Recycling Opportunities in Concord

Home Composting Workshop on May 15th

Recycling OpportunityThe City of Concord is hosting a free home composting workshop on Thursday, May 15th from 6:30 to 8:30 p.m. in the City Council Chamber at Civic Center, 1950 Parkside Drive. "Composting yard trimmings and food scraps is easy, great for the yard and garden, kind to the environment and saves money and resources," says workshop instructor Todd Sutton, aka the Waste Sleuth. "Preventing unnecessary waste is an important goal for all of us. Did you know that more the 25 percent of what is in our garbage cans is food scraps? Composting is a great opportunity to divert this material away from the garbage can and into your soil."

Sutton, an expert with more than 22 years in the environmental field, has appeared on national television including Discovery and the History channels, and has educated thousands on waste prevention, reuse, recycling, and composting.

The class is free but registration is required and space is limited. To register, email Concord Senior Planner Joan Ryan at or Register here. For further information regarding the instructor, contact Todd Sutton, aka the Waste Sleuth, (925) 787-8913,;

Residential Recycling

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

All three containers should be wheeled to the curb on the evening before or by 5 a.m. on the day of garbage collection service. All wheeled containers 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 containers without damage to any property.

All grass and yard clippings will be disposed of directly into the wheeled green yard waste container. Please do not place plastic bags into the green waste containers, 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 container, without bagging it. The following items can be recycled as green waste:

Yard Debris Ground clippings
Leaves Tree trimmings
Wood Chips Weeds
Brush House Plants
Hay Straw
Cactus Garden Trimmings
Flower & Flower Cuttings Grass
Shrubbery Pruning
Tree Twigs & Branches 6" or less in diameter & 3ft or less in length

Green Building Guidelines

Conventional home building and remodeling practices consume large quantities of wood, plastic, cardboard, paper, water and other natural resources.

In some cases money can be received for used building materials and construction wastes.

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 & Recycling Guide is available in its entirety.
