In the heart of Cuddalore, Tamil Nadu, SLR Energy has been leading the charge in sustainable energy solutions since its inception in 2017. Specializing in the manufacturing of gas generators, gas producers, and bio-organic fertilizers, SLR Energy has become a beacon of innovation in the renewable energy sector.
Bio-CNG (compressed natural gas) is produced through the anaerobic digestion of organic waste materials, primarily agricultural residues, food waste, and other biomass. The process involves the breakdown of organic matter by bacteria in an oxygen-deprived environment, leading to the production of biogas. Biogas is primarily composed of methane, carbon dioxide, and trace amounts of other gases. The key difference between biogas and Bio-CNG lies in the refinement process. While biogas is a raw mixture, Bio-CNG undergoes a purification process to remove impurities and increase its methane content, making it comparable to conventional natural gas. This purification allows Bio-CNG to be used as a vehicle fuel.The plant boasts a daily capacity of 7000 cubic metres, a testament to their commitment to harnessing the power of waste for a cleaner future. Operating at full tilt, SLR Energy fills an impressive 4 to 5 casket cylinders daily, utilising a diverse range of inputs including pressmud, sugarcane waste, milk waste, and cow dung. It handles a lot of waste every day, around 40 to 80 tons, and at the same time, it gets 12 to 16 tons of slurry for processing.
What sets SLR Energy apart is their meticulous and eco-friendly biogas production process. The waste is fed into the plant, creating a homogeneous mixture that undergoes hydrolysis. Over a span of 45 days, 10% to 12% solid digest is inserted into anaerobic digesters, yielding biogas. This gas undergoes a rigorous purification process, removing CO2, moisture, H2S, N2, and O2 before being stored in caskets.
BIO CNG PRODUCTION PROCESS
Step 1: Biomass Collection
Gather organic waste materials such as agricultural residues, food waste, or animal manure.
Step 2: Pretreatment
Remove any impurities or non-biodegradable materials from the collected biomass.
Step 3: Anaerobic Digestion
Place the pretreated biomass in an anaerobic digester, a sealed container without oxygen. Bacteria break down organic matter into biogas through fermentation.
Step 4: Biogas Upgradation
Biogas typically consists of methane, carbon dioxide, and trace gases. Use a gas upgradation system to separate methane from carbon dioxide and other impurities, producing purified biogas.
Step 5: Compression
Compress the purified biogas to increase its density, making it suitable for use as a vehicle fuel.
Step 6: Storage
Store the compressed biogas in tanks for future use.
Step 7: Distribution
Transport the Bio-CNG to fueling stations where it can be distributed to end-users.
Step 8: Utilization
Use the Bio-CNG as a clean and sustainable fuel for vehicles, replacing traditional natural gas.
The transformation doesn’t stop there. The residual slurry metamorphoses into organic fertilizer, a product that SLR Energy proudly sells, further contributing to the circular economy. However, the journey has not been without its challenges. SLR Energy has faced hurdles in the marketplace, navigating obstacles to create awareness among the people. Despite the struggles, the company remains steadfast in its mission, not only for its own success but also for the greater environmental benefits derived from effective waste management activities. SLR Energy stands as a symbol of sustainable progress, turning challenges into opportunities for a greener and cleaner tomorrow.
