Challenges When Planning an Anaerobic Digestion SystemWhen planning to build an anaerobic digestion system, there are many factors and considerations before you begin.

The following are some of the things you need to have planned out before hand when you are considering to build an Anaerobic Digestion System.

Factors and Considerations When Building an Anaerobic Digestion System


Obtaining insurance: Insurance companies may approach these systems with uncertainty – work with a known manufacturer or installer with proven designs. sets standards and processes for properly managing the biogas when it is utilized.

Obtaining a building permit: Digesters are not common to the rural landscape, so obtaining necessary building permits may involve delays, including the need for possible zoning changes. Allow adequate time to address these issues.

Obtaining permission to accept materials: A new anaerobic digestion system that accepts off-farm material may need to receive a Certificate of Approval under the Environmental Protection Act or an approved Nutrient Management Strategy under the Nutrient Management Act. Allow sufficient time for those processes as well.

Obtaining agreements to utilize energy produced: Information below discusses options to utilize the energy. Building the facility adequate distances from conflicting uses: An anaerobic digestion system is totally enclosed, and the produced biogas is typically contained, stored and utilized. However, there may be some slight odors from feedstocks and other sources. These odors may be more evident if the biogas system is constructed in an area not used to livestock production.

Because the anaerobic digestion system reduces the odor in the effluent, the net effect for livestock facilities is anticipated to be a reduction in odor. Anaerobic digestion facilities have been built in the U.S. for the prime reason of effective odor reduction.
