Cardboard Recycling: How to Recycle and Reuse Cardboard Boxes
Recycling is very important in the fight to stay green and counteract the effects of climate change. One recyclable item that basically everyone uses is cardboard. Cardboard recycling is very important as almost every company uses cardboard for shipping purposes. In fact, cardboard itself is, most times, made out of recycled cardboard or lumber industry byproducts. However, there are things that you need to know about recycling cardboard. Like, where to recycle cardboard boxes, or if cardboard fits in recycling dumpsters.
From basic boxes for storage to those multi-color card stock, cardboard is a great material that you can buy in many different sizes and use in a variety of ways. Cardboard is a term that refers to heavier paper-based products. Normally, during manufacturing, cardboard falls into one of three categories. Paperboard, cardstock, and the ever popular, corrugated fiberboard, also known as cardboard boxes.
How and What is it Made of?
All types of cardboard are made from the same material, wood. Usually from hardwood and sapwood. Paperboard, which is basically just thicker paper. By either chemical or mechanical means, the wood is made into a pulp, which is then put through a bleaching process. Once that is done, they remove the water from the pulp and press, steam heat and add starch or resin. Finally, the new material is put through rollers to smooth it out and voila, paperboard.
Corrugated Fiberboard is basically cardboard boxes. These boxes are made out of several layers of paperboard, usually two outer layers with an inner corrugated layer. However, the inner layer is made from a different kind of pulp than the paperboard. It results in a thinner paperboard which can not be of any use in any paperboard applications, but it is perfect for corrugating because it is easily be made into a rippled form.
Cardstock is the thinnest type of cardboard, but still thicker than regular paper. This form of cardboard is typically useful for postcards, greeting cards and even some business cards. So basically...cards, hence the name. The manufacturing is the same as it is for paperboard but is made to be thinner.
How to Recycle Cardboard
Most cardboard is recyclable. Recycling cardboard is the same as recycling anything else. Since most of the cardboard you are likely to recycle is bigger, you can place it next to your recycle bin. Where can you drop off cardboard boxes? Usually, your local recycling center will accept them. If not, you will need to ask them where you can take the cardboard boxes. However, there are some things you need to know when recycling cardboard. To understand these conditions, you first need to understand the process in which cardboard is put through recycling.
The Recycling Process
- Collection- This is the first step. Depending on where you live, your recycling might get picked up like your trash. If not, you must find and take it to your local recycling facility. Almost every facility will recycle cardboard.
- Sorting- One the cardboard is at the recycling center, it is sorted according to what materials it is made of. Usually it separates the large corrugated boxes from the thinner box/paperboard items.
- Pulping- The materials are then soaked in a mixture of water and chemicals to break down the fibers and make a pulp, much like the pulp used to manufacture the cardboard. What goes around, comes around. The recycled pulp is then mixed with fresh pulp made from wood chips. This helps the old fibers to strengthen and solidify again.
- Filter and De-Ink- The pulp is then put through a series of filters to remove any foreign materials like glue or tape. Once the pulp is clean, chemicals strip the inks and dyes from the old cardboard pulp.
- Finishing- The last stage is when the pulp is mixed with virgin materials and dried. A machine then squeezes out any leftover water and creates a solid sheet called linerboard. The new linerboard is shipped to manufacturing companies to be made into new cardboard materials.
Guidelines For Cardboard Recycling
So, now that you know the process of how the cardboard is recycled, time to clue you in on the guidelines surrounding cardboard recycling. Now surprisingly, you can not recycle all the cardboard you receive.
Boxes like the ones you get from Amazon are fine, same with birthday cards, egg cartons, that brown paper stuffing that people sometimes use as insulator. All of that is fine. However, dirty or wet cardboard, most place do not allow. So your greasy pizza box, that is a no. Other items on the no fly list are birthday cards that are glittery, or have batteries in them, as well as food or drink cartons. But the food and drink cartons can be washed out and then put out for recycling. Also, all cardboard needs to be flat before the cardboard recycling collection happens.
The reasoning behind these guidelines is because if the cardboard is severely wet or not flat, it can jam the sorting mechanisms during the sorting phase of recycling. In addition, the items that are dirty or covered in grease, the process is unable to clean the foreign material which renders the cardboard unfit for recycling. Glitter can also gum up the works. If you are still unsure about which items you can or can not recycle, contact your local cardboard recycling center.
