We participate in two types of composting:

Backyard Composting

We use the Earth Machine to compost large food scraps, paper waste and green waste. The Earth Machine is stored outside in our vegetable garden. The end result of this method provides us with a rich soil amendment that we use in our garden and on our houseplants. From this compost we can also create “compost tea” which acts as an organic liquid fertilizer for our plants.

Vermicomposting

We use the Wriggly Wranch worm composting bin to compost small food scraps and smaller amounts of paper waste. The red wiggler worms do all of the work to break down materials placed in the bin. The bin is stored in our garage, but could be stored in the house as it produces little to no smell if the living conditions inside of the bin are optimal. The end result of this method provides us with castings (manure) from the worms that act as a rich soil amendment for our plants; compost tea can also be made from the castings. The worms also produce a highly concentrated liquid by-product that some refer to as “worm poo juice”. If diluted with water, this by-product is used as a natural fertilizer on our plants.

By composting we are able to reduce our waste and provide our garden and houseplants with rich organic nutrients from the composted material.

If you are interested in learning more about these two methods of composting please visit the West Contra Costa Integrated Waste Management Authority website.

If you are a resident of West Contra Costa County, you can purchase The Earth Machine compost bin, the BioStack compost bin, or the Wriggly Wranch worm composting bin at a subsidized cost from the Integrated Resource Recovery Facility (IRRF) located in Richmond. The Authority also offers free composting classes to West County residents.

Alternatively, residents of Alameda County can purchase the Wriggly Wranch or the Smith and Hawken BioStack composting bin at a subsidized cost through StopWaste.org.
