What Can't Be Recycled

18 Things that Can't Be Recycled and Why

We’ve become big on recycling in many places across the world as people seek to reduce the amount of waste they send to the landfill. They choose to recycle, or in other words recover and reprocess our waste for another use, instead and protect the planet. 

We can not overemphasize the advantages of recycling. It helps to conserve scarce resources such as trees, coal, and mineral ore. It also reduces pressure on landfills and contributes to a decrease in pollution. Typically, we can recycle glass bottles, plastics, aluminum, paper, and iron.

For the new recycling enthusiast, you may not imagine that anything is unrecyclable. However, a number of everyday items make it onto the list of things that can’t be recycled.  The major reason for this is that recyclers can’t make new materials out of them. Or sometimes the item is too difficult to recycle and not worth the resource and energy it requires. 

To ensure that you recycle the right way, it is important to know what can’t be recycled and how to handle such waste disposal. 

Here is a list of things that we cannot recycle simply by placing them in your curbside recycling bin. You’ll find many everyday household items. Some listed items may have special recycling centers, and collection from home can vary depending on your local council or municipality. Therefore, it’s always wise to check locally with the organization the delivers recycling facilities where you live. 

18 Things that Require Special Handling/Can’t Be Recycled

76% of batteries, especially lead batteries, are recyclable but require special handling because of corrosiveness and toxicity. When we don’t recycle batteries expertly, they can release toxins into the environment and endanger our health. Recycling facilities avoid batteries due to their corrosiveness. Never throw old batteries in the curbside recycling bin; they will end up in landfills. 

Ceramics and kitchenware

One important quality of kitchenware is the ability to withstand high temperatures. This quality is what makes ceramics, bakeware, and oven-safe glass dishes unrecyclable. These items have a higher melting point than conventional glass. The energy required to melt down kitchenware is exceptionally high, which means processors will typically reject these products.

Medical waste

Most medical waste is considered biohazardous and therefore not reusable or recyclable. The safest practice is to send syringes, scalpels, and other medical waste straight to specialized recycling centers should they exist near you. And where such a service provider is not available, properly dispose of them.

Food waste

Leftovers should never go into the recycle bin. They are not recyclable and contaminate other recyclables in the bin. To prevent food waste contamination in the recycle bin, you should remove food bits from items before putting them in the recycling bin. We can put food waste to good use as compost. If you don't need the compost, you can sell it to gardeners for some extra cash.

Greasy cardboard

Paper plates or food boxes soaked with oil or contaminated with food like cheese don’t make the recycling cut. This is because the food particles can contaminate other items in the bin or even damage recycling equipment. Oil and grease make it impossible to recycle paper, as they don’t mix with the water required to turn paper into a slurry. 

Unless you are prepared to take your time to remove every part of the cardboard soiled with food, it is best to put the greasy paper in the compost bin. For most places, there are very few companies that can recycle greased-up pizza boxes. Consult your local recycling agency to know if you have such special recycling centers in your area.

Waxed cardboard

They wax cardboard juice boxes, soup cartons, and milk cartons to prevent the paper box from soaking up the liquid. The wax, however, does not break down like paper, so it makes recycling very difficult. Recycling facilities for waxed cartons are not always available. Only 62.1% of households in the US have access to such facilities. 

Eco-cycle, which accepts milk and juice cartons, will not take cartons to package soup, rice, almond, and soy milk. 

Shredded paper

Shredding paper decreases the fiber length and reduces its value to recycling companies. Paper mills find sorting shredded paper a difficult task, so they often refuse it. If you must recycle shredded paper, you will need to locate a recycling center in your area that specializes in that aspect of paper recycling. 

Brightly colored paper

Adding paper with rich, bright dyes to the slurry guarantees that the end product will have an odd color. Knowing that most consumers prefer pristine white paper or at least a slightly off-white shade makes brightly colored papers a no-no for paper recycling mills. 

Used Paper towels and plates

Composting is the easiest way to deal with single-use paper products like paper napkins, plates, cups, tissues, and towels. Recycling them is challenging because of the high amount of food residue they usually contain. A little bit of food-soiled paper can make the entire content of the bin unrecyclable.

Also, it is impractical to try recycling wet paper. Water will cause the paper to break down rapidly, making it hard for recyclers to measure and process. Also, wet paper can easily become discolored, stain other contents of the bin or grow moldy.

Household glass

Lightbulbs, mirrors, window glass, and wine glasses are not curbside recyclable. They usually make these kinds of glasses to have a higher melting point than regular glass. 

