Truck-by-truck proof that a power plant's ash reached an authorised user
TL;DR Ashtrace gives coal power plants a trip-level record of every ash truck - weighbridge slip, vehicle, route and a signed receipt at the user's site. That record is exactly what auditors and pollution boards want under India's 2021 ash rules. Plants pay per tonne tracked, and small brick and block makers find ash through the same system.
India's coal and lignite plants produced 270.82 million tonnes of fly ash in 2021-22 and reported using 95.95% of it[1]. They also had 1,734.02 million tonnes of older ash sitting in ponds[1]. The 2021 ash notification requires each plant to use all its ash on a three-year average and to clear old stocks within ten years[2].
Every link in the chain now carries a penalty.
Plants under 80% utilisation pay ₹1,000 per tonne of unused ash. Transporters who drop ash with an unauthorised user, or don't deliver it at all, pay ₹1,500 per tonne and face prosecution. Users who fall short of their obligation pay ₹1,500 per tonne too[2]. Yet the national monitoring app collects monthly plant totals and not individual trips[1], so a plant's "utilised" figure sits on paper challans that are easy to dispute.
What it does, in regulatory terms: record-keeping and evidence only. Ashtrace does not transport ash, certify compliance or act as an auditor. CPCB keeps its own list of authorised auditors[3]. The plant stays legally responsible for its numbers.
Here's the flow - every truck gets a digital trip at the plant weighbridge with weight, vehicle number, destination and the user's authorisation. The driver's phone app or the truck's existing GPS logs the route. At the site the receiver confirms the weight and photographs the unloading, and the trip closes. Records are signed and time-stamped so nobody can quietly edit them later. Plants get a dashboard that matches trips to their reported utilisation, ready for an audit.
The other side is matching. Brick, block and ready-mix makers within 300 km can see which plants have ash and book loads, which helps plants sitting on legacy stocks.
I reframed the seed, which pitched a blockchain exchange for all industrial waste. The weak point in ash tracking is the data captured at the weighbridge and the unloading point, not where it gets stored, and a signed log fixes that for a lot less money. Blockchain would be overkill here, in my opinion.
The plant's ash management team pays, either per tonne tracked or as an annual fee per station. I found no public price for ash tracking services, so test both. Large transporters may pay a small fee to prove clean delivery and stay clear of the ₹1,500 charge. Brick makers get the matching side for free at first.
The three-year compliance cycles under the 2021 notification, as amended in 2022 and 2024, are running now[2]. CPCB issued directions to state boards in October 2024 and named authorised auditors the same year[3]. Its central working group was still meeting in April 2026[3]. Audits create demand for records that hold up.
The narrowest figure is 1,734.02 million tonnes of legacy ash at 200 plants as of March 2022[1], all of which must move within the ten-year window[2]. Annual generation of 270.82 million tonnes is broader context[1]. I found no figure for spending on ash logistics or tracking.
ASH TRACK, built by CEA with NTPC, collects monthly generation and utilisation data from plants[1]. A European chain-of-custody software firm tracks materials for large carmakers and chemical groups[4], but not Indian ash. Large plants run their own dispatch software. I didn't find an independent Indian service that proves each trip end to end. My search was limited though, so check before you start.

The tech is ordinary and cheap to build. The hard part is getting drivers and receivers to use an app on rough sites with weak signal, then wiring into plant weighbridges and selling to public-sector utilities whose tender cycles can drag past a year.
The software itself needs no sector licence, but your buyers live under a tight rulebook, and your records have to fit it.
Building this outside India? The categories above usually have a local equivalent, so check with your own regulator.
Don't let AI decide whether a plant is compliant or whether a transporter gets penalised. Those calls belong to the plant, the auditor and the pollution board, with the raw records in front of them.

Here's what can go south -
I'd back this for a founder who has sold software to power utilities or run bulk logistics in the coal belts. If you're expecting fast sales then look elsewhere. Start with private and captive plants, which move faster than state utilities. Prove two things first - that one plant will pay to track all its ash trucks for three months, and that over 95% of its trips close with a receiver's signature.
Plan for roughly ₹60 L–1.2 Cr. Most of it goes on building the app, wiring into weighbridges and a long sales cycle with power plants.
No licence covers the software itself. You need company registration, GST and DPDP compliance for driver data, and your records must fit the 2021 ash notification and CPCB audit format.
Yes, wherever coal plants or heavy industry must prove where their by-products go. Check your local waste rules first, because the trip record has to match what your own regulator audits.

Thinking about building Ashtrace or something close to it? The make-or-break work is getting the first plant to put every truck on the system, not just a pilot route, and I've helped founders through that kind of sale before. If you need a hand, you know where to find me. Talk to Yash →
