The Do Not Recycle List: What to Keep Out of Your Recycling Bin

Don’t Recycle!

Does that command startle you a little bit? It almost seems heretical to refrain from recycling products and materials which you have already used and/or are ready to discard. After all, we’ve all heard the recycling mantra repeatedly from those who constantly implore us to do our part to save the planet. 

Recycling binWait. Recycling can be bad?

While we may be forgiven in thinking that practically everything can be recycled these days, the fact is that there are plenty of items which should not be tossed into your recycling bin. In addition, there are some materials which may technically be recyclable, but are not cost-effective for most facilities to handle and therefore should be put in the trash.

Here is a list of things which you should avoid placing into your recycling container:

  1. Wet paper. Paper is recyclable because the fibers from which it is constructed can be extracted and used again. But that’s harder to do if the fibers are wet.
  2. Shredded paper. Similarly, those tiny pieces of paper means that the fibers are more difficult to extract – so it becomes inefficient to try and recycle material that has been fed through a shredder.
  3. Brightly-colored paper. You know what happens if you put a dark shirt into a load of white socks? Same with paper. In fact, the dyes in a small amount of colored paper can contaminate an entire batch of recyclable paper.
  4. Used napkins or paper plates. Food is even a worse contaminant than dyes. And since there’s no telling what types of food were placed on a paper plate or wiped by a napkin, these items should be trashed instead of recycled.
  5. Pizza boxes. These are especially problematic because almost every pizza contains a fair amount of greasy substances. That grease won’t mix with the water that is used during the recycling process.
  6. Paper coffee cups. The quality that prevents hot liquid from seeping out of them is the same thing that makes them non-recyclable: a thin polyethylene coating on the outside of the paper.
  7. Milk cartons and juice boxes. The waxy packaging does not play well with many recycling machines. However, some facilities have begun accepting these items, so it’s worth checking to see if you can add these to your recyclables.
  8. Shipping envelopes. Those cardboard-like envelopes used by shipping companies and the postal service? They contain Tyvek, a waxy film that is designed to repel moisture but which doesn’t separate well in the recycling process.
  9. Disposable diapers. Yes, these do contain some plastic and paper that could be recycled; but it’s too much trouble for recyclers to remove it from the rest of the diaper.
Recycling bin
No, recycling centers don’t want that nasty thing. Throw it out.
  1. Water bottle caps. Again, some recycling centers don’t mind these caps. But since they’re made of a different type of plastic than the bottles themselves, you should take the caps off of them before putting them in a recycling bin just to be safe.
  2. Aerosol cans. It’s true that many types of scrap metal can be recycled, but the metal in aerosol cans is always assumed to be contaminated with whatever chemicals were put inside them. So just throw these cans in the trash.
  3. Ceramics. Coffee mugs, cereal bowls, plates, flower pots, and other ceramic items cannot be broken down and recycled. But you may be able to reuse them for other purposes.
  4. CFL light bulbs. They’re eco-friendly because they use less energy to power them. But since they contain a small amount of mercury, they should never be placed in a general recycling bin (although some places do recycle CFL bulbs specifically).
  5. Batteries. Some alkaline batteries can be taken to electronics centers for recycling. But this process is much different than the one used by general recycling machinery, so keep batteries out of recycling containers.
  6. Plastic bags. This kind of plastic is not recyclable. Worse, these bags tend to clog the mechanisms in the recycling machines and even shut these plants down in order to extricate them.
Recycling binIt’s not a trash can, people. So treat it with respect.

You probably have nothing but the best of intentions when it comes to recycling. But if you include non-recyclable items along with those which can be recycled, you may be doing more harm than good.

1 Million+ Satisfied Customers Nationwide

I recently had the Gutter Helmet by Harry Helmet installed on my house. It not only looks amazing, but the guys arrived on time, were professional and efficiently got the job done. I am very satisfied with Gutter Helmet's attention to detail and fulfilling their work as promised. I will definitely tell my neighbors about the Gutter Helmet.
I have had Gutter Helmets for 20 years. In all that time I've never had a problem until recently a bird's nest found its way into one of my gutters. The installer who came to replace the product was the same installer from 20 years earlier. Now that's impressive. Everyone at Gutter Helmet inclusive of the office staff were professional and a pleasure to work with.
Gutter Helmet by Harry Helmet just replaced our roof and we could not be more satisfied. The crew showed up early, worked all day and stayed late, were professional and caring regarding the project and the surrounding impact it had on our property and home. They completed the roof quickly and it looks simply amazing!
VERY happy with our entire experience adding Gutter Helmet by Harry Helmet to our house. Installing this was a great value for us. The gutters are working perfectly in heavy downpours and with year-long leaves and debris coming down from our river birches. Terrific customer service and a first class product.
We needed our roof repaired due to wind damage. After several quotes, Gutter Helmet was the only company that went into our attic to look and see if more damage had occurred. If it wasn't for them taking the extra time to look at everything, we would have had rotting wood under our new roof. They were very professional and gave a fair quote.
We just had Gutter Helmet installed on our gutters and couldn't be happier. They provided us with useful information about Gutter Helmet and cleaned up everything, leaving no mess behind. We definitely recommend Gutter Helmet to anyone considering this product.
