Biogas
Biomass is one of the key resources employed to harness clean
renewable energy. Waste streams emanating from agriculture,
industrial processes, and municipal waste contributes to the family
of biomass.
Anaerobic Digestion of the organic fraction of biomass takes place
in specially designed anaerobic digesters where microorganisms break
down biodegradable materials in the absence of air/oxygen, resulting
in the liberation of Methane rich biogas. Biogas so produced is a
very potent source of renewable energy & is widely used all over the
world as a fuel to run vehicles & generate power. Generally speaking
there are two temperature ranges in which bio-methanation takes
place - namely, Mesophilic (20-35oC) and Thermophilic (40-55oC).
This process is also categorized as a waste to energy process.
This process also has its
own challenges but, far less than most other processes.
1) Capital costs are marginally higher than other processes.
2) Only biodegradable materials can be processed in this technology.
3) Process technology must be monitored and controlled carefully.
