Core Production Process

The core of CBG production lies in transforming organic waste into highly purified biogas, which is then compressed to increase its energy density. The main stages of production include:

1. Feedstock Sourcing and Preparation

• Organic Waste Aggregation: Diverse organic materials—including agricultural leftovers, animal manure, discarded food, and municipal sludge—are gathered from farms, factories, and urban centers.
• Pre-treatment Protocols: Based on the feedstock's composition, preliminary steps like shredding, grinding, and blending are utilized to maximize biogas yields and streamline the digestion phase.

2. Anaerobic Digestion (AD) Process

• Biogas Generation: The conditioned feedstock enters anaerobic digesters, undergoing microbial fermentation in an oxygen-free environment.
• Methane Emission: Throughout the AD process, microbes decompose the organic material, yielding methane (CH4) and carbon dioxide (CO2) as the primary byproducts.

3. Biogas Purification and Upgrading

• Extracting Impurities: The raw biogas is subjected to purification to strip away moisture, hydrogen sulfide (H2S), and other trace elements that could compromise equipment and gas quality.
• Desulfurization Techniques: H2S is typically eliminated via specialized scrubbing systems or biological desulfurization processes to halt corrosion and preserve the purity of the gas.

4. Gas Compression

• Biogas Compression: After purification, the biogas is compressed using dedicated compressor systems to increase its density, making it easier to store, transport, and utilize efficiently.
• Pressure Regulation: Compression units carefully control and maintain the pressure of the gas so that it meets the required standards for various uses such as vehicle fuel and industrial applications.

5. Quality Control and Certification

• Gas Testing: Compressed biogas is thoroughly analyzed to confirm that it meets industry specifications for purity, composition, and operational performance.
• Certification Process: Authorized testing agencies and regulatory authorities may evaluate and certify the gas quality to ensure safety and compliance before distribution or commercial use.
