Are pizza boxes recyclable?

Yes and no. Empty pizza boxes may be recycled only if they are clean. You can separate the lid from the greasy bottom section for recycling and compost the greasy part. (Back to FAQ’s)

Are plastic bags recyclable?

Yes, but only if you bundle all of your plastic bags in a tied off plastic bag. This prevents the plastic bags from getting tangled in the recycling sorting machinery or flying away during the transportation process. (Back to FAQ’s)

Is Styrofoam recyclable?

No, Styrofoam is unfortunately not recyclable.  Most recycling facilities do not accept Styrofoam in their recycling programs because it is not feasible to recycle Styrofoam. Items are recyclable because 1) the product can be recycled into something new and 2) there is a market for the recycled product).  However, the bulky but lightweight structure of Styrofoam and other similar foam products make the material hard to process and there is very little market for recycled foam products. (Back to FAQ’s)

What about _____?

For more information, the L.A. County Department of Public Works has kindly provided a table of recyclable items to help you! Just click on the following link: LA County Recycling. You can also look at our waste hauler’s educational materials: Athens Signage (Back to FAQ’s)

Do bottles and cans need to be rinsed before being placed in the bins?

No, but please empty them first. All trapped liquids get squeezed out in the recycling process, but the liquids can cause contamination issues for the rest of the recycling load. 

(Back to FAQ’s)

Do I have to rinse out my recyclable containers before placing them in the bin?

It is not required to do this, though it is preferred if there is a lot of food or grease.  Drain liquids and scrape as much food out into a compost container (if available) or a landfill bin before recycling your container.

(Back to FAQ’s)

Can recyclables be thrown away in plastic bags?

Yes, however since bags will need to be opened to begin the sorting process, it is preferable that items are not placed in bags. (Back to FAQ’s)

Which plastics should be placed in the recycling bins?

Plastics #1, 2, and 5 are most likely to be recycled. #3 and #4 plastics are more difficult to recycle, but are still accepted. #6 and #7 plastics are extremely difficult to recycle and it is advised to dispose of these in the landfill bin. If you happen to recycle plastic is not recyclable, it will simply be sorted out at the recycling facility, but we want to keep to contamination low as possible! (Back to FAQ’s)

If the plastic that I am trying to recycle doesn’t have a number on it, can I still recycle it?

While plastics usually have a recycling number on them, if you only have a few of these items, it is safe to dispense them in a recycling bin. If it turns out that the plastic is not recyclable, it will simply be sorted out at the recycling facility. As a general rule, hard plastics (ones that will retain its shape if you squeeze it), are typically recyclable. Soft plastics, such as cling wrap and zip-top bags, are not recyclable. (Back to FAQ’s)

Should plastic or glass bottle caps be removed prior to being recycled? Should I flatten soda cans?

The bottles are recycled in one way or another but to prevent the bottle caps from being lost during transportation, please keep the caps on.

Do not flatten aluminum cans before recycling, as this will make it difficult for sorting machinery to recognize and sort the cans. (Back to FAQ’s)

Is it better to put biodegradable plastics with a #7 (PLA) in the recycle bin or the food waste bin?

Please put it in the compost bin if available. NOTE: Not all #7 plastic is compostable. Make sure product says “compostable” before disposing in food waste bin. (Back to FAQ’s)

Is worthwhile to place small items like straw wrappers into a recycling bin?

Yes, it is worthwhile to place small items in the bins. While some of the smaller items get lost in the sorting process, much of it makes it through. (Back to FAQ’s)

What is single-stream or commingled recycling? What are the benefits, and is this effective?

Single-stream is a fancy term for co-mingled or mixed recycling. Under this system, all recyclables can be placed into the same bin. They are then sorted on the back end by a waste management or recycling company. This “single-stream” is simpler and more convenient for the individual. It is highly effective and is used by many communities, schools, and businesses around the world. Using a single-stream system will help UCLA reach its 90% waste diversion (not going to a landfill) goals. (Back to FAQ’s)

Won’t there be more contamination if we put everything into the same bin?

Yes, there can be some additional contamination, but the increase in recycling collection makes up for it. Food and liquids are what causes “contamination” of recyclables and they should not be placed into the mixed recycling bins. (Back to FAQ’s)

Is single stream more energy intensive and more expensive?

Slightly, but the increase in recycling makes up for this. Landfill space is limited and so are our planet’s resources. This means trash will have to be trucked further and further away if we reach capacity with our current landfills. In addition, more raw materials will be required if we do not promote a circular economy. (Back to FAQ’s)

Where does our recycling go?

Recyclables are collected on campus from the recycling bins, and then taken to a Materials Recovery Facility in Sun Valley where they are sorted. From there, they are bundled and sold as commodities to be made into new products. Where exactly they go depends on the current market demand. (Back to FAQ’s)

Who sorts the recyclables?

We have a contract with our waste hauler to sort our recyclables at a nearby Materials Recovery Facility. (Back to FAQ’s)

What about compost?

Our waste hauler accepts compostable waste and preliminarily sorts contaminants at a Materials Recovery Facility before bringing it to their organics processing facility. UCLA has widely expanded access to compost bins throughout campus and will have compost collection in all campus buildings by the end of 2020. (Back to FAQ’s)

Requesting recycling bins

Facilities will provide recycling bins for public spaces only (corridors, hallways, and classrooms). Departmental space such as office suites and labs will need to purchase their own receptacles. If you need a battery bin, please fill out form here. (Back to FAQ’s)

What can I do if my apartment building doesn’t have recycling bins?

You can contact your building manager about receiving recycling services from your waste hauler. The L.A. County Recycling Ordinance mandates all waste haulers to provide this service, it also allows these haulers to charge a fee, but this fee is usually only between $0.50-$3.00 per month. (Back to FAQ’s)
