I have a stack of carbonless copy forms that I can't use. Is it harmful to recycle this kind of paper?

Quick answer: Nope, carbonless paper can be safely recycled like most other paper.

What is carbonless paper?

Carbonless paper is typically used when filling out forms. It consists of sheets of paper (usually of different colors) that are coated with micro-encapsulated dye or ink and/or reactive clay. Pressure applied to the top sheet breaks tiny micro-capsules on the backside of the paper, which then react with the clay on the top the next sheet to form a permanent mark. This is repeated for however many sheets are in the stack, often resulting in stronger markings near the top sheet and fainter markings near the bottom sheet. Carbonless paper can be used for longhand as well as mechanical writing, such as typewriters.

Carbonless paper should not be confused with carbon paper, a black inky sheet placed between two sheets of paper to make a pressure copy. Carbon paper cannot be recycled.

What's the deal with polystyrene?

On Earth Day, Palo Alto issued an ordinance that restricts food vendors from providing take out containers that are made from expanded polystyrene or non-recyclable plastic. This ordinance affects a broad umbrella of food service vendors such as retail food vendors, cafeterias, outdoor food vendors, food vehicles, and caterers. While the ordinance applies to containers, it does not apply to straws, utensils, or hot cup lids. These vendors are expected to comply within a one year period.

What is Polystyrene?

Polystyrene is an inexpensive and commonly manufactured plastic; companies make items like clear disposable cups, razors, and CD cases out of polystyrene. The take-out containers in question are made of expanded polystyrene foam, and are of the same material as packaging peanuts and insulation. While this product is very similar to what is commonly known as Styrofoam, it is different because of its beaded texture.

What is the problem with it?

While this foam is good at keeping your food hot or cold, it causes a number of significant issues for ecosystems. What makes it convenient and durable for humans is what makes it so problematic for the environment; it is lightweight, it floats, and it can easily break into smaller pieces from factors like wind and sun. When these pieces break down, they can be mistaken for food by marine and land animals. It is non-biodegradable, so it will not break down in the environment like plants and other compostable matter. Even though some recycling companies will accept the plastic (polystyrene is the #6 recycling category), the expanded foam that is contaminated by food is nearly impossible to recycle. So, most containers either wind up in landfills or as litter; polystyrene containers are currently the second most abundant form of beach debris in California due to their common and widespread use. Finally, some scientific studies suggest that styrene is a harmful carcinogen to both humans and animals.

What can I do?

If you're not in an area that bans polystyrene, you still have options. Invest in some reusable containers, or if the place offers it, get a paper container instead (like when you get frozen yogurt at Frozo's). Even though the ordinance is exclusive to expanded polystyrene, Styrofoam is no better. Avoid it when you can! While Bon Appetit offers compostable to-go containers, you can do one step better and sign up for our Eco-Clamshell program.

Here's how:

1. Sign up at Market Square. If you're a faculty/staff member, you can do this at Adobe Lodge as well. Bring your campus ID and a refundable ten dollar deposit. You'll be given a keychain to exchange for your first EcoTray.
2. Every time you make a to-go purchase at Market Square or Adobe Lodge, you exchange your keychain for a clean and sanitized EcoTray.
3. Once you're done, you can drop off the tray at any on-campus Bon Appetit venue during regular hours in exchange for a new keychain.

What do I do with clothes that aren't in good enough condition to donate to places like Goodwill?

Organizations like Goodwill and Salvation Army are happy to accept clothes in 'good' condition, which means they shouldn't be ripped or stained. However, for those clothes that have seen better days, there are still a number of options that will put them to good use:

  • 7th Generation Recycling accepts cotton clothing scraps, along with used clothing or textile items like pants, dresses, hats, shirts, drapes, curtains, blankets, towels, sheets, handbags, belts, paired shoes, and even stuffed animals! Conveniently, they have a green collection bin located on Lafayette St. near Frozo's.
  • Contact your local animal hospital. Some will accept clothing scraps to use as bedding for hospitalized animals.  

