- Margaret Odwar is a dairy farmer
- She set up a biogas plant at her farm
- She now generates power for her household's use
A Ugandan dairy farmer is able to save herself electricity costs after she set up a biogas plant at her farm to generate power.
Margaret Odwar, who farms in Gulu, started dairy farming in 1997 but was only introduced to biogas technology in 2011.
Speaking to Daily Monitor, Odwar said she previously experienced frequent power blackouts and had to pay high electricity bills.
However, this changed when she began operating a biogas plant fueled by animal waste. She built a dome-like semi-permanent structure that had a digester about six feet under the ground.
She ensures that animal waste is streamed into the oxygen-free digester, which then generates gases such as methane, carbon dioxide, hydrogen and hydrogen sulphate.
The biogas is then stored in a gas tank above the digester. From here, she can use the energy to power her home and farm activities.
Odwar said: “The power generated from my biogas plant is sufficient to run the farm and my home.” In addition, she sells the leftover slurry to other farmers for additional income.
