Recycle Your Leftover Paint & Cans
Recycling your leftover paint in California is more convenient than it used to be. October 19, 2012 marked the first day of California's Paint Stewardship Program, kicking off with 335 retail collection sites across the state.
In Castro Valley, there are two PaintCare locations where paint is accepted during regular store hours only. There is no fee for dropping off paint at PaintCare locations, and the limit is 5 gallons per visit per day.
- Kelly Moore, 3090 Castro Valley Blvd., phone: 510-690-9249
- Dunn-Edwards, 20923 Redwood Road, phone: 510-881-0313
What’s Accepted: Interior and exterior architectural paint sold in containers of 5 gallons or less will be accepted (latex, acrylic, water-based, oil-based, enamel, deck coatings, primers, sealers, stains, shellacs, lacquers, varnishes, swimming pool paints, metal coatings, and rust preventatives).
Who Can Participate: Residents, trade painters, contractors, and businesses (that produce less than 27 gallons of hazardous waste per month) are eligible to participate. Both new and old paint can be dropped off, even if it is over 20 years old.
California’s PaintCare Program is a result of Assembly Bill 1343 (Huffman), passed in 2010. Leftover paint is a national problem representing 40-60%, by volume, of all HHW collected at public facilities. In California, it is estimated that paint management currently costs local governments $21 million each year. California is the first state in the nation to have a permanent paint stewardship program.
CVSan passed Resolution 3289 on August 7, 2012 in support of Extended Producer Responsibility.
Bring 'Em Back
When your old fluorescent bulbs go dark, don’t throw them in the trash or recycling bins. Instead, Bring them back to a participating retailer where they’ll be disposed of properly. It’s a great way to protect the environment and support local businesses. For more information on this program please visit www.bringembackac.org/.
In Castro Valley Bring 'Em Back to:
- Pete's Ace Hardware, 2569 Castro Valley Boulevard (Please drop off only during normal business hours. If you have large quantities of bulbs, place them in a box).
Dispose of HHW Safely, Conveniently -- and Free at the HHW facility!
Check your house, garage, and yard for common household products (such as cleaners, paints, car products, and pesticides) that may be hazardous to your children, your pets or the environment.
Words such as danger, warning, caution, poisonous, and flammable on the labels can mean a product is toxic. Label the toxic products you find as a reminder to use them up and dispose of them safely. Do not put such materials in garbage cans or storm drains.
