Enhancing and upgrading biogas and biomethane production in anaerobic digestion: a comprehensive review

Effect of Physical and Chemical Operating Parameters on Anaerobic Digestion of Manure and Biogas Production: A Review

Introduction: The need for food produced from animal husbandry has made it a growing industry which result in increment of livestock waste. On the basis of environmental and economic considerations, these materials require treatment and management. Anaerobic digestion and creation of biogas are the most effective methods of waste management. Several parameters affect the anaerobic digestion of ...

2. Production of Biogas by Anaerobic Digestion

Anaerobic digestion is a natural process in which bacteria convert organic materials into biogas. It occurs in marshes and wetlands, and in the digestive tract of ruminants. The bacteria are also active in landfills where they are the principal process degrading landfilled food wastes and other biomass. Biogas can be collected and used as a potential energy resource. The process occurs in an an...

3. Upgrading Dairy Biogas to Biomethane and Other Fuels

Dairy biogas can be combusted to generate electricity and/or heat. This report, however, focuses on alternate uses of biogas including the upgrading of biogas to biomethane, a product equivalent to natural gas or other higher-grade fuels. Biomethane, which typically contains more than 95% CH (with the remainder as CO 4 2), has no technical barrier to being used interchangeably with natural gas,...

Pretreatment Methods in Anaerobic Digestion for Biogas Generation: A Review

Biogas energy has got importance in the field of energy engineering because of its attractive features. Biogas is produced from different types of waste materials by the process of Anaerobic Digestion. This paper gives the insight of Anaerobic Digestion process and different pretreatment methods used in various experimental research works. Flower waste is also a potential source of biogas energ...
