Biomass Pellets for Morbi’s Ceramic & Tile Kilns: The Fuel Security Guide for 2026

Morbi runs on fire. Behind every tile that leaves this small Saurashtra town for Hyderabad, Mumbai, Delhi, or a container ship headed overseas, there’s a tunnel kiln burning at roughly 1,200°C, 24 hours a day, for weeks at a stretch. That heat has always come from two sources — piped natural gas and trucked-in propane. In 2026, both sources became unreliable at the same time, and hundreds of factories across the cluster were forced to halt production almost overnight.

If you run, manage, or supply fuel to a ceramic or tile unit in Morbi, you already know this story better than any article can tell it. What this guide is for is the part that comes next: what a factory actually does about it. Biomass pellets and briquettes are not a theoretical “green” alternative here — they are one of the few realistic ways to put continuous, storable, budget-stable heat back under a kiln that cannot afford to go cold.

This is a long, detailed guide. Skip to whichever section answers your immediate question, or read it start to finish if you’re building a fuel strategy for the next year.

Most industrial towns in India run on a mix of fuels. Morbi, for decades, largely did not. The cluster built its entire thermal backbone around natural gas and propane because both were, for a long time, cheap, clean-burning, and easy to pipe or truck into a compact geographic cluster of 600-plus factories.

That concentration is exactly what makes the cluster fragile. When pipeline gas allocation tightens or global propane prices spike, there is no local fallback fuel infrastructure sitting ready to absorb the shock. A kiln that loses its gas supply doesn’t slow down gracefully — tunnel kilns need a continuous heat curve to avoid cracking the ware inside them, so a fuel interruption often means a full production halt, not a partial one.

The result, as the industry has felt through parts of 2026: hundreds of units idle at once, tile prices moving up by several rupees per square foot within weeks, and buyers outside Gujarat starting to feel the supply tightening. Larger, diversified players who already run a mixed fuel strategy — gas plus biofuel, gas plus coal, or kilns engineered for fuel flexibility — have weathered these swings with far less disruption than smaller single-fuel units.

That’s the structural lesson for every factory owner in the cluster, independent of how this particular gas cycle resolves: a kiln that can only burn one fuel is a kiln with one point of failure.

The obvious instinct when gas gets expensive is to switch to coal or a coal gasifier — it’s cheap, energy-dense, and was, for years, a standard secondary fuel across Indian ceramic clusters.

In Morbi specifically, that door has largely closed. Following pollution concerns tied to dense clustering of coal gasifier units, regulatory action was taken against coal gasifier operations in the cluster, and enforcement around emissions compliance in and around Morbi has only tightened since. Even where coal remains technically available through state mineral development allocations, running it inside a cluster under active environmental scrutiny carries real regulatory risk — inspection stoppages, compliance notices, and reputational exposure with export buyers who increasingly ask about emissions.

That leaves a gap: factories need a second fuel that behaves like coal in the furnace — high calorific value, dense, easy to store and feed continuously — without carrying coal’s compliance baggage. This is precisely the gap biomass pellets and briquettes are built to fill.

Biomass pellets and briquettes are compressed, moisture-reduced fuel made from agricultural residue — groundnut shell, cotton stalk, coriander waste, mixed agro-residue — processed under high pressure into a dense, uniform, easy-to-feed form. For a ceramic kiln operator, what matters is not the “eco-friendly” label; it’s whether the fuel performs.

High and consistent calorific value. Quality biomass pellets typically deliver a Gross Calorific Value in the range of roughly 3,800–4,400 kcal/kg depending on the base material and moisture content, which is close enough to standard industrial coal to serve as a genuine thermal substitute in co-fired or biomass-primary kiln setups. (See our detailed breakdown of how GCV is measured and why it matters more than price per kilogram, in our GCV guide.)

Low ash, low moisture, cleaner combustion. Properly manufactured pellets run low single-digit ash content and low moisture, which means less clinker buildup inside kiln chambers, less manual de-ashing downtime, and more predictable combustion behaviour batch to batch — a bigger deal in a continuous tunnel kiln than it sounds.

No import exposure. Unlike propane and, increasingly, gas allocations that are exposed to global shipping routes and geopolitical disruption, biomass pellets are made from domestic agricultural residue — much of it sourced within Gujarat itself. That means the fuel supply for your kiln isn’t hostage to a shipping lane thousands of kilometres away.

Price stability. Biomass raw material pricing tracks domestic agricultural cycles, which move in a far narrower band than international gas and propane pricing. That doesn’t mean biomass is always the cheapest fuel on a given day — it means the price you budget for in January is a lot more likely to still be roughly true in July.

Storable in bulk. Pellets and briquettes can be stockpiled in a dry, ventilated warehouse for well over a year without meaningful quality loss. A propane truck delay is a crisis. A three-week buffer stock of biomass sitting in your yard is not.

Switching a 1,200°C continuous tunnel kiln onto a new fuel is not a weekend project, and any supplier who tells you otherwise is not being straight with you. Here is the realistic path factories in the cluster are actually taking.

