Early planning now will prevent permitting delays later, as well as saving you time and money. The following are questions to consider:

What type of C&D debris will be generated on-site (wood, metal, cardboard, concrete, etc)?

Identifying C&D debris by material type will help you stage the materials at the job-site and allow you to choose appropriate recycling facilities or service level needed.

How much C&D debris will be generated?

Estimating the quantity of C&D debris that will be generated will help you determine space requirements on the job-site and plan how frequently C&D debris will need to be removed.

Will you be hauling the C&D debris yourself or contracting with Republic Services?

Republic Services (formerly Allied Waste) is the only authorized hauler for the City of Antioch. If you are planning to hire someone to haul your recyclables or garbage, you must use them. Please call to set up recycling and garbage collection service at 925-685-4711.

If you will be hauling your C&D debris to a salvage or recycling facility, call ahead to check hours of operation, disposal fees, and confirm that the facility can receive and recycle your materials.

Will you be using sub-contractors?

Inform your sub-contractors about your recycling requirements. You are responsible for any materials they take away from the job-site. They must take materials to a recognized recycling facility and provide you with recycling receipts. That?s your recycling credit driving away in their truck!

Will the C&D debris coming from the job be separated by material type or mixed together?

The manner in which you collect and sort the C&D debris will determine what facility you can use for recycling. Separated loads of clean materials can be taken to one of the many area facilities listed in your Builder?s Guide. Mixed loads can be taken to facilities listed in the Builder?s Guide that state they can receive mixed materials for recycling. You must insist that the facility provide you with a recycling receipt and you should call ahead to confirm this. A weight tag that simply says ?C&D debris? is not adequate.

If you reusing material at a site that doesn?t have weight tags download a copy of Recycling Receipt For Material(s) Received

The following are examples of receipts and how to read them:
