Recycling & Waste Reduction
Can I recycle plastic bags in the blue recycling cart?
No, Plastic bags are not accepted in the blue recycling bin; they jam the recycling sorting machinery. We encourage you to reuse them. After that, the plastic bags can go into the garbage, or you can take them to some grocery stores for recycling. Safeway, Whole Foods, Andronico’s and Trader Joe accept plastic bags for recycling.
Does the material I put in the Blue container really get recycled?
Yes, the paper, glass, metal, bottles, rigid plastics can all be toss in the blue recycling bins, which are separated by hand and by machine and sold to companies that make them into new products. Materials placed in the garbage, even if it contains recyclable materials, are not sorted, and go directly to landfill.
Do recyclables have to be rinse before placing them in the recycle bin?
No, it’s not necessary to rinse out the recyclables, but please dump out all food into your compost bin and pour non-oily liquids down the drain before putting items into the blue recycle bin. Doing so helps reduce smells and pest problems.
What do the numbers on the bottom of the container mean?
There are several types of consumer plastics or resin. The number you see on the bottom of the plastic container is an identification code for what type of plastic the product is made of, NOT a recyclability code. The code is used to sort the different plastics since each has different qualities that need to be considered when utilizing it for new products.

If you don’t have pest problems with your garbage you shouldn’t’t have pest problems with your green bin. However, to minimize pest problems such as fruit flies UCSF lines the bins with compostable bags to collect food scraps. Also, compost containers are serviced nightly. The custodian periodically washes the cabinets that hold the plastic bins.
