Our Fixed Dome/Concrete Biogas Plant is a durable and reliable renewable energy solution designed to convert organic waste into clean, usable biogas. The system is constructed using masonry and concrete materials, making it suitable for homes, farms, institutions, and businesses that require a permanent biogas installation.
The fixed-dome design provides a long-term solution for organic waste management and renewable energy generation, with the underground structure offering protection from external environmental conditions and requiring relatively little surface space.
How It Works
The system operates through a simple process:
- Organic waste is fed into the digester
Suitable materials such as livestock manure, kitchen waste, and other biodegradable waste are mixed with water and introduced into the digester. - Anaerobic digestion takes place
Inside the sealed underground digester, microorganisms break down the organic material in the absence of oxygen. - Biogas is produced
The digestion process generates biogas, which accumulates in the dome-shaped gas storage area above the slurry. - Biogas is supplied for use
The gas is directed through a gas pipeline and can be used for cooking, heating, and other suitable applications. - Bio-slurry is produced
The digested material flows out through the outlet chamber and can be collected and used as an organic fertilizer after appropriate handling.
