Recycling is the process of collecting items that would otherwise just be thrown away as trash and processing those materials into new products. It is important to understand that just because you put something into your recycling bin does not mean it will in fact end up being created into a new product.

RR-Blog-Icons-05102022-2Is it really beneficial to the environment?


According to the Environmental Protection Agency, that’s an absolute yes! Data has shown over and over that recycling conserves energy and natural resources. Recycling cardboard only takes 75% of the energy needed to make new cardboard for example. More energy is needed to produce cardboard from a tree than what is required to manufacture it using recycled materials. Products being recycled often do not require as much processing to turn them into usable raw materials.

RR-Blog-Icons-05102022-3I’ve seen headlines that recycling isn’t cost-effective. What does that mean?


This isn’t a new debate. For years, the costs and benefits of plastic recycling have been looked at for example. It comes down to how much it costs to collect, transport, sort, break down, and reform into new products. It also involves the supply and demand of materials. It is cheaper in many cases for a petrochemical company to make virgin plastic from oil than it is to use recycled material to create products. 


On the other hand, a well-run and properly managed recycling program can be cheaper than other forms of waste disposal. Recycling metal and glass is absolutely cost-effective. Aluminum can be recycled indefinitely and takes as much as 95% less energy to produce products than using virgin material. Glass is highly recyclable in a way that doesn’t lose quality each time it’s broken down. Beyond dollars and cents, other factors to consider in the debate are the impacts on people and the environment.

RR-Blog-Icons-05102022-4Can recycling help my business?


The short answer is yes! Recycling can reduce your operating costs. You’ll generate less trash which means dumpsters take longer to fill up. They won’t need to be emptied as often meaning lower waste disposal bills. Recycling elevates your company’s image and improves your Environmental, Social, Governance (ESG) rating. Major Wall Street companies are now tracking investor behavior related to a company’s environmental impact. Implementing a program in your office can be easy, fun, and helps your bottom line.

RR-Blog-Icons-05102022-5What’s the difference between single-stream and clean-stream recycling?


Single-stream recycling is easy on the consumer. Everything gets put into one recycling bin that gets emptied. The materials are mixed together meaning it takes longer to sort and therefore costs more money. It often results in contamination resulting in lower prices for the material and much of it is sent to the landfill.


Clean-stream recycling, on the other hand, requires more effort from the consumer. In this method, recyclables are separated based on the material. Each material has its own bin and the program can be customized. The materials are then taken to a facility where they are already sorted. That means the process is quicker, it costs less money, and the materials retain more of their value making them more in demand.

RR-Blog-Icons-05102022-6What can be recycled? 


This isn’t an exhaustive list and the best advice is to check with your local municipality, borough, city, or town to find out what is and what is not recycled where you live. Additionally, just because your recycling program doesn’t accept an item doesn’t mean it can’t be recycled. You may have to find a specialized facility, drop-off location, or event near you. 


Here are items that are widely accepted in recycling programs:





Junk mail

Phone books



Flattened cardboard


File folders


Frozen food boxes

Milk cartons

Plastic bottles, jugs, tubs, cups

Milk jugs

Soda bottles

Water bottles

Shampoo/soap/detergent bottles

Glass bottles and jars

Metal cans

Aluminum cans

Tin cans

Scrap metal

RR-Blog-Icons-05102022-7What can’t be recycled? 


The answer depends on a number of factors including location, cost, size, condition of the materials, and so on. 


While the majority of these items are typically not acceptable in curbside recycling programs, you can often find places nearby that will recycle some of these things. Take a few seconds to do an internet search and you’ll likely find a facility or hard-to-recycle event close to where you live. Don’t just blindly throw things into the recycling bin either. It causes contamination and the whole load will just end up in the landfill.


Here is a general list of items typically NOT accepted in curbside programs:



Aerosol cans that aren’t empty


Bubble wrap

Broken glass

Bowling balls

Christmas lights

Wire coat hangers


Electrical cords


Food waste

Food wrap

Garden hoses


Plastic bags

Polystyrene (styrofoam)

Propane tanks

Rubber balls

Sports equipment

Stuffed animals


Razor blades



Yard waste

RR-Blog-Icons-05102022-8Why can’t I put plastic bags in my recycling bin?


Single-use plastic bags shouldn’t be put in your bin because they can wreak all kinds of havoc at facilities. They can often clog equipment and get tangled around moving parts. This causes equipment to break and forces shutdowns until things can be repaired. During that time, the materials are then simply diverted to the landfill or pile up, causing a backlog that takes longer to process. Many local grocery stores offer bins in which you can drop off plastic bags to be recycled.

RR-Blog-Icons-05102022-9What should I do with my pizza box?


How greasy and cheesy is the cardboard? If it’s only lightly soiled or is in great condition, you can recycle the whole thing. Sopping with grease? Toss it in the garbage. Even consider cutting or ripping off the soiled part and recycling the rest of it. Pizza boxes are cardboard, a highly sought-after material that can be recycled into new products. Your best bet is to contact your local recycling company or facility for more information.

RR-Blog-Icons-05102022-10Are clothes and shoes recyclable?


Don’t put them in your bin. Textiles, much the same as plastic bags, will snarl equipment causing it to break and shut down. Instead, find a charity that will take gently used items. Some retail stores like Nike have bins inside where they will accept and recycle shoes. A quick internet search will give you a few places close to where you live where you can drop off items.

RR-Blog-Icons-05102022-11The arrows on a plastic container mean it is recyclable, right?


Not so fast. Just because it has a number inside the arrows does not mean it is recyclable. Called the Resin Identification Coding system, manufacturers stamp a designated number on their product to indicate what it’s made out of. Plastics 1 and 2 are widely accepted by most recycling programs. You’ll have to find out on your own if Plastics 3 through 7 are accepted. If not, there may be a place nearby that will collect it. No one regulates the symbol, however, so any company is free to place it on their product.

RR-Blog-Icons-05102022-12What happens after they collect the items from my recycling bin?


The items get trucked to a Material Recovery Facility (MRF) located nearby. At the MRF, humans, and machines sort the recyclables by their different material types. Bottles and cans are crushed to create what’s called a bale. The materials are then sold to companies that process them and create new products.

RR-Blog-Icons-05102022-13What can be made from the stuff in my recycling bin?


Everything around you right now could be made from recycled material! Cardboard is typically used to make new cardboard, paperboard, and paper bags. Newspapers can be made into telephone books, construction paper, and egg cartons. Plastics can be made into new milk jugs, water bottles, and even benches and playground equipment. Recycled glass is used in road construction, new glass containers, flooring, and pipes. Constantly evolving technology and a growing emphasis on a circular economy means the list of items that can be made from recycled materials is always expanding.
