Greenjoules | 2nd-Generation Biofuel & Renewable Diesel

Sustainable Development Goals

SDG 12 – Responsible Consumption and Production, SDG 13 – Climate Action, SDG 7 – Affordable and Clean Energy, SDG 9 – Industry Innovation and Infrastructure

Company Overview

Greenjoules Private Limited is a clean energy technology manufacturer headquartered in Pune, India. Established in 2018 by Viraraghavan Sankaran, Shweta Viraraghavan, Sethunath Ramaswamy, and Radhika Viraraghavan, the enterprise produces second-generation drop-in biofuels designed to replace fossil fuels without requiring modifications to existing engines or industrial infrastructure.

The organization processes agricultural residues and agro-industrial waste into renewable liquid and gaseous fuels. Its core solution centers on a proprietary thermochemical conversion process that converts waste carbon into fuels that match fossil fuel performance standards. By utilizing non-food agricultural waste, Greenjoules eliminates the food-versus-fuel conflict associated with first-generation biofuels.

Greenjoules operates a commercial biorefinery in Chakan, near Pune, Maharashtra, and is expanding production through greenfield facility developments in Raipur, Chhattisgarh. Key organizational milestones include obtaining independent ISCC Biocircular certification, securing Series A institutional equity funding led by Blue Ashva Capital, and establishing commercial fuel supply relationships with multinational enterprises across the chemical, consumer goods, and technology sectors.

Why These SDGs Matter

SDG 7 is directly addressed through the commercial manufacturing of second-generation renewable diesel and bionaphtha, providing industrial users with clean alternative energy sources to substitute fossil fuels.

SDG 9 aligns with the enterprise’s development of indigenous thermochemical processing technology and biorefinery infrastructure, advancing sustainable industrial processing and green chemistry capabilities within emerging markets.

SDG 12 is supported as Greenjoules utilizes agricultural residues and crop waste that would otherwise be burned in open fields, converting low-value waste streams into industrial fuels and usable by-products.

SDG 13 is advanced by supplying drop-in renewable fuels that deliver significant lifecycle carbon footprint reductions compared to conventional fossil diesel and petrochemical feedstocks.

Products & Services
  • Renewable diesel liquid fuel for industrial boilers and heavy vehicles

  • Bionaphtha renewable chemical feedstock for petrochemical and industrial processing

  • Upcycled biochar for agricultural soil amendment and carbon sequestration

  • Extracted refined silica for industrial applications and material formulations

  • Activated carbon products derived from biorefinery process streams

  • Renewable gaseous fuel fractions for industrial heating applications

Business Challenges Solved
  • High Scope 1 greenhouse gas emissions from fossil diesel combustion

  • Open field stubble burning and localized agricultural waste air pollution

  • High sulfur emissions from conventional heavy residual fuels

  • Infrastructure modification costs associated with non-drop-in biofuel blending

  • Volatility in fossil fuel procurement prices for commercial boiler operations

  • Supply chain reliance on food crop feedstocks for biofuel production

Approach & Methodology

Greenjoules utilizes a proprietary thermochemical conversion methodology to transform agricultural residues and agro-industrial waste into second-generation biofuels. The technical architecture relies on green chemistry principles, subjecting non-food biomass such as paddy straw and sugarcane processing residues to controlled thermal and catalytic reactions. This process breaks down complex lignocellulosic structures and recombines carbon molecules into hydrocarbons that match the physical and chemical properties of conventional fossil fuels.

The manufacturing process is engineered for drop-in compatibility, producing renewable diesel and bionaphtha that meet standard specifications for High Speed Diesel. The resulting liquid fuels can be used directly in existing internal combustion engines, commercial fleets, and industrial boilers without requiring mechanical retrofits or specialized blending infrastructure.

Greenjoules integrates a zero hazardous waste operating model where process by-products are collected and refined into secondary materials. Solid residues are processed into biochar for agricultural soil enrichment, refined silica, and activated carbon, while lighter gaseous fractions are captured for energy recovery within the biorefinery. The entire production flow undergoes third-party traceability audits under the ISCC Biocircular certification framework to verify chain of custody, mass balance accounting, and greenhouse gas savings.

Market Position

Greenjoules operates within the second-generation advanced biofuel and renewable chemical market segment. Its primary customers include multinational industrial enterprises, consumer goods manufacturers, chemical producers, and commercial fleet operators seeking Scope 1 emission reductions.

The enterprise differentiates its market position by manufacturing drop-in fuels from agricultural waste rather than food crops or vegetable oils. By utilizing proprietary thermochemical processing rather than standard transesterification, Greenjoules produces renewable diesel that meets standard diesel performance criteria without engine modification requirements.

Procurement Considerations
  • Verification of fuel compliance with national diesel fuel standards and emission norms

  • Audit of ISCC Biocircular chain of custody certificates for carbon accounting validation

  • Evaluation of volumetric supply commitments and long-term offtake contract terms

  • Assessment of fuel density, flash point, and cold flow properties for specific equipment

  • Analysis of local supply logistics and bulk storage tank compatibility

  • Review of total lifecycle carbon reduction calculations relative to conventional diesel

  • Examination of byproduct handling protocols and zero waste process documentation

Funding, Recognition & Ecosystem
  • Blue Ashva Capital (Series A Lead Investor)

  • Scitech Park Pune (Early-Stage Investor & Ecosystem Partner)

  • Start-up India Program Recognition

  • Automotive Research Association of India (ARAI) Fuel Testing Validation

  • Indian Institute of Technology (IIT) Madras Fuel Analysis Validation

Natnavi Analysis

Greenjoules Private Limited provides a practical industrial solution for Scope 1 decarbonization by addressing both agricultural waste management and fossil fuel dependency. By manufacturing second-generation renewable diesel and bionaphtha that function as drop-in replacements, the company removes capital expenditure barriers for industrial operators seeking immediate emission reductions without modifying existing boilers or vehicle fleets.

The primary operational advantage of Greenjoules lies in its proprietary thermochemical process and waste utilization model. Sourcing paddy straw and agro-industrial waste prevents open field burning, reduces localized air pollution, and avoids the land-use conflicts associated with crop-based biofuels. Furthermore, maintaining ISCC Biocircular certification provides industrial buyers with auditable data necessary for corporate sustainability disclosures.

Future growth depend on managing feedstock supply logistics and scaling production capacity. Collecting seasonal agricultural residues across rural regions requires structured supply chain coordination to prevent feedstock price volatility. As Greenjoules expands from its initial Chakan biorefinery to new greenfield sites in Chhattisgarh, maintaining process consistency and securing long-term corporate offtake agreements will be critical to scaling its market presence.
