How to Get Fly Ash from Thermal Power Plants: WBPDCL/DVC MoU and the New 2026 Free-Delivery Rules

The most interesting part of the fly ash brick business ledger is this: the main raw material costs almost nothing — to a thermal power plant this ash is waste, and they spend money to dispose of it. But collecting ‘waste’ is itself a whole process — knowing the legal route, the paperwork and the new 2026 rules is essential, or you will fall into the middleman’s net.

The rules are actually on your side

Under the Environment Ministry’s (MoEFCC) fly ash utilization notification, all construction activity within 300 kilometres of a coal/lignite thermal plant must use fly ash-based products — meaning almost all of Bengal’s rice plains are this business’s market. And on the supply side, the Power Ministry’s revised guidelines of 30 January 2026 have directed plants to give ash free, with notice, to buyers within 300 km and to bear the transport burden — good news business-wise, though actual implementation varies by plant.

West Bengal’s main fly ash sources

Plant	Location	Authority
Kolaghat (KTPS)	Purba Medinipur	WBPDCL
Bakreswar (BKTPP)	Bankura	WBPDCL
Sagardighi	Murshidabad	WBPDCL
Bandel	North 24 Parganas	WBPDCL
Santaldih	Bankura	WBPDCL
Durgapur Thermal	Paschim Bardhaman	DVC
Mejia	Paschim Bardhaman	DVC

Being near a plant = lower transport cost = higher margin per brick. That is precisely why the number of new brick units in the Purba Medinipur–Panskura belt next to Kolaghat is rising fast.

Steps to getting the MoU

1. Prepare your unit’s identity papers — Udyam registration, a WBPCB CTE application reference and the plant’s capacity details. Bare-handed approaches don’t work.
2. Letter to the plant’s ash-management/utilization cell — on company letterhead, stating the required tonnage (daily/monthly), purpose of use and collection method.
3. Sign the supply agreement/MoU — spell out in writing the tenure, tonnage, handover point, and responsibility and rate for transport.
4. Gatepass and weighbridge arrangement — a gatepass for every bulker; record weights measured at the plant’s weighbridge.
5. Arrange bulkers (tippers/tankers) — for dry ash, enclosed bulkers are better (less dust pollution and loss); budget hire on a per tonne-km basis.

Dry ash, pond ash and bottom ash

• Dry fly ash (ESP): ideal for the brick mix — fine and consistent. From the silo into bulkers.
• Pond ash: from the ash pond; available free or nearly free, but wet and unevenly grained, adding uncertainty to the mix. Mostly used in backfilling of large construction projects.
• Bottom ash: not used directly in bricks; some units use it as a partial substitute for sand/stone dust.

Three middleman traps

1. ‘Ash lock’ commission — a promise to lock in ash supply for a monthly ‘commission’; there is no legal private commission system at plants.
2. Gateless gatepass — if a truck enters the plant gate without papers, liability for smuggling is yours; with the police and the board.
3. Underweight billing — no payment without your own portable weighbridge or a photo of the plant’s weighbridge slip.

Fold this into your financing

Mentioning this raw-material sourcing structure in the DPR makes bank approval easier — see the PMEGP loan guide. You will need clearance before the ash arrives — read the WBPCB CTE guide.
