Problematic garbage and waste along with the increase of population requires proper management, one for the type of organic waste decomposed ( decomposition) through the fermentation process into gas and organic fertilizer.

Airtight process, without oxygen, will produce bio-gas in the form of CO2 and methane ( CH4) , which is best used as fuel or converted heat as electrical energy. Biogas is a bio-gas, is produced by anaerobic activity or fermentation of organic materials including: human waste ( feces / stool) and animals ( kohe) , domestic waste ( households) , easily biodegradable waste ( biodegradable) or any organic waste easy to decompose ( biodegradable) in airtight conditions without oxygen ( anaerobic) .

The main content of the biogas is methane ( CH4) and carbon dioxide ( CO2) and a little H2S, N2, H2 and O2.

Meanwhile, solid and liquid material after the fermentation process will be an organic compost fertilizer for land improvement and growth of microbial environment around the plant.

The benefits of waste management through a process of anaerobic or biogas are:

• reducing the use of other fuels ( kerosene, wood, etc.) by the household or community,

• generate residual sludge biogas energy generation process as a liquid and solid organic fertilizer as a byproduct of high-quality,

• be a good method of processing waste, have economic incentives, and reduce waste disposal to the environment ( water flow / river) ,

• improve air quality by reducing smoke and the number karbodioksida resulting from the burning fuel oil / wood,

• relatively low cost in installation and become a profitable investment in the long term

• reducing the use of other fuels ( kerosene, wood, etc.) by the household or community

• produce high quality organic fertilizer as a byproduct,

Biogas as a result of a process of fermentation of different organic materials ( all materials derived from living things) is a new renewable energy sources ( renuwable energy) that can be obtained at minimal cost.

Biogas as a result of a process of fermentation of different organic materials ( all materials derived from living things) is a new renewable energy sources ( renuwable energy) that can be obtained at minimal cost. The gas formed in the tube-tight ( without oxygen) Biogas Digester BD 5000L strong, made of fiber glass resin eternally 2504, this type of mat Wr 200 ( woven mat) and mat 300 ( random) , the thickness of 3-5 mm, is able to provide conditions of temperature 30 degrees centigrade, the fermentation capacity of 5 m3 per cycle with a pressure of 5 kg / cm2. Trash and other organic materials can be continuously added to the holes ( intake chamber) , and will be parsed by anaerobic bacteria Phoskko Green ( GP-7) , only 5 days have started to release methane gas ( CH4) and stored at the top of the tube ( gas holder .) Capacity 5 m3 of material inputs plus 2 m3 of gas holders or the overall capacity of 7 m3 and a PLT ( diameter 200 cm, height 390 cm) , will last up to 10 years to 20 years. Produced by biodegradable ( complete knock down) so easily removed, repaired when there is damage or displacement and mobilization costs are cheap, with the installation of gas pipes, stove manufacturer standards and supporting equipment for the utilization of methane gas as fuel specially modified generators are environmentally friendly.
