Anaerobic digestion is a process through which bacteria break down organic matter—such as animal manure, wastewater biosolids, and food wastes—in the absence of oxygen.
Anaerobic digestion for biogas production takes place in a sealed vessel called a reactor, which is designed and constructed in various shapes and sizes specific to the site and feedstock conditions learn more about AD system design and technology. These reactors contain complex microbial communities that break down or digest the waste and produce resultant biogas and digestate the solid and liquid material end-products of the AD process which is discharged from the digester.
Multiple organic materials can be combined in one digester, a practice called co-digestion. Co-digested materials include manure; food waste i. Co-digestion can increase biogas production from low-yielding or difficult-to-digest organic waste. But do you know what it is, and how long it takes to produce?
No worries if you don't! We have put together some information about biogas to help you out but, if you would like to know more, give Inoplex a call on and we would be happy to discuss further. Biogas is created through the digestion of organic matter, otherwise known as biomass, by microorganisms in an oxygen-free environment.
This method is also called anaerobic digestion and can occur naturally anywhere, including the digestive system and effluent ponds, andis artificially created in engineered containers called digesters. The length of time it takes to produce biogas really depends on the feedstock raw material that is used. Anaerobic digestion is a series of biological processes in which microorganisms break down biodegradable material in the absence of oxygen.
One of the end products is biogas, which is combusted to generate electricity and heat, or can be processed into renewable natural gas and transportation fuels. A range of anaerobic digestion technologies are converting livestock manure, municipal wastewater solids, food waste, high strength industrial wastewater and residuals, fats, oils and grease FOG , and various other organic waste streams into biogas, 24 hours a day, 7 days a week.
Separated digested solids can be composted, utilized for dairy bedding, directly applied to cropland or converted into other products. Nutrients in the liquid stream are used in agriculture as fertilizer. The digestion process begins with bacterial hydrolysis of the input materials in order to break down insoluble organic polymers such as carbohydrates and make them available for other bacteria. Acidogenic bacteria then convert the sugars and amino acids into carbon dioxide, hydrogen, ammonia, and organic acids.

Biogas is a renewable energy source that can be used in a variety of ways. Communities and businesses across the country use biogas to:.
Biogas is often cleaned to remove carbon dioxide, water vapor and other trace contaminants. Removing these compounds from biogas increases the energy value of the biogas.
