Biogas Technology

The global demand for energy is met mainly by fossil fuels. Their excessive and indiscriminate use, coupled with increasing demand for energy, will soon deplete their existing reserves. Therefore, it is extremely important to find alternative, environment-friendly, and ecologically sound sources of energy for meeting the present and future energy requirements. Biogas Technology: towards sustainable development makes an attempt to explore the potential of utilizing biodegradable biomass as fuel and manure.

Key Features:

• Discusses the biomethanation process in detail.
• Highlights the utility of biogas as a renewable source of energy.
• Explains the evolution, scope, and potential of biogas technology.
• Depicts popular biogas plant models.
• Provides useful information on carbon credit and highlights the environmental implications of the biomethanation process.
• Presents a knowledge base to biologists, academicians, farmers, and agricultural scientists, who will gain in terms of understanding the basic concepts and applications of the biomethanation technology.
• Provides information on installing biogas plants for meeting energy and manure demands.
