Cardboard is practically everywhere; in fact, it’s so common that we often forget just how much we end up throwing away. Recycling cardboard is an important sustainability strategy: it cuts down on waste, helps save trees, and reduces pollution. That’s why we’ve put together this comprehensive guide to cardboard recycling. Whether you’re dealing with cardboard because you’ve just moved or are managing a business, this blog will walk you through some easy steps to recycle cardboard and even share some creative ideas for reusing it.
What is Cardboard?
Put simply, cardboard is a strong paper-based material. It’s made by pressing together layers of cellulose fibers, which usually come from wood or recycled paper. Even though it’s strong, it’s pretty lightweight, making it great for shipping. There are several types of cardboard, each of which has a specific purpose.
Corrugated Cardboard
This is the most common type of cardboard, often used for shipping boxes and moving boxes. It has a wavy fluted layer sandwiched between two flat sheets, which makes it strong and durable. You’ll find it in pizza boxes, moving cartons, and product packaging. As long as it’s clean and dry, corrugated cardboard is highly recyclable and widely accepted.
Paperboard
Paperboard is thinner and lighter than corrugated cardboard. It’s commonly used for cereal boxes, shoe boxes, tissue boxes, and other household packaging. The great thing is that most paperboard can be recycled, as long as it’s clean and free of food residue. Just make sure to remove any plastic liners or inserts before you throw it in the recycling bin.
Wax or Plastic Coated Cardboard
This cardboard is made to resist moisture. It is commonly used for boxes that hold produce, frozen foods, and some beverage cartons. The wax or plastic coating on it makes it hard for recycling facilities to break down the fibers. Because of this, most of the time, this cardboard cannot be recycled and should be thrown away unless there’s a special recycling option in your area.
Contaminated Cardboard
You can’t recycle cardboard that is greasy, covered in food, or soaked in liquid. Dirty cardboard is damaged, making it hard to recycle. If you find clean, dry pieces, you can tear those off and recycle them, but remember to throw away the soiled parts.
Recycling Cardboard
Recycling cardboard helps keep valuable materials out of landfills, and it works best when you handle and prepare the cardboard correctly. A little effort can greatly improve the results of recycling.
Collect & Sort
Make sure to collect cardboard separately from regular trash so it doesn’t get mixed together. Keep your clean, dry cardboard, like those corrugated boxes, away from anything wet and greasy. Sorting your waste early can help avoid rejected loads and make sure the recyclable materials stay in good shape.
Remove or Separate Out Non-Recyclable Items
Before recycling, make sure to completely empty out the boxes. Get rid of plastic wrap, foam inserts, food leftovers, and any other non-paper materials. It’s okay to leave on a little tape or labels, but make sure to remove plastic or styrofoam materials.
Flatten, Prepare, & Store
Flattening cardboard boxes is a smart way to save space and makes it way easier to store and transport them. Just make sure to keep the boxes dry since moisture can weaken the fibers and interfere with the recycling process.
Collection or Drop-off
Research recycling options in your area. If you own a business or live in an apartment building, there may be dumpsters nearby that you can use. If you are dealing with cardboard in your own home, determine whether curbside pickup is available for cardboard recycling. You can also rent a dumpster or hire a waste management company to help you deal with large amounts of cardboard generated by a business, a move, or cleaning out your home.
What Cardboard Items Can Be Recycled?

Cardboard Recycling Tips
A few simple habits can make cardboard recycling more effective and reduce contamination:
- Always keep your cardboard clean and dry; this makes a big difference.
- Don’t forget to break down and flatten your boxes before putting them in the recycling bin.
- Try to separate your recyclable cardboard from trash right from the start.
- Make sure to remove any plastic liners, packing materials, and extra tape.
- Schedule regular waste pickup or drop-off so you don’t end up with overflow.
Recycling cardboard the right way helps keep recycling streams clean, reduces waste, and ensures materials can be reused instead of sent to landfills.
Should Cardboard Be Disposed of In the Trash?
Cardboard should only be thrown away when recycling isn’t an option. Recycling is always the best choice because it reduces landfill waste and helps conserve valuable resources. Most clean, dry cardboard can and should be recycled whenever possible. That said, some cardboard simply can’t be recycled. Items that are heavily contaminated with food or grease, coated with wax or plastic, or damaged beyond use may need to be disposed of properly.
When this happens, correct sorting is essential to keep recyclable materials out of the trash. Using the right mix of recycling and disposal containers makes waste management more efficient, keeps operations organized, and helps ensure compliance with local guidelines. By recycling what you can and disposing only of what you must, cardboard waste can be handled responsibly and effectively.
Summary
Recycling cardboard is a simple, effective way for homeowners and businesses to manage waste responsibly. Understanding the different types of cardboard and how to prep them properly really helps keep the recycling process running smoothly. Most clean and dry cardboard can (and definitely should) be recycled, but if it’s contaminated or coated, it’s important to dispose of it properly. With the right systems in place, businesses can reduce landfill waste, improve efficiency, and contribute to responsible waste management without complicating their daily operations.
