Turning an invasive weed and waste biogas into India's next clean-fuel industry.
YGPL develops circular bioenergy complexes that convert ecological liabilities — water hyacinth choking Assam's wetlands, flared biogas in Tamil Nadu — into compressed biogas, green hydrogen, cryogenic dry ice, organic fertilisers and carbon credits, backed by signed offtake LOIs and national mission funding.

A decade of renewable energy, three India-first plants
Yogan Green Private Limited began as a special purpose vehicle to build a state-of-the-art Compressed Biogas cum Dry Ice plant near Palani — the first of its kind in India where CO₂ is captured and converted into dry ice — under the SATAT (Sustainable Alternative Towards Affordable Transportation) and GOBARdhan schemes. That founding idea now anchors a portfolio of three India-first projects across Tamil Nadu and Assam.

The founding project of the YGPL SPV — a 12 TPD Compressed Biogas cum Cryogenic Dry Ice plant under the SATAT & GOBARdhan schemes, recognised by MNRE as a 'Flagship Project'. India's first plant designed to capture CO₂ from biogas upgrading and convert it into dry ice — the innovation now scaled at Veppur and Bokakhat.
Feedstock: Giant King Napier Grass — the high-yield energy crop behind our landowner partnership programme
For 130 years, water hyacinth has been Assam's slow-motion ecological disaster. The Bokakhat complex is the first intervention designed to permanently reverse it — an industrial-scale circular biorefinery that restores the beels, revives fishing livelihoods, avoids megatonnes of methane, and pays for itself four times over. Submitted to the Hon. Chief Minister of Assam through the Dept. of Industries & Commerce; an MNRE 'Flagship Project' under the GOI GOBARdhan Scheme, anchored by AIG Direct LLC's US$3.0M Tranche A and three executed LOIs.

₹1,880 Cr/yr
Annual economic loss to Assam · beels emit 8.5 lakh T of methane a year (2.38 Cr T CO₂e)
Every prior method — manual removal, chemicals, biological control — failed because removal never outpaced regrowth. Only continuous industrial harvesting at 1,200 TPD exceeds the weed's biological regrowth rate — for the first time in 130 years removal outpaces growth, and beel ecology restores naturally within about 18 months.

Before & after — changing the lifeline of Bokakhat
The same beel, eighteen months apart. Once continuous harvesting at 1,200 TPD outpaces regrowth, sunlight and oxygen return to the water — and with them, everything the water carries: fish, boats, irrigation, and income.
Before — the crisisA beel sealed shutDense hyacinth mats block sunlight and oxygen; decomposition turns the water acidic (pH 4.5–5.0), releases methane and hydrogen sulphide, kills aquatic life and traps boats. Fishing incomes collapse 64%.After — the lifeline restoredOpen water, working boatsContinuous harvesting feeds the biorefinery while the beel breathes again — oxygen and fish stocks recover, boats and irrigation canals reopen, and every tonne removed becomes CBG, dry ice and fertiliser revenue.
These illustrations can be swapped for site photography — drop your images into assets/ (e.g. beel-before.jpg, beel-after.jpg) and I'll wire them in.
Fishing incomes recoverFrom the ₹8,000/month crash back toward the ₹22,000/month norm as 17,500 families return to open water.
Waterways & irrigation reopenCountry boats, ferries and irrigation canals move again — reconnecting villages the mats had cut off.
Healthier communitiesStagnant, mosquito-breeding mats give way to flowing water — easing the disease burden hyacinth-infested beels impose on surrounding areas.
Kaziranga tourism securedRestored buffer beels protect the wetland mosaic that anchors the UNESCO landscape and its visitor economy.
Bokakhat Skill Development Centre · adjacent to the project site
Training the Northeast's green-economy workforce, next door to the plant
Alongside the biorefinery, YGPL is setting up the Bokakhat Skill Development Centre on the same campus — the first industry-embedded skill centre in Northeast India's green economy. Trainees learn on a working plant, not in a classroom simulation, and graduate straight into jobs the region is creating.
What it teaches: biorefinery operations, plant instrumentation, cold-chain logistics and industrial safety.
Who certifies: NIELIT Jorhat, IIT Guwahati and SICGIL India.
Where graduates go: priority placement in the Bokakhat Biorefinery, the 50-unit Assam replication programme, and NRL's own ecosystem — creating a captive talent pipeline that cuts regional training costs by ₹2–3 Cr/yr.
How it's funded: proposed under NRL's CSR programme (₹3–4 Cr/yr for 5 years into the Biorefinery & Skill Development SPV) together with the harvester fleet.

