Biomethane enrichment from agricultural biomass residues.
Developing utility-scale Compressed Biogas (CBG) facilities to convert regional biomass streams into high-purity renewable methane, displacing fossil natural gas in transport and industrial thermal networks.
Decarbonizing industrial heat and transport through anaerobic enrichment.
Compressed Biogas (CBG) is purified biomethane produced via the anaerobic microbiological digestion of crop residues and organic agro-waste. Once desulfurized and stripped of carbon dioxide, it delivers an identical calorific value to fossil compressed natural gas.
Rivanta Green is developing modern CBG infrastructure to inject drop-in renewable methane directly into regional gas grids and commercial logistics cascades, converting liability agricultural waste into continuous baseload energy.
City Gas & Industrial Grid
Supplying high-caloric biomethane directly into regional City Gas Distribution (CGD) networks to displace fossil natural gas in ceramic, metallurgical, and manufacturing plants.
Fermented Organic Manure
Digestate co-product is dewatered and enriched into high-humus solid FOM pellets and liquid bio-nutrients, returning organic carbon and micronutrients to regional soils.
Green Commercial Mobility
Compressed Bio-CNG for commercial logistics fleets and long-haul transport corridors, reducing particulate matter and tailpipe greenhouse emissions by up to 85%.
Caloric parity with pipeline compressed natural gas.
Purified biomethane complying strictly with IS 16087 standards for automotive and industrial grid injection.
High-efficiency selective hollow-fiber membrane separation ensuring maximum volumetric energy density.
Biological desulfurization trickling filters combined with zinc oxide polishing beds for pipeline integrity.
High-pressure multistage reciprocating compressors for mobile cascade storage and city gas network off-take.
Multi-substrate conditioning & biological digestate recovery.
Beyond clean methane, the solid digestate residue is refined into Fermented Organic Manure (FOM) — returning vital soil carbon, nitrogen, phosphorus, and moisture retention to agricultural farmlands.
Agronomic Field Straw & Stubble
Paddy straw, wheat straw, and crop stalks shredded and conditioned to eliminate open-field burning while unlocking hemicellulose sugars.
Agro-Processing Residues & Pressmud
Milling byproducts, sugarcane pressmud, and distillery decanter wastes offering rapid methanogenic kinetics and high volatile solids.
Engineered Co-Digestion Mixtures
Precision C:N ratio balancing across multi-substrate blends to ensure continuous digester stability and maximize biomethane yield per ton.
