BPP as a source of Renewable Energy

Enerzea Power Solution Pvt Ltd (EPSPL) provides solutions with high rate Biomethanation process technology, that helps in capturing methane from a feedstock of green biomass, poultry-litter, cow-dung and other biodegradable sources

The biogas thus produced is 55-60% methane and 45-40% CO2 and is used to generate power.

Biogas reduces global Green House Gas emissions:

• The methane that would have otherwise escaped into the atmosphere due to decay of the organic feedstock is now captured and burnt to produce power.

• Biomass replaces the use of conventional fossil fuels that would have

added to the concentration of CO2 in the atmosphere.

EPSPL provides a complete Turnkey/EPC solution to project developers to set up Biomethanation power plants.


Biomethanation Technology Biomethanation is the process of producing biogas from organic wastes using

Anaerobic Digestion. There are two types of Anaerobic Digestion process:

Design Uniqueness of Digester Our Digesters are designed for high rate digestion and operate in a

Mesophilic range with an optimum residence time of 20-24 days.

The digesters are continuously stirred (mechanical mixing) tank reactors with submersible impellers (single or multiple mixers) specially designed on the principles of non-Newtonian Rheology.

Enhanced agitation and mixing is achieved by recirculation of slurry back

into the digester using positive displacement pumps.

Efficient mixing technology forms the basis of a high-rate and high-yield digestion process.

High-Rate digestion is characterized by higher loading rates of volatile solids per m3 of the digester per day, a shorter retention time and a reduced size of the digester and hence lower project cost (digester cost being a prime cost component of the plant)


Advantages of Efficient Mixing in Digester

Providing good contact between active biomass and input feed.

Minimizes foaming Providing physical, and formation of a chemical and

scum layer and biological uniformity deposition of solids. within the digester.

Preventing pH and temperature gradient Distributing the organics

and hence higher and diluting the efficiency of conversion inhibitory substances of organics to methane within the digester.

Benefits of Digester Residue ( Biofertilizer)

Contains micro and macronutrients, such as Nitrogen, Phosphorus and Potassium and a fair amount of Manganese, Zinc, Copper and Iron which increases the microbial activity.

Carbon as an energy source and other nutrients are provided to soil microbes, which result in augmentation of their population. This helps in organic matter decomposition, biological nitrogen fixation, solubilization of insoluble phosphates and availability of plant micro-nutrient’s

There is improvement in soil structure, water holding capacity, drainage ban exchange capacity, seed germination and reduction of soil erosion

Humid substances released as byproducts of soil microbial activity increase the efficiency of bio and chemical fertilizers.

Proliferation of plant parasite, soil nematodes is checked

Resistance of plants to pest attack is increased
