| Anaerobic Digestion Process |
|
|
Anaerobic digestion is the bacterial decomposition of organic matter that occurs in the absence of oxygen.
Anaerobic bacteria exist naturally at the bottom of ponds, swamps and other moist and airless places.
Anaerobic bacteria are among the oldest life forms on earth.
Thousands of years ago, anaerobic decomposition of organic matter produced the earth's coal and oil deposits and created the natural gas we currently use for cooking and heating. The same process can be duplicated today with a mechanical digester that reproduces the ideal natural conditions for decomposition.
Anaerobic digestion differs from composting, which is an aerobic, or oxygen consuming, process. Composting organisms produce the high temperatures the process requires by metabolizing oxygen. Their efficiency is maintained by providing the proper mix of air and organic matter types.
Creating a thriving anaerobic environment, however, only requires maintaining a consistent temperature and organic matter quality within a sealed and oxygen depleted container.
