Describe Biogas plant with diagram.
Show Hint
A biogas plant converts organic waste into methane-rich gas through anaerobic digestion for cooking and energy.
Solution and Explanation
A biogas plant is a system that converts organic waste such as animal dung, plant material, and kitchen waste into biogas through anaerobic digestion. The biogas produced is primarily composed of methane (CH4) and carbon dioxide (CO2), which can be used for cooking and electricity generation.
Components of a Biogas Plant:
- Inlet Tank: Organic waste is mixed with water and fed into the digester.
- Digester: A sealed chamber where anaerobic bacteria break down the waste to produce biogas.
- Gas Holder: Collects the biogas generated during decomposition.
- Outlet Tank: The remaining slurry is removed and used as manure.
Advantages of Biogas:
- Provides a renewable and eco-friendly energy source.
- Reduces dependence on fossil fuels.
- Produces nutrient-rich organic fertilizer.