Alongside NRL — a refinery and a biorefinery, 15 km apart
Numaligarh Refinery Limited is the natural anchor for Bokakhat: the site sits in NRL's own backyard in Golaghat district, beside the Kaziranga UNESCO buffer beels, and the partnership reuses the exact support template NRL has already extended to its own bamboo bio-refinery ecosystem. Five direct requests are before NRL for in-principle Board consideration — each one mirrored by a concrete gain for NRL itself.
What Yogan Green requests of NRL
Land — 15 acres in the Bokakhat Industrial Area: notified land with clear title, adjacent to NRL. Saves land CapEx; co-location enables shared utilities and security.
Power at 50% tariff (₹3.50/kWh under Assam Industrial Policy 2021) — saves ₹3.08 Cr/yr; grid drawal is standby only, since captive tail-gas gensets and 500 kWp rooftop solar meet base demand.
Process water & steam at fixed cost from NRL's existing infrastructure, plus 30 TPD bamboo powder (or NRL-facilitated 40–45 TPD local bamboo at NRL's procurement cost) — avoids ₹4–5 Cr water-treatment CapEx and stabilises digestion.
100% CBG offtake for 10 years — 20 TPD (≈1,000 MMBtu/day) at the GOBARdhan administered price of ₹2,110/MMBtu. Because the price is set by the Government of India, NRL commits to volume, not price risk — while de-risking ₹66 Cr/yr, 33% of project revenue.
CSR investment of ₹3–4 Cr/yr for 5 years (₹15–20 Cr — under 1% of NRL's annual CSR obligation on a PAT exceeding ₹2,000 Cr) into the harvester fleet and the Bokakhat Skill Development Centre.
Equity invitation — a 20–35% stake in the project SPV with a board seat: venture-grade returns with infrastructure-grade risk.
What NRL gains in return
CBG Blending Obligation compliance at its doorstep — CBO-compliant CBG 15 km away with zero logistics risk, as blending mandates climb 1% » 3% » 4%.
A flagship ESG story in the Kaziranga landscape — restoration of the very beels that secure the region NRL operates in, with reportable outcomes: 27.6 lakh T CO₂e/yr avoided, 18,000 ha restored, 17,500 fishing families uplifted.
A captive trained talent pool — 450+ locals certified annually with priority placement, cutting NRL's own training costs by ₹2–3 Cr/yr; the first industry-embedded skill centre in Northeast India's green economy.
Scope-3 & carbon co-claiming — VCS / Gold Standard credits with a Ramsar + UNESCO premium (~₹4.6 Cr/yr indicative) and joint visibility at G20, COP and ASEAN forums.
Anchor offtaker of first resort for the 50-unit Assam replication programme (2030–33) — positioning NRL as India's leading green PSU.
NRL is a Public Sector Undertaking: each request requires consideration and approval by the NRL Board and, where applicable, its shareholders. The proposal seeks NRL's in-principle consideration — with a joint working group on land, utilities and offtake term sheets, CSR committee evaluation, and a letter of comfort to support the Government of Assam MoU and financial closure as the requested next steps.
Circular by design — zero waste
Biogas → CBG under GOBARdhan, proposed for 100% NRL offtake.
Fermentation CO₂ → cryogenic dry ice for SICGIL — a climate liability made carbon-negative.
Solids → FOM, liquids → LFOM — nutrients return to Assam's farmlands, closing the runoff cycle that feeds the weed.
Tail gas + solar → captive power; every tonne harvested is monetised four ways.

Carbon Credits Programme
Every plant earns twice — once from its products, once from its carbon.
Bokakhat's VCS + Gold Standard nature-based credits (₹5.2 Cr in Year 1, on a trajectory toward ₹867 Cr by Year 10 with replication), Veppur's CCTS portfolio worth ₹50–80 Cr by Year 5, and Palani — India's first CBG plant creditable on both methane and CO₂ capture under Article 6.2. Carbon income is excluded from every bankable base case: each credit rupee is pure upside.
Own 250+ acres? Grow Giant King Napier Grass — and co-own a BioCBG plant.
YGPL invites landowners across India with 250 acres or more who are willing to cultivate Giant King Napier Grass as energy feedstock to become partners in a BioCBG plant — anywhere in India. A conglomerate of farmers qualifies too: we handhold you to float a Farmer Producer Organisation (FPO), help you cultivate, arrange cultivation loans, and purchase your Napier Grass on long-term contracts — with land convertible into plant equity, as at Palani.
