Abstract

Biogas is known as a source of renewable energy and it’s made mostly of methane (60-70%) and a mixture of CO2 (carbon dioxide), H2S (hydrogen sulfide), NH3 (ammonia), and SO2 (sulfur dioxide). This gas is produced when biological matter (usually cow manure) is decomposed in an environment without the presence of oxygen with the help of bacteria. It has been popular as a source of energy for over 200 years. In order to generate biogas, the individual has to first build an anaerobic (no oxygen present) digester, or an enclosed tank (usually made of steel), where specific types of organic impurities are placed for bacteria to decompose them. In the environment, it is produced naturally in deep soils, lake bottoms, and wetlands. The dried waste sludge after the production of biogas is reused to produce “EcoFaeBrick“, a quality, easily manufactured, low-cost sustainable building material made from cow dung. The bricks are not only 20% lighter, but they have a compressive strength 20% durable than clay bricks.