You can also reuse old clothes in the following ways around your home: 

  • Old tshirts are great to cut up and reuse as cleaning rags.
  • Use them in arts and crafts projects.
  • Save the buttons in case you lose some from your other clothes.

Be creative! These are only a few suggestions out of an infinite number of possibilities for reuse!

Are CD's recyclable?

Currently, our Facilities department does not accept CD's as recyclable materials. However, there are a couple different options for you to recycle or reuse CD's:

  • If you're getting rid of store bought CD's (with the case and paper insert), you can donate them to a used CD store, or bring them to Goodwill/Salvation Army.
  • Or, you can send them to: 

             The Compact Disc Recycling Center of America
             68H Stiles Road
              Salem, NH 03079 
              http://www.cdrecyclingcenter.com/

              This center will recycle the case and paper insert as well!

  • If you want to really get creative, here is a page with lots of suggestions for how to reuse the disk.

I'm always washing my reusable coffee cup and drying with paper towels. Are we sure that's better for for the environment than tossing paper cups?

Water is part of a cycle. The water cycle is a natural process, rain flows to rivers, rivers flow to bays, water is evaporated and forms precipitation as rain, etc. We manipulate the system with our municipal utilities (like using tap water) but, used (or wasted) water ultimately goes down the drain and out into the bay, and back into the water cycle. Yes, it's good to conserve water use. But when comparing to other wasteful practices, it's important to consider the larger system/cycle.

Paper cups aren't part of a cycle. When you're done with them, they get hauled to a landfill where they sit forever. Things never breakdown in a landfill. So using a one-use cup is not cyclical... Even if it's a compostable cup, it's still going to sit in a landfill. Unless you can compost. That's a whole can of worms (literally, ha).

I'd recommend to keep on keeping on with your reusable cup and minimize the washing/drying if you can. Otherwise, you're better off continuing with what you're currently doing (but try a reusable towel)!

Are napkins and paper towels compost or waste?

Napkins are compostable because they break down easily and are typically used with food.

As for paper towels and facial tissue, that depends on how you're composting. They are technically compostable and are fine to put in compost if you're making your own. However, for large scale composting (like we're doing at SCU), they should be considered waste as they can contain pathogens.

Is there a charge on very large E-Waste?

E-Waste is treated the same no matter what the size; there are no limits or extra charges depending on the size of it.

Students in the residence halls should place e-waste in the designated spot in their recycling and waste area (there should be a sign that reads "e-waste")

Faculty and staff should contact Facilities at extension 4742 or email facilities-csc@scu.edu to arrange for a pick up. If you are set up to use FAMIS, you can also submit a work order directly to Facilities.

Should paper towels be placed in the trash or compost bin?

We cannot compost paper towels from bathrooms, so they need to go in the trash.

Napkins (and paper towels other than those used in bathrooms) are compostable.

When will academic buildings get compost containers?

SCU started our compost collection program in May 2009. We began by collecting compostable waste from the kitchen in Benson Center. In September, we expanded our compost collection to Market Square and all residence halls.

SCU's composting program is still new, and we're phasing it in slowly to give the campus community time to adjust to our new waste diversion practices!

Academic buildings are undergoing a transformation to a new desk-side recycling and waste collection system. As we phase in a new building, we are adding compost collection containers in those buildings' kitchen/break rooms. All academic buildings will be transitioned this academic year.

Does extra butter and the butter wrapper go in the trash or in compost?

The extra butter goes into compost containers.

If the butter wrapper can tear easily (like paper), go ahead and throw it in the compost.
If it doesn't tear (or if it's made from foil), please put it in "landfill waste". If it looks like paper but doesn't tear easily, it's been plasticized and shouldn't be composted.

Also, check out this article about re-using butter wrappers for baking!

Can I recycle the compostable containers that hold the fruit and salads in Benson? Or should I just throw it in the trash?

UPDATE: You can now compost these containers! Look for the bright green compost collection containers in Benson!

Please don't recycle these containers! When bioplastics end up in recycling processors, they cause expensive problems for recycling facilities, so it is better to throw containers in the compost. If you can't compost, please put them in the trash.
