Let’s Do Our Part!

At Mt. Diablo Resource Recovery, we care about the environment and need your help to divert as much material from going into the landfill.

By utilizing our recycling programs and placing the proper items in each container, you are doing your part in decreasing contamination and reducing greenhouse gas emissions from the landfill.

New Food Waste Recycling Program Coming Soon!

Mt. Diablo Resource Recovery and the cities are working together to put all the pieces in place for this exciting new program.  We will keep all of our customers apprised of that schedule, but as of now, deployment is currently with our commercial customers, with residential and multi-family properties beginning 2023.

Our goal is to make this easy for you!

When in Doubt, Find Out!

Our Recycle Resource Tool helps you get your containers right.

Click on the magnifying glass 🔎
to the right and type in the item, and we will tell you what container to place it in. If we cannot collect an item, we will do our best to point you in the right direction. 

Search tip — Keep material look-up general. For example, rather than searching the number on that plastic item, try entering the item in a generic form such as a soda bottle or milk jug.

Due to the truck being semi-automated, your driver will empty your blue cart, then refill it with the bundled cardboard and use the truck’s arm to lift the contents into the hopper.

E-Waste & Hazardous Waste are Too Toxic for Your Collection Containers.

For the safety of our employees and communities, please do not place batteries, cell phones, laptops, other electronics, or hazardous waste inside your collections containers. 


E-Waste such as TVs, computers, tablets, and cell phones cannot be placed in carts. Retailers such as Best Buy, Apple, and Staples have programs to accept these items for FREE or a small fee.

We can also pick them up from the curbside, with a separate truck, for an additional fee.  

Hazardous Waste

Lithium batteries and other household products with chemicals can contain corrosive, toxic, or ignitable ingredients. Store these items in a safe place until your next city-sponsored event.
