Biogas technology is a kind of rural energy engineering technology, which aims to deal with livestock manure, crop, food waste, food processing waste and municipal solid waste, so as to realize the agricultural ecological virtuous cycle. It has the characteristics of controlling environment pollution and providing renewable biomass energy to society, highly valued by many countries in the world, especially in the aspect of reducing greenhouse gas emissions for developing countries. It is truly a powerful measure to mitigate the environmental and energy crisis, with a positive impact on agriculture, environment society as well as economy.
Biogas is primarily methane (CH4) and carbon dioxide (CO2) and may have small amounts of hydrogen sulphide (H2S), moisture and siloxanes. The gases methane, hydrogen, and carbon monoxide (CO) 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.
