To create an ideal environment for this digestion to take place to make biogas, a few key ingredients are needed: thousands of animals packed in concentrated animal feeding operations (CAFOs), billions of pounds of their waste accumulating, massive manure lagoons, and tarps or domes to trap the gas emitted from the excrement lagoons.
The emissions from the lagoons, consisting mainly of methane and carbon dioxide, can be captured, creating what is sometimes called “biomethane” or “compost gas” which can be used to generate electricity. Factory farm producers can be granted tax credits based on the biogas generated and collect revenue.
Biogas production is a popular scheme among mega-farms that
capitalizes on the waste produced by farmed animals touted as
renewable energy, but it’s perpetuating animal suffering and posing
serious environmental hazards.
Animal agriculture is a leading cause of the climate crisis,
generating about 20% of global greenhouse gas (GHG) emissions
leading to enormous amounts of animal cruelty and environmental
degradation. Researchers continue to back this climate science with
a recent study by Stanford University and the University of
California, Berkeley, exploring the effects of a global phase-out of
animal agriculture on the environment, yielding results showing the
damning reality of animal-ag. If, over a 15-year span, animal
agriculture was eliminated worldwide, carbon dioxide emissions would
be reduced by 68% through the year 2100, according to a Stanford
News blog.
