Anaerobic Digestion is a method where microbes break down the organic wastes when oxygen is not present. The procedure is mainly used for domestic and industrial purposes to produce fuels and manage wastes. It usually occurs in soils, oceanic basin sediments and lake and is used for treating sewage sludge and biodegradable waste. It can lessen emission of the landfill gas into atmosphere. Anaerobic digestion of organic wastes is an important source of energy for food businesses, farms and sewage treatment plants. It is used widely as a renewable source of energy and produces biogas that consist carbon dioxide, methane and some other contaminant gases.
After all generation of biogas in recent years has received great attention in the country of Australia. It is being largely used for electricity generation and heating. In fact a number of projects that have been initiated in Australia want to learn about the issues which need to be considered for improving the reliability of the electrical system. Many of these projects have called for exploring the possibility of generation in biogas in Victoria at the waste water treatment plant as one of their criteria towards producing a final feasibility report.
Biogas projects usually work well where a consistent demand of electricity exists at site where waste is collected or created like food manufacturing plants or livestock farms. Sewage treatment plants may even supplement their power supply and reduce greenhouse emissions via lagoon cover technology and digesters.
