, juice, and cream.
    
  • Aseptic Cartons: These are also known by the brand name Tetra Pak. These cartons are typically shelf-stable and contain multiple layers, including paper, plastic, and aluminum. They are used for products that don’t require refrigeration, such as plant-based milks, juices, soups, and broths.
    
• Types of Milk Cartons
  
  • Gable-Top Cartons (Refrigerated Cartons): These cartons are made primarily of paper and plastic, and they are used for refrigerated products like milk and juice.
    
  • Aseptic Cartons (Shelf-Stable Cartons): These cartons are made of paper, plastic, and aluminum and are used for non-refrigerated products like soups, broths, and plant-based beverages. Both types are recyclable in many areas

Type of Carton	Main Materials	Recyclability	Usage
Gable-Top Cartons	Paper, Plastic	Yes (depends on local program)	Refrigerated products like milk, juice
Aseptic Cartons	Paper, Plastic, Aluminum	Yes (depends on local program)	Shelf-stable products like juice, soups, wine
Fresh Cartons	80% Paper, 20% Plastic	Yes (accepted by most councils)	Fresh refrigerated milk, cream
Long-Life Cartons	74% Paper, 22% Plastic, 4% Aluminum	Yes (depends on local program)	Non-refrigerated products like long-life milk

The Recyclability of Milk Cartons

Recycling milk cartons is a critical practice, but it’s essential to know the requirements for your specific area. The process of recycling these cartons helps to reduce waste in landfills and conserve valuable resources.

• Why Should I Recycle Milk Cartons?
  Recycling milk cartons not only helps reduce landfill waste but also contributes to conserving natural resources. Every year, over one billion beverage cartons are used in the U.S. alone, and recycling these cartons helps prevent them from taking up space in landfills. Cartons are made primarily from paper, which is a renewable resource, and recycling them helps ensure these valuable materials remain in use rather than being wasted.
  Cartons also have a lower environmental impact when compared to other forms of packaging. They are lightweight, which means they require less energy to transport and refrigerate. This ultimately helps reduce the carbon footprint of transporting and storing products in cartons.
  
• Can I Recycle Paper Cartons?
  Yes, you can recycle paper cartons! However, before recycling, make sure that the carton is empty and rinse it to remove any remaining liquid. Don’t flatten the carton, as it is easier for recycling facilities to process them in their original shape. If your carton has a straw, push it inside, and if it has a cap, screw it back on to ensure it doesn’t separate and create waste.
  
• What Are the Different Types of Cartons? Can They All Be Recycled?
  Both gable-top cartons (refrigerated) and aseptic cartons (shelf-stable) are made from layers of paper, plastic, and sometimes aluminium. Both types can be recycled, but it depends on local programs whether your area accepts them. Always check with your local recycling provider to see which types of cartons are accepted in your curbside program.
  
• What Happens to My Cartons After I Recycle Them?
  Once you’ve placed your empty carton in the recycling bin, it is transported to a Materials Recovery Facility (MRF), where it will be sorted and processed. At the recycling facility, the cartons are subjected to a process called hydra pulping, where they are mixed with water to break down the paper fibres. These fibres are then separated from the plastic and aluminum layers. The paper pulp can be used to make new products like tissue, office paper, and even cardboard. The separated plastic and aluminium materials are then repurposed for products like ceiling tiles, and wallboards or even as a source of energy for the recycling facility.
  
• Common Misconceptions About Cartons
  
  • Cartons are not recyclable: False
    Cartons are recyclable! In fact, they are made from high-quality materials like paper, plastic, and aluminum that can be used to make new products. The recycling industry has made significant strides in increasing the availability of carton recycling programs.
    
  • I can’t recycle cartons because they don’t have a symbol on them: False
    While cartons are still working towards placing recycling symbols on their packaging, they are still recyclable. Not every product needs to display a recycling symbol for it to be recyclable. You can check with your local recycling program for specific guidelines.
    
  • Cartons are wax-coated: False
    Modern cartons do not contain wax. Cartons are made of paper with a thin layer of plastic and aluminum to protect the contents from spoilage.
    

How Are Milk Cartons Recyclable?

The process of recycling milk cartons involves separating their components to make new products.

• How Does Carton Recycling Work?
  Cartons are sorted at the recycling facility and then sent to paper mills, where they are mixed with water and subjected to hydra pulping, which separates the paper fibres from the plastic and aluminium layers. The fibres are processed into new paper products, while the plastic and aluminium materials are used for other applications, such as building materials or energy generation.
  
• How Are Recycled Cartons Used?
  Recycled paper fibres from cartons are used to make products like tissue paper, office paper, and cardboard. The plastic and aluminium materials are repurposed for items like ceiling tiles, wallboard, or other building materials.
  
• Challenges in Carton Recycling
  The primary challenge in recycling cartons lies in separating the plastic and aluminum from the paper. However, recycling technology has been improving, and more facilities are becoming equipped to handle cartons more effectively.
  

How to Recycle Milk Cartons

Recycling milk cartons is relatively simple but depends on your local recycling program. Here’s what you need to know:

• Curbside Collection
  Many local recycling programs now accept milk cartons for curbside pickup. Be sure to rinse the cartons before placing them in the recycling bin. Some programs may ask you to leave the cap on or push the straw inside, so be sure to check local guidelines.
  
• Mail-in Recycling
  If your local recycling program does not accept cartons, you may be able to mail them to a recycling facility. Some areas have designated drop-off locations for cartons. The Carton Council also provides instructions for mailing cartons for recycling.

Ways to Reuse Milk Cartons
