1. Mechanical Composting is the controlled decomposition of organic matter.
2. Rather than allowing Nature to take its slow course, a Composter provides an optimal environment in which decomposers can thrive.
3. To encourage the most active microbes, a compost needs the correct mix of the following ingredients: Carbon, Nitrogen , Oxygen & Water
4. Steps of Mechanical Composting : Crushing , Maceration of waste, Mixing , Ripening , Emptying, Curing & fogging then Composting

Biogas typically refers to a mixture of different gases produced by the breakdown of organic matter in the absence of oxygen. Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste. Biogas is a renewable energy source and in many cases exerts a very small carbon footprint. Biogas can be produced by anaerobic digestion with anaerobic organisms, which digest material inside a closed system, or fermentation of biodegradable materials. Biogas is primarily methane and carbon dioxide and may have small amounts of hydrogen sulphide moisture and siloxanes. The gases methane, hydrogen, and carbon monoxide can be combusted or oxidized with oxygen. This energy release allows biogas to be used as a fuel. It can be used for any heating purpose, such as cooking. It can also be used in a gas engine to convert the energy in the gas into electricity and heat.
