As I always say nature is mysterious and if we protect it properly it will give us more and more benefits. This mother Earth is always kind. Apart from the beautiful nature she has given us, so many resources that is very useful to mankind has changed the destiny of many.
Here today, I am speaking about the natural resources, gold, redstone etc. And all are wonderful gitfs given by this mother Earth. There are many renewable and non-renewable sources in nature, one of the useful and nature friendly renewable resource is the ‘Biogas’.
Biogas is not to be confused with ‘natural’ gas, which is a non-renewable source of power. Biogas is a mixture of gases, primarily consisting of methane, carbon dioxide and hydrogen sulphide, produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste, wastewater, and food waste. It is a renewable energy source.
Biogas is produced by anaerobic digestion with anaerobic organisms or methanogen inside an anaerobic digester, biodigester or a bioreactor. The anaerobic process of decomposition of organic matter has been happening in nature for millions of years, even before fossil fuels, and continues to happen all around us in the natural world. Today’s industrial conversion of organic waste into energy in biogas plants is simply fast-forwarding nature’s ability to recycle its useful resources.
Biogas is primarily methane and carbon dioxide and may have small amounts of hydrogen sulfide, moisture and siloxanes. The gases methane, hydrogen, and carbon monoxide can be combusted or oxidised with oxygen. This energy release allows biogas to be used as a fuel; it can be used in fuel cells and 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.
It’s a highly effective way to recycle residual matter that would otherwise end in landfills, impacting air and water quality and the health and safety of entire communities.
It is an eco-friendly alternative to natural gas and other fossil fuels. It can help reduce greenhouse gas emissions, while also increasing access to clean energy sources for off-grid households in rural areas. Its popularity has been growing not just in developing countries, where it provides communities with cheap energy for heating and cooking, but also worldwide as more governments are looking for alternatives to fossil fuels.
The biological matter that’s used to produce biogas will naturally decay anyway, so capturing the gases produced by this decay, and using them as an energy source, causes less harm to the environment than allowing them to escape into the atmosphere. The process of producing biogas is also largely cyclical and fits into an overall sustainable cycle of managing agricultural waste.
High levels of methane are produced when manure is stored under anaerobic conditions. During storage and when manure has been applied to the land, nitrous oxide is also produced as a byproduct of the denitrification process.
Furthermore, by converting cattle manure into methane biogas instead of letting it decompose, global warming gases could be reduced by 99 million metric tonnes or 4%.
