Comparing the Types of Compost Methods

You can divide the composting methods into two groups: Passive and Turning.

Passive Systems


Passive Systems tend to cost less and require less work. They are called passive systems because you take a passive role in the compost process, that is, you pretty much don't intervene once the process is set in motion. The trade off is that the rate of composting tends to be fairly slow.

Turning Systems


Turning Systems are designed to accommodate your intervention into the process. Theoretically your intervention, mostly turning the composting materials and maintaining moisture levels, will accelerate the rate of decomposition.

There are two tables for each of the Passive and Turning compost method groups. One of the tables shows which waste types are suitable for the methods that can be employed. The other table gives relative values for:
  • Volume of waste the method is capable of processing
  • Cost of equipment needed to employ the method
  • Work: Physical labor required to keep the system working
  • Complexity: The level of technical knowledge required
  • Space: The amount of space the method requires
