Biogas, which is mainly

methane, is a gas produced

from the digestion of organicmaterials in an oxygen-free

environment (anaerobic

fermentation).

Household waste, especially from backyard

piggeries and poultries, are usually disposed in open-

dug pits which are messy, odorous and often are

breeding grounds for mosquitoes, flies, rats and pathogenic bacteria. This system of waste disposal

threatens the ground water through the infiltration of

pollutants.

This scenario creates health hazards as well aspotentials for conflict with neighbors.

Methane, which is a main component of biogas,

provides cooking fuel for household use as well as energy for

other gas-operated appliances such as: refrigerator, iron, and

lamps. On a large scale, this can even provide power to run

generators and provide electricity.

Energy from Biogas

The digested waste from the system is 90%

pathogen free and very high in nutrients, which are vital forplant growth. As opposed to open composting, nutrients from

the waste are merely broken down into simpler forms and are

not oxidized. This translates to its high value as an organic

fertilizer, soil conditioner and as a biological pesticide.

There are various sizes of household-model biogasdigesters with different gas production potentials and waste

digestion capacity. The table below shows digester sizes

from 4 -10 cu.m. with corresponding gas potential (LPG