Most Morbi kilns were engineered around gas or propane burners. The first question isn’t “can we use biomass” — it’s “in what proportion, and through what burner or feed modification.” A co-firing setup (biomass supplementing gas rather than replacing it outright) is the lowest-risk entry point for almost every factory we’ve worked with.

Run a controlled trial — typically two to four weeks — blending biomass pellets into your existing thermal load at a modest ratio (commonly starting around 15–25% of thermal input) while your team measures kiln temperature stability, ash behaviour, and ware quality against your existing benchmarks.

Biomass needs dry, covered storage and a feed system suited to pellet or briquette form factor — different from a gas line, but far simpler than most factories expect. We help clients right-size storage against their monthly tonnage before the first delivery, not after.

The single biggest mistake factories make when switching fuel is buying on price per kilogram without a written GCV and ash-content guarantee. A cheaper pellet with lower calorific value and higher ash can cost you more per unit of actual heat delivered — and can damage kiln refractory lining over time. Always contract on a spec, not just a price.

Once a trial confirms stable kiln performance, most factories increase the biomass share of their thermal mix in stages over two to three production cycles rather than switching all at once — protecting both product quality and the ability to fall back if any adjustment is needed.

The real win here isn’t “biomass instead of gas.” It’s a factory that can flex between two or three fuel sources depending on what’s available and what’s priced sensibly that month — which is exactly the resilience the larger, diversified players in the cluster already have.

Exact landed fuel costs shift week to week with gas allocation, propane import pricing, and monsoon-driven agricultural residue availability — so treat the figures below as an illustrative comparison of cost drivers, not a quote. Always ask any supplier, including us, for current pricing against your specific tonnage and delivery location.

The pattern that matters most for a Morbi factory owner: biomass sits in the one quadrant fossil fuels can’t reach — reasonably high heat output and low structural supply risk. That combination is worth more during a gas crisis than a marginally cheaper fuel that might not arrive at all.

Morbi doesn’t just sell tiles domestically — a meaningful share of the cluster’s output moves through export channels to markets that increasingly scrutinise a supplier’s environmental footprint before signing procurement contracts. Anti-dumping protections that have supported Indian tile exports into markets like the US only hold value if buyers keep choosing Indian suppliers over other origins — and emissions credentials are becoming part of that decision, not a side note.

A factory that can show a documented shift toward renewable biomass fuel, even as a blended input alongside gas, has a genuine story to tell export buyers and auditors that a coal-dependent competitor increasingly does not. This isn’t about chasing a certification for its own sake — it’s about staying commercially competitive as buyer-side environmental due diligence tightens year over year.

Fuel switching decisions live or die on logistics, not just chemistry. This is where geography works in Morbi’s favour if the supplier is right.

Pellexion Bio Energy’s manufacturing facility sits in Kharedi, Kalavad, in the Jamnagar district — inside the same Saurashtra industrial belt as Morbi, roughly an hour’s transit away rather than the multi-day hauls that stretch propane and imported coal supply chains thin. For a factory that just lived through weeks of production loss because a fuel truck couldn’t reach the gate on time, “an hour away” is not a minor detail — it’s the difference between a fuel buffer that actually protects you and one that’s a story you tell yourself.

We source raw material — groundnut shell, cotton stalk, coriander residue, and mixed agricultural waste — from farms across Gujarat’s agricultural belt, which keeps both the supply chain and the pricing regional rather than tied to global shipping routes.

“Will biomass hold the 1,200°C my kiln needs?” Yes, when GCV and feed rate are correctly specified for your kiln’s design — this is exactly why Step 1 of any switch is a kiln audit, not a blind fuel swap. High-quality pellets in the 3,800–4,400 kcal/kg range, fed at the right rate, sustain the continuous high-temperature curve tunnel kilns require. What fails is under-specified fuel, not the fuel category itself.

“Will it change our tile quality or firing consistency?” Not when the transition is trial-tested and scaled in stages, as outlined above. Ash behaviour and combustion consistency are the two variables that matter for ware quality, and both are measurable in a two-to-four-week trial before you commit to a larger ratio.

“What if biomass supply runs short in monsoon?” This is a fair concern — agricultural residue supply does have seasonal rhythm. The answer is contracted, forward-stocked supply rather than spot buying. We work with factories on monsoon-buffer stocking specifically so a seasonal dip in fresh residue never becomes a kiln-side fuel gap.

“Isn’t this just a smaller-scale version of what Kajaria and Somany are already doing?” Essentially, yes — and that’s the point. The larger, more resilient players in the cluster have been running diversified, partly biomass-inclusive fuel strategies specifically because it reduces their exposure to exactly the kind of single-fuel shock the cluster experienced in 2026. This guide exists so mid-size and smaller units can access the same resilience without needing a large corporate energy team to build it.

No factory should commit to a full fuel switch on the back of a sales call. This process is deliberately built so you’re making every decision on your own kiln’s actual data.
