Bio CNG from Sewage Based Biogas Plant

Anarobic Energy Private Limited is producing Bio CNG from Biogas. The company plans to set up its first biogas plant using new to the market technology to produce bio CNG at Haridwar based on sewage sludge available at a treatment plant at Jagjeetpur, Haridwar. The company proposes to generate biogas, refine the biogas to produce bio CNG using technology that is new to the market and generate revenue by its sale. Generation of bio CNG requires two distinct processes: i) Generation of biogas from substrate via anaerobic digestion and ii) Purification / up -gradation of biogas to bio CNG. The technology developed enhances methane production essential for CNG more than conventionally produced methane. This has resulted in higher production of bio CNG from the same amount of raw material thus reducing raw material cost on one hand and reduced load on the scrubbing system on the other.
