Ground crews that confirm satellite methane plumes at landfills and plan the fix
TL;DR Ventsure watches public and paid methane satellite data over Indian landfills, sends a crew with handheld detectors when a plume appears, and pins down the cracked cover, fire or vent behind it. Landfill operators and city corporations pay per site per year for the leak map and a costed fix plan.
Satellites can now see Indian landfills leaking methane. In 2025 data from a non-profit methane-mapping coalition, two of the world's 25 largest landfill emitters were in India, at Secunderabad and Mumbai, and the top sites emit 3.6 to about 7.5 tonnes of methane an hour[1]. Delhi's Ghazipur released more than 400 tonnes an hour in one 2022 event[1].
Seeing a plume from space is not the same as fixing it. Many Indian landfills were built without liners or gas collection, and the clean-up drive under Swachh Bharat Mission 2.0 has paid little attention to landfill gas[2]. Operators named in the satellite reports often have nobody on staff who can find the exact source.
What it does, in regulatory terms: emissions measurement and advisory services, with no gas capture or credit issuance. Landfill gas duties sit with the operator and the city under the Solid Waste Management Rules 2016[3].
The seed proposed launching hyperspectral satellites. Non-profit, commercial imaging and methane-monitoring fleets already fly them[4][5], so I reframed it to the part they leave undone in India - the ground.
Ventsure screens every satellite pass over its client sites. When a plume shows up, a two-person crew walks the site within days using laser methane detectors and a drone, and maps leaks to specific features such as cover cracks, smouldering cells, leachate pools or failed vents. The report ranks fixes by tonnes saved per rupee, like patching the cover, adding a flare or extending biomining to a hot cell. A repeat survey after the work shows whether the plume shrank, which is proof the operator can show to the city and the pollution control board.
The payer is the landfill operator holding the city contract, such as the waste firms named in the 2026 satellite analysis[1], or the municipal corporation itself. Both look bad when their site is named in national media. Data access is cheaper than it looks, because the non-profit coalition allows non-commercial use by operators and governments, though commercial resale needs a licence[4]. There's no public price for this service, so ₹8–20 L per site per year is my assumption.
The plume lists are public and dated. The April 2026 report named Indian sites and operators by name[1]. The 2016 rules already require gas control and forbid venting[3], so a named site has a compliance problem, not just a reputation one.
There's no public figure for landfill methane services in India. The narrow anchor is at least two Indian landfills among the world's top 25 emitters in 2025, out of 707 waste sites worldwide with observed plumes[1]. Landfills were already over a quarter of Mumbai's methane in earlier work[2]. Count client sites bottom-up.
A Canadian firm sells satellite and aircraft methane monitoring, with landfills as a named sector[5]. The non-profit coalition publishes plume data for public use[4]. Neither sends crews onto Indian landfills or writes fix plans. Landfill gas consultants exist globally, but I found none in India combining satellite alerts with ground surveys and follow-up checks after repairs.

The kit is off-the-shelf. The hard part is getting permission to walk a hot, unstable dumpsite, keeping crews safe from fires and gas, and turning findings into fixes operators will actually fund. Satellite passes are irregular too, so a plume seen once may be gone by the time your crew shows up.
There's no licence to run methane surveys, but your clients' duties and your data and drone use bring rules.
Building this outside India? The categories above usually have a local equivalent, so check with your own regulator.
Don't trust AI on emission totals or on crew safety. Satellite estimates are uncertain, and decisions about walking a burning, unstable dump stay with the crew on the ground.

I like this one, because the data is already free and nobody is doing the dirty work. It suits a founder from environmental engineering or landfill operations who can sell to city officials and waste contractors. If you want a pure data business then this isn't it. Prove first that one named operator will pay for a survey and act on at least one fix.
Plan for about ₹55 L–1.2 Cr for detectors, a drone, trained crews and data licences.
No survey licence, but you need drone registration, the right terms for any satellite data you resell, and an understanding of the operator's duties under the Solid Waste Management Rules 2016.
Yes. Satellite plume data covers landfills worldwide, and the ground follow-up gap exists in many countries. Check local waste and drone rules first.

Thinking about building Ventsure or something close to it? The make-or-break work is getting a named operator to let a crew onto its site and pay for the fix plan, and I can help you shape that first pitch. If you need a hand, you know where to find me. Talk to Yash →
