Less-Toxic Solutions
The ultimate solution to the household hazardous waste problem is to reduce dependence on toxic/hazardous products and use them only when necessary. Disposing of these products, even through our program, should be viewed as a last resort. Use less toxic/hazardous alternatives whenever you can and only purchase those toxic/hazardous products in small quantities and use them to completion.
The following are a few tips to help you reduce the amount hazardous chemicals you have in your home and the amount of HHW you produce.
- Do away with or limit the use of household products that contain hazardous chemicals. Instead of using a caustic drain cleaner use a metal snake instead. Instead of purchasing the large can of product purchase the smaller size. You will be more likely to use this can up more quickly and not have to store the chemical in the home for long periods of time. Check out these web sites to learn more about household products:
- Purchase less toxics products. These products are safer for the environment and safer for you. It is good to purchase products that have had life cycle analysis performed on them. Look for products that contain less toxic chemicals. Some common “green certification” web sites include:
- You can also search for less toxic and more sustainable products by visiting Consumer Reports at http://www.greenerchoices.org/
- Shop at stores that are more environmentally friendly. Palo Alto Hardware has a whole line of green products that are safe for the environment as does Country Sun Natural Foods and Whole Foods Market to name a few.
- For a list of “Green Businesses” click on the following link: http://www.greenbiz.ca.gov/ShopGreen.html
- When purchasing paint ask the sales professionals to help you calculate your coverage amount. Coverage amount is the calculated volume of paint needed to paint a given square footage. This saves you money and you purchase only what you need!
- The most difficult types of household products to recycle are cleaners, corrosives, and poisons (including fertilizers, pesticides, and medicines). It is important to use these types of chemicals sparingly and to completion.

Program Goals
The Household Hazardous Waste (HHW) Program is an integral part of the City’s Comprehensive Plan relating to environmental concerns. Some of the comprehensive plan HHW references include:
- GOAL N-6: An Environment Free of the Damaging Effects of Biological and Chemical Hazardous Materials. “Palo Alto will also continue its household hazardous waste collection programs and will strive to make these programs more convenient and accessible to residents” (page N-21).
- PROGRAMS N-23 and N-28 relate to water quality issues and list Best Management Practices (BMPs) necessary to achieve the program objectives. Water quality issues of concern include the illegal disposal of pharmaceuticals, pesticides, poisons and other environmentally harmful chemicals into the sanitary sewer via sinks or toilets. The HHW Program is one of the primary BMPs listed in the plan necessary to meet these clean water objectives (page N-16).
- PROGRAM N-48: “Continue sponsoring a regular household hazardous waste collection event” (page N-22).
- PROGRAM N-50: “Continue the program that allows small quantity generators to dispose of hazardous waste at cost” (page N-22).

History
Palo Alto’s HHW Program began in 1983 when Palo Alto became the second jurisdiction in the state to provide collection of household hazardous wastes to its residents in response to community concerns about toxic wastes in the environment. The objectives of the HHW Program were to provide a point of contact for educating the public about the safe use, storage, disposal and alternatives to HHW products, and to help reduce the release of HHW to storm drains, landfill and the sanitary sewer. In 1986, the Tanner Bill (AB 2948) was passed requiring counties to establish hazardous waste management plans (Health & Safety Code 25135-25135.9). In 1987, the Greene Bill (SB 477) was passed requiring each City to either adopt a city hazardous waste management plan or incorporate the County’s plan into the City’s plan.
In 1989, AB 939 was passed mandating that cities adopt and submit a HHW Element, a document that sets policies, objectives and programs for collection of HHW in compliance with state mandates. Palo Alto’s Household Hazardous Waste Element (HHWE) (June, 1991) evaluated HHW alternatives and selected the development of a permanent HHW facility to phase out the monthly collection events that were taking place during that time. At the time, since Palo Alto’s program predated the Santa Clara County (SCC) program, and since Palo Alto had a mature well-run HHW program, Palo Alto decided to continue its own program instead of joining the SCC HHW Program.
Initially the HHW Program was operated by volunteer City staff and collection days were infrequent. As the program grew, the collection days increased to four times per year and the City contracted out staffing to a hazardous waste management company. Now collection days are the first Saturday of each month.
In 2008 the HHW Program expanded to include an appointment based program. Residents can now call in and make an appointment for one or more weekday events scheduled mid-month. The appointment program provides a weekday drop off alternative to the monthly Saturday events. Call (650) 496-5904 to find out when the next appointment based event is scheduled.
