Concord makes Sustainable Choices

The City of Concord is committed to the safety, environment, sustainability, and quality of life of the community.

Residential Recycling

Going GreenEach single-family household in Concord has one blue, 64 gallon wheeled recycling cart; one green, 96 gallon wheeled yard waste cart; and one brown, wheeled garbage cart.  Residents can choose a 96-gallon garbage cart, a 64-gallon garbage cart, or a 32-gallon garbage cart. Weekly collection of additional wheeled recycling carts or green waste carts is available from Concord Disposal for $7.85 per month each.

All three carts should be wheeled to the curb on the evening before or by 5 a.m. on the day of garbage collection service. All wheeled carts should be placed at the curb, three-feet apart from one another - not obstructed by or close to any parked vehicle or any other object. This will allow Concord Disposal's new automated trucks to pick-up and empty the carts without damage to any property.

All grass and yard clippings will be disposed of directly into the wheeled green yard waste cart. Please do not place plastic bags into the green waste carts, as they are not recyclable. No wood, treated lumber, dirt, rocks or pet waste can be recycled as greenwaste. If you have a gardener who mows your lawn, please be sure to advise him/her when the new service begins to place all yard clippings directly into the green cart, without bagging it. Recyclable Items.

Grasscycling is the simple practice of leaving lawn clippings on your lawn. These clippings decompose quickly and release valuable nutrients back into the soil. For more information, including a discount program for purchasing a mulching mower, visit

Green Building Guidelines

Conventional home building and remodeling practices consume large quantities of wood, plastic, cardboard, paper, water and other natural resources. The City of Concord has joined with 18 other Contra Costa cities and the County to develop a comprehensive guide for home remodeling and new construction. View the Green Building Guidelines on line or call the City of Concord at (925) 671-3448 to receive your free copy.

Construction and Demolition Recycling

Construction and demolition, whether for a bathroom remodel or a new shopping center, creates considerable solid waste. There is a list of local alternatives for recycling construction debris (scrap metal, tiles, concrete, porcelain, dry wall, wood, doors, windows, etc.) and much more HERE.

Household Hazardous Waste Recycling

The City of Concord, in cooperation with other Central County cities, funds the Household Hazardous Waste Collection Facility. This facility accepts household hazardous waste from residences for recycling. There is no charge to use this service and no appointment is necessary. The facility is open to residents of Concord and other participating Central County jurisdictions from 9 a.m. to 4 p.m. on Monday, Thursday, Friday and Saturday. Small businesses must make an appointment to use the facility and are charged a nominal fee based on the type and quantity of waste. The facility is located at 4797 Imhoff Place near the intersection of Highway 680 and Highway 4. Call 1-800-646-1431 for more information and detailed driving instructions or visit Examples of household hazardous waste accepted include paint, motor oil, household cleaners, automotive care products, garden care and pest control products, pool chemicals, glues, resins and other materials.

Disposing of Expired and Unwanted Medications

Pharmaceuticals should not be disposed down a toilet or drain. Medications can make their way into our streams, Bay and Delta where they harm wildlife and the environment. Proper disposal prevents abuse and decreases the likelihood of anyone taking a wrong or outdated medication by mistake.

Expired and Unwanted Medications can be dropped off at the City of Concord, Police Department, 1350 Galindo Street, Concord. There is a drop bin in the lobby. Pills should be in a sealed plastic baggie.

More information on Pharmaceutical Disposal Program.

Recycle Used Motor Oil

Concord residents can call Concord Disposal and ask for a free oil collection container. We will deliver one free of charge. When it is full, please contact Concord Disposal Service to schedule a curbside pick up. The City of Concord received a grant from CAL Recycle to fund this curbside oil program. This is only for automotive oil.

Central Contra Costa Sanitary District collects used motor oil at their Household Hazardous Waste collection facility located at 4797 Imhoff Place, Martinez (near the intersection of Highways 680 and 4).

Reduce, Reuse, Repair, and Recycle

We can each have an impact on the amount of garbage produced in our City by becoming aware of how much we throw out and by changing some of our habits about buying and using things. Environmentally-aware consumers produce less waste by practicing the 4Rs: Reduce, Reuse, Repair, and Recycle. They buy products that are less toxic or contain less packaging, use reusable containers and other reusable items, maintain and repair products, participate in recycling programs, and buy products made from recycled materials. Please visit the central Contra Costa County Solid Waste Authority Web site for detailed information on recycling and reuse.

For more information on any of these programs or to express comments and suggestions e-mail The Contra Costa County 2005 Contra Costa Reuse and Recycling Guide is available in its entirety.
