Composting

NEW – Changes to Composting Guidelines Effective April 1, 2023

Starting April 1, 2023, only food scraps and yard waste will be accepted for composting by the region’s compost processor. The green, compostable waste bags will only be accepted if they are 3-gallons or smaller. More details will be posted here as they are finalized. The compost processor is making the change in order to try and eliminate micro- and macro-plastics from the final compost product.

Benefits of Composting

Almost 20 percent of the waste stream in Boulder County is plant trimmings and fruit and vegetable scraps that could be recycled as compost. Composting is a natural process of decomposition that creates a high-quality soil amendment and can extend the life of our landfills.

  • Nature’s ultimate recycling system where living or once-living materials break down into a rich soil-amendment called compost. Compost is a dark, crumbly, and an earthy-smelling form of decomposed organic matter.
  • Natural Process. Collecting organic materials and combining them to encourage their breakdown makes use of the natural process of decomposition to create a high-quality soil amendment.
  • Saves Money. Composting can be easier and cheaper than bagging organic wastes and having them removed. Your water bills may drop too, since a soil that’s well-amended with compost holds moisture better and reduces run-off.
  • Reduces Waste. Almost 20 percent of the waste stream in Boulder County is plant trimmings and fruit and vegetable scraps that could be recycled as home compost. Recycling organic resources extends the life of our landfills.
  • Valuable Soil Amendment. It is more cost-effective to keep materials on site and cycle them back into the yard as a rich soil amendment – compost.
  • Healthy Garden. Your garden will benefit as well. As the health of your soil improves so will the health of your plants.
