What are Hazardous Wastes?

Hazardous Wastes are materials that are either flammable, corrosive, highly reactive or poisonous. As such, they should not be put in the trash. Many chemicals used around the home, in our cars, and in manufacturing are hazardous. Expand the list below for specific examples and links to more information.

Electronics also pose a hazard when not disposed of properly. E-waste should never go into the trash or recycling and must be disposed of at specific e-waste collection facilities. Visit our E-waste page for all the details. 

Where can I bring my hazardous waste?

Not all hazardous waste facilities are the same. Some are free to only residents of certain areas, some accept different materials, and most have different hours of operation.

All local hazardous waste collection centers are listed in the “Where to Go” section at the bottom of each material page, but we’ve also included them here (click a specific region to expand the list):

Who can use hazardous waste collection facilities and events?

Hazardous Waste facilities and one-day collection events are designed for residents and small businesses. Businesses should review our Businesses with Hazardous Waste page for more details.

Each event and facility is different, so please review the information carefully. Contact the event or facility operator if you have questions.

Do not bring explosives, biohazards, radioactive materials, needles, or controlled substances to hazardous waste collection sites or events unless specified.

How should I transport my material?

Please make sure that all of your waste is securely contained in your vehicle. Each container should have a properly fitting lid and must be no larger than 5 gallons. Also, it’s best to double-contain your material in cardboard boxes or plastic bins.

Each collection center has its own acceptance limits, so please call ahead to see how much waste you can transport at one time. Residents should never carry more than 15 gallons or 125 pounds of hazardous waste in their vehicle at a time. Customers that are carrying more than what can be accepted at a specific location may be turned away.

This is a great example of what NOT to do. Transporting waste unsecured and in improper containers puts both yourself and the community at risk.
