Methane is chemically identical to natural gas, but anaerobic digestion has a much more environmentally friendly lifecycle than fracking and biogas is sustainably produced from liquid wastes. The biogas can be burned directly in a number of commercially available generators and turbines or the methane can be purified and compressed for use in place of compressed natural gas. Anaerobic digestion is a process by which a series of microbes break down organic material into biogas. Hydrolytic bacteria break down incoming material into free fatty acids, amino acids, and sugars; acetogen and acidogen microbes break down this material into acetic acid; and methanogens break down the acetic acid into methane and carbon dioxide.
The household size digester is flat-packed and weighs about 70kgs.
The Flexi Biogas system comprises a flexible reinforced PVC tarpaulin bag as a digester component where anaerobic bacteria act on organic waste.
It sits on the ground and uses plastic pipes for inputs and outputs. Plastic gas pipes tap the gas from the digester and transfer it to the point of use. The digester is covered by a greenhouse tunnel made of ordinary greenhouse material. The high temperature is conducive for Biogas production bacteria action on organic waste.
The greenhouse keeps gas production at optimum levels throughout the year. SimGas has a range of biogas digesters and appliances suitable for households to small enterprises and institutions like schools.
It is quite famous for the PUXIN 6m3 family size biogas digester which is composed of a concrete tank built with a steel mould provided by PUXIN, a glass fibre reinforced plastic gas-holder and a concrete or glass fibre reinforced plastic cover.
The company was founded in in Shenzhen City of China by a doctor in physics who obtained his PhD in Canada and went back to China.
It has distinguished itself as a leader with its expertise and specialisation in the biogas field. Additionally, the company produces a prefabricated mini food waste treatment made of fibre reinforced plastic and collapsible biogas diaphragms.
The kit also includes a single burner biogas stove, and an instructional video for constructing your own biogas plant. With some knowledge of plumbing and you can do the whole thing yourself! Hundreds of people across the world have constructed their own biogas plants from the instructional video and are happily using them.
The picture shows a 1m3 capacity digester for domestic use in rural areas. B-Sustain is located in Chennai, India designing and manufacturing domestic biogas plants starting from 0.
Biogas can be produced from raw material and organic waste like food, market vegetable waste, animal dung, poultry litter, municipal sewage, press mud, and baggase. The unit should be fed daily with solid organic wastes and must be mixed with water in a ratio of 1: In these small domestic biogas units, kitchen waste material mixed with wastewater is fed into the plant through the inlet chamber at the top.
The space required for a domestic plant 1 Cm3 is one square metre. Installation time suggested is about 1- 4 hours, depending upon the model of the plant and the location. The gas generated from the waste of a family of 3 -5 members is sufficient enough to work a single burner stove for more than 2 hrs everyday.
The digester can be installed on an apartment balcony and is completely sealed, so no smell! This biogas kit handles 2kg of ktichen waste that requires pulping prior to feeding the digester. Like most biogas plants they also produce slurry along with Biogas which can be used as a liquid fertilizer on gardens.
The space required for this plant is minimal and it can be installed on a roof-top or anywhere near the house. It is a user-friendly system, and requires only a couple of kg feedstock each day, and disposal of about 5 liters of effluent slurry. These plants are available in 4 types: Located in West Nadakkavu, Calicut the company specializes in portable plug n play type anaerobic digester systems for biogas production from organic solid wastes.
The company has a range of gobar units or biogas kits at various scales. This design innovation means compact biogas units can be installed in remote locations where transport of materials is problematic, for example mountainous regions.
The company also has a range of biogas appliances such as rice cookers, stoves, and water heaters. The company has a range of digestor sizes from 3,L through to 7,L and can supply systems that include electrical gensets.
For instance the 5,L package comes with the digester, one purifying biogas methane purifier MP 12 PVCa gas holder with a capacity of 5 m3, one generator BG w biogas power generators wattsbacterial methane activators GP-7 for 1 month, installation of equipment, and stoves.
Cost for this is Rp. Up until 6 December there have been 10, units built and commissioned across Indonesia.Biogas plants and Bio gas projects - Biotech India: Biogas project consultant in India, Kerala.

One of the main environmental problems of today’s society is the continuously increasing production of organic wastes. The process of anaerobic digestion (AD) of organic matter produces biogas. It mainly consists of methane (%), carbon dioxide and a small amount of mixed gases including hydrogen sulphide.
It is a renewable gas . Who we are. REA Biogas is the trade association for the biogas industry in the UK. Since we have been the unifying force championing the biogas industry, playing a major role in delivering the expansion that we are now seeing.
AQPER took advantage of International Women's Day to announce the launch of the Women and Renewable Energies campaign. For the moment, discover in one click what motivates each of these 36 women to work in the field of renewable energies.
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.
