What is biogas?
Biogas is a mixture of gases produced as anaerobic bacteria break down organic matter. It is a renewable gaseous fuel containing approximately 50-70% methane and 30-40% carbon dioxide. Biogas is produced as a by product from the decomposition of organic waste in landfills and anaerobic digesters that process agricultural waste and municipal waste water.
Biogas is produced by bacteria through the biodegration of organic material under anaerobic condition. Natural generation of biogas is an important part of biogeochemical carbon cycle. It can be used both in rural and urban areas.
Anaerobic digestion of animal manure and other agricultural waste offers a number of additional benefits to farmers, including reduced air and water pollution, odor management, production of environmentally benign co-products including organic fertilizer and animal bedding material, new revenue streams such as sales of renewable natural gas and more environmentally friendly fertilizers.
