Finds a legal reuse route for factory waste that now goes to landfill
TL;DR Wastematch works with chemical, dye and pharma units that pay good money to send hazardous waste to a landfill or incinerator. It checks each waste stream against CPCB's approved reuse procedures, finds an authorised user nearby and runs the permits and manifests. Generators pay out of what they save on disposal.
Indian factories reported 19.02 million tonnes of hazardous waste in 2024-25, up about 74% in five years[1]. CPCB called 7.73 million tonnes of it utilizable and 3.21 million tonnes fit only for landfill. Gujarat alone made 46% of the national total.
A lot of utilizable waste still goes the disposal way.
A spent acid or a salty sludge can legally become feedstock for another plant only when a procedure exists for it and the receiving unit holds the right authorisation[2]. Finding that unit, getting lab reports that match the procedure and filing the papers is slow, boring work. Compliance is patchy too - just 65.79% of the 95,524 generating units filed their annual returns for 2024-25, and in Gujarat it was 42.76%[1].
What it does, in regulatory terms: matching and compliance support only. Wastematch does not collect, store, transport or process waste. Authorised transporters and users do that under Rule 9 of the Hazardous and Other Wastes Rules 2016[2]. Nobody has said clearly whether a matching service needs a Form 2 authorisation of its own, so ask the SPCB before you launch.
Here's how it works. A generator uploads its waste analysis and annual return, and the software reads the lab report and checks it against CPCB's standard operating procedures, which now cover more than 120 waste-to-product routes, from spent hydrochloric acid into calcium chloride to aluminium dross into briquettes[3]. A chemist checks every proposed match. Wastematch then lines up an authorised user in the same state, books an authorised transporter and gets the documents ready.
I reframed the seed, which pitched AI matching across all industrial waste. Software can suggest a match in seconds, sure. But a match is legal only where an SOP covers that waste and the receiver holds the permit, so the product is mostly paperwork, testing and trust, with AI there to read reports fast.
The person who pays is the environment or plant head at a mid-sized chemical or pharma unit, the one signing disposal bills today. I couldn't find a published national TSDF tariff, so measure each client's current cost per tonne and charge a share of the saving per tonne you divert. Utilisers can pay a small sourcing fee. For a price yardstick, one European surplus-materials platform charges €5,500 (about ₹6 L) for a four-week onboarding of up to 50 materials[4].
CPCB put out the 2024-25 inventory in May 2026, and it shows utilizable waste going up while landfillable waste fell from 3.56 to 3.21 million tonnes[1]. The SOP list keeps getting longer, and recent additions include lithium-ion battery black mass[3]. SPCBs now sit on five years of state-level data on who generates what, which makes clusters easy to target.
The narrowest number is the 7.73 million tonnes of hazardous waste CPCB called utilizable in 2024-25[1]. Some of it is already reused in-house or sold, and I found no public figure for the share that still goes to disposal. Treat the 19.02 million tonne total as context, nothing more. Gujarat, with 14 common TSDF sites, is the obvious first state[5].
A UK industrial-symbiosis firm runs a matching tool it says is used in 30 countries[6]. Another European platform sells a surplus-materials marketplace to European firms[4]. In India, TSDF operators are the default route, and they make money from landfill and incineration, not from diverting waste. I didn't find an Indian service focused on Rule 9 matching. My search was limited though, so check before you start.

| Starting capital | ₹55 L–1.1 Cr |
| Time to launch | 6–9 months |
The software is the easy bit. The hard parts are a chemist who knows the SOPs inside out, steady lab testing and SPCB officers who trust your files. Every match also needs a receiving plant that's happy to take a feedstock whose quality changes from batch to batch.
Possibly. Whether a matching-only service needs its own authorisation is still an open question.
Building this outside India? The categories above usually have a local equivalent, so check with your own regulator.
Don't let AI approve a match. Whether a waste legally fits an SOP is a chemist's call and an SPCB decision, and getting it wrong puts your name on the paperwork.

Here's what can go south -
I think this is worth a shot for someone with chemical-industry or SPCB compliance experience who already knows a Gujarat cluster. It is not for a pure software team. Before you raise money, prove you can move one waste stream from landfill to an authorised user within 60 days, and that the saving per tonne holds up after testing and transport.
Plan for roughly ₹55 L–1.1 Cr, mostly for a compliance chemist, lab testing and the software that reads reports.
It isn't settled. Every receiving unit needs Rule 9 authorisation, and you should get a written SPCB opinion on whether a matching-only service needs Form 2 authorisation.
Yes. Industrial-symbiosis platforms already work abroad. Local hazardous waste law decides what a legal match looks like, so start there.

Thinking about building Wastematch or something close to it? The make-or-break bit is getting the first SPCB-approved match through without a compliance scare, and that's the sort of thing I help founders work through. If you need a hand, you know where to find me. Talk to Yash →
