Fixed-Dome Digesters
AT GUILLERMO AND SANTOS FARMS
In 2009, GMI found that the swine sector had
great potential for reducing methane emissions in the Philippines.
So it organized a training in 2010
To teach participants
About fixed-dome digesters
Which receive livestock manure from farms
Break it down to create biogas
And enable productive use of methane.
They are small-scale and low-cost
Reduce methane emissions at the household/community level
Capture methane for cooking, lighting, and heating
And create useful byproducts such as fertilizer.
GMI trainees installed fixed-dome digesters
At two farms in the Nueva Ecija Province.

Guillermo Farm Digester
Santos Farm Digester
The Guillermo and Santos digesters were built using ferrocement
An alternative construction technology
That is more crack-resistant than conventional concrete

And much cheaper!

How do the Guillermo and Santos fixed-dome digesters work?
The farms collect pig waste
That travels down a conveyance
To the entrance of the digester
Where it breaks down and is converted into biogas.
The Guillermo and Santos digesters produced biogas for cooling pig pens, cooking, and lighting
Reduced odors from livestock manure
And produced fertilizer for crops.
