Paddy straw presents a significant crop-residue management challenge.

At Radha Raman Green Energy, agricultural residue such as paddy straw is given a productive second life by utilising it as feedstock for renewable biogas production.

Instead of being treated simply as waste, agricultural biomass can become an energy resource — an alternative resource pathway that contributes toward addressing the wider crop-residue management challenge.

The Story

EIGHT STEPS
OF A SECOND LIFE.

THE CHALLENGE

Crop-residue management. Large volumes of paddy straw are generated after harvest, and managing that residue remains a significant regional challenge.

THE RESOURCE

Paddy straw. Viewed as a resource rather than a residue, straw carries energy value that can be recovered biologically.

THE PREPARATION

Preparing biomass for digestion. Straw is collected, handled and prepared to a condition suitable for controlled biological processing.

THE TRANSFORMATION

Anaerobic digestion. Organic material is digested in an oxygen-free environment using plug-flow / dry-digestion based technology.

THE ENERGY

Biogas. The biological process generates methane-rich raw biogas.

THE REFINEMENT

Biomethane. Raw biogas is treated and upgraded to increase methane concentration to the required quality.

THE OUTPUT

Compressed Bio-Gas. Upgraded biomethane is compressed to produce CBG.

THE CIRCULAR RETURN

FOM for agricultural use. Digestate from the process provides the basis for Fermented Organic Manure, returning organic material to agriculture.

FROM AGRICULTURAL RESIDUE
TO RENEWABLE FUEL.
