Earth Machine Compost Bin

Composting bins are now available featuring the earth machine. Contact the Recycling and Refuse Department to buy an earth machine. The cost is $25.00 and quantities are limited.


Using an Earth Machine


Follow these simple steps to successfully compost:
  1. Add high carbon and high nitrogen materials.
  2. Mix or layer materials. After every 12 inches or so, add a few shovel fulls of rich soil or compost.
  3. Keep it damp and aerated. Wait a few months, and voila...black gold!
