Raj Process Equipments & Systems Pvt. Ltd. is one of India’s leading compressed biogas plant manufacturers, delivering world-class turnkey solutions for sustainable fuel production. With decades of expertise and a proven track record, we transform organic waste into high-purity compressed biogas (CBG) — a renewable, eco-friendly alternative to fossil fuels.
As India advances toward a clean energy future, Raj Process proudly supports government initiatives like SATAT and GOBARdhan by designing and executing next-generation CBG plants across India and globally.
🔬 Biogas Generation Technology
Raj Process has developed a patented CSTR-based biodigester with a unique combination of central and lateral agitation. This innovation enhances biogas yield and waste treatment efficiency, making it one of the most advanced anaerobic digestion systems available.
What is a CSTR Biodigester?
A Continuous Stirred Tank Reactor (CSTR) biodigester processes organic waste — such as agricultural residues, food scraps, or sewage sludge — in the absence of oxygen. The result: valuable biogas (methane + CO₂) and nutrient-rich digestate for use as organic fertilizer.
