Ancient Persians observed that rotting vegetables produce flammable gas. In 1859 Indians built the first sewage plant in Bombay. Marco Polo has mentioned the use of covered sewage tanks in China. This is believed to go back to 2,000–3,000 years ago in ancient China. This idea for the manufacturing of gas was brought to the UK in 1895 by producing wood gas from wood and later coal. The resulting biogas was used for gas lighting in street lamps and homes.
Biogas digesters prove that ‘sewage’ does not have to be a dirty word. One of the biggest unsolved public health and environmental problems facing all of us is the untreated or partially treated sewage that is flowing into our rivers, our townships and our ground water.
