Industrial Methanogenesis: Biomethane Production from Organic Wastes for Energy Supplementation

There is a limited availability of fossil fuels on earth, which is depleting at a faster pace with growing energy demands worldwide. Moreover, the burning of fossil fuels releases toxic gases which are harmful for all living beings and increase the earth’s temperature by global warming. Therefore, there is a need to look for other alternative renewable energy sources which can play a major role in mitigating energy needs. The gaseous biofuel derived from biomass, like methane and hydrogen, is considered to be renewable energy carriers, as there is abundant biomass available on earth. Although the production of methane from biological route is old, there are few considerations which need to be addressed like economical feasibility, feed supply and improvement in production capabilities. The report deals with major issues involved with methane production from organic wastes, methanogens and their diversity, production efficiency and sustainability in the near future.
