Environmentally friendly biogas can be synthesized using an anaerobic digestion system that is based on the purification of the biogas with some reagents (iron flakes, silica gel, and yeast catalyst). The project design considers four phases namely, the digestion(fermentation) phase, the purification phase, the conservation and the test phase. In the fermentation phase, the decomposition and reaction of micro-organisms take place whereas in the purification stage. consists of three sub-steps, involving a container rich with silica gel, iron chips, and water for the removal of moisture, CO2 and H2S respectively, The conservation stage (the third phase) has an air chamber (tyre tube) for gas storage while the last [hase is the test phase which consists of a Bunsen burner to test the gas stored in the tube.
