Many common household items should never be thrown in your regular trash, because they can be dangerous to you, city workers, and the environment. Some are toxic, like chemicals; some can cause fires, like batteries or aerosol cans; others pose health risks, like old tires; and some may explode, like car batteries.

The way to dispose of these common household chemicals is to use them up before throwing the empty bottle away.

This guide will help Presidio residents understand what items are hazardous, why they are dangerous, and how to safely dispose of them.

Examples of these batteries include:

  • Car batteries (lead-acid)

  • Lithium-ion (phones, laptops, power tools)

  • AA / AAA / button batteries

  • Rechargeable packs



Household chemicals can harm you, sanitation workers, and the environment, and some can produce dangerous gases if mixed. Never pour them down the drain or throw them in the trash.

As we don’t currently have any place to get rid of chemical waste, the best course of action is to use up the chemicals for their intended purpose. In the case of paint, let it dry before disposing of it in the trash.

Otherwise, you can dispose of your tires with Rohana Auto Service for 5$ per tire.
