2M Cubic Biodigester Price
KSh 130,000.00
The typical price range for a 2 cubic meter biodigester in Kenya is Ksh 130,000 – 150,000. This size is suitable for a medium household, small institution or farm with around 50 users.
Key factors affecting the cost include materials used for construction, whether it’s a prefabricated or custom-built model, and expertise needed for installation.
Concrete biodigesters are generally more expensive, with prices starting from Ksh 150,000. Plastic polyethylene digesters can cost between Ksh 120,000-150,000 for a 2M3 size. Prices also depend on whether it’s a fixed dome, floating drum or tubular/tank model.
Additional costs may be needed for plumbing equipment, skilled masonry, site preparation, gas pipes and appliances.
Operating costs are minimal – mainly feedstock inputs and periodic maintenance. The payback period can be 1-2 years with the waste exhaust savings.
Description
2M3 Biodigester Design
Floating drum and tubular digesters around 2M3 size are commonly used for domestic and small farm applications due to their simple, low-cost designs. Various configuration options are possible based on user needs and site conditions.
The most common designs for a 2 cubic meter biodigester suitable for a medium household or small farm include fixed dome, floating drum and tubular digesters. The fixed dome consists of an underground digester chamber made of brick, concrete or stone masonry with a fixed gas dome.
Floating drum types have a movable gas drum that floats up and down to store and remove biogas. Tubular digesters use a simple plastic or polyethylene tube buried underground.
For a 2M3 biodigester, a floating drum or tubular design is generally preferred as they are easier to construct and have lower capital costs compared to fixed dome types. Typical dimensions are around 1.5-2m diameter and 3-4m length for a cylindrical shape. The inlet and outlet consist of PVC or HDPE pipes connected to the main chamber
