Sufficient cooking fuel, financial freedom?

Wakiso Children School of Hope – located in Bulabakulu Village in Wakiso District. Bulabakulu Village currently has about 350 children with 10 or so adults to care for120 who are residents at the school. Andy Bull  from  Africa Greater Life Mission UK got in touch with Green Heat to design and install a biogas digester for the school.

A 12 m3 biogas digester was proposed, designed and installed to generate gas for at least 40 percent of the school’s cooking needs. The digester is connected to a Green Heat toilet and is fed with human excrement, human urine and  food leftovers. The quantities of available feedstock are sufficient for this digester.

Biogas technology is an integrated waste management system that is a clean, renewable, naturally produced and under-utilised source of energy. The gas produced is composed of 50-70% flammable methane that can be used for cooking purpose. A biogas system provides on-site energy production, storage and access.

The decision taken by Wakiso Children’s school of Hope to install a biogas unit was for both economic and long term environmental reasons. Although the initial investment for the biogas installation was high, the schools expects save approximately over 40 percent of money they would have spent on firewood every year by using biogas for cooking. The money saved from having the biogas unit will be go directly towards improving services at the school.

The environmental benefits of a biogas digester to Wakiso Children’s school of Hope are in the provision of energy, the disposal of organic wastes and the improvement of air quality through reduced concentrations of indoor air pollutants. Also the effluent of the biogas digester is a valuable organic fertilizer.

Finally,  a friend once said, “The more people are self sufficient in cooking fuel, the more personal and financial freedom they have.” – Emma Casson. Watch this space, we will soon tell how much financial savings biogas can contribute to our institutions!

  1. Great news – too many people say it can’t be done with sewage alone which is obviously not true. Can I ask: what happens if you greatly increase feedstock input? E.g. Loads of fish waste from the market? Or bags of sawdust from the carpenter? How do you know when to stop adding new material?

  2. Financial freedom is a word that has taken primacy in the 21st century. It is a term that describes a lifestyle that is organically planned where no one is required to work for income to cover their expenses. Financial freedom perpetuates that one can be free of the responsibilities of money as long as he has set a life defining plan to handle his finances.*
