What key shift occurred in anaerobic digestion goals after World War II and specifically during the 1970s?
Answer
From waste disposal to resource recovery
In the decades following World War II, and accelerating during the energy crises of the 1970s, the primary objective of anaerobic digestion underwent a transformation. Initially, the technology was viewed solely as a method for waste volume reduction and odor control. As global energy demands increased, the potential of the captured biogas as a fuel source became a central focus. This shift turned the digester from a necessary waste management cost into an asset, functioning as an on-site power plant that could utilize combined heat and power units to sustain operations and produce energy.
