Compressed Biogas (CBG) is the backbone of everything XEMX builds. We develop, construct, and operate anaerobic digestion plants that convert agricultural residue, press mud, and organic waste into Renewable Natural Gas — a drop-in replacement for fossil CNG and LNG.
India imports roughly half of the natural gas it consumes, while millions of tonnes of crop residue and organic waste decompose in open fields — releasing methane, a greenhouse gas around 84 times more potent than CO₂ over twenty years. Renewable Natural Gas solves both problems at once: it captures that methane and puts it to work in the existing gas grid, vehicles, and industry.
Policy momentum is unprecedented. The SATAT initiative targets a nationwide network of 5,000 CBG plants, and the CBG Blending Obligation (CBO) mandates blending of compressed biogas into CNG and PNG supply — starting at 1% and rising to 5% by FY 2028-29. Assured offtake agreements with oil marketing companies give CBG one of the strongest demand frameworks in Indian clean energy.

Methane's warming potency versus CO₂ over 20 years — captured and converted at every XEMX plant
Methane purity of upgraded CBG — fully interchangeable with fossil natural gas
Every XEMX plant runs a proven, industrial-grade process — engineered for high uptime, consistent gas quality, and complete valorisation of every input stream.
Agricultural residue, press mud, cattle dung, and organic waste are collected through structured farmer and industry partnerships — securing year-round supply within a tight radius of each plant.
Crop Residue · Press Mud · Organic WasteFeedstock is digested in sealed, temperature-controlled reactors where microbes break down organic matter into raw biogas — roughly 55–60% methane — under continuous process monitoring.
Sealed Digesters · Continuous MonitoringRaw biogas is purified to 90%+ methane, compressed to 250 bar, and dispatched as CBG — to oil marketing company outlets, city gas networks, and industrial offtakers under long-term agreements.
Purification · 250 bar · Assured OfftakeCBG enjoys one of the strongest demand frameworks in Indian clean energy — combining guaranteed offtake with a rising blending mandate.
Every XEMX CBG plant is the anchor of an integrated biorefinery — its co-products feed our fertiliser, biochar, and green chemicals platforms.
Feedstock suppliers, landowners, offtakers, and investors — join us in building India's waste-to-energy backbone. See our Pandharpur facility for proof on the ground.
