Organic Compounds Breaking Down into Biogas

The process of producing methane from manure is fairly straight forward – seal manure in an airtight container at a favorable temperature and it will break down into biogas: a mixture of Methane (CH4), Carbon dioxide (CO2), and trace amounts of other gases.…

Introduction to Biogas and Anaerobic Digestion

Harnessing energy from livestock waste.

Intro | Feedstocks | Processing | Utilization

On-farm biogas production has long been a topic of interest for farmers, with historical records of biogas production going back several hundreds of years. In modern livestock production systems, for example, the benefits of producing biogas are significant and include:

  • provision of supplemental renewable energy
  • odor reduction
  • reduction of emissions of greenhouse gases
  • pathogen control
  • waste biostabilization
  • nutrients are preserved and transformed into plant-available forms

The economics of biogas production, however, are sometimes difficult to justify unless the accompanying environmental benefits and other by-products are considered.…
