Biogas plants run on site for hotel kitchens, paid monthly for the gas they make
TL;DR Kitchengas installs, owns and runs small biogas plants at hotels, hostels and large canteens. Kitchen waste goes in, and gas goes back to the kitchen burners through a meter. The client pays nothing upfront and a monthly fee tied to gas delivered, which is cheaper than the commercial LPG it replaces.
Big kitchens make more wet waste than they can handle. A 100-room hotel can produce 700–800 kg of garbage a day while its own facilities process only 100–200 kg[1]. Smaller hotels and hostels often have no processing at all[1].
And that gap now comes with a penalty.
Since 1 April 2026, any site producing 100 kg of waste a day counts as a bulk waste generator under the Solid Waste Management Rules 2026[2]. It has to process wet waste on site or get a certificate, and pays higher landfill fees if it doesn't[3]. The very same kitchens also buy commercial LPG, and India had 37.1 lakh non-domestic LPG customers on public-sector books in July 2026[4].
What it does, in regulatory terms: on-site processing of wet waste under the SWM Rules 2026, with the gas burnt in the client's own kitchen and not sold as fuel. Local body approvals and pollution board consent may still apply, so check both before you install.
Kitchengas fits a compact digester, sized to the site's daily waste, in a service yard or on a terrace. Kitchen staff drop segregated food waste into a feed chute. The plant makes gas that runs through a meter to one or two dedicated burners, usually the ones doing long boils like dal or stock. Kitchengas owns the plant, sends a technician on a fixed schedule and keeps an eye on gas output remotely.
The original idea was to sell on-site biogas plants. The trouble with selling hardware is that the client ends up with a plant that dies the moment nobody feeds or maintains it properly. Owning and running the plant and billing for metered gas puts that risk on the company that knows how to manage it.
Hotels with 50–300 rooms, college and corporate hostels, hospital kitchens and large canteens pay. The facilities manager signs, and the pitch rests on two savings - wet-waste disposal and LPG.
Your monthly fee should sit below the LPG it replaces plus current hauling costs, so check both on the client's own invoices. MNRE's biogas programme offered capital support for plants above 25 cubic metres a day in its first phase[5].
The SWM Rules 2026 kicked in on 1 April 2026 and made on-site wet-waste processing the default for bulk generators[2][3]. Commercial LPG is also a cost line every hotel kitchen can see. MNRE's biogas programme ran its first phase from 2021-22 to 2025-26[5], so check whether a second phase is open.
Nobody publishes a count of Indian kitchens that qualify as bulk waste generators. The firmest anchors are 37.1 lakh non-domestic LPG customers on public-sector books, with commercial use at 9.3% of LPG sold in April–June 2026[4].
Lab studies get roughly 112–152 cubic metres of methane per tonne from food waste fractions[6]. Field output will be lower, so measure it yourself.
One Bengaluru clean-fuel company built small biogas plants for urban organic waste and reports diverting about 9,400 tonnes of it[7]. It has since shifted to compressed biogas and other fuels at larger scale[7]. Plenty of smaller vendors sell on-site composters and digesters outright.
I couldn't find an Indian company that owns and runs kitchen biogas plants at client sites and bills only for metered gas.

The digester is known technology. The hard parts are capital, because you pay for every plant, and service discipline across lots of sites. Gas output depends on kitchen staff segregating waste properly every single day, which you can't control directly. Expect a slow first year while you learn each kitchen.
There's no single biogas licence, but waste rules and local approvals shape every install.
Building this outside India? The categories above usually have a local equivalent, so check with your own regulator.
Don't trust AI with gas safety calls. Leaks and pressure faults need a trained technician on site.

Here's what can go south -
I think this suits an engineer with biogas or facility-services experience and access to project finance. If you want a light, quick-to-scale business then it's a poor fit.
Prove one thing first - that a 300–500 kg a day plant delivers enough metered gas each month to beat the client's LPG bill, three months in a row.
Plan for roughly ₹1.2–2.2 Cr, because you pay for every plant you install and own at a client's site.
It can be if each plant makes enough metered gas to beat the client's LPG bill month after month. Prove that on one site before you scale.
Yes, wherever kitchens pay to dispose of wet waste and buy gas. Check your local waste rules and gas safety codes first.

Thinking about building Kitchengas or something close to it? The make-or-break work is financing plants you own and keeping gas output steady when kitchen waste is messy, and financing plans like that are a big part of what I do. If you need a hand, you know where to find me. Talk to Yash →
