Environmental Science
More than 2,200 sites in the United States are producing biogas via anaerobic digestion, yet the generated biogas is often flared (burned off) because the economic returns do not justify the required investments to use the biogas for energy. If more research and development were put into enhancing the economic viability of using biogas for energy, which facilities could potentially provide the most even distribution of energy across the country?
- wastewater treatment plants
- livestock operations
- food waste
- landfills
