I was first introduced to biogas technology in 1989 when I joined the Ministry of Energy/GIZ biogas development programme. After extensive research, the GIZ opted to promote and disseminate the floating drum plant in Kenya.  In reaching this decision, consideration was paid to the maturity of the design, the socio-economic status of the rural inhabitants, the local technical expertise and the availability of the construction materials amongst other reasons. In 2007/2008 I had the opportunity of developing a biogas syllabus and teaching biogas plant construction and maintenance while at the University of Nairobi. My current project with AfriCLP actualizes one of my long held visions of adding value to the biogas dissemination programs in Kenya (and East Africa in general) by introducing vermitechnology into each biogas project. Vermitechnology offers the rural farmer an opportunity to maximise the benefits of having a biogas plant by converting the effluent from the biogas digester (also known as bio slurry) into a bio compost that is rich in readily absorbable plant nutrients. Vermitechnology makes use of the metabolism of a species of red earthworm known as Eisenia Foetida, that ingest a variety of domestic and agricultural  waste materials and produce a rich vermicompost as a by product. In effect the rural homeowner benefits from production of the combustible biogas, and the production of a high quality organic fertilizer.
