Trash & Recycling


Many products found in your home are potentially hazardous substances. Because of their chemical nature, they can poison, corrode, explode, or ignite easily when handled improperly. When discarded, they are considered household hazardous waste. Since they may threaten human health or the environment when inappropriately disposed of, household hazardous wastes are not exempt from California hazardous waste laws.

It is illegal to dispose of household hazardous waste in the trash, down storm drains, or onto the ground. Dispose of all Hazardous Waste at Paso Robles Landfill located on Highway 46 East. Hazardous waste can be dropped of at Paso Robles Landfill on Saturdays from 11am - 3pm. with the exception of holidays and rainy days.

It is open to all residents of San Luis Obispo County free of charge (up to 15 gallons or 125 pounds). Small businesses must first call 805-782-8530.

Types of Wastes Not Accepted
Explosives (ammunitions), compressed gas cylinders (>20 gallons), radioactive waste, contaminated soil.

Quantity of Waste Allowed
No more than 15 gallons or 125 pounds total per trip.

Small Businesses
If you are a conditionally exempt small business and generate less than 27 gallons or 220 pounds of hazardous waste per month, the IWMA can provide hazardous waste collection and disposal service for you. 
Call 805-782-8530 for more information.  For other opportunities for businesses, visit the IWMA Business Programs page.

Why Are They Hazardous?

Household hazardous wastes are considered hazardous because they fit into one or more of the following categories:

  • Toxic: Poisonous or lethal when ingested, touched, or inhaled—even in small quantities.
  • Flammable: Ignites easily.
  • Corrosive: Eats away materials and living tissue by chemical action.
  • Reactive: Creates an explosion or produces deadly vapors (e.g., bleach mixed with ammonia-based cleaners).

Before buying a product, read the label. Signal words can serve as a guide to the purchases you make. With pesticides, DANGER means highly toxic, WARNING means moderately toxic, and CAUTION means slightly toxic. With household products, POISON means highly toxic, DANGER means extremely flammable or corrosive or highly toxic, WARNING or CAUTION means less toxic.

What Problems Can Occur?

Improper handling or disposal of products containing hazardous ingredients can result in serious accidents to people and animals, who can be seriously harmed by drinking, eating, touching, or breathing household hazardous wastes.

  • Refuse workers and landfill workers can be injured by chemical splashes or poisonous fumes caused by mixed or concentrated household hazardous wastes.
  • Firefighters can be injured by these household hazardous wastes when responding to a fire.
  • The environment can be seriously damaged when groundwater used for drinking or irrigation is contaminated with household hazardous waste products that have been poured onto or have seeped into the ground.
  • Bacteria needed to break down sewer and septic tank wastes can be destroyed by untreated household hazardous wastes.

Avoiding Accidents

Never leave household hazardous products or wastes within reach of children or pets. When possible, buy products with less harmful ingredients (read the labels). When using a product, read and follow the label directions, never mix it with other products, and use it up entirely. Do not dispose of household hazardous wastes in the trash, on the ground, or in storm or sewer drains. Do not remove product labels, and do not remove products from their original containers.

Proper Management of Household Hazardous Waste

Reduce by purchasing only the amount you need.
Reuse the products by donating unused portions to friends or community organizations.
Recycle leftover household hazardous products that are recyclable and dispose of the others safely by taking them to the Household Hazardous Waste Collection Facility.
