For the effective operation of a bio waste treatment plant, electricity is quite essential. The main advantage of the waste to electricity project is that no external power is required for the operation of the plant. Click here to see photos. The power generated in the treatment plant can be utilized to meet the in-house requirement completely. Excess quantity can be utilized for any type of off-grid application, such as street lighting.
The generation of electricity through conventional method is a costly affair. Severe environmental problems will be caused on account of electricity generation through coal, diesel etc. Even in the case of hydro electric Projects, many environmental problems will arise in and around project area through deforestation.
The generation of electricity using biowaste treatment plant is not a costly concern. Of course the installation cost of a Waste to Electricity Project may be a little high. But the recurring expenses will not be substantial for the operation of the plant. In the plant, biogas is being generated everyday through anaerobic decomposition of waste.
Normally 1.5 kilowatt electricity can be produced from one cubic meter of biogas. Depending on the percentage of methane content in biogas, power generation may slightly vary.

The gas can be utilized as operational fuel in gensets. Before feeding biogas as fuel in gensets, the gas has to be passed through a gas scrubber to remove unwanted particles, gases, moisture, etc.
There are two types of generators used to generate electricity from biogas. One is the duel fuel model and the other is 100% biogas model. Duel fuel models are diesel gensets. In this system the biogas is connected to the generator through air mix. Once the biogas is passed through the gensets, automatically consumption requirement of the diesel is reduced. Normally duel fuel gensets are working in 80% - 20% mode.
In 100% biogas engines, no other fuel is required either for starting or for operation. Any type of petrol engine can be modified for operating the same using biogas as operation fuel. The imported models of 100% biogas engines are very costly ones and the maintenance of such systems is very expensive. BIOTECH has developed 100% biogas engines. These engines are installed in various projects and the performance of all of them is very good.
