biogas

What is biogas ?

Biogas is produced through the anaerobic digestion (fermentation) of decaying plant or animal matter. It is the naturally occurring emission of bacteria that thrive without oxygen, and occurs in three steps. First is the decomposition, or hydrolysis, of the biodegradable material into molecules such as sugars. Next, these molecules are converted into acids. Lastly, the acids are converted into biogas. Anaerobic digesters harness the bacteria's natural processes to capture and utilize the biogas, all in a safe, controlled environment.
Biogas produced in anaerobic digesters is burned to generate clean, renewable energy. The main components of biogas are carbon dioxide (30 – 40 %) and methane (60 – 70 %), which, if released in uncombusted form, is harmful to the environment as a particularly potent greenhouse gas. Anaerobic digestion helps manage two of the biggest sources of manmade
methane: livestock manure and landfills. Livestock manure, since it is the main ingredient for the digesters, and landfills, since food waste can be digested rather than dumped. Certainly, methane can be extracted from landfills, but anaerobic digestion is far more efficient for the same waste source.

This is what Businessman and Broiler Farm Owner/Operator Paterno Orola of Silay City has entured as his pet project in doing his share of producing renewable energy in is farm, it s a 2 hectare farm which is located in Brgy Bagtic, Silay City, approximately 2 kilometers Fast of the New Bacolod-Silay Airport. The farm has been operating for 5 years now. The primary product of Mr. Orola's farm is the 45 days old chicken. But just this September 2007, Mr. Orola decided to venture into BIOGAS production for his consumption in his farm. With his own design and creativity he finished his BIOGAS facility 3rd week of October. Currently his facility houses 10 piglets in which their manure will be used as main ingredient in the production of the biogas. Mr. Orola is also looking in the posibility of using chicken manure as one of the ingredient in producing biogas, since chicken manure abounds in his farm.

The septic tank measuring 4ftx6ftx5ft, which the manure goes directly into is located just beside the pigpen. According to Mr. Orola, he is planning to expand this project if the outcome is viable and good in his first trial. He is also hoping that other farm owners with animal livestocks would also venture in this kind of project so that they could also promote the production and unlimited use of clean and renewable energy.
