These plants serve the following purposes
1. Environment-friendly disposal of biodegradable waste, which is the need of the hour considering mass pollution everywhere.
2. Generation of a fairly good amount of fuel gas, which will definitely support the dwindling energy resources.   
3. Generation of high-quality manure, which would be free of weed seeds and an excellent soil conditioner. This is very important for replenishing fast decreasing resources of productive soils.
4. It would reduce the menace of street dogs and other nuisance animals and pathogens, as a major portion of biodegradable waste on dumping yards would no more be available for their feeding.
5. Employment generation.
6. Environment protection by helping in the maintenance of elemental cycles in nature. 

About the Project: 
We at EWS Greentech, design, construct and operate projects, based on anaerobic digestion and biogas production. Combine energy efficiency with long-term sustainability, benefiting both businesses and the environment. We provide technologies for the production of energy from solid organic wastes, agricultural industrial wastewater and biomass. We design, manufacture and deliver all types of biogas plants i.e. Flexi biogas plants, Mid-sized FRP biogas plants and Industrial biogas plants, as per the customers' requirement.

Bio-CNG:- 

Clean and renewable fuel, has vast potential in India. It can be a supplement to petroleum products if used in compressed form in the cylinders. Biogas originates from the bacterial process during biodegradation of organic material under anaerobic conditions. Methane is the most valuable component under the aspect of using biogas as a fuel; the other components do not contribute to the calorific ("heating") value and thus are "washed out" in our purification plants in order to obtain a gas with almost 93-97% CH4. Methane is the flammable component in biogas.

Bio-Fertilizer (Solid Manure):-

Biogas systems produce a nutrient-rich fertilizer. Manures contribute to the fertility of the soil by adding organic matter and nutrients, such as nitrogen, that are utilised by bacteria, fungi and other organisms in the soil. The manure will be packed to sell to the farmers for their various applications. 

Bio-Fertilizer (Liquid Manure):- 

Biogas system produces a nutrient-rich liquid fertilizer, called “biogas-slurry”. Biogas-slurry is a safe organic liquid fertilizer that can be applied to crops, flowers, and trees. The slurry can be separated out through solid-liquid separate. The Fertilizer will be packed to sell to the farmers for their various applications.  

Benefits:

Bio-CNGs is gaining wide popularity as Vehicle Fuel, Power Generation & Bio-Fertilizer is very good for fast deteriorating soils.
