Basics of Anaerobic Digestion
An Introduction to Anaerobic Digesters
A biological process occurs to this mixture to produce methane gas, commonly known as biogas, along with an odor-reduced effluent. Microbes break down manure into biogas and a nutrient-rich effluent.
- Reduced odor, fly eggs, weed seeds in digested manure
- On farm power production sales
- Tipping fees from other feed stocks (food wastes)
- Pathogen reduction of land applied nutrients
- Rural electric grid voltage support
- Reduced methane emissions, a greenhouse gas
- Reduced dependency on foreign fossil fuels
Notes and Lessons Learned:
- Anaerobic digestion "Does Not Reduce Nutrients in Manure"
- If consdering to build an anaerobic digester, select an experienced "Farm Digester" consultant
Some helpful terminology used in anaerobic digestion.
Biogas production systems have many hazardous components and characteristics. No design or project is complete without a safety plan.
