Company Overview

GPS Renewables is a Bengaluru-headquartered clean fuels technology and infrastructure company founded in 2012 by IIM Bangalore alumni Mainak Chakraborty and Sreekrishna Sankar. The company began as a captive biogas provider under its BioUrja product line, serving hotels, corporate campuses, and healthcare facilities, before expanding into an industrial-scale biofuels infrastructure company.

Today, GPS Renewables operates across the full biofuel value chain, spanning biogas, compressed biogas (CBG/RNG), second-generation ethanol, sustainable aviation fuel (SAF), and green hydrogen. Its capabilities extend from technology development and bioprocess design through engineering, procurement, construction (EPC), and asset ownership of large-scale plants.

A signature milestone is Asia’s largest municipal-solid-waste-based CBG plant in Indore, Madhya Pradesh, inaugurated by India’s Prime Minister in February 2022. The company has since scaled its footprint through joint ventures with Indian Oil Corporation (IGRPL) and Bharat Petroleum, alongside international investment from Sojitz Corporation of Japan.

GPS Renewables also acquired Germany-based Proweps Envirotech GmbH to strengthen its engineering base, and maintains design offices in Bengaluru, Gurugram, Mumbai, and Stuttgart. The company holds ISO 9001, ISO 14001, and ISO 45001 certifications, reflecting its quality, environmental, and occupational health management systems. It operates as GPS Renewables Private Limited, an active company registered with the Ministry of Corporate Affairs, India.

Why These SDGs Matter

GPS Renewables directly advances SDG 7 by converting organic and agricultural waste into biogas, CBG, ethanol, and green hydrogen, expanding access to affordable, clean fuel alternatives. Its large-scale EPC projects and joint ventures with public-sector oil companies create skilled engineering and rural employment, supporting SDG 8, particularly through feedstock sourcing from farmers. The company’s urban biogas installations at hotels, tech parks, and corporate campuses process organic waste at the point of generation, contributing to SDG 11 by improving municipal solid waste management. By transforming agricultural residues such as paddy straw, an otherwise burned waste stream, into usable fuel, GPS Renewables supports SDG 12’s resource-efficiency and waste-valorization objectives. Its core business of displacing fossil fuel demand with biomethane, ethanol, and SAF directly reduces greenhouse gas emissions, aligning with SDG 13’s climate action mandate.

Business Challenges Solved
  • Uncontrolled organic and municipal solid waste accumulation
  • Agricultural residue and paddy straw burning causing air pollution
  • Limited domestic clean fuel production capacity for aviation and transport
  • High dependence on imported natural gas and fossil fuels
  • Lack of end-to-end EPC expertise for large-scale biogas infrastructure
  • Need for decentralized, on-site waste-to-energy solutions at commercial properties
Approach & Methodology

GPS Renewables operates across three integrated business verticals: Technology Delivery, Project Execution, and Biofuel Asset Ownership. On the technology side, the company designs bespoke bioprocess systems tailored to specific feedstocks, including municipal solid waste, source-separated organics, paddy straw, and press mud cake, backed by in-house R&D and academic collaborations such as its work with CSIR-National Chemical Laboratory on ethanol-to-SAF conversion using a patented catalyst.

For project execution, GPS Renewables functions as an EPC contractor, managing design, procurement, construction, and commissioning for biogas and CBG facilities, including for third-party clients such as NTPC Green Energy. The company’s engineering offices in Bengaluru, Gurugram, Mumbai, and Stuttgart support this delivery capability, supplemented by proprietary equipment such as gas purification units and, through its Proweps and Biogastechnik Süd partnerships, specialized paddle agitators for anaerobic digestion.

Its asset ownership arm, GPSR Arya, develops and operates climate infrastructure directly, often through joint ventures with public-sector partners such as Indian Oil Corporation and Bharat Petroleum, where GPS Renewables typically holds a co-development or equity stake. This three-pronged model allows the company to generate revenue from technology licensing, EPC contracts, and long-term asset operation simultaneously, rather than depending on a single revenue stream.

Market Position

GPS Renewables positions itself as India’s leading full-stack biofuels company, with a business model spanning technology, EPC execution, and asset ownership rather than a single point in the value chain. Its primary customers include hotels, corporate campuses, government bodies, and large public-sector oil marketing companies such as Indian Oil Corporation and Bharat Petroleum, with which it has formed dedicated joint ventures for CBG infrastructure development. The company differentiates itself through in-house engineering depth, an active order pipeline covering dozens of large-scale CBG projects, and expansion into adjacent clean fuel categories including second-generation ethanol, sustainable aviation fuel, and green hydrogen. Its acquisition of German engineering firm Proweps Envirotech and international investment from Japan’s Sojitz Corporation reflect a strategy of combining domestic project execution capacity with global technology and capital partnerships.

Procurement Considerations
  • Verify current ISO 9001, 14001, and 45001 certification status for the specific project scope
  • Confirm feedstock availability and logistics for the intended plant location
  • Assess EPC timeline commitments against the buyer’s project deadlines
  • Review joint venture or ownership structure if procuring through a GPSR Arya-developed asset
  • Evaluate long-term operations and maintenance (O&M) service terms
  • Confirm regulatory compliance for CBG, ethanol, or SAF output under applicable Indian energy mandates
  • Request references from comparable completed projects, such as municipal or industrial-scale CBG plants

Natnavi Analysis

GPS Renewables occupies a distinctive position in India’s cleantech landscape as one of the few domestic players operating across the full biofuels value chain, from technology design through EPC execution to asset ownership. This vertically integrated model reduces the company’s dependence on any single revenue stream and has enabled it to secure joint ventures with two of India’s largest public-sector oil marketing companies, Indian Oil Corporation and Bharat Petroleum, a signal of institutional confidence in its execution capability.

The company’s evolution from a modest captive biogas provider in 2012 to a firm delivering Asia’s largest municipal-waste-based CBG plant reflects consistent technological and operational scaling. Its expansion into sustainable aviation fuel and green hydrogen, backed by academic collaboration with CSIR-NCL, positions it to participate in emerging clean fuel categories ahead of India’s SAF blending mandates beginning in 2027.

A potential limitation for procurement teams to weigh is the company’s reliance on large, capital-intensive infrastructure joint ventures, which can extend project timelines and introduce dependency on partner institutions. Its debt-heavy financing structure, while common in infrastructure development, also warrants due diligence on project-specific financial terms. Overall, GPS Renewables represents a credible, well-capitalized partner for organizations seeking biogas, CBG, or emerging clean fuel infrastructure in India.
