Recycling for Faculty and Staff

Recycle More! Started August 1st, 2012. 

We've made recycling even easier! You can now recycle all plastic containers, boxes, paper, aluminum and glass. Use the Mixed Containers bin for plastic containers, glass containers, aluminum and foil.  Use the Mixed Paper bin for cardboard, paper and cartons.

Recycling FAQs: 

What's Changed?

You can now recycle more plastics!
In fact, you can now recycle all plastic containers  up to 2 gallons. Don’t worry about the numbers  or the little triangle. Is it a plastic container? Is it  2 gallons or smaller? If so, recycle it! This means  you can now recycle plastic jars, tubs, cups, yogurt containers, egg cartons and take out containers too.  Just make sure you dump your food waste into the trash before recycling.

  • bottles – e.g. soda, shampoo, water
  • jugs – milk, juice, detergent
  • jars – mayo, peanut butter, jelly  
  • tubs – butter, ice cream, margarine  
  • plastic take out containers  
  • iced coffee cups  
  • yogurt containers  
  • plastic egg cartons  

What shouldn’t I recycle? Why?

It’s actually a pretty short list! But there are some key items that can’t be recycled, these include:

  • Plastic bags - Plastic bags are made of such low quality plastic our recycling brokers can’t use them.  You can take them back to the store.  CVS on Thayer will recycle them, or better yet, bring your own reuseable bag!

  • Hot/coffee cups - these cups are coated or treated with a chemical that prevents them from breaking down when wet – precisely what recyclers need it to do! For this reason, hot cups are not accepted for recycling.

  • Styrofoam - the market for recycling Styrofoam is very small because it is hard to reuse.  Try to avoid it by bringing your own mug or container when eating out.  If you can't reduce your Styrofoam use, check out the RIRRC Recyclopedia for local recycling options.  

  • K‐cups, oatmeal and chip canisters (Hybrid packaging i.e. metal/paper/plastic mix) – The general rule of thumb is this: The more materials used to make a single package, the harder it is to both sort it and to find a recycling market for it.

  • Refrigerated and frozen food boxes – e.g. butter, pizza, soda, TV dinner - these boxes are coated or treated with a chemical that prevents them from breaking down when wet – precisely what recyclers need it to do! For this reason, refrigerated and frozen food boxes are not accepted for recycling.

  • Greasy pizza boxes - The grease from the pizza is the problem. Paper mills use water to mush down your cardboard back into pulp, and oil and water don’t mix! For this reason, greasy cardboard is a contaminant to our paper buyers and is not accepted for recycling. If the top of the box is entirely clean, please do rip it off and place it in your recycling bin, throwing the greasy part in the trash.

  • Chip bags and candy wrappers - these are most often hybrid materials (see above) and there is only a very small niche market for them.  If you are a hard-core recycler you can check out TerraCycle to see how to start your own collection for these materials.  

    If you find yourself frequently purchasing an item that is not recyclable for these reasons, contact the company directly and let them know you’d appreciate seeing packaging for their product in a single material that is more easily recycled. 

I work in a research lab.  Can I recycle containers from my lab? 

When working in labs, safety is the first priority.  Make sure to follow all EHS guidelines.  You can recycle non-hazardous (no p-list, radioactive or bio-hazardous) containers and materials.  Clean and dry glass can be placed in the designated glass box.  Plastics and aluminum can be placed in the “mixed container” bins in the hallways and stairwells.

What about “compostable” or “biodegradable” containers? Can I recycle those?

No.  Plant-based compostable and biodegradable containers, like the to-go cups and boxes you get at the Ratty or Blue State Coffee, are designed to break down in natural environments.  Please throw them in the trashcan; because they have a different chemical composition they can’t be recycled with normal petroleum based plastics.  

Not sure if your container is “compostable” or “biodegradable?"  Check the bottom! It should be written there.  

Why is this different than what I do at home?

Many states, including Rhode Island, have different recycling systems for the residential and commercial sectors.  Since Brown is a private non-profit, we are responsible for collecting and recycling our own waste.  Recycling rules also vary from state to state. Learn more about what and how you can recycle at home: 

Why do I have to sort my recyclables?

Sorting helps to maintain the high quality of our recyclables. At Brown, we set the goal of saving resources by using recycled material to make new things. Separating fibers (mixed paper and cardboard) from containers keeps both streams of materials in better shape.  This makes our recyclables more attractive to the companies that purchase these materials. This way Brown makes more money and more of the things you put in the recycling bin actually get reused.  

Why recycle? Does my one bottle really matter? 

Yes! Every can and bottle counts.  Extracting the natural resources needed to make paper, plastic and aluminum uses a lot of energy.  Recycling one aluminum can saves enough energy to power your laptop for 5 hours! Check out this EPA widget to calculate your saving power. 

Where does our trash and recycling go?

At Brown, our waste is collected by a local company called Waste Haulers. They truck our recyclables to their transfer station in Pawtucket, RI where they are  sorted, processed and packaged to be sold to industries that use recycled materials. Our trash is incinerated at a waste-to-energy facility in Massachusetts.

What should I do if I don’t have a recycling bin or I see a place on campus that needs one?

Call the Service Response line at (401) 863 -7800 and let them know what you need. If you want, you can forward the e-mail confirmation you receive after the call to so we can help you follow up!

My recycling bins need better signage.  What can I do? 

You can download and print our 11x17 Office Recycling sign.  If you would like a laminated copy of this sign sent to you via internal mail, please e-mail 

How much stuff does Brown recycle each year?

Last year, Brown University diverted 43% or 1,508 tons of solid waste from the landfill by recycling construction debris, bottles, cans, paper, cardboard, electronics, food scraps, yard trimmings, and miscellaneous items such as clothing, furniture and bedding. 

What are the biggest problems with recycling at Brown?

We lose a lot of our recyclables to the incinerator because our recycling bins are contaminated with trash and food waste. If a bag of recyclables has more than 5% food waste contamination, it’s too messy to recycle. The whole bag gets thrown in the incinerator. You can help by making sure you NEVER throw food in a recycling bin!
