As industries and governments increasingly focus on decarbonization, sustainable waste management, and energy security, Bio-Compressed Biogas (Bio-CBG) has emerged as a highly effective renewable fuel solution. Our integrated Bio-CBG project demonstrates how organic waste can be transformed into high-quality green energy while simultaneously creating valuable bio-fertilizer products, supporting a true circular economy model.
The facility is designed to convert a wide range of biodegradable feedstocks—including agricultural residues, press mud, cow dung, food waste, Napier grass, and other organic materials—into renewable Bio-CBG through advanced anaerobic digestion and gas upgrading technologies. The upgraded Bio-CBG serves as a sustainable substitute for LPG, PNG, and conventional fossil fuels across transportation, industrial, and commercial applications.
Advanced CSTR-Based Anaerobic Digestion Technology
At the heart of the plant is our Continuous Stirred Tank Reactor (CSTR) anaerobic digestion system, engineered to maximize the biological conversion of organic matter into biogas. Continuous mixing and controlled operating conditions ensure efficient substrate degradation, improved microbial activity, stable process performance, and enhanced methane generation.
Key Features
Conversion of organic waste into renewable Bio-CBG
Sustainable alternative to LPG, PNG, and conventional fossil fuels
Advanced CSTR-based anaerobic digestion technology
Optimized organic waste degradation and biogas generation
Stable biological performance with continuous operation
Higher methane yields through controlled process conditions
High-Efficiency Biogas Upgrading and Purification
A key differentiator of this project is the implementation of our patented gas purification technology, combining BioChemical Scrubbing with Chilled Water Scrubbing. This integrated upgrading process effectively removes impurities such as carbon dioxide, hydrogen sulfide, moisture, and other contaminants, resulting in high-purity Bio-CBG with superior methane concentration.
The upgraded gas consistently meets commercial fuel standards, ensuring reliable performance, improved energy value, and long-term operational efficiency.
