What is Bio-CNG
Bio-CNG (Bio-Compressed Natural Gas) is a renewable fuel derived from the purification and compression of biogas, which is produced through the anaerobic digestion of organic waste materials such as agricultural residues, municipal solid waste, and animal manure.
Key Features of Bio-CNG:
High Energy Efficiency: With a calorific value of about 52,000 kJ/kg, Bio-CNG offers significantly higher energy efficiency compared to raw biogas.
Environmental Benefits: Utilizing Bio-CNG can lead to substantial reductions in greenhouse gas emissions, making it a cleaner alternative to fossil fuels.
Versatile Applications: Bio-CNG is suitable for various uses, including transportation fuel, power generation, and as a replacement for conventional fuels in industrial processes.
By-products: The production process yields valuable by-products like high-quality organic fertilizers and food-grade carbon dioxide, enhancing the overall economic viability.
How It Works
Bio-CNG (Biological Compressed Natural Gas) is a renewable fuel produced by processing organic waste through anaerobic digestion, followed by purification and compression. Here’s an overview of how it works:
1. Anaerobic Digestion: Organic materials like agricultural waste, animal manure, and food scraps are broken down by microorganisms in an oxygen-free environment, producing biogas—a mixture primarily of methane (CH₄) and carbon dioxide (CO₂).
2. Biogas Purification: The raw biogas undergoes purification to remove impurities such as hydrogen sulfide, moisture, and CO₂, resulting in biomethane with a methane content of about 92–94%.
3. Compression: The purified biomethane is compressed to high pressures to produce Bio-CNG, which can be stored in cylinders or transported via pipelines for use as a clean fuel alternative.
Why You Should Use Bio CNG
Environmentally Friendly: Bio CNG emits significantly fewer greenhouse gases, making it a cleaner energy choice that helps fight climate change.
Reduces Fossil Fuel Use: Bio CNG is a renewable alternative that helps cut dependence on imported and non-renewable fossil fuels.
Lowers Pollution Levels: Using Bio CNG results in less air and noise pollution compared to diesel and petrol, improving public health and air quality.
