1. Biogas is an Eco-Friendly
Biogas is a renewable, as well as a clean, source of energy. Gas generated through bio-digestion is non-polluting; it actually reduces greenhouse emissions (i.e. reduces the greenhouse effect). No combustion takes place in the process, meaning there is zero emission of greenhouse gasses to the atmosphere; therefore, using gas from waste as a form of energy is actually a great way to combat global warming.
2. Biogas Generation Reduces Soil and Water Pollution
Overflowing landfills don’t only spread foul smells- they also allow toxic liquids to drain into underground water sources. Consequently, yet another advantage of biogas is that biogas generation may improve water quality.
3. Biogas Generation Produces Organic Fertilizer
The by-product of the biogas generation process is enriched organic (digestate), which is a perfect supplement to, or substitute for, chemical fertilizers. The fertilizer discharge from the digester can accelerate plant growth and resilience to diseases, whereas commercial fertilizers contain chemicals that have toxic effects and can cause food poisoning, among other things.
4. It’s A Simple and Low-Cost Technology That Encourages A Circular Economy
THE BIOGAS CYCLE
The technology used to produce biogas is cost effective. It is easy to set up and needs little investment when on a small scale. Small biodigesters can be used right at home, utilizing kitchen waste and animal manure. A household system pays for itself after a while, and the materials used for generation are absolutely free. The gas manifested can be used directly for cooking and generation of electricity. This is what allows the cost of biogas production to be relatively low.
5. Healthy Cooking Alternative For Developing Areas.
Biogas generators save women and children from the daunting task of firewood collection. As a result, more time is left over for cooking and clean. More importantly, cooking on a gas stove, instead of over an open fire, prevents the family from being exposed to smoke in the kitchen. This helps prevent deadly respiratory diseases.
