Abstract :

Biogas technology is a bio waste management tool that promotes the recovery and use of biogas as energy by adapting manure management practices to collect biogas. The biogas can be used as a fuel source to generate electricity for on-farm use or for sale to the electrical grid, or for heating or cooling needs. The biologically stabilized bio-products of anaerobic digestion can be used as a crop fertilizers, beddings and as aquaculture supplements. This research was done to solve the problem caused by bio-waste (pollution and global warming problems) and to produce the low cost gas, which will be used as a source of energy. This was achieved by accessing the availability of bio-waste then designing and constructing a biogas digester which will use raw waste to produce methane gas. Information on the characteristics of different waste was gathered and calculations were used to find the yield of methane from each type of waste. The type of construction material was also considered as it should suite the types of bio-wastes and the chemical reactions in the digester. The research were done in Gaborone and the surrounding rural areas and it is concluded that a family needs about 10 m3 of methane for daily family use, which needs about 17 m3 of digester.
