Economics of Anaerobic Digesters for Processing Animal Manure

Digesters are of interest with regards to climate change, energy, air quality, and water quality. However, digesters are capital-intensive and difficult to maintain. Profitability of a farm-based digester usually requires utilizing the energy, carbon credits, tipping fees, and marketing other co-products such as manure solids that are separated out and composted.

Terminology and Types of Digesters

Anaerobic digestion is the process in which microbes in the absence of oxygen convert volatile acids in livestock manure into …
