The next CVSan Recycles Day for Alameda County (residents only) will be held at Canyon Middle School on Saturday, August 13, 2016, from 8:00 am – 2:00 pm.

Acceptable items for CVSan’s August 13th Recycles Day drop-off are:

Yes: Old, expired, or unneeded prescription and non-prescription drugs accepted. Please empty pills into zippered bags and recycle plastic containers. Liquids, ointments, and powers are to remain in their original containers.

No: Health and beauty aids, vitamins, nutritional supplements, digestive aids, herbal remedies, illegal substances and paraphernalia, infectious waste, business/institutional waste, medical devices and equipment, personal care items, and radioactive materials.

Note: Residents to remain in their vehicles during pharmaceutical collection.

CVSan is now co-sponsoring the collection of pharmaceutical waste from a free public collection box located at the new Eden Medical Center.

The safe management and disposal of pharmaceutical (medicine) waste is important to Castro Valley Sanitary District and our community. Please do not dump any pharmaceutical waste down the drain or in the garbage. Castro Valley Community Action Network (CVCan) has found: “Improper disposal (of pharmaceuticals) can lead to pharm abuse, accidental poisonings and groundwater/bay pollution.”

Thanks to the partnership between Castro Valley Sanitary District (CVSan), Eden Medical Center, and the Alameda County Medication Disposal Initiative Workgroup, you can drop off your pharmaceutical waste at Eden Medical Center for free 24 hours a day, 7 days a week.

The location of the free public collection box is:
Eden Medical Center
20103 Lake Chabot Road
Castro Valley, CA 94546

Drive up the main driveway to the Parking Garage. Park in the Medical Center Parking Garage on Floors 5 or 6.
Walk right across to the Emergency Entrance where the collection box is located (shown below).
Please note the following guidelines below when disposing of pharmaceuticals.

Note: While CVSan highly recommends taking your unwanted pharmaceuticals to the drop box at Eden Hospital or another take-back location or event such as CVSan Recycles Day (see event details as actual collected items which may vary), it is not illegal at this time to place them in your garbage cart.  If you are unable to take the pharmaceuticals for proper disposal, you can mix any unused medicines with your garbage so no one will be tempted to take them out.  Also, if the medicines are placed in your garbage cart, they should be contained and to protect your privacy we recommend that you blackout or remove the labels on prescription containers.
