Does not need a concrete dome that is difficult to build, expensive and prone to leaks.Does not need a floating (metal) cover that corrodes, is expensive and difficult to operate.Does not need a stirring system that corrodes, is laborious and prone to leakage.The HBS has a simple sediment removal process that is easy and convenient to operate.Inoculant preparation: three weeks before construction, place 100L of manure in a 200L drum and mix thoroughly with 50L to 100L of water. Preparing more is better if possible.Upon completion of HBS (all surfaces are fully dried), pour all the innoculant prepared into the HBS.Keep adding manure (thoroughly dissolved in water with 1:1 ratio) into the HBS until the outlet compartment is half full.With biogas outlet valve closed, after a few days, the HBS cover must begin to bulge (indicating it is filling up with gas.Select a location for the HBS close to where the gas will be used. (We recommend collecting manure and bringing it to the HBS for feeding.)Choose a location away from trees whose roots can break the digester walls. (Min area: 2.5 mtr x 3.0 mtr)Dig the ground 2.5m x 2.5m wide and 2.0m deep.Build the footings and reinforced concrete slab.Eventually (sooner if more inoculant was added and later if little or no inoculant was added at the start) biogas will be produced indicated by a fire or flame being lighted.Warning!— The fire or flame produced may be invisible (see picture).Clogging— Run a gas pipe from the HBS to a burner such the pipe is progressively inclined. Biogas contains water vapor that condenses and collects in cavities that will hamper flow.Gas-piping— Use the thicker 3/4" or 1.0" black PE water piping material (available in rolls in most hardware stores) and PE fittings and valves wherever possible.The Philippine Home Biogas System (HBS) shown above was prepared on January 2006.A newer version updated in October 2007 called HBS2is also available. It uses an all-concrete construction so that it can be built anywhere at low cost. Building plans and instructions are provided...Author: Gerardo P.

Baron, an agriculturist at heart decided to move his family straight from the province of Tarlac where his parents and siblings have various agro ventures. Since their business of layer farms is running well, the La Salle-trained engineer- who had worked on GE locomotives while in Canada- decided to get into other agricultural ventures.

When Gerry Baron returned to the Philippines for good after 17 years in North America, our country was not in dire straits, nor was anyone able to predict that the price of crude oil would exceed 60 dollars a barrel.
