The Assam Programme — Water Hyacinth BioCBG at Bokakhat and Beyond

Assam — where the world's worst aquatic weed becomes the state's newest industry.

The Integrated Water Hyacinth Circular BioCBG cum Cryogenic Dry Ice Complex at Bokakhat is the anchor: the first large-scale plant anywhere on water hyacinth and bamboo feedstock — likely the largest in the world of this kind — presented to the Hon'ble Chief Minister of Assam and developed alongside Numaligarh Refinery. From Bokakhat, the programme extends to four further locations across Assam, on the path to a 50-unit statewide replication and India's first carbon-positive state.

Changing the Sustainability of Assam

Every tonne of the invasive weed harvested at 1,200 TPD becomes CBG (NRL, GOBARdhan price), cryogenic dry ice (SICGIL), and FOM & LFOM organic fertilisers (Prabhat) — four LOI-backed streams worth ₹199.98 Cr a year, while the Kaziranga buffer beels restore naturally within about 18 months.

What Bokakhat proves

Harvesting beats regrowth — for the first time in 130 years, industrial removal at 1,200 TPD outpaces the weed's biology.
Circular economics hold — 74.9% EBITDA margin and a 2.5-year payback make restoration self-funding.
Communities recover — fishing incomes climb back from the 64% crash; 18,000 ha of wetland restored.
The NRL template works — land, utilities, offtake and CSR from an anchor PSU, replicable at every future site.

The replication pathway

Four further locations across Assam follow the Bokakhat template in the four-site Bio Refinery initiative.
50-unit programme (2030–33) — funded from project accruals, without dilution or fresh government support.
Skill pipeline — the Bokakhat Skill Development Centre trains 450+ locals a year for every future site.
The destination — statewide beel restoration and India's first carbon-positive state.

The full Bokakhat project — crisis, process, lifeline, NRL partnership and funding — is detailed on the Yogan Green Bokakhat page.
