We’re full of gas.
India’s untapped biomethane potential — enough to fill 1.4 billion CBG cylinders.
Laid end to end: 54 times around the Earth.

Sixteen people. Thirty-plus applications. No external vendors running the core. As Jithin Thankachan puts it: “Small team, real purpose — that’s CSL.” Every tool is built, owned, and maintained in-house — held together not by headcount, but by collaboration and a team that treats the work as more than just software.

Kerala has warmed 1.7°C since 1901 — and the hillsides are paying the price. At Haritha Keralam Summit 2026, Sachin Gracious made the case for something different: “Most warning systems react after the risk. We’re building tools that predict it.”

The standard move: buy an enterprise ERP, pay the licence, accept the limits. GPS Renewables didn’t. “Instead, we took a bolder path” — building on Odoo 17, open-source, fully customised, entirely in-house.

Three people. No systems. No playbook. That was CSL in 2022. As SVP Arun Madhavan put it: “The software team at GPSR is not treated as an IT Department, but as a Climate Lab.” Everything was built from scratch — and now the team is turning outward, toward software that responds to the climate crisis itself.

Solid–Liquid Separation (SLS) plays a critical role in biogas plants by maintaining digester stability, enabling efficient solids recovery, and ensuring reliable, continuous plant operations through disciplined monitoring and maintenance.

The Barabanki plant’s journey to 15 TPD CBG in 15 months showcases how disciplined operations, engineering improvements, and strong teamwork enabled successful large-scale production from paddy straw.

Jhajjar Unit-1’s maintenance journey (Nov–Dec 2025) highlights how disciplined preventive care, timely interventions, and strong teamwork strengthened plant reliability and operational stability.

Over the past few years, the O&M function has evolved significantly—from a stabilization-focused phase to a more structured and mature operation

Across India’s growing CBG sector, operational efficiency, predictability and real-time data for decision-making are essential for scale.

We’ve developed, demonstrated, and commercialized a milestone in-house technology — the OptiMill, our hammer mill made to pre-process segregated organic waste.

Paddy straw is full of biomethanation promise, but it is stubborn & extremely hard to break down. OptiBurst, our cavitation-based pre-treatment solution is made for this.
