Risk Factors of Biogas Technology
The risks associated with biogas technology are as follows which should be taken
care while working for biogas production unit:
1. Leakage in the storage tank and/or in the biogas distribution network
2. Formation of flammable mixtures during the digester maintenance operations
3. Accidental release of H 2 S and effluent discharge
4. Overflow of sewage systems or stormwater control due to exceptional
downpours, presence of dangerous products in the raw material used to produce
biogas, overflow, freezing of valves, and high pressure inside the digester

Conclusion
Biogas is a potential green energy resource that can be produced from organic waste
material as a feedstock. Biogas production process is simple, clean, and easy. Biogas
production utilizes agricultural biomass, thereby reducing greenhouse gas emission
due to unsuitable dumping of organic wastes. It also improves energy safety and
decreases fossil fuel depletion. Biomass energy will progressively substitute fossil
fuel, and the community can even rely on biogas energy for satisfying local needs
especially in rural areas; full-fledged utilization of biogas for energy generation
should be explored and needs concentrated efforts, and this technology has found
its utility in domestic, farming, and small-scale industries. Presently reduced efficiency of biogas production plants can be overcome by utilization of modern
technologies to enhance microbial activity within the biogas production units to
get efficient yield of the energy supply. Policy and government producer should have
sympathetic strategies such as subsidization of biogas plan to maintain the growth of
technology in the remotest places. Additional research must be done on superior
bioreactor plan and feedstock presentation improvement to get better costeffectiveness of anaerobic digestion process.