However,  Fluorescent light bulbs have special recycling programs, and you will need to find out if any of these programs exist in your area. However, you’ll find most of these fragile items not only impractical to recycle but they get easily damaged beyond most kinds of reuse.

You can recycle mason jars, but there is no system for recycling other kinds of household glass presently. You may find crafts to do with broken mirrors and windows or damaged light bulbs. 

Plastic bags and wraps

Considered lightweight, plastic bags and wrappings are not suitable for curbside recycling. Bubble wrap, plastic wrapping, mesh produce bags, plastic bags can easily get tangled in recycling machinery and cause damages. Some local grocery stores may have special collection bins to recycle plastic grocery bags, and if not, there are many creative ways to reuse plastic bags and wraps at home.

Most flexible plastic packaging like potato chips bags, food pouches, crinkly bags, and candy wrappers are not recyclable. This is because they make them with layers of different materials that make them difficult to recycle. 

Hazardous chemicals

You can not recycle items that contain substances that are poisonous, flammable, corrosive, and toxic. These include motor oil, oil paint, pesticides, fuel, or poisons. It is advisable to take extra caution when disposing of packaging or containers of such substances. 

Aerosol cans with products in them, no matter how little, are unrecyclable. To make your aerosol cans recyclable, you need to empty the contents.

Plastic toys

The problem with recycling plastic toys arises from the tiny parts they contain. These minuscule pieces can clog the recycling equipment and cause severe damage.

Clothes hangers

Wire hangers are challenging to recycle. They could cause damage to recycling machinery. Most recycling centers do not have the machinery or capacity to recycle them. The shape of plastic hangers also makes them difficult to recycle. It is better to keep hangers out of your curbside recycle bin. They end up in the landfill otherwise.

Although in places like New York City, you can put your old plastic hanger in the curbside bin for recycling.


You can’t recycle clean or dirty diapers. Dirty diapers can contaminate other items in the bin and be unpleasant for the people who recycle waste to sort. 


Recycling electronics require special equipment and processes because they contain highly specialized materials. You should never put them in your recycling bin as they can cause fires.

Ropey items

Electric cords, headphones, chains, wires, Christmas lights, and garden hoses are notorious for tangling with machine parts. Therefore, most recycling centers tend to steer clear of them.


Clothing articles usually have special recycling programs, and you may not be able to recycle them just by throwing them in the curbside recycle basket. Some fashion brands provide recycling services, but If you do not have access to such, you should consider donating to thrift stores. 

Plastics that cannot be recycled

Many people make great efforts to recycle plastic, but some types of plastic waste cannot be recycled. Plastic products usually have a number between 1-7 on them; we call these numbers resin identification codes.

It is easy to recycle #1, polyethylene terephthalate (PET), the plastic commonly used in bottles and plastic food jars. Also, #2, high-density polythene (HDPE), from which shopping bags, grocery bags, and shampoo bottles are made, is easily recyclable as well. Products like reusable containers, medicine, and syrup bottles are made from #5 polypropylene (PP).

# 3 Polyvinyl chloride (PVC)

Shower curtains and liners, pipes, clamshell containers, blister packs, and medical shrink wraps are PVC products. The plastic is often mixed with phthalates to make it flexible. Combining PVC with other materials makes it difficult to separate and recycle, so they do not often recycle it.

#4 Low-density polythene (LDPE)

Manufacturers make bin liners, packaging, squeezy bottles, and toys LDPE. We also use it as a coating for milk boxes and coffee cups. Most LDPE products are easily contaminated and are difficult to recycle. However, you can check if your local grocery store has a program to recycle this kind of plastic waste  

# 6 Polystyrene (PS)

Some items made from polystyrene are styrofoam plates, packing peanuts, coffee cups, plastic straws, foam egg cartons. They rarely recycle this type of plastic in the UK.

Styrofoam items are not very durable, but you can reuse them. Some shipping companies or small businesses may accept clean packing peanuts.

# 7 other

They assign plastic goods that do not fall into any of the other 6 categories, the number 7. These include nylon, polycarbonate, bio-plastics, and other mixed plastics. Plastics in this category are not easily recyclable.


Not everything is recyclable, everywhere, even though we wish they were. For many of us, the recycling bin is the only access we have to recycle services, so it is essential to know what can and cannot be recycled. Please find ways to dispose of or reuse non-recyclable items safely.
