Yes, you can leave cardboard outside for recycling, but there are some important guidelines to follow to ensure that it is collected properly and recycled efficiently. Here’s what you should keep in mind: 1. Check Local Regulations Recycling Policies: Make sure your city or municipality allows for curbside pickup of cardboard. Some areas require cardboard to be placed in a specific recycling bin or to be bundled properly. Collection Days: Confirm the scheduled pickup day for recyclables in your area to avoid leaving the cardboard outside for too long. 2. Break Down Boxes Flatten Boxes: Flattening the boxes reduces the amount of space they take up and makes it easier for the recycling service to collect them. It also prevents issues with large boxes blocking sidewalks or driveways. Remove Non-Cardboard Materials: Remove any tape, stickers, or packing materials (such as plastic and foam) before recycling. While some minor tape is usually okay, too much of it can contaminate the recycling process. 3. Keep It Dry Wet Cardboard: Cardboard that gets wet becomes difficult to recycle because the fibers weaken. If possible, place your cardboard in a dry location (like a garage or under a porch) before recycling day. Use a Bin: If you don’t have a covered area, consider placing your flattened cardboard inside a recycling bin with a lid to protect it from the weather. 4. Bundle Large Amounts Bundling: If you have a lot of cardboard, you may need to tie or bundle it with string. Many curbside recycling services ask for this when there are multiple boxes to make it easier for the collectors. 5. Avoid Contamination Food and Oil: Don’t recycle cardboard that is soiled with food, oil, or grease (such as pizza boxes), as this can contaminate the recycling process. Clean, dry cardboard is ideal for recycling. 6. Follow Weight Limits Weight Restrictions: Some services have weight limits for curbside recycling. Make sure that your cardboard bundles or bins don’t exceed these limits, or they may not be picked up.
