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 minimises the need for water when treating 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.


In July 2019, Renergon handed over the first technical drawings and the specifications for planning the work on site to the Indian partner. A site of 20,000 m2 was acquired for the installation of the plant and a composting area. In the meantime, all official approvals for the project have been obtained and classified in the best possible category. Main construction work is nearly completed and all machinery have been delivered. The roof of the yard shaft is still to be built as well as some insolation and electrical wiring. The delays were due to supply-chain and delivery perturbations caused by the pandemic. The project is expected to be completed by the end of 2024.
