Biogas are produces in digesters and made from
organic sources such as poultry dropping, pig and cattle droppings, water
hyacinths and a host of others. Biogas plays an important role in farming and our environment as a whole as it reduces
health risks, control of pollution and at the same time adds value to the
livestock excreta through it use in production of biogas and improved nutrient
status of the effluent as fertilizer for fish ponds and crop land.
BIODIGESTERS
Biodigesters are used in production of biogas. Biodigesters convert organic wastes,
mainly manure, into a nutrient rich liquid fertilizer and biogas (methane), a
renewal source of electrical and heat energy. In addition to providing fuel, it
offers an environmentally friendly way of treating waste. As waste is processed
in a biodigester, it is sterilized by methane-producing bacteria and the
high-methane environment; over 90% of protozoa, cysts and disease-causing
bacteria, such as E. coli, are killed. The effluent that remains after gas
production is a high quality organic fertilizer that can be safely used on food
crops. Liquid fertilizer has a higher nutritional value than feedstock
initially put in. Quality of crops improves dramatically after one year of
using biodigester fertilizer. A biodigester is normally made out of concrete,
metal or any other material that permits the anaerobic fermentation of organic
materials.
ADVANTAGES
OF THIS TECHNOLOGY
• Provide clean and renewal energy.
Families use less firewood, decreasing deforestation, save money and have
accessible fuel
• Reduce greenhouse gas emission.
The combustion of biogas produces lower greenhouse gas emission than typical
methane emission from a waste
• Reduce contamination of surface
water, groundwater and other resources
• Reduce odours and pathogens
• Convert waste into high quality
organic fertilizer. Families can obtain improved crop yields and save money
Lot of farmers in Uganda, Rwanda, India, Benin
have uses the biogas technology effectively. And others can take a clue from
it.
