Swiss Contribution

Founded in 2010, Renergon International Ltd. has proven experience in solid waste fermentation. The entire project planning and plant design, as well as the biogas plant’s construction supervision and commissioning are ensured by Renergon, in close cooperation with „Cities Innovative Biofuels Ltd.“, the Indian partner. In addition, the knowledge sharing and technology transfer take place through the education and training of the partner company’s employees.


A solid waste fermentation plant will be installed near Patiala, which will treat cattle manure and rice straw, recovered within a maximum radius of 5 km. Renergon’s solid waste fermentation (dry digestion in fermenter boxes) does not require a mixable and pumpable substrate liquid blend, which greatly minimizes the need for water when utilizing organic waste. The biogas produced is to be processed into bio-CNG (compressed natural gas) through gas treatment and stored in gas cylinders. The use of rice straw mitigates the massive disposal problem on site (burning straw in the fields) and thus ensures a huge improvement in air quality. Furthermore, a valuable multi-nutrient and humus fertilizer is produced in the form of marketable composts.
