the Holistic approach
This fantastic project focuses on two major themes, cost reduction and income generation.
The kitchen, despite being fuel efficient, still burnt hundreds of trees a year in order to provide school meals. This wood was not from sustainable sources and therefore harmful to the environment and increasingly expensive. By providing a biogas system to the school we are able to provide them with a sustainable source of fuel for their cooking.
The biogas system is fed directly from human waste and manually from cow waste. the waste then generates methane which is piped to the kitchen and used for cooking the meals. The bio-slurry that is produced from the overflow tank is then used to enrich the soil in the surrounding area which is used to grow fodder for the cows to eat and vegetables for sale. The milk from the cows and the vegetables are sold and the income used to cover the cost of the farm hands and the profit is used to maintain the schools assets.
The students get to work on the vegetable growing and gain knowledge and experience of different growing techniques that they can take home to their own farms and grow vegetables there.
This project has required the biogas chamber and chow shed with accommodation to be built from scratch and the student toilets to be adjusted to flow directly to the chamber. A wall around the biogas, toilet, cow shed with accommodation and the garden has also had to be constructed to ensure security and protect the land from wandering cows and goats from neighbouring farms. Pipes have been laid to move the gas from the chamber to the kitchen where new gas cookers have been purchased. The kitchen windows have had to be ungraded for security purposes.
Consideration is also being given to the need of a borehole to provide a reliable supply of water for this project.
