The Process Behind Composting

Composting can be done simply in your backyard; however, this process describes the ones used by copsting facilities

  1. Collection: Cities and households collect and put out their organic and yard waste. Drivers will pickup and transport the waste to the facility.

  2. Sorting: There are two steps to sorting. First is ridding of any contaminants that have made its way in. Next, is sorting between carbon-rich and nitrogen-rich materials.

  3. Grinding: After sorted, the waste is shredded into smaller pieces. Decomposition accelerates faster the smaller the organic waste is.

  4. Pile Formation: Organic matter is placed in long rows called windrows. Forming windrows allows oxygen to flow through the piles allowing for decomposition.

  5. Decomposition: Decomposition actively begins at this step.

  6. Turning & Monitoring: As organ matter decomposes, piles are turned to optimize airflow and control temperature and moisture.

  7. Curing: Once matter has decomposed, compost is then cured. The curing phase stabilizes and matures the compost. This process can take several weeks to complete.

  8. Screening: The finished compost is screened to remove any unwanted particles. The result of the screening is a fine, fresh soil product.

  9. Distribution: The final product is distributed across California. The soil may end up in gardens, landscaping projects, but most likely is being distributed to farmers.
