Praj to set up compressed biogas plant for HPCL ANI | Updated: Mar 10, 2021 17:05 IST Praj will deploy RenGas technology developed by using proprietary microbe to produce compressed biogas from rice straw. The project has the capacity to process 35,000 tonnes of rice straw as feedstock to generate 5,250 tonnes of compressed biogas annually. In addition, the project will also generate 23,000 tonnes high quality solid bio-manure and 350,000 tonnes of liquid bio-manure for ferti-irrigation. This project has the potential to save up to 15,000 tonnes of carbon emissions per year, the company said in a statement. It will be completed and commissioned within a year. The project will contribute to the government's sustainable alternative towards affordable transportation (SATAT) initiative with an objective to promote compressed biogas as an alternative, green transport fuel.
