Organic Recycling Systems launches downdraft gasification pilot for shell waste
Organic Recycling Systems Limited has launched a pilot study for a 10 kg/h Downdraft Gasification System to process hard biomass agricultural residues like coconut and cashew shells. The trials at the Mahape facility aim to optimise charcoal yield and fixed-carbon content. The company plans to commercialise the technology if results are promising.

Organic Recycling Systems has expanded its waste-to-value platform by initiating a pilot study for a 10 kg/h Downdraft Gasification System at its NABL-accredited research centre in Mahape, Navi Mumbai. The thermochemical technology aims to convert hard biomass feedstocks, such as agricultural shell waste, into clean syngas and high-grade biochar through controlled partial oxidation. This development addresses the gap in India's bioenergy sector regarding hard biomass agricultural residues, which have largely remained unutilised.
The pilot study is currently conducting trials on four specific feedstocks: tender coconut shells, brown coconut shells, cashew nut shells, and groundnut shells. The primary objective of this phase is to map and optimise key process parameters to maximise charcoal mass yield while ensuring high fixed-carbon content. The downdraft configuration was selected for its low tar formation, and the system features an autothermal design that sustains process heat without an external fuel source.
Technology and Process Parameters
The ORS Research and Innovation Centre (ORS-RIC) is evaluating the impact of critical operating parameters, including equivalence ratio, residence time, and extraction volume, on the gasification process. The pilot is currently in the parameter optimisation phase, and no yield or quality results have been reported yet. The project is part of ORSL's broader strategy to develop a robust process framework for future scale-up and commercial deployment.
Research Portfolio and Accreditation
The downdraft gasification pilot adds to ORS-RIC's expanding research portfolio, which includes 7+ innovations in development across biochar, advanced catalysts, carbon membranes, CO₂ utilisation, and microalgae-based treatment systems. The centre received NABL accreditation under ISO/IEC 17025:2017 in February 2026.
Management Commentary
Mr. Yashas Bhand, Whole Time Director, Organic Recycling Systems Limited, stated that hard biomass waste represents a significant unaddressed category of agricultural residue in India. He noted that downdraft gasification offers a pathway to convert these materials into high-grade biochar and clean syngas, with commercialisation contingent on promising results from the systematic parameter mapping.
Dr. Manju Tanwar, Head – Research & Development, ORS Research and Innovation Centre, added that the study systematically evaluates the thermochemical challenges posed by the density, structure, and composition of hard biomass feedstocks. She emphasised that the current objective is to generate reliable operating data and identify optimal conditions for future scale-up.
If the technology is commercialised, ORSL projects it could reduce fuel and electricity costs and provide a marketable solution for stakeholders facing issues with hard biomass waste disposal.
